Kiwi Tree Care & Propagation Guide
Kiwi tree's fruit is known as the "king of fruits" because its vitamin C content is among the best in fruits. Kiwi tree's fruit also contains good soluble dietary fiber. In addition to high nutritional value and medical care, it also has high economic value and is known as "green gold mine". How to plant Kiwi tree scientifically and improve the yield and quality of Kiwi tree fruit is a problem of great concern to fruit farmers. First, the key points of Kiwi tree cultivation are introduced as follows for reference.

Kiwi Tree Care in Detail

Kiwi Tree Care & Propagation Guide

Kiwi Tree Watering

Kiwi tree likes water and is afraid of waterlogging. The main reason is that kiwi tree is a broad-leaved fruit tree. Especially in summer, the leaf transpiration is very strong and the water demand is relatively large. Therefore, it is generally required that the soil water content should be maintained at 70% in June, July and August. However, at the same time, the root system of Kiwi tree is fleshy root with strong respiration and requires more oxygen content in the soil, In other words, it is necessary to have the necessary soil permeability. Therefore, according to the growth and decline of soil water and gas, it is not allowed to water too much. This is a very contradictory unity. What should we do? Therefore, we should grow grass on the ground, increase the application of organic fertilizer and strengthen the soil water storage capacity.
In many orchards, there are a large number of unexplained dead trees in summer and autumn. In fact, the trees are watered, soaked and drowned. Kiwi tree will never die of drought, only waterlogging. Many fruit farmers have experience. In summer, if there is continuous rainfall, or if there is rainfall just after watering the ground, once the weather turns sunny, the temperature will rise quickly, and many Kiwi trees will wither immediately (commonly known as next noon). If they are not handled in time, kiwi tree will soon die. This is Kiwi tree's typical love of water and fear of waterlogging.
Kiwi tree has dense branches and leaves, shallow root distribution, and is neither drought resistant nor flood resistant. Therefore, kiwi tree Garden needs irrigation and drainage equipment, such as irrigation ditch, drainage ditch, drip irrigation, sprinkler irrigation equipment, etc. The economic water for Kiwi tree irrigation is drip irrigation, and the water supply is uniform; Sprinkler irrigation uses a large amount of water, but it also plays a great role. In addition to supplying the water required by the root system in summer, sprinkler irrigation also increases the air humidity and reduces the tree temperature. Sprinkler irrigation can prevent freezing in early spring, autumn and winter.

Kiwi Tree Soil

We hereby suggest that kiwi tree should be planted in gully type pits. Before that, we should first determine the distance between each row, and then determine the distance between each seedling after completing the above operations. The second method is that we can dig round caves for Kiwi tree planting. The same as the above method, the operation must be carried out after determining the line spacing. Either of the above two methods must be completed one month before planting plants. In this way, we are conducive to the cultivation of soil. The first method is suitable for areas with relatively flat terrain, not for mountainous areas. The width of trench excavation is generally about 1.5m and the depth is about 1m. The length of Kiwi tree depends on the planting quantity. While the old Kiwi tree is flowering, the surface soil and bottom soil shall be stacked on both sides separately. After the excavation, we should fertilize each sapling. The basic fertilizers are divided into soil, miscellaneous fertilizer, animal manure, straw, weeds, quicklime and phosphate fertilizer. These fertilizers were mixed with the soil in layers and buried in the excavated trenches. When covering Kiwi tree with soil, we should put the previously excavated topsoil at the bottom of the ditch, and then put the soil excavated from the bottom to the upper half of the gully. Then, the surface of the trench shall be earthed and about 15 cm higher than the surface. After completing this work, we can re measure the distance of seedlings to be planted. (Find more healthy fruit here.)

Kiwi Tree Light

When we pay attention to the illumination of Kiwi tree, we can choose the mountainous area with convenient transportation, sufficient illumination, water source, moderate rainfall and slightly high humidity, loose and well ventilated sandy loam or sandy soil, or hilly and mountainous areas rich in humus as the best garden. After the kiwi tree site is determined, the roads, irrigation and drainage system and fertilizer management room shall be planned first, and then the ventilation ditch of the planting land shall be planned. Kiwi tree is suitable for planting in hills and mountains with an altitude of 400 ~ 1200m. It should be within 10 ~ 15。 Gardens are built on sloping hills and mountains. Kiwi trees can also be planted with greenhouse racks. We need to heavily trim Kiwi trees in winter to renew and rejuvenate them in time. We also need to re apply base fertilizer to kiwi tree, flood and fertilizer, timely irrigation, and avoid sudden dry and wet to prevent fruit cracking.

Kiwi Tree Temperature

We should plant Kiwi tree from the end of winter to the beginning of spring, preferably two days before the rain, so that the soil is wetter and the survival rate of seedlings can be improved. Kiwi tree has high requirements for climate and environment. It likes a warm environment with adequate light and is not resistant to cold. Kiwi tree will not bear fruit in low temperature environment. Therefore, when planting, it depends on whether the climate in the area can meet the growth needs. If not, do not plant, and there will be no results.

Kiwi Tree Humidity

Kiwi tree likes to grow in warm and humid valleys. It requires relatively short sunshine time and is not very strict with the soil. When choosing Kiwi tree garden, it is better to build the garden in the areas with sufficient light, water source, moderate rainfall and slightly high humidity, loose and well ventilated sandy loam or sandy soil or hilly and mountainous areas with loose soil rich in humus.
Kiwi tree is a vine. We must erect strong and durable scaffolds immediately after planting to facilitate its growth and fruit. Kiwifruit planting mainly adopts T-shaped frame, fence frame, triangular frame, greenhouse frame, etc. The flat roof greenhouse frame is mostly used, and the original small-diameter trees can be used as live piles locally, plus some replaceable Bamboo and wood dirt. We need to use concrete piles at the key parts of Kiwi tree. The local frame height is 1.8m, and the 10-12 iron wire is vertically and horizontally crossed to form a "well" shaped network, with a spacing of about 60cm.

Kiwi Tree Fertilizer

Kiwi tree is a perennial vine fruit tree that needs more fertilizer, so its important material basis of early fruit, high yield, stable yield, high quality and long life depends on reasonable fertilization.
We can apply germinating fertilizer once from the end of February to the beginning of March. First loosen the soil around the kiwi tree tray, then spread it, and then turn it deep into the soil; Strip application can also be adopted, with a general ditch depth of about 20cm, and fertilizer and soil can be applied. Kiwi tree applies 0.1kg urea per plant. Apply Flower and fruit protection fertilizer + guaguozhuangdiling respectively before flowering, young fruit stage and fruit expansion stage of kiwi fruit to meet the physiological needs of fruit development, prevent Kiwi tree from weak flowers or falling flowers and fruits, improve the fruit expansion speed, strengthen fruits and increase color.
Kiwi tree is applied with organic fertilizer and chemical fertilizers such as quick acting nitrogen fertilizer before falling leaves from October to November after fruit picking. The application amount of base fertilizer in Kiwi tree accounts for 60% of the annual fertilization amount. Usually for young trees, 50 kg of rotten manure is applied to each plant, plus 0.25 kg of calcium superphosphate and 0.25 kg of potassium chloride. For adult fruit trees, apply 50-80kg rotten manure, 1kg calcium superphosphate and 0.2-0.5kg potassium chloride, or 1kg compound fertilizer to each plant.

Kiwi Tree Pruning

If the soil in the trenches or caves we dug before reaches the surface or is lower than the surface after settlement, we need to cultivate the soil of Kiwi tree again. This time, we need to take care that the soil of Kiwi tree only needs to be about 10 cm higher than the surface. When carrying out the next work, we must pay attention to the distinction between male and female seedlings. One person digs a small pit for Kiwi tree, and the other is responsible for putting Kiwi tree in the middle of the pit, stretching the root of the seedling by hand, then covering it with a layer of fine soil, and then gently tamping it by hand.
The above is the basic application means of how to Kiwi Tree Pruning, so we must see many details. Sometimes the success and failure are in a small detail. As long as we pay attention to the above steps and details, we can greatly improve the survival rate of Kiwi tree. In summer, gently remove the skin of Kiwi tree fruit and take a bite. The instant cool pleasure makes the hot summer no longer boring. On the contrary, people will enjoy the feeling of collision between the hot summer and the cool kiwi fruit. Well, do you look forward to planting Kiwi tree like me?

Kiwi Tree Repotting

Kiwi tree repotting is the most suitable time from 18 days to 22 days before bud germination. It mainly adopts the grafting method of single bud cutting. To select the grafting with fuller growth and smaller pith, you can cut the branch segment with one bud, which is about three to five centimeters long, and select the straight side to cut off the cortex, The best depth is to expose the xylem or the xylem with a slight band. Select the smooth side to cut the next knife. The length of the cutting surface is slightly longer than that of the connecting surface, and the depth is the same as that of the connecting surface. Kiwi tree repotting requires that the size of the rootstock should be basically the same as that of the rootstock. It should be noted that the layers of the rootstock should be aligned, and then wrapped with plastic grafted film.
We apply organic fertilizer to kiwi tree mainly from cow manure, pig manure and garbage fertilizer. Before fertilizing, heap retting method shall be adopted to make it fully decomposed and achieve balanced fertilization. After fertilizing Kiwi tree, we also need to cover it with a layer of soil to prevent rainwater from washing away the fertilizer. The application of accelerating fertilizer is conducive to the flowering of buds and promote the growth of new shoots. It is best to apply accelerating fertilizer before germination, mainly based on available nitrogen fertilizer and applied throughout the garden. Promote the application of fruit fertilizer after flowering can promote the rapid growth of fruits, preferably 20 to 25 days after falling flowers. We can apply some strong fertilizer to kiwi tree, which can enrich the interior of the fruit, increase the weight of the fruit and improve the quality.

Kiwi Tree Pest & Disease Control

The main diseases of Kiwi tree are anthrax and brown spot. The pests of Kiwi tree are flower bud maggots, beetles and fruit sucking night moths. It is necessary to strengthen the management of orchards, enhance the vigor of trees and strengthen the disinfection of soil, mainly focusing on prevention.

Kiwi Tree Cutting Propagation

In fact, kiwi tree is the best choice for Kiwi Tree Cutting Propagation before the beginning of spring at the end of winter. It is suggested that kiwi tree should be planted 2-3 days before rain, because the survival rate of seedlings can be greatly improved in this case. The latest planting time of this Kiwi tree should be before the spring warms up. The survival rate will be reduced to a certain extent if it is planted after sprouting and rooting. (Find more Winter Fruit here.)
In the early spring, the rain season comes early and rains frequently. We should choose the cloudy day before the rain or the sunny day after the spring rain for fixed planting of Kiwi tree. If we choose to plant in wet and muddy weather like rain or after rain, the root development of Kiwi tree seedlings will be slow and the quality will be very poor, which will seriously affect the survival probability of Kiwi tree. At the same time, such weather is also very unfavorable to our field operation. In the northern part of our country, kiwi tree is best planted from years later to before bleeding, which is the best planting period. In general, it's best not to plant seedlings whose roots have matured or branches have grown to a certain extent. The survival rate of such Kiwi tree is very low.

Kiwi Tree Division Propagation

First of all, we should confirm the spacing of each row of seedlings: Kiwi Tree Division Propagation should be determined according to its type, selected land quality, geographical location, terrain level, quality of irrigation water source and different management methods. In areas with relatively flat terrain in our country, the planting degree can be sparse, while in mountainous areas or areas with relatively undulating terrain, the planting can be dense. It can be planted sparsely in areas with more nutrients. Two rare places can be planted more intensively. We can also adjust the density according to the length, thickness and variety of Kiwi tree. Because in the final analysis, there is no good in planting this plant too intensively. In many areas, kiwi tree is planted too intensively, resulting in fruit displacement, weak branches and stems, dead inner bore branches and leaves, premature growth and aging of trees, which should be paid attention to when we plant Kiwi tree.

Kiwi Tree Varieties

Hardy Kiwis 

This kind of Kiwi Tree Varieties are one of the newer vines developed for cooler season growing. These kiwi vine varieties are perfect for regions with light frosts and short growing seasons, such as the Pacific Northwest. They are hairless, green and small but pack a lot of flavor and are tolerant of conditions that the fuzzy kiwi cannot withstand.

Fuzzy Kiwis 

This kind of Kiwi Tree Varieties is the most common kiwi found in grocery stores. It is only hardy in areas with mild winters.

Arctic Kiwi Plant Types 

This kind of Kiwi Tree Varieties is the most cold tolerant of the different varieties of kiwi. It has extremely hardy fruit and pink and white variegation on the leaves, making it an attractive addition to the landscape. Fruits are smaller and sparser than the other kiwi vine varieties but sweet and delicious. Krupnopladnaya has the largest fruit and Pautske is the most vigorous of the Arctic kiwis. Each of these does need male pollinators to produce fruit.

Kiwi Tree Benefits

The excellent varieties of Kiwi tree are particularly delicious. Kiwi tree fruit is softer, waxy and sweet than ordinary kiwi fruit in the morning. Water is rich and colorful. Kiwi tree fruit also contains many carbohydrates and vitamins, which are generally fresh fruits. None, especially dimension C. Vitamin and selenium account for a very high proportion, which is called the first of vitamin C. They are especially high-end beings in fresh fruit.
Moreover, kiwi tree fruit has many functions and can not only be eaten directly as fruit. Let's supplement a lot of nutrients. We can also make it into small snacks such as canned fruit and preserved fruit, so that we can eat it all the year round.
In addition, kiwi tree fruit is also a very good choice for making wine. It is a satisfactory red wine type in the hearts of many bartenders. It has many advantages, resulting in a very good development prospect.

Kiwi Tree Care FAQs

Kiwi tree zone

Kiwi tree fruit not only contains rich nutrition, but also has a pleasant shape. All these external conditions have brought rich economic value to kiwi tree, so Kiwi tree has also become the preferred project for planting. When planting Kiwi tree, we must choose to build gardens in places with convenient transportation, pay attention to the fertility and acidity of the soil, and we should choose to plant it in sandy loam with good drainage and exhaust. However, when planting Kiwi tree, one link can not be ignored is the construction of Kiwi tree zone.
As Kiwi tree is very sensitive to temperature and humidity, it must be noted that during the planting period, the annual average temperature can only be maintained between 11 ℃ and 17 ℃. Therefore, the planting time must not be in summer. Generally, the planting time is the most appropriate from February to march in winter. When planting Kiwi tree, we must dig out a planting ditch with a depth of 60-80cm and a width of about 90-100cm. And the plant row spacing of six meters multiplied by about four meters should be used to maintain a constant distance. Generally, about 110 Kiwi trees are planted in an area of 660 square meters.

Kiwi bush or tree

Kiwi tree needs water but is afraid of waterlogging. Therefore, the requirements for soil moisture and air humidity are relatively strict, which determines that kiwi tree is most suitable for cultivation in areas with abundant rainfall, uniform distribution and high air temperature. The drought resistance of Kiwi tree is worse than that of ordinary fruit trees. Kiwi tree has relatively dense leaf shape, large transpiration and large demand for water. Insufficient water will easily cause Kiwi tree branches to grow slowly, leaves to sag and become smaller, and leaf edges to wither. During drought, the leaves begin to dry up. At this time, it is necessary to timely irrigate or spray water. Especially during the seedling period of Kiwi tree, its root system has not fully expanded, so it is more necessary to supplement sufficient water.
