Money tree is a Perennial herbaceous flowers, plant height 50 cm to 80 cm, underground corn on the growth of zemi cycads or fern like pinnate compound leaves, petiole fleshy, with lobules 7 to 10 pairs, lobules elliptical, like pairs of neatly arranged copper coins. Money tree is reddish brown.
Money tree is a deciduous shrub or small tree, 3-6 meters high, rare up to 10 meters; Young staffs are grayish green, glabrous, old branches dark gray; Bud of Money tree is terete, 8--10 mm long, bud scales broadly lanceolate, about 5 mm long, 1.5 mm wide, reddish, apex with a small tip, margin ciliate.
Leaves are often clustered at apex, papery, oblong to oblong-elliptic, 3 -- 4(--5) cm long, 2 -- 2.5 cm wide, apically obtuse, with a short convex acuminate, base broadly cuneate or cuneate, margin obtuse serrate, glabrous on both sides, midvein concave under surface, with lateral veins not obvious on surface, obvious on back, four veins visible on back; Petiole of Money tree is stout, 0.8-1(--15) mm long, slotted, glabrous.
The flowers of Money tree are mostly composed of umbellate racemes; Flowers are very slender, 2.5-4 cm long, glabrous; Flowers are drooping; Calyx of Money tree is 5-lobed, lobes triangular, ca. 2.5 mm, ciliate; Corolla is broadly campanulate, 1 cm long and 1 cm wide, fleshy red, mouth 5-lobed; Money tree has 10 stamens, inserted at base of corolla, filaments 4.5 mm long, dilated below center, puberulent, anthers 2-lobed, 1.5 mm long, awns ca. 1 mm; Ovary of Money tree is globose, longitudinally striated, sparsely white with short hairs, style ca. 5.5 mm, sparsely puberulent.
Money tree capsule ovoid, 6-9(--8) mm in diameter, loculicidal dehiscence into 5 Fruit petals, valves ca. 6 mm long and 3.2 mm wide, with a micro longitudinal groove in the middle of the valves. Seeds of Money tree ca. is 6 mm, slightly glossy, wrinkled, winged, with many seeds in each cell, the seeds are carried above the central axis.
Originating in: North and Central China.Japan, Korea also have distribution. Now Hunan Koelreuteria base, Jiangsu Koelreuteria base, Zhejiang Koelreuteria base are a large number of artificial cultivation.
Money tree is a positive tree species, like light, slightly tolerant to half shade; Money tree is cold resistant (Huangshan Luan is poor); Money tree is tolerant to drought and barren, also resistant to low wet, saline-alkali land and short-term flood damage. Money tree has deep roots, strong roots, strong tillering ability, medium growth rate, slow when young, gradually faster later, wide adaptability, not strict requirements on soil, can grow in slightly acid and alkaline soil, prefer to grow in calcareous soil. Money tree has strong wind resistance, can resist the low temperature of minus 25℃, to dust, sulfur dioxide and ozone have a strong resistance. Money tree has less pests and diseases, easy cultivation and management.
Money tree can grow well in bright or dark places. In summer, high air humidity should be maintained and shading should be paid attention to. In winter, a relatively dry environment should be maintained but bright light is needed. Cultivation substrate with fertile loose, rich in organic matter, good air permeability, water and fertilizer retention ability is strong, but no water retention of the best micro-acid soil, the growth of compound fertilizer once a month.
Temperature: The suitable temperature for Money tree growth is 20-32 ℃. Whether pot or ground, Money tree requires a small change in annual average temperature. It is best to maintain a cabin temperature above 10℃ in winter, and if the room temperature is lower than 5℃, it is easy to cause cold damage to plants and seriously endanger their survival. At the end of autumn and early winter, when the temperature drops below 8℃, Money tree should be moved to the room with sufficient light in time. During the whole wintering period, the temperature should be maintained between 8℃ ~ 10℃, so that it is relatively safe and reliable.
Illumination: Money tree likes light and has strong resistance to negative, and should create a better sunshine but also a certain degree of shade environment. It avoid direct light, especially should avoid the late spring and early summer long rain after the sun exposure and summer noon around 5~6 hours without blocking the strong light baking, otherwise it is easy to lead to new smoke young leaves were burned. Supplemental light should be given to potted Money tree that are moved to the shed during the winter. Basin soil moisture to keep dry, plants can maintain a long - year disease - free.
Moisture: in order to maintain a good pot Money tree, we should try to create a moist and dry environment for it. Because Money tree has stronger drought tolerance, should be in order to maintain basin soil micro wet partial dry had better, but occasionally irrigate water fertilizer excessively, also do not cause root rot root. In winter, we should pay attention to spray water on the leaf surface and the surrounding environment, so that the relative air humidity can reach more than 50%. After the Mid-Autumn Festival to reduce watering, or watering, in order to help the new Money tree leaves of the safe winter. In addition, in winter, special attention should be paid to the basin so the soil can not be too wet. It is better to be dry, otherwise under low temperature conditions, the basin soil is more likely to cause root rot, or even the death of the whole plant.
Soil: Due to the special climatic conditions in the place of origin of M. chinense, Money tree has formed a strong drought resistance, so the basic requirement for cultivation substrate is good permeability. The cultivation substrate is often mixed with a small amount of Garden soil, such as peat, coarse sand or washed coal cinder, and its pH value is adjusted to between 6 and 6.5, showing a slightly acidic state. Because the Money tree tuber is large, the root system is developed, the pinnate compound leaf is longer, the growth season should observe its growth situation in time to decide whether to change the basin to change the soil. Always keep the cultivation substrate permeability is good, in order to create a good root environment of air permeability and water filtration. Plum rain season to check frequently, found inside the basin water phenomenon occurs, to give in time to turn the basin for soil.
Fertilizer: Money tree more like fertilizer, in addition to the cultivation matrix should be added to the right amount of retting made of Craft Fertilizer or multiple slow release compound fertilizer, growth season can be poured 2 ~ 3 times a month 02.% urea plus 0.1% potassium dihydrogen phosphate mixture, can also be poured into a balanced fertilizer 20-10-20 (20-20-20), concentration of 200 ~ 250ppm, combined with calcium nitrate use. After the Mid-Autumn Festival, in order to make Money tree safe for the winter, should stop applying nitrogen fertilizer, continuous toppressing 2 ~ 3 times 0.3% potassium dihydrogen phosphate solution, in order to promote the young leaf axis and new leaf hardening and enrichment. When the temperature drops below 15℃, all forms of topdressing should be stopped to avoid root damage caused by fertilizer under low temperature conditions.
Freezing damage: when the temperature drops below 5℃ in winter, coupled with the moist soil in the basin, it is easy to cause Money tree-like tender leaves to be frozen and cold, and it will cause the tuber to rot seriously, and it is difficult to restore vitality.
Prevention and control methods: greenhouse temperature should be maintained during the winter is not less than 10℃, and keep the basin soil slightly dry.
Burns: on a hot summer, or attendance fine weather after the long rain, or long time indoors first moved to outdoor restorative curing pot planting of Money tree, direct exposure to the sun, it is easy to cause its fat leaf burns, the blade part of its green and white, or the entire leaf burns, late necrosis part black brown.
Brown spot: this disease is more on the Money tree leaf, the disease spot is nearly round, grayish brown to tan, the edge color is slightly darker. The disease is easy to occur under the condition of high temperature, high humidity and poor ventilation.
Prevention and control methods: a small amount of disinfected leaves should be removed and destroyed in time, and 50% carbendazim wettable powder 600 times liquid or 40% chlorothalonil suspension 500 times liquid should be used in the early stage of disease, and the leaves of Money tree should be sprayed every 10 days for 3 to 4 times continuously, with good prevention and control effect.
After the summer, the Money tree will be moved to the semi-overcast environment in time, late spring and early summer long rain early sunny, should be as early as possible to plant a shading basin.
Scale insects: in the poorly ventilated, poor light environment, the leaves of the Money tree are easy to be harmed by scale insects.
Prevention and control methods: can be in the nymphs incubation period, spraying 20% of the dipterin wetter powder 1000 times liquid or fast killing 1000 times liquid, or scale death net 500-800 times liquid, generally continuous spraying 1 ~ 3 times, each interval of 7 ~ 10 days, insecticidal effect is good.
