Yardlong bean is the most common summer to eat vegetables, tender bean meat fat, fried taste crisp and tender. How to care for Yardlong bean? Let's look together.
New leaf shrinkage in Yardlong beans can be caused by pests and diseases such as rust, virus and red spider. When we care for Yardlong bean, if the leaves turn yellow and curl up, it may also be caused by improper curing. During curing, too much light, too high concentration of herbicide or fertilizer will make the leaves of Yardlong bean curl up, and the curing method needs to be adjusted in the later stage. The following are Yardlong bean care for leaves curly.
During the growth of Yardlong beans, the leaves of Yardlong beans will curl up, become dry or shrivel after being invaded by pests and diseases. The common diseases of Yardlong beans are rust and virus disease, and the insect pest is red spider, which will endanger the new leaves of Yardlong beans, making them curl up or shrivel up. When we care for Yardlong beans, if it is caused by diseases and insect pests, the diseased branches and insect leaves of Yardlong beans should be cut off and burned to cut off the source of infection.
After pruning the leaves of diseased branches, Yardlong beans can be treated with a related agent for control. Yardlong beans can be sprayed with carbendazim or methyltopazine if they have rust or viral disease. When we care for Yardlong beans, if Yardlong beans are affected by the red spider, you can spray the okapi forest or oxidized methyl Fruit agent, about 7 days spray 1 times, continuous spray 3 ~ 4 times can be.
During the growth of Yardlong bean, the leaves of Yardlong bean appeared the phenomenon of crouching, which might be caused by too strong light. Yardlong beans experienced a long period of rainy weather, and then exposed to the sun, under the stimulation of light, Yardlong beans did not grow well, resulting in curled leaves. When we care for Yardlong beans, it needs to be shaded and watered appropriately to replenish water, which is conducive to the recovery of Yardlong bean.
In the early growth stage of Yardlong bean, excessive use of herbicide or fertilizer will cause drug damage or fertilizer damage, which will lead to leaf crinkling. If it is caused by pesticide or fertilizer, it is necessary to water Yardlong bean appropriately to dilute the concentration of pesticide or fertilizer so that it can recover in the later stage. For later curing, the herbicide or fertilizer should be used reasonably to avoid affecting the growth of Yardlong beans.
The failure of Yardlong beans bearing fruits is related to water, fertilizer and temperature. In case of insufficient water, Yardlong beans need to be watered appropriately to replenish water. If the nutrient is insufficient, it is necessary to give it proper amount of fertilizer, so that it can grow normally. If the temperature is not appropriate, the need to adjust the temperature, to increase the temperature, in the summer to do a good job of cooling. The following are details of Yardlong beans care for not bearing fruit.
Yardlong bean is a vegetable crop, during the growth period, only flowers but not fruit may be due to insufficient water. Yardlong beans require adequate air and moist soil during flowering and fruiting. If the air or soil is dry, the fruit growth will be affected. When we care for Yardlong bean, if it is caused by insufficient water, it is necessary to water Yardlong beans in time to replenish water.
Yardlong beans lack nutrients for a long time before the fruit stage. In the case of insufficient nutrients, fruitless phenomena will appear. When we care for Yardlong bean, if it is caused by insufficient nutrients, it is necessary to fertilize Yardlong bean in time to supplement its nutrients. Before the fruit stage of Yardlong bean, thin fertilizer should be applied frequently, and phosphorus and potassium fertilizer is the main fertilizer, which can promote the growth of fruit and the later results of Yardlong bean.
Yardlong beans are temperature-loving and suitable for growing in a warm and ventilated climate with a high requirement for temperature. The suitable temperature for Yardlong beans is between 25 and 28 degrees. If the temperature is below 15 degrees, Yardlong beans will not grow well and will not easily bear fruit. When we care for Yardlong bean, if the temperature of the growing environment of Yardlong beans is not appropriate, the temperature needs to be adjusted to increase the temperature.
Yardlong beans are temperature-loving and grow in warm, cool, ventilated and well-lit environments. During maintenance, reasonable maintenance should be carried out according to its growth habits. Yardlong beans are drought-tolerant and water-resistant, and require proper watering during growth. When we care for Yardlong bean, appropriate fertilization should be applied during the growth period to avoid excessive fertilization and damage to the root system of Yardlong beans.
