What are the latest control measures for summer dormancy in yardlong beans
When planting yardlong beans, if summer dormancy occurs in the plants, the yardlong bean plants will weaken in growth, the leaves will turn yellow, the number of flowers will decrease, and flower and pod drop will occur, so the yield of yardlong beans will be seriously affected and decline. This is very unfavorable to the planting benefits of farmers, so if summer dormancy occurs in yardlong beans, what should be done? Below, the editor brings you the control measures for summer dormancy in yardlong beans, let's take a look together!
1. Maintain the environment
Summer dormancy generally occurs in summer. In summer, because high-temperature and high-humidity environments are prone to occur, yardlong beans are also prone to excessive vegetative growth. If drought is added on top of this, then pollination of yardlong beans will be inhibited, causing summer dormancy in yardlong beans. Therefore, if we want to prevent and control summer dormancy, then first of all we must pay attention to creating a suitable growing environment for yardlong beans. For example, control the planting density well, strengthen management of excessive seedling growth, and do a good job in hardening seedlings. Avoid excessive growth of seedlings and keep every seedling with sufficient growing space.
2. Strengthen ventilation
If yardlong beans are grown in a greenhouse, then we also need to pay attention to doing a good job in ventilation and maintain a suitable greenhouse temperature. When the rainy season comes, attention should be paid to timely drainage. Prevent excessive water accumulation in the soil from affecting the growth of the yardlong bean roots, causing root rot and other phenomena, thereby triggering summer dormancy. Only by maintaining a suitable environment can the phenomenon of summer dormancy in yardlong beans be reduced in summer. If yardlong beans grow too vigorously, then they should be controlled in time, and methods such as hoeing and loosening the soil can be used to control the vigorous growth trend of yardlong beans.
3. Reasonable fertilization
Unreasonable fertilization is one of the main causes of summer dormancy in yardlong beans. When we plant yardlong beans, we should have a reasonable fertilization plan. When applying base fertilizer, too much nitrogen fertilizer should not be added, to prevent excessive nitrogen fertilizer from causing excessive growth of yardlong bean seedlings and affecting the number of flowers and pods of yardlong beans. And when fertilizing, the amount of fertilizer should be controlled according to soil fertility, and it is best to carry out soil testing and formula fertilization. Under normal circumstances, about 3000kg of decomposed farmyard manure should be applied per mu as base fertilizer, together with an appropriate amount of superphosphate, potassium sulfate, etc. Then in the later stage, the proportion of phosphorus and potassium fertilizers should be appropriately increased, and nitrogen fertilizer application should be reduced.
4. Pruning and topping
In addition to the above, we should also pay attention to doing a good job in pruning and topping the yardlong bean plants. Control the pod-setting position of yardlong beans well to prevent the pods from setting too high, which would lead to a decline in yield. The side buds sprouting from the bottom of the yardlong bean plants should be removed in time, and then the side buds about 50 cm upward on the main branch of the yardlong bean plant should also not be retained. Improve the ventilation at the base of the plants. When the yardlong bean plants begin to cover the entire trellis, topping should be carried out. Leaf buds sprouting from the leaf axils should also be removed in time to avoid consuming too much nutrition, ensure normal growth of yardlong beans, and prevent the occurrence of summer dormancy.
The above is a brief introduction to the control measures for summer dormancy in yardlong beans. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
