How to manage the flowering of summer soybean?
How to manage the flowering of summer soybean? Please introduce the management of summer soybean flowering with reference to the following methods: 1. Mid-tillage: in the late flowering period of summer soybean and entering the period of vegetative growth and reproductive growth at the same time, during this period, the temperature is high, the light is strong, and the plant growth rate is fast. generally, the average plant height increases by 2-3 cm per day, and it is easy to grow and lodge and reduce yield in high fertilizer and water plots. Therefore, summer soybean should be ploughed once before flowering and ridge sealing, so as to maintain good soil permeability, facilitate root development and increase lateral roots. 2. Watering: flowering is the key period of water demand for summer soybean, and drought in the early stage of flowering will cause plant falling flowers. At the end of flowering, the vegetative growth of the plant reached the peak, the metabolism was exuberant and the water consumption was large. At this time, if the soil water content decreased, it would easily lead to the physiological water shortage of the plant and cause a large number of flowers and pods to fall off. 3. Topdressing: 5 kg of available nitrogen fertilizer ammonium nitrate should be applied at the early flowering stage, 150-200 g of potassium dihydrogen phosphate per mu and 50 kg of water should be sprayed on the leaf surface to promote plant flowering and pod formation and improve quality. 4. Spraying: the resistance of summer soybean to external adverse environment is very weak at flowering stage. If chemical agents are sprayed at this time, it is easy to make flower buds fall off and blighted grains increase. If the occurrence of diseases and insect pests in the flowering period of summer beans must be controlled with drugs, it is best to choose after 4: 00 p.m., and strictly control the dosage and concentration.
