During the flowering and podding stage of summer soybeans, the main goal is to achieve more flowers, earlier flowers, and uniform flowering, and to prevent flower and pod drop while increasing flowers and pods. This is the central task of management during this period. Management should be based on observing the seedlings, combining preservation and control. For high-yield fields, control should be the main approach, avoiding early canopy closure, and it is best to reach maximum leaf area at the end of flowering. The specific measures are: continue hoeing weeds before canopy closure, and apply water and fertilizer as appropriate based on seedling condition. For weak seedlings, apply topdressing at the early flowering stage; for strong seedlings, do not apply topdressing to prevent excessive vegetative growth. Applying phosphorus fertilizer during the flowering and podding stage has an obvious effect, generally by foliar spraying, such as potassium dihydrogen phosphate, Doubaobao, etc. At this time, soybean leaf area reaches its maximum, water consumption increases, and water demand also reaches its peak. When the leaf color turns dark green and the leaves wilt at noon, water should be applied promptly; otherwise, flowers and pods will drop. For high-yield fields, to prevent lodging and excessive growth, chlormequat can be sprayed to prevent lodging.
