What are the management measures for soybean during the flowering and podding stage? A detailed explanation

1. Topdressing with flower-pod fertilizer. Practice has proven that topdressing during the flowering and podding stage has an obvious effect on subsequently increasing flowers and preserving pods, reducing shedding, and raising yield. Fertilization method: at the early flowering stage of soybean (earlier for poor-growing plants, later for vigorously growing plants), apply 5-10 kg of urea per mu. If the soil has strong fertilizer supply capacity and the plants grow robustly, apply less or not at all, so as to avoid causing excessive vegetative growth, which may lead to lodging or increased flower and pod shedding. In combination with nitrogen topdressing at the flowering stage, foliar spraying of phosphorus and potassium fertilizers and trace fertilizers such as boron and molybdenum has an even better yield-increasing effect. 2. Drought resistance

2. Drought resistance and drainage. The flowering and podding stage of soybean is the period of most vigorous vegetative growth and reproductive growth, and also the period when the plant's dry matter accumulates rapidly and the leaf area index expands significantly. If water is insufficient, the plants will show wilting. In addition, the massive formation of pods requires sufficient water. Irrigation during this period can increase yield by 15-30%. The irrigation method is best done by furrow irrigation, with small amounts of water in the furrow until the soil is moist.
