How should summer soybean be managed during the flowering and pod-setting stage? Please provide guidance
During the flowering and pod-setting stage, soybean growth enters a vigorous period, and vegetative growth gradually reaches its peak; this is the period when soybean needs the most fertilizer and water in its entire life cycle. Sufficient fertilizer and water, strong light, and adequate carbon dioxide help promote soybean flowering and pod setting. The level of soybean yield depends on the number of pods and seeds per plant, so in the production management process, soybean plants are required to have lush leaves, deep roots, and strong stems, so as to achieve the goal of many pods and many seeds for a high yield.
Drought during the flowering and pod-setting stage greatly affects the number of pods and seeds of soybean, so irrigation must be carried out in time, and drainage should also be attended to on rainy days. At the same time, protection measures should be determined according to the plant's growth vigor and appearance. For those growing too vigorously with a tendency to spindly growth, deep intertillage or spraying a growth retardant can be used to control excessive growth. If the plants are weak, fertilizer should be applied in combination with intertillage and watering, preferably a compound fertilizer, at 5-10 kg per mu. In July and August, soybean is susceptible to damage by pests. The bridge worm and the soybean worm are pests that occur frequently and can be devastating; they cause more severe damage from late July to early August. Pyrethroid pesticides can be used to control the bridge worm and the soybean worm. Controlling the soybean stem black fly and the soybean stem fly, also two soybean pests worthy of attention, can likewise be done with phoxim or pyrethroid pesticides.
