How to manage summer soybean in the middle and later stage? Please introduce the flowering and podding period, when the growth of soybean enters a vigorous period, and the growth of nutrients gradually reaches its peak; it is the period when the soybean needs the most fertilizer and water in its life, and sufficient fertilizer and water, strong light and enough carbon dioxide are conducive to promoting soybean flowering and fruiting. The yield of soybean depends on the number of pods of soybean, so in the process of production management, soybean plants are required to have luxuriant leaves, deep roots and strong stems in order to achieve the goal of obtaining high yield with multiple pods. Drought at flowering and pod stage has a great influence on the number of pods of soybean, so it must be irrigated in time, and waterlogging should be paid attention to on rainy days. At the same time, protective measures should be determined according to the growth and appearance of the plant. If the plant is too prosperous, it can be controlled by deep ploughing or spraying. If the plant is weak, it should be combined with ploughing and watering, and it is best to apply compound fertilizer, 5kg / mu. 7-8 portions of soybean are easily harmed by pests. Bridge insects and bean insects are frequent and destructive pests, which are more harmful from late July to early August. Pyrethroids pesticides can be used to control bridge insects and bean worms. Soybean stalk black miner and bean stalk fly are also two noteworthy soybean pests, and phoxim or pyrethroid pesticides can also be used to control soybean pests. The main goal of the grain maturity stage is to protect leaves, roots, and increase the number of pods. The grain filling stage, especially at the early stage, is sensitive to water, and at this time it gradually enters the dry season, so it is necessary to water some plots in case of drought, and foliar fertilization should be carried out on some plots. Spray 1%-2% urea or 2%-3% superphosphate solution, the time should be after 3 pm. The main pests in grain mature stage are heart borer and cotton bollworm, which can be controlled by phoxim, dioxin and other insecticides.
