Soybean Flowering Period Management
First, cultivator: Soybeans will enter the period of vegetative growth and reproductive growth after flowering. At this time, the temperature is high, the light is strong, and the plant growth rate is fast. In the high-fertilizer land, it is easy to form an “extreme type†lodging and production reduction. Therefore, it is necessary to cultivate the soybeans before flowering and mulching to maintain good permeability of the soil, facilitate the development of the root system, increase the lateral roots, and control and promote the adaptability of the individual development and population structure to achieve robust development of the plants, drought resistance, and resistance to pods. Resistance to fall, increase production purposes.
II. Drainage and Irrigation: The flowering period is the key period for soybean water requirement. If the soil moisture exceeds 80% of the field water capacity, the growth and development of the plant will be affected. Therefore, after the heavy rain, the water in the field should be promptly discharged to reduce the soil and air. Humidity promotes normal plant growth. At the end of flowering, the growth of vegetative matter reaches a peak, and the metabolism is strong. At this time, if the soil water content is reduced, it will cause a large number of scapes to fall off. Therefore, it is necessary to water in time according to the lack of soil.
Third, topdressing: to the late growth stage if there are fewer scapes, shedding, leaf color, plant thin, etc., that is, the phenomenon of deferment, fertilizer should be timely, add soil nutrients.
IV. Spraying: Soybeans have weak resistance to the external environment during the flowering period. Spraying chemical agents at this time will kill pollen, damage the stigma, cause the buds to fall off, and increase the size of pods, which usually leads to a 10% to 15% reduction in production. If pests and diseases occur during the flowering period and it is necessary to use drugs, it is best to choose after 4 pm, and strictly control the dosage and concentration.
