Recently, fresh soybeans covered with double membranes (mulching film and small sheds) in our province have gradually entered the flowering period. The flowering period is a critical period for the growth of soybeans, and strengthening field management at the flowering stage plays an important role in improving the yield and quality of fresh sorghum. Farmers in this period on the field management of soybean plants to do the following: Remove the small arch film: the current daytime temperature is close to the optimum temperature for soybean growth, remove the small arch film is conducive to the use of soybean plants to fully use the sun, strengthen the photosynthetic Role, to improve plant growth and improve plant resistance. Topdressing flowers and fertilizers: Applying timely fertilizer to soybean plants during the flowering period can not only increase the rate of scabs of the plants, but also help to improve the commercial quality of the fresh oysters and extend the picking period. Generally, 12-15 kilograms of urea can be applied per acre. In the initial stage of flowering, ammonium molybdate solution can also be sprayed to help increase the seed setting rate. Qinggou Canal: Although the flowering period is the period when the water demand of soybeans is the largest, the rainwater in our province gradually increases in April. Under normal circumstances, it can fully meet the demand for water in the flowering period of soybean, and there is no need to prevent drought. On the contrary, it is necessary to do a good job of clearing the ditch and canal to prevent the accumulation of water in the field, so as to avoid causing excessive humidity and affecting the root growth of the plant. Spray insect control: At the beginning of the film removal, soybean plants are tender and susceptible to insect pests such as aphids. Generally, 50% anti-inferior WP 2000 times solution or 20% chlorinated WP 4000-6000 solution may be used in sunny days. Spray control.
