Strengthen field management after rice planting

After rice transplanting, the field management should be strengthened in time to promote the early development of rice, and the following technical measures should be implemented: to strengthen the management of large rice seedlings in the field, and the irrigation method of living plants in deep water and tillering in shallow water should be adopted after transplanting to ensure that the seedlings grow early and tiller early. The direct seeding field should be irrigated with horse race water in time after sowing to ensure early emergence and early completion of seedlings. at the same time, it is necessary to clean and match the field ditch system so that it can be irrigated and drained, and to establish a shallow water layer at the stage of 2 leaves and 1 heart to promote early tillering.

Early application of tillering fertilizer after rice returning to green and living plants, timely application of tiller-promoting fertilizer, generally 5kg urea per mu. At 7-10 days after the first topdressing, according to the occurrence of tillers in the field and the change of leaf color of seedlings, appropriate amount of balanced fertilizer or strong tiller fertilizer was applied, and urea was used for 3-4 kg per mu. For the fields with insufficient basic tiller seedlings and mechanical insertion and direct seeding, the tiller fertilizer should be increased many times.

To control weeds in time, 5-7 days after transplanting, herbicides such as butyl benzyl compound were selected to control weeds in the field, and the shallow water layer was kept for 5-7 days after application.

Strengthening the prevention and control of diseases and insect pests has a large number of gray planthopper every year, the virus-carrying rate is high, rice stripe blight has a pandemic trend, and the planting area of susceptible varieties such as Wuyujing 3 and Wuyunjing 8 has increased, so in addition to transplanting with medicine, the first drug should be used immediately 3-5 days after rice planting, and again every 4-7 days. Japonica rice was used continuously for 3 times and hybrid rice for 2 times.

To promote seedling transformation due to adverse factors such as improper fertilizer and water management or abnormal weather, it is necessary to spray corresponding growth regulators in time to promote seedling transformation.
