Rice fields do a good job of moisture management

At present, rice has entered the jointing stage in most parts of the country. It is recommended to drain the fields in time or let the rice fields dry naturally, so that the roots of rice can be prevented from lodging and lodging, and the pests and diseases in the middle and later stages can be reduced. For non-water-sourced rice fields, a certain water layer should be stored to relieve the impact of high temperature and drought on the grain filling of rice from late July to early August. For the plots where regenerative rice is stored, it is necessary to maintain a 3 to 4 cm water layer in the field, which will facilitate the germination and survival of regenerated shoots and lay a foundation for the high yield of ratooning rice.

Apply panicle fertilizer according to growth. According to the current situation of large areas of rice, it is recommended that after replanting in the jointing stage, the urea will be applied with 5-8 kg of urea and 8-8 kg of potassium, which will promote the differentiation of young panicles and the formation of large spikes. For the plots where regenerative rice is stored, it is necessary to adequately apply “granule bud fertilizer” in a timely manner. After the head rice has 7 to 10 days after heading, it can apply 15-20 kg of urea and 5-10 kg of potash. Comprehensive prevention and control of pests. Affected by this year’s unfavorable climate impact of continuous rainy weather, we must pay great attention to the occurrence and prevention of pests and diseases in rice in the middle and later stages. It is recommended to focus on the control of sheath blight, rice leaf roller, and rice planthopper in mid-to-late July. Spraying with 25% aviremectin 120g/ha + 40% Jinggang bacillus 600g/ha can be effective. Prevention and control of rice borer borer, rice leaf roller and rice sheath blight hazards. In rice heading and flowering stage, with 10% imidacloprid wettable powder 20-30g/mu water 30-40 kg evenly spray, can effectively control rice planthopper and other pests.
