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 in early July to mitigate the effects of high-temperature and low-lying drought on grain filling in rice from late July to early August. For the plots where regenerative rice is stored, it is necessary to maintain a 3-4 cm layer of water in the field, which will facilitate the germination and survival of regenerated shoots and lay a foundation for the high yield of ratooning rice.

According to the growing application of panicle fertilizer According to the current situation of large-scale paddy rice, it is recommended that after replanting in the jointing stage (in early July), mu application of urea 5-8 kg, potassium fertilizer 8-10 kg, promote young panicle differentiation and ear formation. 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 is 7-10 days after heading, it can be applied to 15-20 kg of urea and 5-10 kg of potassium fertilizer.

Comprehensive prevention and control of pests and diseases affected by this year's special persistent rainy and widowous adverse weather impact, we must attach great importance to the occurrence and prevention and control of rice pests in the middle and later stages. It is recommended that in the first half of July, the prevention and treatment of Sichuang and panicle blast should be emphasized. In the middle and late July, we will focus on the control of sheath blight, rice leaf roller, and rice planthopper. In early July, spraying 25% aviremectin 120g/ha +40% Jinggangella halophilus 600g/ha, respectively, to effectively control rice stem borer, rice leaf roller and rice sheath blight The hazards. In the rice heading and flowering stage, with 10% imidacloprid WP 20-30 g / mu watered 30-40 kg uniform spray, can effectively control rice planthoppers and other pests.
