In August, the late rice in Hubei Province will be in the stage of greening ~ tillering - young panicle differentiation, the middle rice is in the heading and flowering stage, and the cotton is in the flowering and boll stage. The meteorological department expects that the average temperature in northern Hubei in August is slightly lower than that in normal years, and slightly higher in the south, including northwestern Hubei and southwestern Hubei, 25.5 to 26.5 °C northeast, Jianghan Plain, 27.0 to 28.5 °C, southeastern Hubei, 28.5 to 29.5 °C; precipitation E It is 120-150 mm in the northwest, northeastern Hubei and Jianghan plains, 160-190 mm in the southwest of Hubei, and 110-140 mm in the southeast of Hubei.

The cold air and precipitation process are generally 1 to 2 days, 11 to 14 days, 19 to 22 days, and 30 to 31 days.
   Agrochemical experts combined with August climate prediction and crop development process, it is recommended:

2. The high temperature will continue in the first half of August. During the high temperature period, deep water irrigation (below the ear) should be carried out in the high temperature period, and the night row should be irrigated to reduce the temperature of the ear and reduce the high temperature hazard.
3. Pay attention to the prevention and control of rice pests and diseases, and focus on the prevention and control of second-generation sputum, mites, sheath blight, rice blast and "two-shift" pests.
4, strengthen the post-mortem cotton field management, disease prevention and pest control, timely topdressing, topping combined with topping on the poor light transmission of the cotton field in time to destroy the lower old leaves, go to the empty branches, pick the side heart, wipe the buds, concentrate nutrition attack peach More knotted bells, less shedding, less rotten peaches.
