How to avoid high temperature affecting the fruiting of rice? Please introduce the methods to avoid the effect of high temperature on the fruiting of rice, and sow seeds at the right time to avoid the hot temperature. The best heading and flowering date of mid-season rice was arranged in mid-August to effectively avoid the frequent high temperature and summer drought weather from late July to early August. Reasonable selection and application of varieties with strong resistance to high temperature, adjust rice topdressing in the later stage, and increase the ratio of phosphorus and potassium in fertilization. When rice is in a high temperature sensitive period such as heading and flowering, such as heat damage may be caused in high temperature weather above 35 ℃, 3% calcium superphosphate or 0.2% potassium dihydrogen phosphate solution can be sprayed outside the roots in the field to increase the resistance of rice plants to high temperature and reduce high temperature injury. If high temperature has been encountered, then strengthen the late management of the affected fields, first of all, adhere to shallow water moist irrigation. To prevent autumn drought from further aggravating the disaster, do not cut off water too early in the later stage, it is appropriate to cut off water 7-10 days before harvest, and then strengthen the prevention and control of diseases and insect pests. In addition, ratooning rice can also be stored. According to the different degree of disaster, it is an effective remedial measure to store ratoon rice according to local conditions.
