Recently, many farmers called me and asked me: rice planthoppers are very heavy, rice leaves are rolled into barrels, rice spikes suddenly break, and so on. In response to these problems, I would like to talk about how to do a good job in the post-production management of rice: 1. The prevention and treatment of late-maturing middle rice and late rice planthoppers cannot be taken lightly. We can use 1.5% Chuanzhusu or 0.3% matrine to add imidacloprid or thiazinate copper. If the paddy fields are dry, we can use dichlorvos to disperse it. 2. Rice cannot be water-deficient during the grain-filling period. If the water is deficient, the leaves will lose water and roll drums, and it will also cause rice to be full and empty. Therefore, in the rice filling stage, water shortage, dryness, wetness and wetness are the main factors. 3. Foliar potassium fertilizer or foliar calcium fertilizer or foliar silicon fertilizer should be added to prevent pests and diseases to ensure that the grains are full.
