Before transplanting, we must scientifically apply a "send marriage fat." One is that seedlings that are not robust enough to have a defertilizer phenomenon, after 4:00 pm, apply 3-5 kg ​​of urea and 0.5-1 kg of potassium dihydrogen phosphate evenly per acre, and then immediately wash the seedlings to prevent Produce fertilizer damage; Second, the seedlings are strong, grow strong, the leaf color does not detoxify the normal seedlings, 100 grams of potassium dihydrogen phosphate per acre, 60 kg of water, spray once.
3. Disease prevention and control
To achieve high quality and high yield of rice, it is necessary to cultivate disease-free and robust plants. Therefore, before the seedlings are transplanted, they should be sprayed once. Use 40% "sulfurazole" 150 grams per acre, watered 50-60 kilograms, spray once, have a good effect on the prevention and treatment of rice seedlings.
4. Do a good job of weeding
