1. Choose high-yield, high-quality, disease-resistant varieties. Such as Chu Yu 27, 28, Yun Yu You 7 and so on.
2. Cultivate more and more people. The key is to deduct the seeding and sowing, the amount of each acre is less than 30 kilograms, and the perforated film is used for breeding.
3. Sowing and transplanting at the right time. Try to do early planting early, the sowing period should be determined according to the transplanting period, generally planted on March 5-10, transplanted from May 1 to 10, suitable for 45-50 days, and 5-6 leaves.
4. Reasonable close planting. It is planted in wide and narrow rows, with specifications of (8+4) x 3 square inches, density of 3 to 33,000 bushes, 2-3 seedlings per cluster, and 7 to 100,000 seedlings per acre.
5. Add organic fertilizer, NPK combination. 190-2000 kg of fertilized farmyard manure is used as the base fertilizer, 50 kg of special compound fertilizer for rice and 2 kg of zinc sulfate for intermediate layer fertilizer, 60 kg of ammonium bicarbonate for branching fertilizer, 15 kg of urea and 10 kg of potassium sulfate for panicle fertilizer.
6, reasonable irrigation. The principle of irrigation is shallow water transplanting, deep-water living, thin water, sputum, deep water, and dry and wet seeds.
7, timely prevention of disease, insects, grass damage. The safe and high-efficiency herbicide, chlorpyrifos, was used to remove the stalks, and the field hair was removed from the field. Use tricyclazole to control rice blast, jinggangmycin or love seedlings to control rice smut. Use insecticidal double to control aphids, and imipenem to control insects such as armyworms and planthoppers.
