Major measures for rice production management
Early rice: One is to strengthen the prevention and control of weeds in early rice, especially live rice fields. The combination of chemical weeding and manual weeding is used to curb the weeding, and the work of replenishing and replenishing scavengers in live fields is stepped up. The second is to chase early rice in a timely manner. Per acre topdressing urea 5-7 kg, 5 kg of potash fertilizer. The prevention and treatment of sheath blight of early rice use a combination of potash fertilizer and agent (streptococcus) control. The third is the direct broadcast of early rice fields and early planting of early-onset rice fields, focusing on the prevention and control of rice for the first time. Middle rice: First, strengthen the management of fertilizer and water in mid-season, one-season rice paddy fields and seedlings, and cultivate strong and strong ones. Second, high-quality rice, japonica rice and hybrid rice should pay attention to the implementation of pesticide soaking (immersion seedlings) and seedlings 1-3 leaf stage prevention of rice blast disease. The agent is sprayed with 28-40 grams of rice bran, or 20-25 grams of tricyclazole, and 50 kilograms of water per acre. Third, the use of base fertilizers in the production of medium rice and one-season rice in the field should be promoted and promoted through the application of formula fertilization techniques for controlling nitrogen, phosphorus and potassium. Nitrogen: Phosphorus: Potassium (N: P205: K20) is generally 1:0.5:1, and pure nitrogen (N) 12-15 kg is used for the mu; phosphorus (P205) is 6-7 kg; potassium (K20) is 12-15 kg. The fourth is to pay attention to the prevention and control of the rice planting, rice borer of a rice borer and rice thrips.
