After zinc deficiency in rice, the plants are short, no sputum or less tillering, stunted, and the growth is not prosperous, and it is easy to "sit." The maturity period is delayed, resulting in a significant drop in production. There are many ways to apply zinc in rice. In practice, the appropriate method can be selected according to the specific conditions.
1. The bottom of the field is applied with 1000 grams of zinc as the base fertilizer, which can greatly improve the quality of rice and increase the unit yield by 8.8%. Generally, the application of 1000-1500 grams per mu, the application of 1000-1200 grams of sandy soil, and the application of 800-1000 grams of clay soil. When the base fertilizer is applied once, the 2-3 crops will not be deficient in zinc.
2. Phosphorus and zinc combined application Phosphorus and zinc fertilizer combined application can promote the absorption capacity of rice, improve the resistance of seedlings, and prevent the occurrence of dead seedlings caused by low temperature in early rice fields. Generally, after the rice is inserted for 7-8 days, the application of zinc and phosphorus (1:10 ratio) mixed fertilizer is about 18 kg, which can increase the yield, enhance the stress resistance and improve the rice quality.
3. Zinc application in the seedbed 40 grams of zinc sulfate per square meter of seedbed is sprayed one day before transplanting, sprayed with a big eye pot, and then washed with water.
4, 蘸秧 root fertilizer When rice seedlings are transplanted, 500 grams of zinc sulphate is used in the field, and 10-20 times of organic fertilizer is added.
5, Daejeon noodle When the rice is transplanted, the soil is planted with 1000 g of zinc sulfate in the field.
6, when the seedlings are topdressing, the use of 1000-1200 grams of mu in the rice transplanted seedlings after spraying.
7, foliar spray fertilizer acres with 0.2% -0.3% zinc sulfate solution 50-60 kg foliar spray 2 times, 4-6 days apart.
