Miao Shi Fertilizer Improves Rice Yield
The increase in rice production and the scientific application of fertilizer are critical. Fertilization techniques to increase rice yield have the following: First, the application of organic fertilizer: organic fertilizer is mainly used as the base fertilizer, generally 30-60 tons of fertilized mature soil, or 30-40 kg of cake fertilizer, 40-50 tons of human and animal manure can be applied before the ploughing. Second, the control of nitrogen fertilizer: excessive application of nitrogen fertilizer will not only increase the number of ineffective tillers, love green, lodging, increased pests and diseases, but also lead to more empty grains, decreased seed setting rate, affecting rice yield. Nitrogen fertilizer is mainly used as top dressing. Generally, 6-7 kg of urea is applied to the mu after transplanting rice. The second time is 13-5 days after the transplanting, and 4-5 kg ​​of urea is applied in combination with the cultivated field to promote the strong growth. In the medium term, it is necessary to pay attention to water control and fertilizer control. Only for the second and third types of seedlings with poor growth, some balanced fertilizers should be applied as appropriate, and in the later stage, the seedlings should be supplemented with 3-4 kg of grain fertilizer. Third, pay attention to the application of phosphorus and potassium fertilizer: phosphate fertilizer is suitable for base fertilizer, and potassium fertilizer is better for topdressing. Generally, 20 kg of phosphate fertilizer is applied per acre in a field with sufficient organic fertilizer. As a potash for potash fertilizer, 3.5-5 kg ​​of potassium chloride can be applied per mu. Spraying potassium dihydrogen phosphate in the late stage of rice can promote the filling and firming. Generally, it is sprayed once in the late stage of heading and flowering, and 150 grams of potassium dihydrogen phosphate per acre, and sprayed 50-60 kilograms of water in the evening. 4. Adding micro- fertilizer: trace elements such as zinc, manganese and boron can improve the supply of oxygen in rice roots, enhance the resistance of rice plants, improve the disease resistance of plants, promote the development of roots in the later period, extend the functional period of leaves, and prevent Premature aging; can accelerate the development of flowers, increase the number of flowers, promote the germination of flower granules, and help to increase the rate of rice emergence; it can also promote the large number of spikes, increase the seed setting rate and the grain filling degree, thereby increasing rice yield. According to the test, in the case of the same cultivation and management measures, the application of trace element fertilizer can increase the yield by 40-50 kg per mu, but the production cost per mu is increased by about 2 yuan. Rice is applied with trace elements such as zinc, manganese and boron, and it is generally preferred to spray twice. The first time in the peak period, the second time in the completion of the young spike differentiation. The application rate of zinc, manganese and boron fertilizer is 100-125 grams per acre. The concentration of flushing water is: one thousandth of zinc; the manganese and boron are each five ten thousandths, and the leaves are sprayed on cloudy or sunny afternoons.
