Paddy rice planting rice glutinous rice

In order to increase the economic benefits of growing rice, it is necessary to adopt cultivation techniques that create high-yielding and high-quality rice. We learn Japanese rice indica rice, which is the technique of applying rice bran as organic fertilizer and weeding. After several years of successful experimental research, the following are introduced: Advantages of fertilizing rice bran 1. It can significantly increase yield. The average increase in production in our province from 2002 to 2003 was 17.2%. Large-scale demonstration in 2003 increased production by 12.2%. The main factors for increasing the yield were the results of increasing the spike rate, seed setting rate and 1000-grain weight of rice compared with the control. 2, weeding effect is good. The results of the two-year test showed that the comprehensive control of weeds reached about 90%, and the effect of controlling weeds was 95-97%. 3, considerable economic benefits. Fertilizer, can be less 5 kg of urea per acre, the province 10 yuan, without any herbicide, 10 yuan per mu, province, the production of green rice more than 0.2 yuan per kilogram added value, the efficiency of rice production per acre rice blasting rice planting costs enough. The use of rice bran to increase fertility yields because the rice bran is high in organic matter content, and its crude protein and sugar content are relatively balanced, and it contains high-calorie fat and a lot of vitamins and minerals. The production of secretions in the process of reproduction of microbial decomposition promotes the formation of granule structure. The decomposition of microorganisms after dying releases the accumulated amino Acids and fatty acids in the body for the absorption and utilization of rice in the middle and later stages, promoting the ripening of live stalks and increasing the yield. When rice bran is decomposed on the surface of a paddy field, a large amount of carbon dioxide and low-level organic acids are produced within a week, and a large amount of oxygen is consumed, so that the rice fields are in a reduced state, impeding the germination and growth of the grass seeds and achieving herbicidal action. Rice bran fertilization and grub technology are performed according to the normal paddy cultivation and sparse cultivation techniques. The difference is that the normal fertilization amount, nitrogen fertilizer and urea are reduced, and the general mu is reduced by about 5 kilograms. The other phosphorus and potassium fertilization measures and fertilizer methods are unchanged. . Rice bran is a kind of fine glutinous rice produced by processing rice, with a dosage of 200-250 g/m2, which can add 10-20% of crude glutinous rice or husk crushed. Rice husk contains high silicon content. Shi Lang period is 7-10 days after rice transplanting, when rice just returned to green. Both the chemical fertilizers used for the greening of rice and the blending of the chemical fertilizers were evenly spread on a windless day. Then keep the shallow water layer. As the temperature rises, plutonium can be decomposed, rice husks cover the surface of the soil to facilitate thermal insulation and herbicide, and the silicon component is decomposed later in the decomposition process. Note that there must be no windy days, and after the dew is gone, it is necessary to prevent the promotion from sticking to rice leaves.
