Embodiment 1

[0011] Example 1: EDDHA-Fe chelated iron 6% raw powder 2kg, selenium inorganic compound sodium selenite 0.7kg, phosphate fertilizer 90kg, poultry manure 150kg, peanut seedlings 1000kg, cassava leaves 500kg, mixed and retorted to make selenium-enriched base fertilizer, The amount is 1 mu. During site preparation, it is evenly applied and buried in the soil; take 1 part of selenium-containing inorganic compound sodium selenite dissolved in 75 parts of the same amount of Chinese yam, Scrophulariaceae, Polygonatum odoratum, Astragalus, Polygonatum and Qizi at a concentration of 11%. The selenium-enriched foliar fertilizer is made into selenium-enriched foliar fertilizer, which is applied once per mu, sprayed on the leaf surface of the rice at the early stage of rice heading and blooming; sprayed once more as the method above at the early stage of rice filling. If it rains after each spraying, make up one spray in time. The selenium content of rice milled from this kind of rice is ...

Embodiment 2

[0012] Example 2: EDDHA-Fe chelated iron 6% raw powder 5kg, selenium inorganic compound sodium selenite 1.1kg, phosphate fertilizer 100kg, poultry manure 250kg, peanut seedlings 800kg, cassava leaves 700kg, mixed and retorted to make selenium-enriched base fertilizer, The amount is 1 mu. During site preparation, it is evenly applied and buried in the soil; 1 part of selenium-containing inorganic compound is dissolved in 90 parts of the same amount of Chinese yam, Scrophulariaceae, Polygonatum, Astragalus, Polygonatum and Qizi at a concentration of 14% to make a rich Selenium foliar fertilizer is applied once per mu, sprayed on the rice leaves at the early stage of rice heading and flowering. In the early stage of rice filling, spray again according to the above method. If it rains after each spraying, make up one spray in time. The selenium content of rice milled from this kind of rice is 260-29 μg / kg.

Abstract

The invention discloses a formula fertilizer capable of promoting the growth of paddy rice. Before transplanting seedlings, a selenium enriched base fertilizer is applied to the paddy fields. The selenium enriched base fertilizer is prepared by mixing and composting EDDHA-Fe raw powder with a chelated iron content of 6%, a selenium inorganic compound (sodium selenite), phosphate fertilizer, manures of livestock and cattle, and green manure; and the base fertilizer is evenly sprayed and buried in soil during soil preparation. The selenium enriched foliar fertilizer is sprayed for once in the initial stage of head sprouting and flowering of paddy rice and the initial stage of grouting. The selenium enriched foliar fertilizer is prepared by dissolving a selenium containing inorganic compound (sodium selenite) into traditional Chinese medicine leachate. Through the technical scheme mentioned above, paddy rice can absorb the selenium element for many times during the growth period, the root of paddy rice becomes strong, the number of seedlings is increased, the rice spikes are plump, and the performance on resisting diseases and pests is enhanced.

Description

Technical field [0001] The invention belongs to a crop cultivation method, and is a formula fertilizer for promoting the growth of rice. Background technique [0002] Selenium is one of the trace elements necessary for the human body. Insufficient selenium element will reduce the body's immunity, affect people's quality of life, and even endanger people's health. To increase people's intake of selenium, obtaining selenium from food is a broad and effective way. However, the selenium content in natural food is low, and it is difficult to meet the human body's demand for selenium. Humans must act purposefully to increase the selenium content in food. Rice is a staple food loved by the broad masses of our country. To increase the selenium content of rice, it is necessary to start with rice cultivation, that is, to add various inorganic selenium to rice nutrition, and transform it into organic selenium through the biological transformation process of rice growth, so as to facilitat...
