Embodiment 1

[0011] Embodiment 1: EDDHA-Fe chelated iron 6% former powder 2kg, selenium inorganic compound sodium selenite 0.7kg, phosphate fertilizer 90kg, poultry manure 150kg, peanut seedling 1000kg, cassava leaf 500kg, mixed retting makes selenium-rich base fertilizer, For 1 mu of dosage. Evenly spread and bury in the soil during site preparation; take 1 part of sodium selenite, an inorganic compound containing selenium, and dissolve it in 75 parts of Chinese medicine extracts of Chinese yam, scrophulariaceae, Polygonatum odoratum, Radix Astragali, Polygonatum and Wolfberry with a concentration of 11%. The selenium-enriched foliage fertilizer is made in the middle, and the dosage is 1 time per mu, and it is sprayed on the rice leaf surface at the early stage of rice heading and flowering; it is sprayed once more in the early stage of rice filling as above. If it rains after each spraying, respray once in time. Rice milled from this kind of rice has a selenium content of 250-300 microg...

Embodiment 2

[0012] Embodiment 2: EDDHA-Fe chelated iron 6% former powder 5kg, selenium inorganic compound sodium selenite 1.1kg, phosphate fertilizer 100kg, poultry manure 250kg, peanut seedling 800kg, cassava leaf 700kg, mixed retting makes selenium-rich base fertilizer, For 1 mu of dosage. Evenly cast and bury in the soil during site preparation; take 1 part of selenium-containing inorganic compound and dissolve it in 90 parts of Chinese medicine extracts with a concentration of 14% of Chinese yam, Scrophulariaceae, Polygonatum odoratum, Astragalus membranaceus, Polygonatum and Wolfberry to make rich Selenium foliar fertilizer is used once per mu, and is sprayed on the rice leaf surface at the early stage of rice heading and flowering. At the initial stage of rice filling, spray again according to the above method. If it rains after each spraying, respray once in time. Rice milled from this kind of rice has a selenium content of 260-29 micrograms per kilogram.

Abstract

The invention discloses a formula fertilizer for promoting the growth of rice. Before the seedlings are transplanted, the selenium-rich base fertilizer is applied in the paddy field. The selenium-rich base fertilizer is made by mixing raw powder containing 6% EDDHA-Fe chelated iron, selenium inorganic compound sodium selenite, phosphate fertilizer, poultry manure and green manure. The selenium-enriched foliar fertilizer was sprayed once at the initial stage of heading and flowering of rice and the initial stage of grain filling respectively. The selenium-enriched foliage fertilizer is made by dissolving the selenium-containing inorganic compound sodium selenite in the leachate of traditional Chinese medicine. The invention enables the rice to have multiple opportunities to ingest selenium element from nutrition during the growth and development process, is beneficial to increase the selenium content of the rice, and has the function of health care. This kind of rice can be made into various rice foods, such as rice, rice noodles, cakes, biscuits, etc. It is non-toxic and has no side effects, and can enhance the immunity of the human body.

Description

technical field [0001] The invention belongs to a crop cultivation method, and relates to 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 will reduce the immunity of the human body, affect people's quality of life, and even endanger people's health. To increase people's selenium intake, 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. Therefore, it is necessary to increase the selenium content in food through human behavior. Rice is a staple food that the broad masses of our country like. Improving the selenium content of rice must start from rice cultivation, that is, adding various inorganic selenium to rice nutrition, and relying on the biotransformation process of rice growth to convert it into organic selenium, so a...
