Embodiment 1

[0011] Embodiment 1: 0.8kg of selenium-containing inorganic compound, 100kg of phosphate fertilizer, 300kg of poultry and livestock manure, and 800kg of green manure are mixed and retting to make selenium-enriched base fertilizer, which is an amount for 1 mu. Spread and bury evenly in the soil during site preparation; take 1 part of selenium-containing inorganic compound and dissolve it in 80 parts of traditional Chinese medicine leaching solution with a concentration of 10% to make selenium-enriched foliage fertilizer, and use it once per mu. Spray on the rice leaf surface; spray again as above in the early stage of rice filling. If it rains after each spraying, respray once in time. Rice milled from this kind of rice has a selenium content of 250-300 micrograms per kilogram.

Embodiment 2

[0012] Embodiment 2: 1.1kg of selenium-containing inorganic compound, 100kg of phosphate fertilizer, 400kg of poultry and livestock manure, and 900kg of green manure are mixed and retting to make selenium-enriched base fertilizer, which is the dosage for 1 mu. Evenly spread and bury in the soil during site preparation; take 1 part of selenium-containing inorganic compound and dissolve it in 90 parts of traditional Chinese medicine leaching solution with a concentration of 14% to make selenium-rich foliar fertilizer, and use it once per mu. Spray on rice leaves. In the early 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 260-310 micrograms per kilogram.

Abstract

The invention discloses a formula and a cultivation method of selenium-enriched rice. Before the seedlings are transplanted, the selenium-rich base fertilizer is applied in the paddy fields. The selenium-rich base fertilizer is made of a mixture of selenium-containing inorganic compounds, phosphate fertilizer, poultry manure and green manure, and is evenly applied and buried in the soil when preparing the soil. 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 foliar fertilizer is made by dissolving selenium-containing inorganic compounds in traditional Chinese medicine extracts. The invention enables the rice to have multiple opportunities to ingest selenium from nutrition during the growth and development process, is beneficial to increasing the selenium content of the rice, and has health care effects. 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 and a cultivation method of selenium-enriched 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. Obtaining selenium from food is an effective way to increase people's selenium intake. 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 the 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 as...
