Embodiment 1

[0052] The planting method of selenium-enriched rice comprises the following steps:

[0053] 1) Site selection: Select an agricultural production area with good ecology and environment, far away from pollution sources, and sustainable production capacity in Shanglin County, Nanning City, Guangxi. The ambient air quality, irrigation water quality requirements, and soil environmental quality requirements meet the agricultural industry standards; soil The content of organic matter is more than 2.5%, the content of nitrogen, phosphorus and potassium is more than medium, and other nutrients are rich and balanced.

[0054] 2) Whole field: Use tractor-linked auger drills to mechanically enter the powder ridges. The specific technology adopts the powder ridge technology with the application number 201110146170.7 and the name of the invention: "Method for Cultivating Rice Fen Ridges"; The weight composition is: 20% selenium-enriched base fertilizer + 50% decomposed organic fertilizer +...

Abstract

The invention discloses a selenium-enriched rice planting method. The method includes the following steps of land selecting, field finishing, seed treatment, sowing and seedling raising, seedling transplant, fertilizer management in the later period, irrigation treatment and selenium-enriched rice harvesting. Before seedlings are transplanted, selenium-enriched base fertilizer in a complex state is applied in the rice field, and a certain selenium source is provided for rice; at the beginning of panicle emergence and flowering of rice and grouting, the selenium-enriched compound fertilizer is applied in the rice field again, the selenium-enriched fertilizer is evenly distributed around roots of the seedlings in the growth process, the selenium in a complex state from soil is absorbed by the roots of the plants and then enters the inner cycle systems of the plants and participates in synthesis of protein through the path from stems to leaves to flowers and fruits, and finally, the selenium in an ionic condition from soil is stored in the seeds in the form of selenoprotein. The selenium-enriched rice tastes good and is high in nutrient matter content, and the content of the selenium of the rice can reach over 0.2 mg/kg and meets the national selenium-enriched standard.

Description

technical field [0001] The invention relates to the technical field of rice cultivation, in particular to a method for planting selenium-enriched rice. Background technique [0002] Selenium is a chemical element, the chemical symbol is Se, a non-metal, an essential nutrient element for animals and a beneficial nutrient element for plants. Its content in food depends on the selenium content of the soil in different regions. As long as the soil is rich in selenium, the food grown from it must have selenium. Selenium is an essential vector mineral nutrient for the human body, which cannot be synthesized in the human body. The total selenium content of the human body is 6-20mg. Selenium is distributed throughout various tissues, organs and body fluids, with the highest concentration in the kidney, which is very important for improving immunity and preventing cancer. Since there is no long-term selenium storage organ in the human body, the selenium needed by the body should b...
