Embodiment 1

[0031] A method for planting selenium-enriched rice, including seedling cultivation, transplanting and rice fertilization methods. The planting method adds base fertilizer in the transplanted rice field one day before the transplanting of the rice seedlings; 10 days after the transplanting of the seedlings is completed , Increase the application of selenium-enriched fertilizers, the selenium-enriched fertilizers include selenium-containing compounds, potassium fertilizers, silicon fertilizers, nitrogen fertilizers, and phosphate fertilizers; in the early stage of rice spitting and blooming, selenium-enriched fertilizers are added to the rice.

[0032] The base fertilizer is a mixture of chemical fertilizer and organic biological fertilizer, and the two are mixed in a mixer according to a mass ratio of 40:33 for 1 hour, and then placed in a closed plastic bag for 0.5 days.

[0033] The chemical fertilizer is urea, and the biological fertilizer is a granular material made by mixing an...

Embodiment 2

[0043] Three days before transplanting rice seedlings, add base fertilizer in the transplanted rice field. The base fertilizer is a mixture of chemical fertilizer and organic and biological fertilizer. The two are mixed in a mixer at a mass ratio of 67:45 for 1 hour, and then placed Place it in a sealed plastic bag for 1 day; 15 days after the seedlings are transplanted, add selenium-enriched fertilizer, which is composed of selenium-containing compounds, potassium fertilizer, silicon fertilizer, nitrogen fertilizer and phosphate fertilizer in accordance with 62:38:33:28: It is mixed with a ratio of 23; in the early stage of rice spitting and blooming, the rice is added with selenium fertilizer.

[0044] The chemical fertilizer is urea, and the biological fertilizer is a granular material made by mixing and drying cow manure, pig manure and chicken manure in a ratio of 43:35:22, and the moisture content is guaranteed to be 25% after drying.

[0045] The base fertilizer is a granula...

Abstract

The invention relates to the technical field of high-quality crops planting, and particularly relates to a planting method of selenium-enriched rice; the planting method of the selenium-enriched rice includes steps of rice seedling cultivation, transplanting and rice fertilization; according to the planting method, base fertilizer is applied to the transplanting rice before transplanting the rice seedling for 1-3 days; after completing the seedling transplanting for 10-15 days, the selenium-enriched fertilizer is applied; the selenium-enriched fertilizer includes selenium-enriched compound, potash fertilizer, silicon fertilizer, nitrogen fertilizer and phosphatic fertilizer; at the beginning period of rice panicle emergency and flowering, the rice is further added with selenium-enriched fertilizer. The planting method has good practicability and promotion prospect.

Description

Technical field [0001] The invention relates to the technical field of high-quality crop cultivation, in particular to a method for planting selenium-rich rice. Background technique [0002] Selenium is an essential trace element for humans and animals. It is an antioxidant. It has the effect of relieving aging and can eliminate a variety of harmful free radicals. Its synergistic effect with vitamin E is called the "golden partner" of antioxidants. The lack of selenium will lead to the decline of human immunity, Keshan disease and Kashin-Beck disease, severe selenium deficiency will cause various diseases such as coronary heart disease, hemolytic anemia and liver cancer. At present, the number of people with selenium deficiency worldwide is estimated to be 50 million to 100 million, which shows the importance of supplemental absorption of selenium to human health. [0003] The results of the census in my country (13 provinces) show that the per capita daily intake of selenium is o...
