Abstract

The invention provides a planting method of selenium-enriched paddy and belongs to the field of agricultural planting. The planting method specifically includes following steps: selecting land suitable for paddy to grow, preparing soil in the land, and applying base fertilizer prepared from self-made organic fertilizer, phosphatic fertilizer and potassium into soil, wherein the self-made organic fertilizer is prepared by mixing and fermenting paddy stalk, coconut shell, kelp, maple leaf, bagasse, tea seed cake, buffalo manure, sheep manure, human manure and urine and rotting acceleration agent; putting seeds after going through selenium-enriched treatment into a seedling raising tray for seedling raising, and transplanting seedlings into the land 25-30 days later; regulating fertilizing and management at different growing stages of the paddy after transplanting till harvesting. By the planting method, survival rate of the paddy can be increased, fertilizer can be saved, yield can be increased, content of selenium element in paddy rice can be increased, and product nutrient value can be increased; the planting method is suitable for large-scale systematic planting and can increase yield and incoming of growers.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of agricultural planting, in particular to a method for planting selenium-enriched rice. [0003] 【Background technique】 [0004] Selenium is an essential trace mineral nutrient for the human body. The "Daily Dietary Nutrient Supply Amount" revised by the Chinese Nutrition Society in October 1998 has listed selenium as one of the 15 daily dietary nutrient elements. The proper daily intake of selenium is 50-250μg. The total content of selenium in the human body is 6-20 mg, and 70% of the human body lacks selenium. Once the human body lacks selenium, it will easily lead to a decline in immunity, thereby causing various diseases, such as cardiovascular disease, liver disease, cataract, Pancreatic diseases, diabetes, reproductive system diseases, etc. Since there is no organ that can store selenium for a long time in the human body, the selenium needed by the human body can only be supplemented continu...
