Abstract

The invention discloses selenium-enriched organic compound fertilizer and its application in rice. The fertilizer comprises, by weight, 60-80 parts of cow dung, 80-100 parts of horse dung, 20-40 parts of crayfish shell flour, 20-30 parts of plant ash, 40-60 parts of wheat straws, 20-30 parts of astragalus smicus powder, 30-40 parts of diatomite, 10-16 parts of potassium humate, 4-6 parts of sodium selenite, 6-8 parts of urea, 10-12 parts of calcium superphosphate, 10-14 parts of a microbial agent, 1-2 parts of magnesium sulfate and 800-1000 parts of water. In rice application, the fertilizer is diluted by water according to a mass ratio of 1: 500 and then is applied to the leaf surface in a heading period and a full heading stage. The organic compound fertilizer has the characteristics of organic selenium fertilizer and inorganic selenium fertilizer, improves the absorption and enrichment of selenium in rice, promote plant growth, produce effects fast and keep long-term fertilizer efficiency.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a selenium-rich organic compound fertilizer and its application on rice. Background technique [0002] Selenium is a non-metallic element that exists in nature and is an essential trace element for human and animal health. There are more than 30 kinds of selenoproteins in mammals. Selenium has anti-oxidation, detoxification, cancer prevention, and immunity enhancement in the human body. Selenium is the most serious lack of mineral elements except iron, zinc and iodine. There are about 1 billion people in the world who are deficient in selenium. Severe selenium deficiency can lead to Keshan disease and Kassin-Baker's disease (big bone disease), In addition, selenium deficiency is also related to cancer, cardiovascular disease, asthma and other diseases. According to the report of the Chinese Nutrition Society, the total selenium intake per capita is only 26-32 μg / d, which is ...
