Rich-selenium biological organic fertilizer and preparation method thereof

Abstract

The invention relates to a rich-selenium biological organic fertilizer and a preparation method thereof. The selenium fertilizer is prepared by mainly proportioning, processing and synthesizing 10-30 percent of chelate selenium solution, 10-30 percent of chelate zinc solution, 20-40 percent of chelate iron solution, 10-30 percent of boric acid solution, 1-10 percent of antagonist, 10-30 percent of water and 30-50 percent of chelate selenium. The selenium fertilizer has the activation function of enriching nutrient components and activating enzyme, improves the utilization ratio of a nitrogenelement by 11-15 percent, improves the absorbing conversion ratio of selenium by 20 percent and can increase the yield of rice and lead the organic selenium content in the rice to reach 100-300 microgrammes / kg simultaneously; the produced rice has the characteristics of better quality, , rich selenium, environmental protection, and the like.

Description

technical field

[0001] The invention relates to an organic selenium fertilizer, in particular to a selenium-enriched bio-organic fertilizer for rice production, and to a preparation method of the bio-organic fertilizer. Background technique

[0002] Selenium is one of the extremely important trace elements for human body and animals. Although the content of selenium in the human body and animals is very small, it has extremely important physiological functions. The human body mainly obtains selenium through diet, so whether the human body is deficient in selenium depends to a large extent on the level of selenium in the food. There are three ways to supplement selenium: clinical selenium supplementation salts, the dosage is difficult to grasp, and the side effects are large, so it is difficult to popularize and apply; taking selenium-containing health care products, such as Fuselenkang, Golden Partner, Sewang Capsules, etc., is expensive, and the majority of residents and ...
