Organic fermented fertilizer for raising selenium content of vegetables, production method and cultivation method

Abstract

The invention discloses an organic fermented fertilizer for raising the selenium content of vegetables, a production method and a cultivation method and relates to the field of vegetable production.The production method of the organic fermented fertilizer comprises the steps of preparing materials, wherein 35-45 parts of fresh cow dung, 30-36 parts of plant straw, 8-12 parts of mushroom residues, 8-12 parts of coal slag, 5.6-6 parts of wheat bran, 0.8-1.2 parts of brown sugar and 0.1-0.3 part of a microbial agent are prepared; conducting amplification cultivation on microbial flora; mixing the raw materials, and conducting anaerobic fermentation and aerobic fermentation, so that the organic fermented fertilizer is obtained.The cultivation method comprises the step of scattering and applying an alkaline soil improvement agent and the fermented fertilizer at different stages before the vegetables are planted.According to the organic fermented fertilizer for raising the selenium content of the vegetables, the production method and the cultivation method, fermentation treatment is conducted on industrial and agricultural waste, the organic fermented fertilizer is generated, the problem that the industrial and agricultural waste causes environmental pollution is solved, and in addition, by means of the organic fermented fertilizer, fertilizer efficiency of the soil where the vegetables are planted can be enhanced; by applying the organic fermented fertilizer and the alkaline improvement agent in different time, the selenium enrichment effect of the planted vegetables can be obviously improved.

Description

technical field [0001] The invention relates to the field of vegetable production, in particular to an organic fermented fertilizer for increasing the selenium content of vegetables, a production method and a cultivation method. Background technique [0002] Selenium is an essential trace element for human and animal life. 72% of China's areas are selenium-deficient areas, 1 / 3 of which are seriously deficient in selenium, about 700 million people live in low-selenium areas, and 2 / 3 of the population There are different degrees of selenium intake deficiency. Selenium deficiency can lead to the occurrence of a series of diseases such as cardiovascular disease, Keshan disease, and Kaschin-Beck disease. Supplementing selenium has various biological functions such as enhancing human immunity, preventing cardiovascular diseases, anti-tumor, beautifying and anti-aging, and has certain regulatory effects on AIDS, thyroid disease, Kashin-Beck disease, Parkinson's disease, etc. Ther...
