Abstract

The invention discloses a preparation method of bio-organic fertilizer. The preparation method can produce selenium-rich silicon-rich bio-organic fertilizer. The bio-organic fertilizer has high organic selenium and organic silicon contents. Through the bio-organic fertilizer, crops can absorb a large amount of selenium and silicon. A complex microbial agent has effects of dissolving phosphorus, fixing nitrogen and improving soil fertility and significantly improves content of a variety of trace minerals in fruits. The preparation method has simple processes, realizes a low preparation cost and is suitable for industrial production. The bio-organic fertilizer does not easily lose nutrients and has lasting fertilizer efficiency. Through raw material fermentation, the fermentation product is rich in selenium so that selenium content of the crop fruits is improved, the fruit economic value is improved and planting benefits are significantly improved. The bio-organic fertilizer can significantly improve the selenium content of agricultural products and significantly increase the percentage of organic selenium in total selenium in the agricultural products, is suitable for application of selenium deficient or low selenium regions in China and has the great significance to improve the selenium level. The complex microbial agent can play a role in phosphorus dissolution, nitrogen fixation and soil fertility increasing and can significantly improve the various trace mineral contents of fruits.

Description

technical field [0001] The invention relates to a method for preparing an organic fertilizer, in particular to a method for preparing a bio-organic fertilizer rich in selenium and silicon. Background technique [0002] In recent years, as people pay more and more attention to dietary health and food safety, the quality requirements of agricultural products are getting higher and higher. General waste can no longer meet the nutrient supply of crops, and farmyard manure is mostly used as fertilizer. However, the amount of farmyard manure is limited, and the performance of fertilizer performance is uncontrollable, making it difficult to meet the requirements of high standards. In this case, the role of microbial fertilizer is highlighted. Biological bacterial fertilizer can provide various nutrients for crops through microbial metabolism, improve the living environment of crops, and even participate in certain physiological processes of crops, enhance stress resistance, improv...
