Selenium-rich compound microorganism fertilizer and preparation method thereof

Abstract

The invention discloses a selenium-rich compound microorganism fertilizer and a preparation method thereof. The selenium-rich compound microorganism fertilizer is prepared from the following ingredients: 5 to 12 weight parts of enzyme microorganism, 10 to 30 weight parts of humic acid, 5 to 15 weight parts of amino acid, 1 to 5 weight parts of traditional Chinese medicine extracts, 1 to 5 weight parts of sodium selenite, 20 to 30 weight parts of macroelements, 1 to 5 weight parts of water-retaining agents and 5 to 15 weight parts of shale. The enzyme microorganism, the humic acid, the amino acid, the traditional Chinese medicine extracts, the sodium selenite, the macroelements, the water-retaining agents and the shale are used as raw materials; the prepared fertilizer can obviously activate microorganisms in soil; the microorganism metabolism is improved; the number of the soil enzyme is increased, so that the hardened soil is loosened. The fertilizer provided by the invention has the advantages that the yield can be increased; the selenium can be increased; the crop quality is improved; the crop expiration date is prolonged; the soil can also be improved; heavy metal in the soil is degraded; the physical and chemical properties of the soil can also be improved; the soil PH value is regulated; the soil fertilizer retention and water retention capability is enhanced; the fertilizer utilization rate is effectively improved.

Description

technical field [0001] The invention relates to the field of compound biological fertilizer bags, in particular to a selenium-enriched compound biological fertilizer and a preparation method thereof. Background technique [0002] At present, in terms of crop cultivation in my country, most of them still use chemical fertilizers. Although they have a certain effect on increasing production and income, long-term application will cause many disadvantages: 1. Destroy the soil, resulting in a decrease in soil organic matter content and imbalances in the proportion of various nutrients. The soil begins to acidify and compact, and the physical and chemical properties of the soil and soil microbial flora are severely damaged, resulting in poor water retention, fertilizer retention, and air permeability, which are difficult to meet the actual growth needs of crops; 2. Crops are highly dependent on chemical fertilizers and pesticides, and must Increase the amount of periodical use year ...

AI Technical Summary

Problems solved by technology

[0003] The above conditions can be improved by applying organic fertilizers, but many domestic varieties of biological fertilizers, microbial fertilizers, biological phosphate fertilizers, and biological potassium fertilizers cannot improve the compaction of the soil.
