Selenium-enriched plant extract compound fertilizer and preparation method thereof

Abstract

The invention belongs to the field of biological fertilizers, and particularly discloses a selenium-enriched plant extract compound fertilizer and a preparation method thereof. The fertilizer mainly comprises an inorganic fertilizer, an organic fertilizer and a microbial fertilizer, and is composed of the following components in parts by weight: 30-60 parts of inorganic fertilizer, 20-25 parts of pepper, 10-15 parts of tobacco leaf, 15-20 parts of allicin, 10-15 parts of dongguo, 20-25 parts of mint and 0.5-1.5 parts of Na2SeO3.The selenium-enriched plant extract compound fertilizer provided by the invention can improve the soil structure, is wide in application range and can effectively increase the survival rate of a crop at a seedling stage; the pepper, tobacco leaf, allicin, dongguo, mint and the like are organically combined to interact, so that the pesticide composition takes the pesticide effect to the greatest extent; and the fertilizer has the advantages of relatively high raw material accessibility, low preparation cost, resistance development postponing and reagent service life prolonging.

Description

[0001] field of invention [0002] The invention belongs to the field of biological fertilizers, and in particular relates to a selenium-enriched plant extract compound fertilizer and a preparation method thereof. Background technique [0003] Biological fertilizer in a narrow sense refers to microbial (bacterial) fertilizer, referred to as bacterial fertilizer, also known as microbial inoculant. It is fermented (artificially cultivated) by microorganisms with special effects, and contains a large number of beneficial microorganisms. After being applied to the soil, it can either fix nitrogen in the air, or activate nutrients in the soil, and improve plant nutrition. The environment, or in the course of the life activities of microorganisms, produces active substances to stimulate the growth of specific microbial products of plants. The extensive use of various pesticides has led to higher and higher resistance of agricultural pests, such as rice planthoppers, rice stem borer...

AI Technical Summary

Problems solved by technology

The surface soil structure of the hilly slope is loose and easy to erode, and the soil erosion is serious, causing a large loss of soil moisture and nutrients, resulting in the degradation of soil fertility and the reduction of fertilization effect, which limits the increase of slope productivity.

At present, most of the microorganisms are used to improve the soil. However, most of the bacteria contained in the bio-fertilizers in the market have poor adaptability to the natural environment, and the effect on land improvement is not obvious.
