Selenium enriched plant extract composite film forming regulator and preparation method thereof

Abstract

The invention belongs to the field of biological fertilizers, and in particular discloses a selenium enriched plant extract composite film forming regulator and a preparation method thereof. The selenium enriched plant extract composite film forming regulator mainly includes an inorganic fertilizer, an organic fertilizer and a microbial fertilizer. The selenium enriched plant extract composite film forming regulator comprises the following components: 30-60 parts of an inorganic fertilizer, 10-15 parts of Rhizoma Bletillae, 10-15 parts of garden burnet, 5-10 parts of catechu, 5-15 parts of Coptis chinensis, 15-25 parts of polyvinyl alcohol, 20-25 parts of sodium carboxymethylcellulose and 0.5-1.5 parts of Na2SeO3. The selenium enriched plant extract composite film forming regulator can improve the soil structure, has a wide application range, and can effectively improve the survival rate of seedling-forming-period crops; by organic combination and interaction of pepper, tobacco leaf, allicin, dongguo, mint and the like, the drug effect of the pesticide composition can be played to the largest degree, raw materials are relatively easy to get, production cost is low, development of resistance is delayed, and the service life is prolonged.

Description

[0001] field of invention [0002] The invention belongs to the field of biological fertilizers, in particular to a composite film-forming regulator of selenium-enriched plant extracts 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 ...

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.
