Biological type nematode-preventing soil conditioner and preparation method thereof

Abstract

The invention discloses a biological type nematode-preventing soil conditioner and a preparation method thereof. The biological type nematode-preventing soil conditioner comprises the following components in parts by weight: 20-40 parts of abamectin residues, 20-80 parts of oyster shell powder, and 1-3 parts of microbial agent. The biological type soil conditioner which has a nematode expelling function and is prepared by taking waste residues obtained in producing abamectin as main raw materials, adsorbing a microbial preparation and blending the natural marine biological resource oyster shell powder provides abundant organic matters by using the abamectin residues, improves the soil micro-ecological environment by utilizing the composite microbial preparation with phosphate solubilizing bacteria, potassium solubilizing bacteria, bacillus subtilis and the like, carries out disinfection and desinsection on soil, is capable of regulating the soil acidity and alkalinity by using the oyster shell powder and efficiently preventing and controlling the soil insects and the nematodes, has no chemical residue and is favorable to crop growth. The preparation method of the biological type nematode-preventing soil conditioner, which is disclosed by the invention, has the advantages of simple process and low cost.

Description

technical field [0001] The invention relates to a composite soil conditioner and a preparation method thereof, in particular to a biological type anti-nematode soil conditioner and a preparation method thereof. Background technique [0002] In agricultural production, more and more problems are comprehensively reflected, such as soil pH, plant parasitic nematodes, etc. Soil pH is critical to plant growth, and most crops will thrive in neutral or slightly acidic soil. However, the US journal Science once reported that from the early 1980s to the present, the pH of almost all soil types found in China has dropped by 0.1 to 0.8 units, and soil acidification on this scale "usually takes hundreds of thousands of years time", soil acidification may be caused by acid rain. However, in order to obtain higher yields, Chinese farmers lack a little bit of traditional agricultural measures such as applying lime, burning manure, and applying organic fertilizers, which makes the soil nu...

Problems solved by technology

In particular, due to the rapid expansion of the area of ​​vegetables in protected areas in China, uninterrupted planting throughout the year has resulted in a large accumulation of nematodes and other pathogenic microorganisms, resulting in reduced vegetable production, seriously affecting the quality and export of vegetables, and seriously threatening the production of vegetables in protected areas.
