Problems solved by technology

(3) Autotoxicity of plants
At present, the prevention and control measures for soil-borne diseases include the application of organic matter, removal of diseased residues, biological control, adjustment of soil physical and chemical properties, chemical control, soil replacement, soil disinfection and other measures to control the occurrence of soil-borne diseases, but none of them are effective. Preventing the occurrence of devastating soil-borne diseases creates new problems
The effect of chemical control is not satisfactory, the resistance of pathogens increases, and soil and water are polluted; the effect of biological control is unstable; soil replacement and soil disinfection require a large amount of engineering and damage the soil environment

Embodiment 1

[0040] A soil conditioner, the components are as follows, all in parts by weight:

[0041] 15 parts of biochemical fulvic acid (BFA), 10 parts of polyacrylamide, 10 parts of burdock fructooligosaccharide, 10 parts of chitosan, 5 parts of zinc sulfate, 2 parts of boric acid, 70 parts of Trichoderma pseudokonii fermentation broth.

[0042] The above-mentioned soil conditioner is prepared by the following method, and the steps are as follows:

[0043] (1) Take the dry powder of burdock root, extract 3 times with 10 times the volume of 70°C water, combine the extracts, concentrate in vacuum at 60°C to a quarter of the original volume, then add 3 times the volume of 95% ethanol for precipitation, Take the precipitate and dissolve it in water, freeze-dry to obtain burdock fructooligosaccharide; after testing, the molecular weight is 2310, and the uniformity is 85.0%.

[0044] (2) Take Trichoderma pseudoconii with the strain preservation number CGMCC No.3.3002, insert it into PDA liqu...

Abstract

The invention relates to a soil conditioner as well as a preparation method and application of the soil conditioner. The soil conditioner comprises the components based on parts by weight: 10-15 parts of biochemical fulvic acid, 10-20 parts of polyacrylamide, 5-10 parts of burdock oligosaccharide, 5-10 parts of chitosan, 1-5 parts of zinc sulfate, 1-2 parts of boric acid and 50-70 parts of trichoderma pseudokoningii fermentation liquor. The invention also provides the preparation method and the application of the soil conditioner. According to the invention, biochemical fulvic acid and the polyacrylamide are combined, and trace elements zinc and boron, the disease-resistant elicitor burdock oligosaccharide, chitosan and the biological control fungi trichoderma pseudokoningii which are necessary to plants and deficient in the soil are loaded, so that the soil conditioner having the functions of improving the physicochemical property of the soil, inhibiting the soil-borne diseases, promoting the growth of the plants and inducing the resistance of botanical system is prepared, and is environment-friendly.

Description

technical field [0001] The invention relates to a soil improver and its preparation method and application, belonging to the technical field of soil improver. Background technique [0002] With the continuous progress of agriculture, protected area production has become an important pillar industry for the development of contemporary agricultural economy. Due to the one-sided pursuit of yield and blindly increasing the input of water, fertilizer, and pesticides, a series of serious problems restricting sustainable production have appeared in protected areas, such as the deterioration of soil physical and chemical properties caused by improper water and fertilizer management, and the imbalance of nutrients in the soil. In addition, the spread of soil-borne diseases caused by long-term continuous cropping has become one of the main obstacles to the production of vegetables in protected areas. Many vegetable protected areas have to be converted to open field cultivation due to ...
