example 1
[0057] Example 1, soil improvement of the present invention, anti-heavy cropping multifunctional biological preparation is formulated from the following raw materials by weight (parts):
[0059] Example 2, soil improvement of the present invention, anti-heavy cropping multifunctional biological preparation is formulated from the following raw materials by weight (parts):
[0061] Example 3, soil improvement of the present invention, anti-stubble multifunctional biological preparation is formulated from the following raw materials by weight (parts): Trichoderma pseudoconii fermented liquid 20, Bacillus fermented liquid 25, fulvic acid 20, zinc sulfate 5. Vitamin C 7, α naphthalene acetic acid 0.8, chlorogenic acid 9, aminosalicylic acid 6, dextrin 8, add water to 100 parts.
[0062] The preparation method of the above-mentioned soil improvement and anti-heavy cropping multifunctional biological preparation is as follows:
[0063] ① Fermentation method of Trichoderma pseudoconii: Aseptic operation should be performed during processing; first, the strain of Trichoderma pseudoconii was activated on a PDA plate for 24 hours, and then placed in a liquid PDA triangular flask, cultured at 28°C, 100r / min for 36 hours Obtain the seed liquid, receive in the seed tank by 3% inoculum, stir and ventilate and cultivate for 36 hours, then enter the secondary ...

Abstract
The invention provides a soil improvement and anti continuous cropping multifunctional biological agent which contains the mixed microorganism of trichoderma pseudokoningii and bacillus subtilis, faveolate humic acid and zinc sulphate; the trichoderma pseudokoningii is a bacterial strain obtained by separating and screening maize straw; the bacterial strain is named after (Trichoderma pseudokoningii) DLDI and is preserved in China general microbiological culture collection (CGMCC), and the number thereof is CGMCC NO.3221; the bacillus subtilis obtained by separating soil is named after (bacillus subtilis) DLD2 and is preserved in China general microbiological culture collection (CGMCC), and the number is CGMCCNO.3222; the biological agent has the effects that (1) biocontrol microorganism is used for blocking harmful flora from infecting plants and killing pathogenic bacteria, induces the plants to generate disease resistance and prevents dead seedlings from rotting roots; (2) the microorganism and the faveolate humic acid are compounded to induce the root system to grow, thus realizing root regeneration and plant regeneration and inhibiting the anti continuous cropping diseases; and (3) the faveolate humic acid and the zinc sulphate are used for breaking the soil hardening of the soil, forming the crumble structure, realizing no deep ploughing, retaining water, alleviating fertilizer damage and increasing the soil productivity.
Description
technical field [0001] The invention relates to the fields of soil improver and soil anti-cropping agent, in particular to a multifunctional biological agent with two effects of soil improving and anti-cropping agent in one and a preparation method thereof. Background technique [0002] Good soil conditions are a necessary condition for high crop yields, but due to drought, excessive use of chemical fertilizers, unreasonable cultivation and management, continuous cropping and other reasons, soil ecology deteriorates, crop production decreases, and huge economic losses are caused. The main impacts of soil ecological deterioration on crops are root water, vapor, and fertilizer imbalances caused by soil compaction and heavy cropping diseases caused by heavy cropping pathogens. Exploring effective methods to break soil compaction and control cropping diseases has huge economic benefits and social significance. [0003] At present, the methods for breaking soil compaction are ma...
