example 1
[0042] Example 1, soil improvement of the present invention, anti-heavy cropping multifunctional biological preparation is formulated from the following raw materials by weight (parts):
[0044] Example 2, soil improvement of the present invention, anti-heavy cropping multifunctional biological preparation is formulated from the following raw materials by weight (parts):
[0046] Example 3, soil improvement of the present invention, anti-heavy cropping multifunctional biological preparation is formulated from the following raw materials by weight (parts):
[0048] The preparation method of soil improvement and anti-heavy cropping multifunctional biological preparation of the present invention:
[0049] ①Preparation method of Bacillus subtilis fermentation broth: (Sterile operation should be performed during processing)
[0050] The Bacillus subtilis strains were activated on LB plates, placed in liquid LB medium (tryptone 10g / L, yeast extract 5g / L, NaCl 10g / L), and cultured on a shaking table at 28°C and 120rpm for 24h According to 3% inoculation amount, carry out agitation and aeration culture in the seed tank for 24 hours, then enter the secondary s...

technical field [0001] The invention is a multifunctional biological agent containing bacillus subtilis, and relates to the formula and preparation method of soil improvement and anti-stubble agent. 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 mainly mechanical deep plowing and application of soil amendm...
