Composite fermented microbial soil conditioner and preparation method thereof

Abstract

The invention discloses a composite fermented microbial soil conditioner and a preparation method thereof. The composite fermented microbial soil conditioner comprises 10-20 ml of actinomycetes fermentation liquor, 10-30 ml of saccharomycetes fermentation liquor, 10-40 ml of lactobacillus fermentation liquor, 10-50 ml of bacillus fermentation liquor, 10-20 ml of photosynthetic bacteria fermentation liquor, 5-15 g of actinomycetes powder, 3-8 g of saccharomycetes powder, 5-15 g of lactobacillus powder, 10-30 g of bacillus powder, 3-8 g of photosynthetic bacteria powder and 50-100 kg of an organic material of which C: N= 20-25: 1. The invention provides the composite microbial agent which promotes fertility absorption in soil, improves physical and chemical properties of soil, improves soilcaking caused by a large amount of fertilization for a long time, increases the content of beneficial bacteria of the soil, increases the content of organic matters of the soil, promotes growth of root systems of plants, inhibits soil-borne diseases and improves disease resistance of crops and a preparation method of the composite microbial agent. The method is environmentally friendly, pollution-free, low-carbon, efficient, short in period, low in cost and simple to operate.

Description

technical field [0001] The invention relates to the field of biology, in particular to a compound fermentation microbial soil improver and a preparation method thereof. Background technique [0002] At present, there are many microbial agents for improving soil on the market, and these microbial agents all have a certain effect of improving soil. [0003] After years of laboratory research and field application and observation, it was found that although these microbial preparations have the effect of improving soil, their formulas are relatively complicated and unscientific. Inhibition does not take into account whether the activity of the bacteria is inactivated after mixing, and whether the fermentation metabolites are mutually utilized to cause secondary fermentation. The practical operation is not convenient and scientific, and the effect of improving the soil is not obvious. Contents of the invention [0004] In view of the above problems, the present invention prop...

[0003] After years of laboratory research and field application and observation, it was found that although these microbial preparations have the effect of improving soil, their formulas are relatively complicated and unscientific. Inhibition, without considering whether the activity of the bacteria is inactivated after mixing, whether the fermentation metabolites are mutually utilized to cause secondary fermentation, the practical operation is not convenient and scientific, and the effect of improving the soil is not obvious
