Liquid micro-element fertilizer containing bacillus subtilis fermentation liquor and preparation method and usage method thereof

Abstract

The invention discloses a liquid micro-element fertilizer containing a bacillus subtilis fermentation liquor and a preparation method and a usage method thereof. The liquid micro-element fertilizer is prepared from the bacillus subtilis fermentation liquor, calcium chloride, magnesium sulfate, ferrous sulfate, zinc sulfate, sodium borate, bismuth molybdate, alkaline cupric tartrate, manganese sulfate and humic acid, contains rich trace elements and is stable in fertilizer effect, cheap and environmentally friendly. The preparation method is simple and easy to use, can be used for pollution-free fruits and vegetables and other high value-added agricultural products and has a good application prospect.

Description

technical field [0001] The invention belongs to the field of fertilizers, in particular to a liquid micro-fertilizer containing a Bacillus subtilis fermentation liquid, and also to a preparation method and a use method of the liquid micro-fertilizer. Background technique [0002] Bacillus subtilis fermentation liquid is the discarded liquid part in the process of liquid fermentation of Bacillus subtilis bacteria. It contains rich polypeptides, some antibiotics, active enzymes, etc., and can prevent and control various diseases and insect pests. However, most of the Bacillus subtilis preparations used in agricultural production are used Pure bacterial powder is obtained by filtering the fermented liquid to obtain bacterial slime and drying. The filtered liquid is used as sewage for subsequent treatment. However, due to the large amount of fermented liquid, it cannot be completely digested and causes environmental pollution. Therefore, the existing treatment methods waste resou...

[0002] Bacillus subtilis fermentation liquid is the discarded liquid part in the process of liquid fermentation of Bacillus subtilis bacteria. It contains rich polypeptides, some antibiotics, active enzymes, etc., and can prevent and control various diseases and insect pests. However, most of the Bacillus subtilis preparations used in agricultural production are used Pure bacterial powder is obtained by filtering the fermented liquid to obtain bacterial slime and drying. The filtered liquid is used as sewage for subsequent treatment. However, due to the large amount of fermented liquid, it cannot be completely digested and causes environmental pollution. Therefore, the existing treatment methods waste resources. , wasted money

And Bacillus subtilis fermentation broth contains water-soluble various nutrients and rich organic matter, if it is utilized, it not only has fertilizer effect, but also helps soil microbial activity and soil aggregate structure formation, but the effect of single application of Bacillus subtilis fermentation fluid is effective, need Used in conjunction with other plant essential trace elements
