The invention has the following beneficial effects:
the biological additive can effectively promote the decomposition and release of soluble phosphorus and potassium elements, calcium, sulfur, magnesium, iron, zinc, molybdenum and manganese and other medium and trace elements in alfalfa green manure and soil, and increase the absorption of phosphorus and potassium elements, calcium, sulfur, magnesium, iron, zinc, molybdenum and manganese and other medium and trace elements by rice, so that the rice yield is increased, the growth of the rice can be promoted, and the disease incidence rate in the rice planting process is reduced.
Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that variations and modifications can be made by persons skilled in the art without departing from the spirit of the invention. All falling within the scope of the present invention.
Preparing raw materials:
alfalfa fermentation liquor: chopping alfalfa, pulping with distilled water, filtering, adding sodium chloride at a ratio of 0.5g/Kg, sealing, and fermenting in dark for 72h to obtain the final product;
and (3) microbial agent: taking a proper amount of trichoderma longibrachiatum T6, Bacillus mucilaginosus (Bacillus mucoginosus) and cellucophagus hatsuensis (Cytophagahutchinonii) fermentation liquor for compounding, and preparing the fermentation liquor containing the trichoderma longibrachiatum T61 multiplied by 1010CFU/m, Bacillus mucilaginosus (Bacillus mucoarginosus) 1X 1010CFU/m, Cytophagahutchusonii (Cytophagahutchinonii) 1X 1010CFU/m microbial inoculum.
Beet molasses, soybean peptide: and (5) outsourcing.
Example 1
A biological additive for enhancing the efficiency of alfalfa green manure is prepared by mixing and fermenting a microbial agent, alfalfa fermentation liquor, beet molasses, soybean peptide and clear water, wherein the microbial agent consists of 5 percent of the mass of the alfalfa fermentation liquor; the using amount of the beet molasses is 3 percent of the mass of the alfalfa fermentation liquor; the dosage of the soybean peptide is 1 percent of the mass of the alfalfa fermentation liquor; the amount of the clear water is 6 times of the fermentation liquor of the alfalfa.
Example 2
The biological additive is prepared by mixing and fermenting a microbial agent, alfalfa fermentation liquor, beet molasses, soybean peptide and clear water, wherein the microbial agent consists of 6 percent of the mass of the alfalfa fermentation liquor; the using amount of the beet molasses is 6 percent of the mass of the alfalfa fermentation liquor; the using amount of the soybean peptide is 3 percent of the mass of the alfalfa fermentation liquor; the amount of the clear water is 6 times of the fermentation liquor of the alfalfa.
