Rape straw fermentation organic fertilizer and preparation method thereof

Abstract

The invention discloses rape straw fermentation organic fertilizer and a preparation method thereof. The rape straw fermentation organic fertilizer is prepared from the following components in parts by weight: 30-50 parts of peat soil, 30-50 parts of rape straw, 3-5 parts of traditional Chinese medicine residues, 3-5 parts of fish bone powder, 0.5-2 parts of micro element fertilizer, 0.5-1 part of a microbial agent, and 0.5-2 parts of fermentation powder. The traditional Chinese medicine residues comprise 35% of rheum officinale residues, 35% of fructus corni residues and 30% of cortex magnoliae officinalis residues. The preparation method for the rape straw fermentation organic fertilizer comprises the following process: (1) corn straw fermentation; (2) traditional Chinese medicine residue enzymolysis; (3) crushing; (4) mixing; (5) pelletizing; and (6) drying. The rape straw fermentation organic fertilizer disclosed by the invention is prepared from the peat soil, the rape straw, the traditional Chinese medicine residues, the fish bone powder and the micro element fertilizer, is reasonable in formula, can meet various needs for crop growth, and sufficiently utilizes the traditional Chinese medicine residues; and while waste is utilized, disease resistance of crops is improved.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a rape stalk fermented organic fertilizer and a preparation method thereof. Background technique [0002] With the development of agriculture, more and more farmers have seriously neglected the protection and cultivation of soil fertility in order to pursue short-term interests, and applied a large amount of chemical fertilizers and pesticides, which left chemical fertilizers and pesticides in the soil, which led to soil compaction, deterioration of physical and chemical properties, The content of organic matter and beneficial microorganisms in the soil has dropped sharply, resulting in a decline in soil fertility, and some decomposition products of chemical fertilizers have also polluted the soil and groundwater. Agricultural production is the source of food. In the process of plant growth, the improper use of external input materials has caused increasingly serious and prom...
