Organic fertilizer and preparation method thereof

Abstract

The invention provides organic fertilizer. The organic fertilizer is prepared from, by weight, 20-25 parts of crop straw, 10-15 parts of animal feces, 5-10 parts of humic acid, 5-8 parts of weatheredcoal powder. , 5-8 parts of dipotassium hydrogen phosphate, 5-8 parts of corn cobs, 4-6 parts of seaweed powder, 4-5 parts of urea, 4-5 parts of fish pond sludge, 4-5 parts of fermenting bacteria, 2-4parts of magnesium phosphate, 1-2 parts of sodium molybdate, 1-2 parts of compound sodium nitrophenolate, 0.5-1 part of trace element additive, 0.5-1 part of synergist, 0.5-1 part of conditioning agent, 0.5-1 part of anti-virus agent, 0.5-1 part of soil-modified functional flora and 0.5-1 part of penetrating agent. The agricultural organic fertilizer has the advantages that the fish pond sludge is adopted as the partial raw material, the nutrients of the organic fertilizer can be increased, the flora in the organic fertilizer can also be enriched, the fermentation efficiency and quality of the raw materials of the organic fertilizer are improved accordingly, and the fertilizer efficiency uniformity and stability of the organic fertilizer are improved.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer processing, in particular to an organic fertilizer and a preparation method thereof. Background technique [0002] Organic fertilizers are rich in organic matter and nutrients needed for crop growth. They can not only provide the nutrients needed for crop growth, improve the soil, but also improve crop quality, increase crop yield, promote high and stable crop yields, maintain soil fertility, and increase fertilizer efficiency. Utilization rate, reduce production cost. The full and rational use of organic fertilizers can increase crop yields, improve soil fertility, improve the quality of agricultural products, and increase the effectiveness of soil nutrients. For example, the patent application number 201611116898.4 discloses a kind of organic fertilizer, which solves the problems of low utilization efficiency of existing fertilizers and environmental pollution, but it has low fertili...
