Green and pollution-free organic fertilizer and preparation method thereof

Abstract

The invention discloses a green and pollution-free organic fertilizer, comprising the following raw materials in parts by weight: 25-36 parts of maize meal, 22-36 parts of rice bran, 20-30 parts of wheat bran, 14-20 parts of soybean cake powder, 12-16 parts of wormcast, 8-12 parts of urea, 6-8 parts of turf, 6-8 parts of perlite, 6-7 parts of pine needle meal, 5-6 parts of tobacco powder, 4-5 parts of powdered rock phosphate, 3-4 parts of brown sugar, 2-3 parts of actinomycetes, 2-3 parts of enzyme microorganism and a proper amount of water. According to the fertilizer disclosed by the invention, the maize meal, the rice bran, the wheat bran and the like are adopted as main raw materials, the soybean cake powder, the wormcast, the urea, the tuft and the like are adopted as auxiliary materials, the organic fertilizer is free of pollution to the natural environment and the soil when comprehensive nutrients are supplied to crops, the effective living bacteria in the fertilizer are high in quantity by combination of the added enzyme microorganism and actinomycetes, various animal and plant residues in the soil can be quickly decomposed, chemical components such as pesticide residues and chemical fertilizers, and refractory minerals also can be decomposed, the pollution on the soil and agricultural products caused by the chemical fertilizers and pesticides can be reduced, the high-yield, high-quality and pollution-free effects are achieved, and the organic fertilizer accords with the sustainable development of agriculture, and has good popularization and application value.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a green and pollution-free organic fertilizer and a preparation method thereof. Background technique [0002] Although traditional inorganic chemical fertilizers have high nutrient content and rapid fertilizer effect, their fertilizer effect is strong but not long-lasting, and the effect of improving soil is not great, and even has side effects of destroying soil properties. The large-scale use of inorganic chemical fertilizers in agricultural production will bring such as Various problems such as quality decline, soil compaction, and water pollution. With the improvement of people's living standards, residents' demand for safe, hygienic and pollution-free organic and green food continues to increase. The majority of farmers urgently need to use organic fertilizers to improve the market competitiveness of agricultural products. Organic fertilizers are rich in organic matter ...
