Organic fertilizer for black tea residue stick bean and preparation method thereof

Abstract

The invention discloses an organic fertilizer for black tea residue stick bean and a preparation method thereof. The organic fertilizer for black tea residue stick bean is prepared by the following steps: mixing and fermenting tea residues, decomposed pig manure, bacillus subtilis and enzyme bacteria as a fermented material; then uniformly mixing the fermented material with mixed vinegar-soaked traditional Chinese medicine residue powder; stacking the mixture for 5-8 days; and then uniformly mixing the mixture with a nitrogen phosphorous and potassium fertilizer. The organic fertilizer can improve the lodging resistance and the disease and drought resistance of the stick beans effectively, and the absorption rate of the stick beans is improved. The damage to soil is also alleviated correspondingly. Rotten apple slurry, orange slurry and black tea residues are closely fermented and used. The nutrient content is enriched, the cost is saved and wastes are turned into wealth.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to an organic fertilizer of black tea, tea dregs, stick beans and a preparation method thereof. Background technique [0002] my country is a big producer of chemical fertilizers and a big consumer of chemical fertilizers. Most of the nutrients in organic fertilizers are absorbed by the soil, and the absorption rate of plants is very low, resulting in soil pollution by nitrates and nitrites, soil compaction, and generation of harmful gases. Seriously damaged, with the rapid development of the chemical industry, the emergence of chemical fertilizers has broken through the organic cycle mode of returning crop stalks to the field, which can continuously provide the necessary nutrients for crops, but the long-term use of chemical fertilizers has also caused great damage to the soil. After chemical fertilizers are applied to the soil, only 30% to 40% of the applied amount is absorbed and utilize...

Problems solved by technology

[0002] my country is a big producer of chemical fertilizers and a big consumer of chemical fertilizers. Most of the nutrients in organic fertilizers are absorbed by the soil, and the absorption rate of plants is very low, resulting in soil pollution by nitrates and nitrites, soil compaction, and generation of harmful gases. Seriously damaged, with the rapid development of the chemical industry, the emergence of chemical fertilizers has broken through the organic cycle mode of returning crop stalks to the field, which can continuously provide the necessary nutrients for crops, but the long-term use of chemical fertilizers has also caused great damage to the soil. After chemical fertilizers are applied to the soil, only 30% to 40% of the applied amount is absorbed and utilized by crops, the rest is fixed in the soil, and some migrate out of the soil through volatilization, decomposition, seepage and leaching. .The fertilizer fixed in the soil will pollute the soil environment and affect the soil ecology of the farmland. Therefore, the pollution of the soil by chemical fertilizers and pesticides is another crisis

[0003] At present, people generally use inorganic fertilizers to fertilize stick beans, but long-term use of inorganic fertilizers will cause soil compaction, short fertility time, poor absorption rate of stick beans, and serious impact on the survival of stick beans, resulting in a reduction in the production of stick beans
