Special selenium-enriched organic fertilizer of tea and preparation method thereof

Abstract

The invention relates to special selenium-enriched organic fertilizer of tea and a preparation method thereof. The special selenium-enriched organic fertilizer of tea is prepared by mixing a plant selenium source and organic fertilizer, wherein the plant selenium source is prepared from roots and stems of leguminous plants, indigofera tinctoria, hematoxylon, red beans, locust tree branches, kudzu vine, golden peppergrass, isatis tinctoria, arabidopsis and selenium-enriched saccharomycetes through the steps of crushing, fermenting, drying and the like. The organic fertilizer is prepared from the raw materials including pig manure, cattle manure, chicken manure, goose manure, waste tea branches, crop straws and sludge through the steps of crushing and water-logged composting. According to the special selenium-enriched organic fertilizer of tea, the fertilizer is free of chemosynthetic selenium sources and chemical fertilizer, so that the quality of the tea can be ensured; meanwhile, the content of selenium in fresh tea can be increased; the wastes such as the roots, stems and straws of the leguminous plants and the like can be redeveloped and used; the problem of environmental pollution can be reduced; and the production cost of the special selenium-enriched organic fertilizer of tea can also be effectively reduced.

Description

technical field [0001] The invention relates to the field of fertilizer processing, in particular to a special selenium-enriched organic fertilizer for tea and a preparation method thereof. Background technique [0002] At present, the fertilizers used by tea trees are mainly chemical fertilizers containing nitrogen, phosphorus, and potassium elements, in order to increase the nutrition of tea leaves, thereby increasing the yield of tea leaves. However, with the frequent and single use of chemical fertilizers, it will bring adverse effects on the soil environment. In the absence of sufficient organic matter, the soil aggregate structure is difficult to form, the adhesion between soil particles is weakened, and the water retention capacity of the soil is reduced. [0003] In order to solve the problems caused by the long-term use of single chemical fertilizers, organic fertilizers have appeared on the market, that is, microorganisms, such as yeasts, actinomycetes, light and b...

AI Technical Summary

Problems solved by technology

However, the organic fertilizers, formulas and production processes currently on the market are too complicated, and the types and methods of adding bacteria lead to high costs and increase the burden on farmers

[0004] And because the selenium-enriched tea market on the market is relatively good, many tea farmers use a large amount of artificially synthesized chemicals to increase the selenium content of the tea in order to increase the output of the tea, which seriously reduces the quality of the tea and also causes environmental pollution
