Tea tree improving fertilizer

Abstract

The invention discloses a tea tree improving fertilizer which consists of the following raw materials in parts by weight: 50-70 parts of composted cow dung, 20-30 parts of nitrogen-phosphorus-potassium fertilizer, 15-20 parts of ground phosphate rock, 10-12 parts of ground potassium rock, 5-7 parts of Chinese wax gourd peel, 2-4 parts of oyster shell powder, 5-7 parts of sweet potato stems, 3-5 parts of herba leonuri, 6-8 parts of fructus cnidii particles, 10-15 parts of soil conditioner, 4-6 parts of EM microbial agent, 1-2 parts of sodium selenite, 2-4 parts of ammonium polyphosphate, 1-3 parts of calcium superphosphate and 2-3 parts of zinc sulfate. With high nutrient content, the fertilizer disclosed by the invention improves the soil fertility and tea quality and has a perfect economic value; meanwhile, activated carbon in the soil conditioner has relatively strong adsorbability and effectively adsorbs pollutants such as heavy metals in the soil so as to effectively green the soil and reduce harm to the plants; and moreover, chitosan is a bioactive macromolecule, and through combination with soy isolate protein, the water absorption and water retention of the soil can be effectively realized, the water content of the soil is guaranteed, and the soil properties are improved comprehensively.

Description

technical field [0001] The invention relates to an organic fertilizer, in particular to a tea tree improvement fertilizer. Background technique [0002] Most of the special fertilizers for tea use the nitrogen, phosphorus and potassium compound fertilizers available on the market, which are mainly composed of three inorganic elements N, P, and K, which can meet the growth needs of tea trees in a short time; but long-term use will damage the soil aggregate structure. If it is damaged, it will easily cause soil compaction and soil hardening, which will affect the growth of tea trees and reduce the quality of tea leaves; at the same time, although simple organic fertilizers are rich in organic matter, they release nutrients slowly, slow absorption by tea trees, and low fertilizer efficiency. Without an effective balance, due to the unscientific formula of tea fertilizer, the yield of tea is not high, and the content of chemical components and trace elements in tea is not high...
