Special composite fertilizer for tea

Abstract

The invention discloses a special compound fertilizer for tea, which consists of the following components: oil tea cake, peanut bran, traditional Chinese medicine residue, humic acid, livestock and poultry manure, biological bacteria preparation, nitrogen, phosphorus and potassium fertilizer, biological insecticide, zinc sulfate , magnesium sulfate, sodium molybdate and superphosphate are prepared according to a certain weight ratio. The invention realizes the organic combination of organic fertilizer, medium and trace elements and quick-acting inorganic fertilizer, and also adds traditional Chinese medicine dregs at the same time, and has the characteristic of combining medicine and fertilizer. The invention has reasonable formula, balanced nutrition, safety and no pollution, fully meets the short-term and long-term nutrient requirements of tea trees, can balance fertilization, improve soil, protect the environment, and can effectively improve the yield and quality of tea.

Description

technical field [0001] The invention relates to a special compound fertilizer for tea and belongs to the technical field of agricultural fertilizers. Background technique [0002] There are many types of fertilizers currently used for tea tree planting, among which the special fertilizer for tea is mostly NPK compound fertilizer available on the market, which is mainly composed of three inorganic elements N, P, and K, which can meet the growth needs of tea trees in a short time. However, long-term use will damage the soil aggregate structure, which will easily cause soil compaction and soil hardening, thereby affecting the growth of tea trees, and the promotion effect on the growth of tea trees is not obvious. [0003] At the same time, although simple organic fertilizers are rich in organic matter, the release of nutrients is slow, the absorption of tea trees is slow, the fertilizer efficiency is low, and effective balance cannot be reached between various effective nutrien...

Problems solved by technology

However, long-term use will destroy the soil aggregate structure, easily cause soil compaction and soil hardening, thus affecting the growth of tea trees, and the promotion effect on the growth of tea trees is not obvious

[0003] At the same time, although pure organic fertilizer is rich in organic matter, it releases nutrients slowly, absorbs slowly from tea trees, and has low fertilizer efficiency. Effective balance of various effective nutrients cannot be achieved
