Description

A kind of tealeaves slowly-releasing organic fertilizer and preparation method thereof

Technical field

The present invention relates to technical field of fertilizers, is a kind of tealeaves slowly-releasing organic fertilizer and preparation method thereof.

Background technology

The used fertilizer type of current tea tree planting is a lot, and wherein the tealeaves special fertilizer adopts the nitrogen-phosphorus-potassium compound fertilizer that can buy on the market mostly, and it mainly is comprised of N, P, K three large inorganic elementss, can satisfy at short notice the growth needs of tea tree.But life-time service can make soil aggregate be destroyed, and easily causes soil compaction, soil property hardening, thereby affects growth of tea plant, and tea leaf quality descends.

Though simple fertilizer is rich in organic matter simultaneously, nutrient discharges slowly, and tea tree absorbs slowly, fertilizer efficiency is low, do not reach active balance between the various available nutrients, because the tealeaves fertilizer formula is science not, causes tea yield not high, chemical composition and micronutrient levels are not high in the tealeaves.
