Method for preparing special tea tree fertilizer for improving soil

Abstract

The invention discloses a method for preparing a special tea tree fertilizer for improving soil. The method comprises the following steps: adding urea, triple superphosphate, potassium nitrate, modified calcined kaolin and zeolite powder, uniformly mixing, further adding trace elements, bentonite and turf, adjusting the temperature, uniformly stirring, pelletizing and screening, thereby obtaining the special tea tree fertilizer for improving soil. The method for preparing the special tea tree fertilizer for improving soil, which is disclosed by the invention, is simple, adopts a scientific formula, and is capable of meeting growth requirements of tea leaves, free of topdressing after one time of fertilization, remarkable and long-lasting in fertilizer effect and good in slow-release effect, the yield of tea leaves can be increased, the quality of the tea leaves can be improved, the soil can be improved, and the ecological balance of the soil is improved.

Description

technical field [0001] The invention relates to the technical field of tea tree special fertilizer, in particular to a preparation method of tea tree special fertilizer for soil improvement. Background technique [0002] For young tea trees in the first three years of planting, early rooting and rapid development are the focus of tea farmers' management and protection.
