Special fertilizer for tea tree and preparation method thereof

Abstract

The invention discloses a special fertilizer for a tea tree and a preparation method thereof. The special fertilizer is prepared from the following raw materials in parts by weight: 45 to 50 parts ofhuman and animal excreta, 24 to 30 parts of sodium selenite, 16 to 20 parts of corn gluten, 8 to 10 parts of broad been skin, 4 to 6 parts of ammonium molybdate, 2 to 4 parts of potassium fulvic acid,20 to 25 parts of humus soil, 15 to 20 parts of calcium superphosphate, 8 to 10 parts of calcium lignosulphonate, 25 to 30 parts of clay, 6 to 8 parts of potassium metaphosphate, 3 to 5 parts of ferrous sulfate, 6 to 8 parts of sodium bicarbonate and 6 to 8 parts of bacillus subtilis. Compared with the prior art, the special fertilizer for the tea tree has the advantages that the formula is scientific; rich nutrition necessary for the tea tree growth is contained; the growth and the development of the tea tree are effectively promoted; the disease resistance and stress resistance of the tea tree are enhanced; the tea yield is improved; meanwhile, the soil hardening phenomenon is prevented; the tea quality can be improved.

Description

technical field [0001] The invention relates to a special fertilizer for tea trees and a preparation method thereof, belonging to the technical field of fertilizer processing. Background technique [0002] With the long-term and large-scale application of chemical fertilizers to tea tree soil, the physical and chemical properties of most tea tree soil have undergone fundamental changes, mainly manifested in: poor permeability, poor water retention, imbalance of carbon and nitrogen ratio, acidification or alkalization, and decrease in humus content , reduced biological activity, reduced fertilizer utilization rate, and formation of compaction, etc., which have caused a decline in the yield and quality of tea to a certain extent. Therefore, how to improve the soil environment for tea tree planting through reasonable fertilization, so as to improve the quality of tea Purpose is the key problem to be solved urgently in the current tea tree planting industry.
