Soil conditioner for tea tree

Abstract

The invention provides a soil conditioner for a tea tree, and belongs to the technical field of soil improvements. The conditioner comprises the following components in parts by weight: 2 to 4 parts of chitosan powder, 5 to 8 parts of yeast residues, 15 to 20 parts of sunflower meal, 20 to 30 parts of sea-foam stone powder, 2 to 4 parts of ground phosphate rock, 6 to 10 parts of natural phosphate-potassium ore powder, 3 to 4 parts of powdered borax, 1 to 2 parts of calcium silicate powder, 3 to 4 parts of zinc ore powder, 1 to 2 parts of ferrous sulphate, 1 to 2 parts of magnesium sulphate, 1 to 2 parts of manganese carbonate, and 8 to 12 parts of seaweed fertilizer; the soil conditioner for the tea tree is prepared by mixing the above components; the soil conditioner for the tea tree is applied to the surface of the soil of a tea garden before harvesting every year. Through scientific proportioning, the soil conditioner for the tea tree provided by the invention regulates a micro-ecological environment in the soil, can improve the physical property of the soil and improve the fertilizer retaining capacity and the water retaining capacity, and has a very good improvement effect on acidic soil of the tea garden.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil conditioner for tea trees. Background technique [0002] After long-term planting of tea trees, the soil pH of the tea garden decreases, and the problem of soil acidification is prominent, especially the acidification of the soil surface is very serious. After the tea garden soil is severely acidified, the base ions in the soil gradually leached to the soil layer below the plow layer, causing the deep soil to also face the problem of severe acidification. The main reason for soil acidification in tea gardens is improper fertilization. Since tea trees are ammonium-loving plants, partial application of nitrogen fertilizers in tea garden fertilization management, especially ammonium nitrogen fertilizers and amide nitrogen fertilizers, and ammonium sulfate is a physiologically acidic fertilizer. Long-term use will cause soil pollution. Acidification, urea can be hydr...

AI Technical Summary

Problems solved by technology

After soil acidification, the saturation of soil base decreases, the solubility of aluminum, iron, and manganese increases, and even poisonous, and aluminum and manganese ions can turn phosphoric acid into insoluble salts, reducing the availability of phosphorus. With the decrease of pH, the availability of N, P, K, Ca, Mg, S and other nutrients decreases, which affects the nutrient absorption and growth of tea trees, aggravates the occurrence of diseases and insect pests, and finally affects the economic benefits of tea farmers and brings A series of ecological and environmental issues
