A kind of bio-organic fertilizer special for tea tree and its preparation and application method

Abstract

The invention relates to a special bioorganic fertilizer for a tea tree. The special bioorganic fertilizer comprises organic raw materials and auxiliary materials, wherein the organic raw materials comprise 30-40 parts of a food waste, 30-40 parts of earthworm manure, 20-25 parts of turf and 15-20 parts of crop straw; and the auxiliary materials comprise 1 part of potassium dihydrogen phosphate, 1 part of zeolite powder, 1 part of boric sludge and 50-60 parts of water. The preparation method of the special bioorganic fertilizer comprises the following steps: 1, raw material processing: crushing turf to form turf powder, drying, and crushing crop straws to form straw powder; 2, weighing the organic raw materials and the auxiliary materials according to the above weight parts, and uniformly mixing; 3, adding a mixture obtained in step 2 into a fermentation tank; 4, adding ferment bacteria, and fermenting; and 5, drying fermented substances obtained in step 4, crushing, and packaging. The organic fertilizer can be used in the tea tree and other crops, and can improve the soil structure, reduce the consumption of a chemical fertilizer, reduce the pest damage, improve the crop output and improve the quality of agricultural products.

Description

technical field [0001] The invention relates to an organic fertilizer in the field of agriculture, in particular to a special bio-organic fertilizer for tea trees and its preparation and application method. Background technique [0002] In my country's grain production, the nutrient input of chemical fertilizers accounts for about 80-90%, and the nutrient input of organic fertilizers only accounts for 10-20%. However, the amount of organic fertilizer used in developed countries such as Europe, America, and Japan has reached 20% of the total amount of fertilizer used 20 or 30 years ago. 50%, 50% of the use of chemical fertilizers and 50% of organic fertilizers has become an internationally recognized standard for sustainable soil development. The amount of chemical fertilizers used in my country is seriously excessive. The amount of urea used per mu of arable land in my country is more than twice that of the United States, more than three times that of Japan, and more than eig...

Problems solved by technology

The excessive use of chemical fertilizers not only caused a serious decline in soil organic matter, but also caused a series of ecological problems such as soil compaction, salinization, and water eutrophication, which seriously affected my country's food security and ecological security.
