Problems solved by technology

Common ways to transform old apple orchards include tree transformation, which treats the symptoms but not the root cause; or uses crop rotation methods such as peanuts, wheat, alfalfa, and potatoes for 1-2 years. Compared with planting apples, the benefits of planting crops are lower. Farmers can't accept

Abstract

The invention relates to an apple replanting obstacle soil conditioner as well as a preparation method and application thereof. Waste trimmed branches in an apple orchard are effectively utilized to be crushed to prepare wood chips, the wood chips are carbonized to prepare biomass carbon, and the biomass carbon is matched with the wood chips, soybean meal and livestock and poultry manure to be fermented; and adding biomass carbides of waste trimmed branches, a microbial agent and marine minerals into a fermentation product to obtain the soil conditioner. An organic matter fermentation product in the soil conditioner can improve the content of organic matters in the apple orchard replanting soil; the biomass carbide enables the soil porosity to be increased, the soil is loosened, the oxygen content is increased, and phlorizin in the soil is degraded; the microbial agent and the marine minerals can balance and regulate the soil micro-ecology, improve the diversity and richness of soil microorganisms, and significantly increase the number of earthworms in the soil. Therefore, the problems of organic matter reduction, soil acidification and soil hardening of old orchard soil are solved, and the purposes of increasing the apple yield and improving the fruit quality are achieved.

Description

technical field [0001] The application relates to the field of agricultural technology, in particular to an apple replanting soil improver and its preparation method and application. Background technique [0002] Our country is rich in all kinds of forest resources, and the agricultural and forestry wastes produced are huge. If the large amount of agricultural and forestry wastes produced every year cannot be properly disposed of, they will become one of the sources of pollution. If these agricultural and forestry wastes are burned on the spot, they will become heat energy. The losses outweigh the gains. Biochar can also be called biomass carbon, which is a solid product obtained by high-temperature pyrolysis of biomass under anoxic or anaerobic conditions. The main characteristics of biochar are high stability, large specific surface area, small bulk density, and rich functional groups. The characteristics determine that biochar has good adsorption properties. Therefore, ...
