Problems solved by technology

At the same time, it contains "chitin" (also known as chitin), which can induce the reproduction of actinomycetes and some other bacteria in the soil, and make it secrete "chitinase", which can antagonize ginseng root disease. , thereby reducing the harm of ginseng root disease; the nutrients contained in a single bone meal are pure, and there is no selectivity for the activation of beneficial microorganisms in the soil, so it cannot fully exert its effect

Abstract

The invention provides a soil regulating agent for old ginseng land which comprises by weight ratio inhibiting agent 0.2-0.5%, actinomycete powder 15-25%, longeron powder 50-70%, calcium magnesium phosphate fertilizer 2-10%, slow release urea 5-15%, potassium sulphate 5-20%, calcium hydroxide 2-5%, trace element 0.1-2.5%. The advantages of the invent includes good applicability, easiness in use, and simplified preparation process.

Description

technical field [0001] The invention relates to soil conditioning, in particular to a soil conditioner for old ginseng soil. Background technique [0002] The reuse of old ginseng land has always been a difficult problem in ginseng cultivation. Under normal circumstances, it takes 7 to 10 years or more to reuse after one crop is planted. The main reasons are soil-borne pathogens, pests, and nutritional deficiencies and imbalances. [0003] Bone meal has long been used in ginseng cultivation at home and abroad, and it can provide nutrients such as phosphorus and calcium for ginseng growth. At the same time, it contains "chitin" (also known as chitin), which can induce the reproduction of actinomycetes and some other bacteria in the soil, and make it secrete "chitinase", which can antagonize ginseng root disease. , thereby reducing the harm of ginseng root disease; the nutrient composition contained in a single bone meal is simple, and there is no selectivity to the activati...
