Preparation method of soil remediation agent for cultivation of common morel

Abstract

The invention relates to the field of remediation of soil continuous cropping obstacles, specifically to a preparation method of a soil remediation agent for cultivation of common morel. The soil remediation agent is composed of, by weight, 3-5 parts of diatomite, 2-4 parts of peanut meal, 7-10 parts of a maggot and manure composite material, 6-8 parts of sterile water, 1-2 parts of shell powder, 0.3-0.5 part of dipotassium hydrogen phosphate, 0.3-0.5 part of potassium dihydrogen phosphate, 3-5 parts of an active carbon powder and 0.5-2 parts of slaked lime. The problem of continuous cropping obstacles of soil for cultivation of common morel in the prior art is overcome. According to the invention, bioactivity of soil can be effectively raised, soil micro-ecological composition is regulated, soil structure is improved, soil fertility is raised, nutrition composition of soil is optimized, loss of soil nutrient components is reduced, absorption of heavy metal by crops is decreased, the problem of successive cropping obstacles of soil for cultivation of common morel is solved, and output and quality of common morel are greatly increased.

Description

technical field [0001] The invention relates to the field of repairing soil continuous cropping obstacles, in particular to a preparation method of a soil repairing agent for hickory chick cultivation. Background technique [0002] Obstacles to continuous cropping are a major problem affecting China's current agriculture. Due to the limited amount of arable land, there is little room for land area growth. Many crops have been planted continuously for many years, and it is common that the land is difficult to obtain crop rotation. In addition to industrial pollution, improper use of chemical fertilizers, and soil salinization, obstacles to continuous cropping may occur. The germination of crop seeds and the absorption of water and fertilizer by roots cannot be carried out normally, and the yield and quality of crops have declined, seriously affecting the sustainable development of crop production. The problem of soil continuous cropping obstacles needs to be solved urgently. ...

Problems solved by technology

But in the process of cultivating Morchella, because of the soil continuous cropping barrier, the soil cannot be recycled and reused. We can only gradually eliminate the impact of the soil continuous cropping barrier through other methods, but it often takes a very long time, so the soil is also It has become one of the problems that limit the cultivation scale of hickory chick

[0004] Existing soil remediation agents and other technologies can not effectively improve the soil continuous cropping obstacles used in morel cultivation. For example, the patent CN1141328A soil improvement agent is a kind of inorganic iron ore powder and iron-containing waste. The soil improver that can have a certain growth-promoting effect has no effect on the problem of the soil for hickory chick cultivation; the patent CN1233606A soil nutrient conditioner is a soil conditioner composed of organic peat and inorganic fertilizers, which mainly plays a role in conditioning the soil. and provide nutrients, but the cost of soil for morel cultivation is relatively high and the effect is not significant

Comprehensive analysis of the current technology can be effectively applied to the soil for morel cultivation has not been reported
