Preparation method of soil remediation agent for boletus cultivation

Abstract

The invention relates to the field of soil continuous cropping obstacle repairing, in particular to a preparation method of a soil remediation agent for boletus cultivation. The soil remediation agent comprises components in parts by weight as follows: 3-5 parts of diatomaceous earth, 2-4 parts of peanut meal, 7-10 parts of a maggot manure composite agent, 6-8 parts of sterile water, 0.3-0.5 parts of dipotassium phosphate, 0.3-0.5 parts of monopotassium phosphate, 3-5 parts of activated carbon powder and 0.5-2 parts of slaked lime. The preparation method has the advantages as follows: the problem of soil continuous cropping obstacles for boletus cultivation in the prior art is solved, the biological activity of soil can be improved effectively, micro-ecological composition of the soil is regulated, the soil structure is improved, the soil fertility is improved, the nutritional ingredients of the soil are optimized, loss of the nutritional ingredients of the soil is reduced, heavy metal absorption of crops is reduced, and the yield and the quality of boletus are improved substantially while the problem of the soil continuous cropping obstacles for boletus cultivation is solved.

Description

Technical field [0001] The invention relates to the field of soil continuous cropping obstacle restoration, in particular to a method for preparing a soil restoration agent for boletus cultivation. Background technique [0002] Continuous cropping obstacles are a major problem affecting China's current agriculture. Due to the limited amount of arable land, especially the space for land area growth is scarce. Many crops have been planted continuously for many years, and it is more common for the land to be difficult to rotate and stubble. In addition to industrial pollution, improper use of chemical fertilizers, soil salinization, etc., continuous cropping obstacles may occur. The germination of crop seeds and the absorption of water and fertilizer by roots cannot proceed normally. The yield and quality of crops decline, which seriously affects the sustainable development of crop production. The problem of soil continuous cropping obstacles needs to be solved urgently. Over the y...

Problems solved by technology

However, in the process of cultivating boletus, the soil cannot be recycled due to the obstacle of continuous cropping in the soil. The impact of the obstacle in continuous cropping of the soil can only be gradually eliminated by other means, 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 boletus

[0004] Existing soil remediation agent and other technologies can not effectively improve the soil continuous cropping obstacle problem used in boletus cultivation, such as patent CN1141328A soil improvement agent is a kind of inorganic ir...
