Abstract

The invention discloses a soil improvement method for preventing soil acidification, and the method comprises the following steps: S1, preparation of a primary modifier: S1, preparation of modified diatomite: diatomite is sent into a blasting machine for blasting treatment, blasting is performed for 10-30 s, after blasting is finished, diatomite is sent into an activation solution for activation, and then water washing, centrifugation and drying are performed. In soil improvement, the primary modifier is prepared firstly, the primary modifier is formed by compounding the modified diatomite and the microbial agent, the modified diatomite is exploded and activated through diatomite, so that the surface area and surface energy of the modified diatomite are improved, meanwhile, due to the gap structure of the modified diatomite, the microbial agent is adsorbed, the contact area of the microbial agent and the soil can be increased, and the acting effect of the microbial agent and the soil can be improved; a slow-release effect is achieved through a gap structure, and long-acting modification is achieved.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil improvement method for preventing soil acidification. Background technique [0002] Soil improvement is the process of taking corresponding physical, biological or chemical measures to improve soil properties, improve soil fertility, increase crop yields, and improve the soil environment for human survival, aiming at the poor texture and structure of soil. In the soil conservation stage in the soil improvement process, engineering or biological measures are taken to control the soil loss within the allowable loss range. If soil loss is not controlled, soil improvement cannot be done. For cultivating soil, the first step is to carry out the basic construction of farmland. [0003] The existing soil improvement and acidification prevention method is relatively simple, and the soil quality improvement effect is poor. Based on this, the present invention provides a ...
