Abstract

The invention relates to a fly ash-based shajiang black soil modifier as well as a preparation method and application thereof. The fly ash-based shajiang black soil improver comprises the following raw materials in parts by weight: 45-70 parts of fly ash, 15-25 parts of a humic acid material, 5-10 parts of diatomite, 5-10 parts of zeolite powder, 10-20 parts of livestock manure, 10-20 parts of an active organic material, 5-10 parts of wormcast and 0.5-2 parts of a microbial composite inoculant. The fly ash, the diatomite and the zeolite powder have porous structures, so that the content of clay particles in the shajiang black soil can be reduced, the porosity of the soil is increased, the water permeability and air permeability of the soil are improved, and the physical structure of the soil is improved; the fly ash, the humic acid materials, the animal dung, the wormcast and the active organic materials contain nutrient elements such as N, P and K, so that the nutrient content of the soil can be increased. Compared with the existing biochar modifier, the fly ash-based shajiang black soil modifier provided by the invention has the advantages of low cost, one-time investment and lasting synergism.

Description

technical field [0001] The invention belongs to the technical field of farmland soil improvement and soil fertility improvement, and in particular relates to a fly ash-based sand ginger black soil improver and its preparation method and application. Background technique [0002] Shajiang black soil is widely distributed in Anhui, Henan, Shandong, Jiangsu and other provinces, with an area of ​​about 60 million mu. It is dominated by drought and mainly grows wheat, corn, soybeans and other crops, but the yields are all low. Low-yielding fields. This is because most of the clay minerals in Shajiang black soil are 2:1 type montmorillonite, which has a strong expansion and contraction property. In rainy days, soil particles expand, capillary pores are easily blocked, and water cannot infiltrate in time, causing waterlogging; in drought, The soil particles shrink, the soil cracks and forms large cracks, and the water evaporates from the cracks and leaves the surface, resulting in...
