Problems solved by technology

[0002] At present, after planting plants on the soil for a period of time, due to the effect of fertilizers, the soil is easy to compact and harden, and the air permeability of the soil is relatively poor, which is not conducive to the absorption of water by plants. At the same time, if the soil is too loose, it is easy to have diseases and insect pests breeding

Abstract

The invention relates to foamed micropore glass pumice for soil improvement. The foamed micropore glass pumice is characterized by containing foamed micropores, wherein the pore sizes of the foamed micropores are 2-3 mm, the water absorption of the foamed micropores is 30-50%, the strength of the foamed micropores is 2-4 MPa, and the density of the foamed micropores is 0.2-0.3 g / cm<3>; and the foamed micropore glass pumice is prepared through sintering a foamed mixture which comprises the following ingredients in percentage by weight: 85-90% of glass powder, 3-8% of marble powder, 2-5% of silica powder and 2-5% of gypsum powder, wherein the fineness of the glass powder is 40-100 microns, the fineness of the marble powder is 20-40 microns, the fineness of the silica powder is 20-40 microns, and the fineness of the gypsum powder is 20-40 microns. The invention further relates a preparation method of the foamed micropore glass pumice for soil improvement. The foamed micropore glass pumice has the advantages that the hardening of soil can be improved, the water permeability and air permeability of the soil can be improved, and the breeding of pests and diseases can be reduced.

Description

technical field [0001] The invention relates to a foamed microporous glass pumice, in particular to a foamed microporous glass pumice for soil improvement and a preparation method thereof. technical background [0002] At present, after planting plants on the soil for a period of time, due to the effect of fertilizers, the soil is easy to compact and harden, and the air permeability of the soil is relatively poor, which is not conducive to the absorption of water by plants.
