Abstract

The invention provides a soil conditioner for improving saline-alkaline soil, and a preparation method and an application thereof, and relates to the technical field of soil conditioners. The soil conditioner for improving the saline-alkaline soil is prepared from, by weight, 60-100 parts of chitosan-sodium alginate composite gel, 5-11 parts of a composite microbial solid inoculant, 20-40 parts ofhumic acid, 5-15 parts of vinegar residues, 0.5-5 parts of an organic acid, 10-30 parts of perlite, 5-20 parts of attapulgite and 5-20 parts of weathered coal. The soil conditioner provided by the invention can effectively reduce the alkalinity and salinization degree of saline-alkaline soil, significantly reduce the pH value of the soil, improve the soil structure and rhizosphere microenvironment, improve the soil fertility and improve the soil remediation capacity, has a long lasting period, and can effectively promote the agricultural and forestry development of saline-alkaline areas.

Description

Technical field [0001] The present invention relates to the technical field of soil amendments, in particular to a soil amendment for improving saline-alkali land, and a preparation method and application thereof. Background technique [0002] Land salinization refers to the degradation process of soil salinization and alkalization caused by the combination of natural factors such as specific climate, hydrology, geology and soil, and improper irrigation and irrigation. The problem of soil salinization is the main factor restricting the sustainable use of agricultural land resources in arid areas, and it is also an important factor affecting the stability of the ecological environment. [0003] Saline-alkali land usually shows alkaline pH, when Na + When too much, the substitutional Na on the soil colloid + With H in solution + Carrying out substitution to produce NaOH to increase the alkalinity of the soil. Strong alkali can make plant root tissue cells rot, and Na + Too much, des...
