Problems solved by technology

The saline-alkali soil conditioner is solid, which solves the shortcomings of liquid soil conditioners that are easy to infiltrate and volatilize. It can effectively improve the state of soil particles and improve soil water retention performance, but the effect is not very satisfactory, and the application range is not very wide. The seedling and production stages of various plants are not practical, and the salinity that has been turned up when encountering water cannot be treated.

Abstract

The invention discloses a saline-alkali soil improving agent and a preparation method thereof. The saline-alkali soil improving agent comprises the following components in parts by weight: 8 to 12 parts of desulfurized gypsum, 30 to 50 parts of biogas residue, 20 to 30 parts of sepiolite ore powder, 10 to 15 parts of oyster shell powder, 5 to 10 parts of phosphate, 3 to 8 parts of humic acid ore powder, 2 to 6 parts of expanded vermiculite powder, 1 to 5 parts of ferrous sulfate, 2 to 4 parts of modified plant straw powder, 0.5 to 1.5 parts of diatomite, 0.4 to 0.8 part of carboxymethyl chitosan, 0.3 to 0.7 part of rotten vinasse, 0.2 to 0.6 part of a microbial preparation and 3 to 7 parts of an organic fermented fertilizer. The saline-alkali soil improving agent can effectively improve the soil structure and reduce the alkalization degree of the soil so as to promote the growth of crops and increase production.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a saline-alkali soil improver and a preparation method thereof. Background technique [0002] Soil salinization is a serious problem affecting global agricultural production and ecological environment, and it is also one of the two major soil factors restricting agricultural production in my country. [0003] The physical and chemical properties of saline-alkali land are poor. Generally, the porosity is small, the soil is easy to compact, and the air permeability and water permeability become poor; the mineralization degree of C and N is low, and the activity of enzymes in the soil is inhibited, which affects the activities of soil microorganisms and The transformation of organic matter reduces the utilization rate of soil nutrients and the content of organic matter, resulting in a decline in soil fertility. Excessive salt ions in the soil can inhibit the reproductive g...
