Abstract

The invention belongs to the field of soil improvement, and particularly relates to an active coke-based saline-alkali soil improver and a preparation method thereof. The improver is composed of a porous biological fertilizer and a strain inoculant which are independently packaged, wherein the porous biological fertilizer is obtained by mixing, aging and fermenting an active coke mixture, vinegar residues and chicken manure according to the weight ratio of 1: (0.2-5): (0.2-1); the active coke mixture is obtained by fully mixing active coke screen underflow subjected to homogenization pretreatment and acidification impurity removal with a calcium superphosphate saturated solution and a silicon fertilizer according to the solid weight ratio of 1: (0.5-5): (0.2-1) by utilizing alternating-frequency magnetic coupling ultrasonic grading mechanical stirring; and the strain fungicide is composed of mycorrhizal fungi and a water-retaining agent according to the weight ratio of (0.1-1): (1-5), the mycorrhizal fungi are obtained by compounding glomus mosseae, glomus intraradices and glomus versiforme according to the weight ratio of 1: (0.2-2): (0.5-5) and propagating in local soil, and the inoculated product is a rhizosphere mixture composed of spores, hyphae and mycorrhizal fragments.

Description

technical field [0001] The invention belongs to the field of soil improvement, and in particular relates to an active coke-based saline-alkali soil improver and a preparation method thereof. Background technique [0002] Saline-alkali land contains a large amount of salt segregation, and high content of Na+ can inhibit the plant's response to Ca 2+ 、K + The selective absorption of nutrients, while reducing the absorption of N, P and other nutrients, thus endangering crop growth. In addition, the high pH of saline-alkali soil destroys the soil structure, resulting in easy compaction of the soil, poor air permeability, weak water permeability, and easy loss of water and fertilizer. Saline-alkali land seriously affects crop emergence and grain production. Therefore, it is imminent to improve the saline-alkali land. [0003] Saline-alkali land generally has low fertility and poor structure, which leads to low water and fertilizer retention and air permeability, and difficult...
