菌糠预腐解与蚯蚓对苏打盐碱土改良效果的研究.

This study uses a large amount of mushroom residue pre-decomposition, and earthworms to improve soda saline-alkali soil rapidly improve soda saline-alkali soil with high addition of mushroom residue and earthworms. It explores the effect of adding a large amount of mushroom residue pre-decomposition and then inoculating earthworms on earthworms in soda saline-alkali soil, as well as the effect of mushroom residue pre-decomposition and earthworms on the distribution of water-stable aggregates, salinization degree, soil nutrients, organic carbon, and water-soluble organic carbon changes in soda saline-alkali soil under the combined action of mushroom residue pre-decomposition and earthworms. The results showed that adding 15%, 20%, 25%, and 30% mushroom residue to soda salinealkali soil for pre-decomposition before inoculation with earthworms can significantly increase the survival rate and daily weight gain of earthworms, resulting in a survival rate of over 90%. Adding 15%-30% mushroom residue for pre-decomposition in soda saline-alkali soil, followed by inoculation with earthworms, significantly increased the number of water stable aggregates >2 mm; Lowered soil pH and increased soil conductivity; Significantly increased the cation exchange capacity in soda saline-alkali soil, with an increase of 4.8-10.2 cmol · kg-1 ; The alkalinity of soda saline-alkali soil was reduced by 2.7-4.0 percentage points, respectively; Significantly increased the content of soil available nitrogen, phosphorus, and potassium, significantly increased the content of soil organic carbon, water-soluble organic carbon, and aromaticity, and significantly promoted the generation of humic acid-like substances. Therefore, a large amount of mushroom residue pre-decomposition and earthworms can quickly and efficiently improve soda saline-alkali soil. [ABSTRACT FROM AUTHOR]
