菌糠预腐解与蚯蚓对苏打盐碱土改良效果的研究
Study on the effect of mushroom residue pre-decomposition and earthworms on improving soda saline-alkali soil
摘要
Abstract
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 saline-alkali 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.关键词
