Problems solved by technology

[0004] The existing straw decomposing agents have the following defects and deficiencies: (1) The decomposing time is long and the straw decomposing rate is not high; Growth and reproduction will be limited due to changes in environmental conditions such as nutrient composition, pH, and temperature during the decomposition process, resulting in incomplete decomposition; (3) Using the existing method of decomposing straw to improve soil, the reduction of soil bulk density is not obvious, Poor effect of increasing soil porosity and organic matter content and increasing soil aggregate structure

Abstract

The invention provides a Lactobacillus delbrueckii decomposition accelerator, and applications thereof in saline-alkali land straw degradation soil improvement. The Lactobacillus delbrueckii decomposition accelerator is prepared from, 3.2 to 4.6 parts of a compound microorganism powder, 40 to 48 parts of cortex moutan, 20 to 26 parts of Osmanthus fragrans pollen, and 8 to 12 parts of Scenedesmus acuminatus. The compound microorganism powder comprises 50*10<9>CFU / g of Lactobacillus delbrueckii, 60*10<9>CFU / g of Rhodopseudomonas palustris, 28*10<9>CFU / g of monascus purpureus Went, and 36*10<9>CFU / g of Bacillus pumilus. Applications of the Lactobacillus delbrueckii decomposition accelerator in saline-alkali land straw degradation soil improvement comprise steps of decomposition pre-preparation, decomposition of straw with the decomposition accelerator, applying of decomposed straw, and irrigation. In two months of application, soil total porosity ranges from 55 to 57%, and soil bulk density ranges from 1.35 to 1.44g / cm3.

Description

technical field [0001] The invention belongs to the field of soil improvement in saline-alkali land, and relates to a straw decomposing agent, in particular to a Lactobacillus delbrueckii decomposing agent and its application in saline-alkali soil improvement with straw decomposing. Background technique [0002] Coastal saline-alkali land has high soil alkalinity and deteriorated soil physical and chemical properties. The soil swells and becomes muddy when wet, shrinks and hard when dry, and has extremely poor permeability and arable properties. Soil improvement is a key link in greening projects such as seedling planting and special maintenance. [0003] The use of decomposed straw can well improve the outstanding problems of saline-alkali land such as high-salt soil, hard and sticky soil. However, the process of decomposing the straw takes a long time, and if the decomposing is not enough, the plant growth will be affected. Therefore, this method has high requirements for...
