Problems solved by technology

[0004] The existing straw decomposing agents have the following defects and deficiencies: (1) The straw decomposing rate is low and the decomposing cycle is long; (2) The decomposing effect is poor, the total nitrogen content of the straw after decomposing is low, and the organic matter content of the decomposing straw is low. The carbon-to-nitrogen ratio is not ideal; (3) Using the existing method of straw decomposing to improve soil, the soil aggregate structure is small, the soil salt content and soil bulk density are high, and the soil humus content is low

Abstract

The invention provides a streptomyces albus decomposition accelerator and the application thereof in saline-alkali soil straw decay soil condition improvement. The decomposition accelerator comprises 2.2-3.1 parts of compound microorganism bacterial powder, 36-42 parts of Chinese elm barks, 24-29 parts of rose pollen, and 6-11 parts of scenedesmusarcuatus. The compound microorganism bacterial powder comprises 44*109 CFU / g streptomyces albus, 30*109 CFU / g rhodopseudomonas capsulata, 5*109 CFU / g lactobacillus bulgaricus, and 14*109 CFU / g bacillus subtilis. After the decomposition accelerator is adopted in saline-alkali soil straw decay soil condition improvement for a month, the content of salt in a 0-30 cm soil layer is 0.28-0.31%, the pH value of soil is 7.3-7.6, the mean size of the soil granular structure is 3.0-3.5 mm, and the total porosity of soil is 54-59%.

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 Streptomyces albicans decomposing agent and its application in saline-alkali soil improvement with straw decomposing. Background technique [0002] my country's coastal saline-alkali land has a large area and low development utilization rate. Due to seawater erosion and other reasons, the soil colloids in the soil contain a large amount of exchangeable sodium, which increases soil alkalinity and deteriorates soil physical and chemical properties. The soil swells and becomes muddy when wet, and shrinks and hard when dry. , poor permeability and cultivability. Soil improvement is a key link in greening projects such as seedling planting and special maintenance. The use of decomposed straw can well improve the outstanding problems of saline-alkali land such as high-salt soil, hard and sticky soil. [0003] The process...
