Embodiment 1

[0035] Embodiment 1 A kind of straw biological decomposing method using anabaena decomposing agent

[0036] (1) Crush the straw

[0037] Mechanically pulverize the sun-dried corn and soybean stalks to 2-3mm particles, wherein the mass ratio of corn stalks and soybean stalks is 2:1.

[0038] (2) Adjust straw C / N ratio and water content

[0039] Adjust the C / N ratio to 35:1; adjust the straw moisture content to 60%.

[0040] (3) Pile up straw

[0041] The crushed straw is stacked in five layers, and the layer weight ratio from bottom to top is 3:3:2:1:1.

[0042] (4) Add Anabaena decomposing agent

[0043] The anabaena decomposing agent prepared by the present invention is uniformly added between straw layers and the uppermost layer, and the decomposing agent is added in 0.55% of the weight of the straw layer.

Abstract

The invention provides a straw biological decomposition method by adoption of an anabaena decomposition accelerator. The method comprises the step of adding the anabaena decomposition accelerator, the anabaena decomposition accelerator is composed of, by mass, 37-49 parts of anabaena, 5-8 parts of complex microbial inoculants, 32-38 parts of cortex ailanthi and 25-29 parts of cushaw flower pollen. According to the straw which is subjected to the decomposition treatment by means of the straw decomposition method, the total carbon content is 27.3-31.2%, the total nitrogen content is 1.86-1.92%, when the decomposition is finished, C / N is 14.2-16.8, T is 0.41-0.48, the total phosphorus content is 0.149-0.164%, and the germination index of seeds can reach 109.5-113.4%; the invention further provides the application of the method in the improvement of saline-alkali soil, by means of the application, the soil salinity and soil pH can be reduced remarkably, the soil porosity can be increased, the soil bulk density can be reduced, the soil water infiltration rate can be enhanced, and the soil fertility can be enhanced.

Description

technical field [0001] The invention relates to a straw decomposing method and its application in saline-alkali soil improvement, in particular to a straw biological decomposing method using anabaena decomposing agent and its application in saline-alkali soil improvement, belonging to the technical field of saline-alkali soil improvement . Background technique [0002] The measures widely used at home and abroad to control saline-alkali land include water conservancy improvement measures (including irrigation, drainage, silt release, rice planting, anti-seepage, etc.), agricultural improvement measures (including land leveling, improved tillage, soil application, fertilization, seeding, crop rotation, etc.) , interplanting, etc.), biological improvement measures (including planting salt-tolerant plants and pastures, green manure, afforestation, etc.) The existing soil improvement methods for saline-alkali land have long improvement cycle, large investment and limited effect...
