Embodiment 1

[0019] The compound microbial agent is composed of a concentration of 5.4×10 7 CFU / ml of Bacillus licheniformis and a concentration of 5.2 x 10 7 The Pseudomonas Zhaotung bacteria of CFU / ml are mixed according to the volume ratio of 2: 1.

[0020] The method for improving the soda saline-alkali land with the composite microbial bacterial agent of the present embodiment is:

[0021] (1) Select a piece of land with a width of 3m and a length of 10m in Zhenlai County, Baicheng City, Jilin Province, with an area of ​​about 30m 2 The typical soda saline-alkali soil has a pH of 10.32 and a salt content of 0.38%. The compound microbial agent is added to the saline-alkali soil at an input rate of 2000ml per square meter;

[0022] (2) After the material is added, the soil is plowed, the plowing depth is 20cm, watered and flooded, and then balanced for a week to reduce the porosity of the soil;

[0023] (3) Soak alfalfa seeds with full granules and complete germs in water for 6 hour...

Embodiment 2

[0036] Choose an area of ​​10m in the soda saline-alkali land 2 In the plot, the compound microbial agent for drench application is composed of a concentration of 1.1×10 6 CFU / ml of Bacillus licheniformis and a concentration of 2.8 x 10 6 CFU / ml of Pseudomonas Zhaotung was mixed according to the volume ratio of 1:0.45. According to the input amount of 2000ml per square meter, the compound microbial agent is added to the saline-alkali soil.

[0037] Application method is the same as embodiment 1.

[0038] The test results are shown in Table 2:

[0039]

Embodiment 3

[0041] Choose an area of ​​10m in the soda saline-alkali land 2 In the plot, the compound microbial agent for drench application is composed of a concentration of 8.7×10 7 CFU / ml of Bacillus licheniformis and a concentration of 4.6 x 10 7 CFU / ml of Pseudomonas Zhaotung was mixed according to the volume ratio of 1:0.55. According to the input amount of 1800ml per square meter, the compound microbial bacterial agent is added to the saline-alkali soil.

[0042] Application method is the same as embodiment 1.

[0043] The monitoring results are shown in Table 3:

Abstract

The invention relates to a composite microbial agent and an application thereof in improving soda saline-alkali soil. The composite microbial inoculum is prepared by mixing bacillus licheniformis witha concentration of 1*10<6>-9*10<7> CFU / ml and pseudomonas zhaodongensis with a concentration of 1*10<6>-9*10<7> CFU / ml according to a volume ratio of 1:(0.45-0.55). The composite microbial inoculum is added into saline-alkali soil according to a usage amount of 1800-2000ml per square meter, and then plowing is performed by 20-30cm for application in improving the saline-alkali soil. The compositemicrobial agent disclosed by the invention is strong in salt tolerance, and can improve high alkalinity, loosen soil structure, reduce viscosity and promote plant growth. In addition, the preparationmethod is convenient, the process is simple and economic, and the composite microbial agent has good popularization and application values.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali soil improvement, in particular to a compound microbial bacterial agent and its application for improving soda saline-alkali soil. Background technique [0002] Soda saline-alkali soil is a type of saline-alkali soil. Soda saline soil contains a large amount of carbonate components, mainly sodium carbonate and sodium bicarbonate. Soda saline soil has a high salt content and a particularly high degree of alkalization, resulting in a high pH of the soil and very poor physical and chemical properties such as structure and permeability, which seriously affect the growth and development of crops. [0003] Saline-alkali land causes idleness and waste of agricultural land resources, hindering the development of agriculture. Saline-alkali land is a huge land resource with extremely high potential value. It is necessary to develop and utilize it reasonably and safely. The improvement of saline-alka...
