Embodiment 1～5

[0041] The preparation of embodiment 1~5 biological bacteria agent 1~5

[0042] The bacterial strains of Bacillus amyloliquefaciens, Pseudomonas fluorescens, and Bacillus pumilus make the biocontrol bacteria agent according to the following steps respectively:

[0043] a. Transplant the strain into a test tube containing LB medium for one-ring activation, and culture at 32°C for 48 hours;

[0044] The formula of LB liquid medium is: tryptone (Tryptone) 10g / L, yeast extract (Yeasextract) 5g / L, sodium chloride (NaCl) 5g / L, pH7.0;

[0045] b. Get a ring of activated bacterial lawn and move it into the LB culture solution described in 600ml of 1000ml Erlenmeyer flask, cultivate it for 72 hours at 120 rpm and 32°C to obtain the fermentation broth;

[0046] c. Inoculate the fermentation liquid into the LB culture liquid at a ratio of 1:200 times of the inoculum, and carry out fermentation culture in the seed tank. The temperature of the seed tank is 32°C. Fermentation seed strains ...

Embodiment 6

[0051] The soil experiment of embodiment 6 biological bacteria agent 1~3

[0052] The composite microbial bacterial agent produced by the method of using embodiments 1~3 carries out field test, test site: the planting area of ​​Yunyan 87 flue-cured tobacco in Mengsa Town, Gengma County, Lincang City, Yunnan Province (99 ° 23 '22 "E, 23°33'40"N).

[0053] The planted species in the test is flue-cured tobacco, and the experimental field for the test is a continuous monoculture of flue-cured tobacco for 12 years, the average soil pH value is 5.30, the soil organic matter content is higher than 30g / kg, and the plot with a high incidence of flue-cured tobacco is spread with organic fertilizer.

[0054] Four treatments were set up in the experiment, namely:

[0055] 1, embodiment 1 gained inoculum 1 (50 times of liquid dips in root / irrigates root);

[0056] 2. The bacterial agent 2 obtained in embodiment 2 (50 times of liquid is dipped in root / irrigated root);

[0057] 3. The bac...

Abstract

The invention discloses a biological microbial inoculum for improving the micro-ecological environment level of tobacco planting soil. The biological microbial inoculum comprises bacillus amyloliquefaciens, pseudomonas fluorescens and bacillus pumilus, wherein the bacillus amyloliquefaciens is a strain with a preservation number of CGMCC No. 6598. The microbial inoculum can improve acidification and organic matter content of long-term tobacco planting soil, and at the same time can play a role in efficiently improving the soil environment.

Description

technical field [0001] The application relates to a biological agent for improving the micro-ecological environment level of tobacco planting soil, which belongs to the field of biological agent formulation. Background technique [0002] If a single species of plant is planted for a period of time, the soil is prone to a series of problems such as acidification, nutritional imbalance, microbial imbalance, decreased water and fertilizer retention capacity, and serious soil-borne diseases caused by continuous cropping obstacles. How to eliminate the above-mentioned problems and ensure the stability and repeatability of soil use is a technical problem that needs to be solved. [0003] For the soil where tobacco plants are continuously planted all year round, problems such as soil acidification and low organic matter content are prone to occur; existing biological bacteria agents cannot effectively and efficiently change the above-mentioned problems existing in the soil. Conte...
