Embodiment

[0045] 1. Selection of test equipment and materials

[0046] The tobacco variety selected in this experiment is Yun 97;

[0047] Azotobacter strains, potassium solubilizing bacteria strains, phosphate solubilizing bacteria strains and benzoic acid degrading bacteria strains were purchased from Guangzhou Weiyuan Biotechnology Co., Ltd.;

[0048] Tobacco-specific compound fertilizers were purchased from 25kg bagged compound fertilizers produced by Shandong Handa Biotechnology Company;

[0049] Tobacco topdressing, pesticides, sprout inhibitors and fertilization operations are carried out in accordance with the tobacco leaf production operating procedures of Yunnan Tobacco Company;

[0050] The tobacco field is located in the experimental field of a tobacco factory in Honghe, Honghe Prefecture, Yunnan Province. This experimental field is an experimental field for continuous tobacco cropping for 5 years under the same conditions.

[0051]2. Experimental design

Abstract

The invention discloses a microbial agent for inhibiting tobacco continuous cropping obstacles. The microbial agent is prepared by uniformly mixing a nitrogen-fixing bacterium agent, a potassium-dissolving bacterium agent, a phosphorus-dissolving bacterium agent and a benzoic acid degrading bacterium agent according to a ratio of 1:1:1:1, wherein the nitrogen-fixing bacterium agent is a powdery inoculant prepared by culturing azotobacter chroococcum strains, the potassium-dissolving bacterium agent is a powdery inoculant prepared by culturing a bacillus mucilaginosus strain, the phosphorus-dissolving bacterium agent is a powdery mixed inoculant prepared by culturing a pseudomonas strain, and the benzoic acid degrading bacteria bacterium agent is a powdery inoculant prepared by culturing anaspergillus flavus strain. The microbial agent is a composite microbial agent, can quickly recover the problem of soil bacterial colony imbalance caused by tobacco continuous cropping, can improve the allelopathy and autotoxicity of tobacco continuous cropping root exudates on tobacco, and has a better effect of overcoming tobacco continuous cropping obstacles.

Description

technical field [0001] The invention relates to the technical field of tobacco planting, in particular to a microbial agent for suppressing tobacco continuous cropping obstacles. Background technique [0002] Tobacco is one of the important economic crops in our country, attracting many farmers to plant it. Due to the current situation of our country with more people and less land, and the competition of grain, tobacco and land, it has become an obstacle to the production of tobacco in our country. [0003] The microorganisms in the soil are mainly composed of living organisms such as fungi, bacteria, actinomycetes, and algae, and with the change of soil depth and soil-forming environment, the types and quantities of microorganisms in the soil also have significant differences. Soil microorganisms further accelerate the decomposition of organic matter and the migration of nutrients in the soil through physical and chemical reactions such as mineralization, nitrification, am...
