CN-122012245-A - Application of panus funiculosus and VOCs produced by same in promotion of tobacco growth

Abstract

The invention relates to a strain of panus funiculosus and application of VOCs produced by the strain in promoting tobacco growth, and belongs to the technical field of microorganisms. According to the invention, the tobacco is treated by using the Carbon Nano Sol (CNS), and the strain of the panus funiculosus F126 is obtained by separating and screening from tobacco rhizosphere soil, and the strain F126 and VOCs produced by the strain can promote tobacco growth, so that the application of chemical fertilizers in the tobacco is reduced, the ecological environment is further protected, and the sustainable development of agriculture is promoted.

Description

Application of panus funiculosus and VOCs produced by same in promotion of tobacco growth Technical Field The invention relates to a strain of panus funiculosus and application of VOCs produced by the strain in promoting tobacco growth, and belongs to the technical field of microorganisms. Background Tobacco (Nicotiana tabacum l.), a annual herb of the genus nicotiana of the family solanaceae. However, most tobacco areas are continuously planted throughout the year, and the perennial application of chemical fertilizers leads to slow growth, poor resistance and gradually reduced quality and yield of tobacco. In order to promote the growth of tobacco and ensure the yield and quality of tobacco, the existing growth promoting method is to apply a large amount of chemical fertilizer, but the application of the chemical fertilizer in a large amount can cause soil caking to affect the absorption of nutrients by tobacco root systems, and the application of the chemical fertilizer in a large amount has certain influence on ecological environment, grain safety, resource utilization, human health and the like, so that the sustainable development of agriculture is realized, and the problems of reducing the application amount of the chemical fertilizer and improving the utilization rate of the chemical fertilizer are the urgent needs to be solved at present. The utilization of effective measures and related researches for promoting plant growth by plant symbiotic microorganisms in nature has become a new direction of agricultural sustainable development. In natural environment, plants and microorganisms establish a reciprocal symbiotic relationship in the process of dip-dyeing, and the microorganisms can enhance the resistance of host plants to biotic stress and abiotic stress, promote the growth of plants, promote the absorption of nutrients and the like. However, at present, the plant growth promoting bacteria for promoting the growth of tobacco are limited in variety, and the requirement for promoting the rapid growth of tobacco is still difficult to meet. Disclosure of Invention The first object of the present invention is to provide a strain of basket-like bacteria to provide a plant growth promoting bacteria having a function of promoting tobacco growth. A second object of the present invention is to provide the use of the above basket rope for promoting tobacco growth. A third object of the present invention is to provide the use of VOCs produced by the above-described basket bacteria for promoting tobacco growth. In order to achieve the first object, the present invention adopts the following technical scheme: the strain is a strain of panus funiculosus (Talaromyces funiculosus) F126, and the preservation number is CGMCC No.41208. The invention belongs to the pioneering invention, the obtained string basket fungus F126 is separated from tobacco rhizosphere soil, and through the synergistic effect with tobacco, the strain and VOCs produced by the strain can effectively promote tobacco growth, and the strain has the potential of developing into high-efficiency biological bacterial fertilizer, protecting ecological environment and promoting sustainable development of agriculture. In order to achieve the second object, the present invention adopts the following technical scheme: The application of the panus funiculosus in promoting tobacco growth is provided. The strain F126 and tobacco seedlings are co-cultured in a culture dish, the growth condition of the tobacco seedlings in the experimental group is found to be obviously better than that of the control group, the average fresh weight of tobacco plants is increased by 233.3 percent compared with the control group, and the root length and the maximum leaf width are obviously higher than those of the control group (P < 0.05), so that the strain F126 can promote the growth of tobacco. In order to achieve the third object, the present invention adopts the following technical scheme: The VOCs produced by the basket-shaped bacteria are applied to the promotion of tobacco growth. The basket-shaped bacteria F126 and tobacco seedlings are co-cultured under the condition of no physical contact, the growth condition of the tobacco seedlings in the experimental group is found to be better than that of the control group, the average fresh weight of plants is increased by 108.3 percent compared with the control group, and the root length, the maximum leaf width and the maximum leaf length are obviously higher than those of the control group (P < 0.05), so that the VOCs produced by the basket-shaped bacteria F126 can promote the tobacco growth.
