Problems solved by technology

Although the virus-free strawberry seedlings do not contain pathogenic bacteria, they are still vulnerable to pathogenic bacteria in the natural planting process. The seedling plants have insufficient immunity to pathogenic bacteria and are prone to various diseases, which not only leads to the loss of yield and quality. decrease and increase production costs

Abstract

The invention discloses a germ-immune type inductive agent and application thereof and belongs to the technical field of plant immune induction. The germ-immune type inductive agent is characterized in that the germ-immune type inductive agent is prepared from uniformly mixing 34 percent of fructo-oligose, 30 percent of radix astragali polysaccharide, 16 percent of trichoderma, 12 percent of lecithin and 8 percent of bacillus subtilis according to the weight ratio, and 6% germ-immune type inductive agent water solution is sprayed for three times in the strawberry virus-free bottle seedling hardening process, wherein the time interval is 7 days. The germ-immune type inductive agent disclosed by the invention has the advantages that the resistance of strawberry virus-free seedlings to pathogenic bacteria is effectively improved, so that good congenital characters of the strawberry virus-free seedlings are guaranteed. The germ-immune type inductive agent has excellent immunity on xanthomonas campestris, pseudomonas pseudoacaligenes, bacteria erwinia and bacillus pumilus in natural planting and has weak immunity on bacillus and fungi.

Description

technical field [0001] The invention relates to a plant pathogen immunity inducer and its application in strawberry detoxification immunity induction, which belongs to the technique of plant pathogen immunity induction. Background technique [0002] Strawberry is easily infected with various pathogenic bacteria in the process of planting in nature, causing various diseases of strawberry, resulting in plant death and reduced yield. The pathogenic bacteria that are usually susceptible to infection are: Bacillus, Xanthomonas, Pseudomonas, Erwinia, Brevibacterium and fungi. In recent years, detoxification of strawberries has become a mature technology. Although the virus-free strawberry seedlings do not contain pathogenic bacteria, they are still vulnerable to pathogenic bacteria in the natural planting process. The seedling plants have insufficient immunity to pathogenic bacteria and are prone to various diseases, which not only leads to the loss of yield and quality. Decreas...
