Abstract

The invention discloses a tobacco strong seedling resistance inducer which is composed of, by mass components, uniconazole, calcium salicylate, diethylaminoethyl hexanoate, sodium nitrophenolate, chitooligosaccharide, Tween, dimethyl sulfoxide, ascorbic acid, prohexadione-calcium, 5-aminolevulinic acid, potassium phosphite, glycine, boric acid, zinc sulfate, copper sulfate, ammonium molybdate, xylitol, and the balance water. By applying the tobacco strong seedling resistance inducer for flue-cured tobacco floating seedling growing production, the low temperature resistance at the seedling stage can be enhanced, the effect of promoting robust growth of tobacco seedlings is achieved, the total root length, the total root surface area, the total root volume of the tobacco seedlings before transplanting are remarkably improved, and the accumulation and root cap ratio of tobacco seedling overground parts and root system dry substances are remarkably improved, the growth of flue-cured tobacco in a field period is promoted, and the tobacco plant biomass and yield and quality after tobacco leaf curing are significantly improved, thereby improving the social and economic benefits of tobaccoproduction.

Description

technical field [0001] The invention relates to the technical field of flue-cured tobacco planting and chemical control, in particular to a tobacco seedling resistance inducer and a preparation method thereof. Background technique [0002] Plant immune inducer is a new field of vaccine engineering technology after human vaccine and animal vaccine, and it is also a popular research direction for the creation of biological pesticides in the world. Plant immune inducers are scientists' practice of scientifically controlling pests and diseases on the basis of revealing the relationship between plants, pests and biological pesticides, and have the effects of significantly improving crop resistance, disease prevention, freezing prevention, yield increase and quality improvement. Harmless and do not pollute the environment. [0003] The principle of action of plant immune inducers: When plants are stimulated by external stimuli or under adverse conditions, they can generate immune...
