Problems solved by technology

[0005] Although some achievements have been made in the application of agar oligosaccharides in plant stress resistance, the application of marine oligosaccharides in plant stress resistance preparations in the prior art is still based on fucoidan. About agar oligosaccharides There are relatively few applications, especially no reports of new agar oligosaccharides being used as plant inducers, and the efficacy and broad-spectrum of agar oligosaccharide plant resistance inducers need to be further improved, so as to break the restriction of agar oligosaccharides in Bottlenecks in application of plant resistance inducers

Abstract

The invention discloses a plant resistance inducer containing neoagaro-oligosaccharides, and belongs to the technical field of plant nutrition. The plant resistance inducer comprises the following rawmaterials: neoagaro-oligosaccharides, Bacillus psychrosaccharolyticus and tamarindus polysaccharides, wherein the mass ratio of neoagaro-oligosaccharides to tamarindus polysaccharides is (20 to 40):(5 to 15). According to the plant resistance inducer, neoagaro-oligosaccharides and tamarindus polysaccharides are taken as main components, an efficient plant resistance inducer is prepared through the supplementation with Bacillus psychrosaccharolyticus, the effect of the product is promoted obviously through a synergistic interaction effect among the raw materials, the crop synergistic interaction of crops under the environmental stress conditions of low temperature, drought, salt and alkali and the like can be promoted obviously, and the production increasing capacity under the environmental stress conditions is promoted. The stress resistance effect of the product under the environmental stress conditions of salt and alkali, drought, low temperature and the like is obvious, and the inducer has extremely remarkable effects for field crops such as wheat and rice as well as fruits and vegetables such as cucumber and tomato.

Description

technical field [0001] The invention relates to a plant resistance inducer containing new agar oligosaccharides, in particular to a plant resistance inducer prepared from raw materials such as new agar oligosaccharides, Bacillus cryolyticum, and tamarind polysaccharide, belonging to the technical field of plant nutrition . Background technique [0002] When plants are stressed by external adversities, they can produce a series of reactions such as phytoalexins and antibacterial proteins to resist the adversity. If the plant's defense response to stress is delayed or inhibited, plant growth will be affected. Using inducers to stimulate plants to produce stress-resistant substances, thereby enhancing the resistance of plants to external stress is a new approach to plant protection. Induced by inducers, the stress resistance of plants can be enhanced, the damage caused by adversity stress to plants can be reduced, and some physiological functions can be restored. Oligosaccha...
