Chitosan oligosaccharide-contained leaf spraying agent, and production method and use method thereof

Abstract

The invention discloses a chitosan oligosaccharide-contained leaf spraying agent, and a production method and a use method thereof, and provides a formula of the chitosan oligosaccharide-containing leaf spraying agent. The chitosan oligosaccharide-contained leaf spraying agent adopts a water-soluble leaf spraying fertilizer with full nutritive elements is elaborately prepared through reasonable proportions according to the characteristics of nutritive ingredients required by plants, and comprises elements such as N, P, K, Mn, Zn, Fe and Cu, which are required by plant during growth; the elements are existent in the state of ions and convenient to absorb; meanwhile, the elements and chitosan oligosaccharide generate a synergistic effect, so that the elements can be better and effectively absorbed. The formula has the characteristics that the leaf spraying agent can be directly sprayed to different seedling-stage plants, has remarkable effects on plant growth, fruiting rate and the like, and increases the crop yield. The leaf spraying agent can be widely applied to crops such as fruits, vegetables, grains, tea leaves, tobaccos and flowers, and has very good development and utilization values in agriculture.

Description

technical field [0001] The invention relates to agricultural production, in particular to the technical field of production of plant spraying agents. Background technique [0002] Chitosan oligosaccharide, also known as chitin oligosaccharide, scientifically named β-1,4-oligoglucosamine, is a low-molecular-weight product degraded by biotechnology from shrimp and crab shells. Generally, it refers to the collective name of low-polymerized glucosamines with linear or branched chains formed by dehydration condensation of 2 to 10 monosaccharides connected by glycosidic bonds. Compared with chitosan, it has good water solubility and strong function. , High biological activity characteristics. [0003] Chitin oligosaccharides are non-specific signals for plants to recognize the invasion of pathogenic fungi. They show strong immune-inducing activity for many plants, can stimulate the expression of disease-resistant genes in plants, and produce disease-resistant chitinase, chitosana...

AI Technical Summary

Problems solved by technology

[0004] Many plant growth regulator foliar sprays currently in use have the following defects: (1) Plant sprays cannot be used in excess

Increasing the dosage or concentration will not only fail to promote plant growth, but will inhibit its growth, and even lead to deformed leaves, dryness and shedding, and death of the whole plant.

(2) Do not mix at will

For example: ethephon liquid is usually acidic and cannot be mixed with alkaline substances; diethyl hexanoate is easy to decompose in case of alkali and cannot be mixed with alkaline pesticides and fertilizers

(3) Some plant spraying agents cannot be directly dissolved in water. If they are not formulated into the mother liquor in advance and then formulated to the required concentration, the agents are difficult to mix, which will affect the use effect

(4) Traditional plant sprays cannot replace fertilizer application

Generally, growth regulators sprayed on leaves are not plant nutrients, they can only play a role in regulating growth, and cannot replace fertilizers. In the case of insufficient water and fertilizer conditions, spraying too much plant growth regulators will be harmful
