Abstract
The invention relates to an application of chitosan oligosaccharide in promoting early ripening of crops, which is characterized in that the weight percentage of chitosan oligosaccharide in a composition containing the chitosan oligosaccharide is 0.0025 to 0.0215 percent, preferentially the weight percentage of the chitosan oligosaccharide in the composition is 0.0025 to 0.0155 percent, or preferentially the weight percentage of the chitosan oligosaccharide in the composition is 0.0095 to 0.0215 percent. The chitosan oligosaccharide can effectively promote the early ripening of the crops so as to guarantee the yield stability and income increase of agriculture. On the aspect of promoting the early ripening of the crops, the chitosan oligosaccharide can promote the early ripening of normal crops and also can promote the early ripening of the crops with a vegetation period being delayed because of adverse factors of the nature.
Description
Technical field

Wherein powder injection process is meant that the wind-force that utilizes duster to produce is sprinkling upon the agricultural chemicals of pulvis the surface of crop or controlling object equably; Spray-on process is meant with a certain amount of agricultural chemicals and an amount of water and is made into soup, with the spraying apparatus medicine liquid spray is become droplet, is evenly distributed in crop or controlling object surface; Fumigating system is meant and adopts fumigant or volatile medicament, makes its volatilization become the effectively gas of prevention and elimination of disease and pests; The soil treatment method is meant and takes to spray, dusts, spreads methods such as pesticide-clay mixture, imposes on agricultural chemicals equably in ground or the certain soil layer; The smog method is meant utilizes special-purpose facility to be dispersed into smoke condition to the oily agricultural chemicals, to reach the method for Pesticidal and sterilizing weeding.
Among the present invention, chitosan oligosaccharide is that Glucosamine passes through 1, and the degree of polymerization that the 4-glycosidic bond is formed by connecting is the mixture of the high molecular polymer of 2-30, and mean molecule quantity is 1000-3000 dalton.Chitosan oligosaccharide can be through any means preparation, and for example following method: deacetylation is the mixture of the chitosan oligomer of 2-30 at the shitosan more than 70% through the degree of polymerization that methods such as mechanical degradation method, chemical degradation method, enzyme edman degradation Edman, glycosyl transfer method, composite degradation method prepare.Perhaps, be the mixture of the chitosan oligomer of 2-30 through from fungal cell wall or insect body wall, extracting the degree of polymerization that obtains chitin and prepare through methods such as mechanical degradation method, chemical degradation method, enzyme edman degradation Edman, glycosyl transfer method, composite degradation methods.Perhaps, through passing through 1 by Glucosamine, the degree of polymerization that the chemosynthesis of 4-glycosidic bond is polymerized is the mixture of polymers of 2-30.Chitosan oligosaccharide is the mixture of the high molecular polymer of various polymerization thing at present, that is to say in the chitosan oligosaccharide to be not the oligosaccharides form of the single degree of polymerization, but the chitosan oligosaccharide monose of every kind of degree of polymerization possibly exist all.So no matter prepare through which kind of method; The commercially available prod that perhaps prepares through above-mentioned preparation method, as long as it is that Glucosamine passes through 1, the degree of polymerization that the 4-glycosidic bond is formed by connecting is that 2-30, mean molecule quantity are that the mixture of the daltonian high molecular polymer of 1000-3000 is exactly a chitosan oligosaccharide of the present invention; It can contain acetyl group; But the sugar unit of bonding acetyl group is no more than 40% amount, preferably is no more than 30% amount, especially preferably is no more than 20% amount.Commercially available chitosan oligosaccharide all is the chitosan oligosaccharide product that above-mentioned chitosan oligosaccharide term is set forth basically at present.
In such use and the method, said promotion crop precocity is meant and shortens the ripe time of crop, makes fruit of crop or results object can gather in the crops in advance.
Beneficial effect of the present invention:
The present invention has found that chitosan oligosaccharide can promote crop precocious effectively, guarantees that the stable yields of agricultural increases income.The present invention finds that chitosan oligosaccharide is aspect promotion crop precocity; It can promote the precocity of normal crop; Can also promote because the precocity of the crop growth period retardation that natural unfavorable factor causes; Promote that the scope of precocious crop is wide, seldom crop is had specificity, short precocious and do not influence the output of crop.
Embodiment
In order to understand the present invention, further specify the present invention with embodiment below, but do not limit the present invention.
10wt% chitosan oligosaccharide solution with water is diluted to application corresponding concentration respectively; Concentration is calculated according to weight percent concentration; In outcome record, calculate with ppm (1,000,000/) concentration; What 50ppm represented in the outcome record below is that weight percent concentration is 0.005%, just with 2000 times of 10wt% chitosan oligosaccharide solution dilutions.Clear water is handled as contrast.The area of the crop of experiment is 50 square metres, and each experiment divides 4 groups, averages and calculates various indexs.The condition of clear water control treatment is with the processing of chitosan oligosaccharide, and difference is not contain chitosan oligosaccharide in the clear water that the clear water contrast uses, but amount of application is identical.
Embodiment 1 chitosan oligosaccharide solution is to the short precocious experiment of crop
In to the crop processing procedure, if in a period, handle repeatedly, each is spaced apart 10 days, and with "/" expression at interval, the maturation time of the contrast of handling with clear water compares with the maturation time of the crop of chitosan oligosaccharide processing during expression.Concrete disposition is following:
No matter take which kind of mode to spray chitosan oligosaccharide; Maturing stage to crops such as wheat, paddy rice all shifts to an earlier date, and under the different administration mode, there is difference the time that shifts to an earlier date; Show that various methods of application can both shift to an earlier date the arrival in crop maturing stage, it is longer that whole process is used the time that chitosan oligosaccharide can the ripen in advance phase.
