Embodiment 1

[0022] Dilute the 5% chitosan oligosaccharide solution with water to the corresponding application concentration, the concentration is calculated according to the weight percentage concentration, and is calculated in ppm (parts per million) concentration in the result record, and 50ppm represents the weight percentage in the result record below The concentration is 0.005%.

[0023] The cucumber seeds with plump grains were selected and soaked with chitosan oligosaccharides and distilled water at different dilution times, and soaked in a constant temperature box at 25°C for 24 hours. 30 capsules per treatment, repeated 3 times. Rinse 3 times with distilled water then, be placed in the petri dish that is covered with 3 layers of filter papers, add 10ml distilled water, germinate 10 days under the dark environment in 25 ℃ of incubators, statistically measure root length and plant height.

Embodiment 2

[0027] Embodiment 2: Other crops use chitosan oligosaccharide to promote the experiment of aerial part growth and underground root elongation

[0028] According to the experimental method of embodiment 1, experiment is done respectively to paddy rice, wheat, oat, sorghum, soybean, potato, sweet potato, spinach, celery, Chinese cabbage, rape, cucumber, watermelon and muskmelon, and these crops use chitosan oligosaccharide, including to crop Soak the seeds with chitosan oligosaccharide solution, and spray chitosan oligosaccharide solution at the seedling stage. It is found that when the concentration of chitosan oligosaccharide solution is lower than 25ppm, it will affect the growth of the aboveground part of the crop and the extension of the underground part of the root. Long has a stimulating effect.

Abstract

The invention relates to an application of chitosan oligosaccharide for promoting growth of crop rhizomes, in particular to an application of chitosan oligosaccharide for promoting growth of aboveground plants and growth of root at the growing initial stage of crops, wherein the chitosan oligosaccharide can be dry chitosan oligosaccharide powder, a chitosan oligosaccharide solution or other preparations of chitosan oligosaccharide; and the concentration of the chitosan oligosaccharide solution is 5-25 ppm. The novel application of the chitosan oligosaccharide provides a new direction and method for growth and regulation of the crops, and is beneficial to regulation of the growth of crops by applying a special chemical reagent.

Description

technical field [0001] The invention belongs to the field of agricultural chemistry, and in particular relates to the application of chitosan oligosaccharide in the field of crop growth regulation, in particular to the application of chitosan oligosaccharide to promote the growth of crop roots. Background technique [0002] At present, many substances that can affect the growth of crops have been found, such as hormones, which can affect the growth of crops in a certain way, and some substances, such as nutrients, can provide the necessary material basis for the growth of crops to supplement the soil or The limitation of nutrient deficiency in the air. [0003] For the research on chitosan oligosaccharides, it is generally found that it can promote the growth of crops, but there are few studies on the qualitative promotion of chitosan oligosaccharides. [0004] The present invention unexpectedly finds that the chitosan oligosaccharide has an unexpected effect on the growth ...
