Application of chitosan oligosaccharide in improving fruit setting rate

Abstract

The invention relates to an application of chitosan oligosaccharide in improving a fruit setting rate, which is characterized in that the weight percentage of chitosan oligosaccharide in a farm chemical composition containing the chitosan oligosaccharide is 0.004 to 0.0145 percent. The invention also provides a method by utilizing the composition containing the chitosan oligosaccharide to improve the fruit setting rate, which is characterized in that the composition is used for treating crops during different growth periods of the crops, for example the composition is applied at the seedling stage or in the germination period of the crops, in a period before the flowering of the crops, in the flowering period of the crops or in a period after the flowering of the crops or the composition is sequentially applied in the seedling period or the germination period, before the flowering, in the flowering period and after the flowering. The weight percentage of chitosan oligosaccharide in the composition is 0.004 to 0.0145 percent. The chitosan oligosaccharide can effectively improve the fruit setting rate, so that stability in production and income increase of the agriculture can be guaranteed.

Description

technical field [0001] The invention belongs to the field of agricultural chemicals, and in particular relates to an application of chitosan oligosaccharide for improving fruit setting rate. Background technique [0002] The low fruit setting rate of fruit trees has greatly affected the yield and quality of fruits. At present, in order to achieve the purpose of increasing the fruit setting rate, the main measures taken are: correctly grasp the flower bud differentiation time, supply fertilizer and water in time, and remove flowers in a timely and appropriate amount. Pollinator point pollination or use feather duster and other pollinators to lightly dust or rub flowers between different varieties of flowers. Release bees for pollination, implement bee or wall bee assisted pollination, and rationally thin fruit. [0003] The method that usually also takes is to apply plant growth regulator, but the application of plant growth regulator for improving fruit setting rate on frui...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of using plant growth regulators is that on the one hand, the fruit setting rate cannot be effectively improved, and on the other hand, even if the fruit setting rate is increased, the quality of the fruit cannot be guaranteed.

Moreover, the application range of the regulator is relatively narrow, and it can only improve the fruit setting rate for a small number of fruit trees.
