Abstract

The invention belongs to the technical field of pesticide compounding and relates to a plant growth adjustment agent containing chlormequat chloride and chitosan oligosaccharide. The plant growth adjustment agent comprises a component A and a component B, wherein the component A is the chlormequat chloride, and the component B is the chitosan oligosaccharide. The mass ratio of the chlormequat chloride to the chitosan oligosaccharide is 20:(1-10), and the total mass of the chlormequat chloride and the chitosan oligosaccharide accounts for 20-80 percent of the mass of the adjustment agent. The crop growth adjustment agent is compounded of chlormequat chloride and chitosan oligosaccharide and can effectively suppress the excessive growth of crops, improve the nutrient absorption rate of the crops and improve the quality and the mass of a product.

Description

technical field [0001] The invention belongs to the technical field of pesticide compounding, relates to a plant growth regulator, in particular to a plant growth regulator containing chlormequat and chitosan oligosaccharide. Background technique [0002] Leggy refers to the excessive growth of stems and leaves due to uncoordinated growth conditions during the growth of crops and fruit trees. Leggy at the seedling stage means that the seedlings are not short enough, and it also refers to the application of too much nitrogen fertilizer, which makes the plants excessively lush and does not undergo physiological differentiation; It often leads to a decrease in yield, excessive growth of stems and leaves of crops, resulting in tall but fragile branches and leaves that are prone to lodging, consume a large amount of nutrients, affect the reproductive growth of crops, delay crop flowering or less flowering, and then reduce crop yield and quality. [0003] The method of conventiona...
