Plant growth retardant and preparation method thereof

Abstract

The invention relates to a plant growth retardant and a preparation method thereof, which belongs to the technical field of agriculture. The mepiquat chloride, maleic hydrazide and a nutritional agententer a plant by virtue of a leaf horny layer and are transferred to an active growing part in the plant body and accumulated on top buds to be developed into a plant growth conditioner, and the plant growth conditioner reacts with sulfydryl in the plant body, so that the cell division of differential tissues on the top end of the plant can be inhibited, the top advantages can be damaged, the photosynthesis, the osmotic pressure and the steaming effect can be reduced, the activity of gibberellins in the plant body can be reduced, the cell growth is inhibited, the growth trend of the top bud can be weakened, the longitudinal and transverse growth of the plant can be controlled, the plant internode is shortened, the plant type is compact, the leaf color is dark, the leaf area is reduced, the synthesis of chlorophyll is improved, the vigorous growth of the plant can be prevented, and the growth of the plant can be delayed; and meanwhile, mepiquat chloride can improve the stability of cytomembrane and improve the stress resistance of the plant and does not influence the yield of crops.

Description

technical field [0001] The invention relates to a plant growth retarder and a preparation method thereof, belonging to the field of agricultural technology. Background technique [0002] With the rapid development of cell biology and molecular biology, people began to study the effects of plant growth regulators on plants at the cellular and molecular levels, and the types and quantities of domestic synthetic plant growth regulators also increased rapidly. Plant growth retardants are a class of plant growth regulators commonly used in agricultural production, and have been widely promoted and applied due to their unique advantages. [0003] Compounds that can inhibit the cell division and elongation of lotus meristems while slowing down the growth rate are called plant growth retardants. After the plant growth retardant is applied, the plant body will be dwarfed to a certain extent, but the top meristem of the plant will not be damaged, and the plant development process wil...
