Abstract

The invention discloses a laxogenin and derivative thereof-containing plant growth regulator. The active ingredients of the plant growth regulator comprise one or more than two of the substances shown by the structural formulas in the specifications, wherein the R is F, Cl, Br, I, H, =O, SO4, SOnR2, O-C(O)-R1, O-monosaccharide or polysaccharide, and an N-containing alkaloid structure and salts thereof; and after the plant growth regulator is prepared into solution of the plant growth regulator, the effective final concentration of the laxogenin and the derivative thereof is 0.0001 to 0.5 mg/L. Environmental-friendly laxogenin and derivative thereof are derived from medicinal plant resources, belong to plant source natural metabolic products, and can be absorbed and metabolized by plants, so that the plant growth regulator does not have the adverse effect on the ecological environment and a human health and safety problem and is non-toxic and environmental-friendly technology, meets an environmental-friendly agricultural requirement, has low cost, high stability and a wide application range.

Description

technical field [0001] The invention relates to a plant growth regulator containing laxogenin and its derivatives and its application, which belongs to the field of development and utilization of plant growth regulators, and is specially used in the development of agricultural chemicals, farmland chemical regulation, provenance agriculture, composition cultivation, fruit and vegetable storage, and cut flower insurance. Background technique [0002] The growth and development process of plants is usually regulated by plant endogenous hormones. At the same time, the world's natural disasters are frequent, and the survival of plants is facing serious challenges from various adversity factors: my country has 4 840 km2 of dry and hot valleys caused by high and low temperatures; 640,000 km 2 The Loess Plateau is dry and rainless; 100 million km 2 It is difficult for plants to survive in salinized soil; 173.97 million hm 2 The desertified land is dry, windy and barren; coupled wi...
