Abstract

The invention discloses a plant growth regulator and application thereof. The plant growth regulator has active components of prohexadione calcium and uniconazole. Experiment show that prohexadione calcium and uniconazole have obvious synergism, so as to realize an ideal anti-lodging effect, eliminate side-effects caused by individual existence, and substantially reduce a usage amount of the active components, environmental pollution, and agricultural cost.

Description

technical field [0001] The invention relates to a plant growth regulator and its application. Background technique [0002] The vigorous growth and lodging of crops such as rice, wheat, corn and soybeans have brought great losses to crop production and limited further increase in yield. [0003] [0004] The general name of prohexadione calcium is prohecadione calcium, and its chemical name is calcium 3,5-dioxo-4-propionylcyclohexanecarboxylate. Contents of the invention [0005] It is an object of the present invention to provide two plant growth regulators. [0006] The active ingredients of the first plant growth regulator provided by the present invention are prohexadione calcium and uniconazole. [0007] In the above-mentioned first plant growth regulator, the mass ratio of the prohexadione calcium and uniconazole is 1:100 to 10:1; preferably 1:10 to 10:1; more specifically 1:1, 4 :1, 1:2, 10:1, 1:4, 5:1, 6:1, 1:9, 1:100 or 1:24. [0008] In the above-mentioned...
