Abstract

The invention relates to a brassinolide and paclobutrazol compound soybean growth regulator, which comprises the following compositions in percentage by weight: 1-65 percent of active components namely brassinolide and paclobutrazol, and the balance of auxiliaries, wherein the weight ratio of brassinolide to paclobutrazol is 1: 500-1:10,000. In the invention, auxiliaries such as emulsifying agent, solvent, defoaming agent and the like that are commonly used in the pesticide field are adopted to prepare an emulsifiable compound regulator which can be used as a soybean growth regulator for controlling the stem length of soybeans and reducing falling of soybeans. The soybean growth regulator has the advantages of having obvious synergy, achieving intended effect by once application, being capable of effectively controlling the stem length of soybeans and reducing falling of soybeans, wherein the stem length inhibiting rate reaches 13.7-18.7 percent, the falling rate is only one percent, the production of soybeans can be increased by 22.7-29.1 percent, the cost is lowered by 71.07 percent, and the compound soybean growth regulator is safe for the environment.

Description

technical field

[0001] The invention belongs to the field of phytochemical regulation and relates to a plant growth regulator, more specifically, it relates to a brassinolide-paclobutrazol compound soybean growth regulator. Background technique

[0002] Soybean from flowering to pod setting, especially in years with sufficient rainfall, will lead to excessive growth and lodging of plants, affecting inter-row ventilation and light utilization, and ultimately resulting in yield loss. At present, there are two methods for controlling the excessive growth and lodging of soybeans in production. One is manual picking and defoliating, which is labor-intensive and time-consuming and does not meet the requirements of modern agricultural production; Regulators can not only prevent excessive growth of soybeans in years with sufficient rainfall, enhance lodging resistance, but also shape compact plants and regulate soybean vegetative growth and reproductive growth, so they are very popu...
