Problems solved by technology

Application of brassinolide at the seedling stage and flowering stage of soybean 4 times can increase the yield by 7~18% (Fan Cuiqin, Li Xiangju, Wang Guiqi, et al. Effect of brassinolide EC on soybean yield and quality[J]. Hebei Agriculture Science, 2005, 9(2): 1-3), but multiple use increases the cost, compounding can reduce the cost

Abstract

The invention discloses a compound growth regulator and a preparation method and application thereof. The compound growth regulator is prepared from the following components in parts by weight: 5-80 parts of trinexapac-ethyl, 4-60 parts of acetylthioproline and 0.001-1 part of brassinolide. According to the compound growth regulator, the coordinated improvement of pod number, grain number and grain weight can be promoted, and numbers of shrunken pods and shrunken grains are significantly reduced; the lodging rate of soybeans is reduced, the yield of the soybeans is increased, and the cost is lowered; the comprehensive quality of soybean seeds and straws is improved, and the content of protein, amino acids (especially methionine, lysine and other essential amino acids) is improved; the drugdamage effect on the soybeans does not exist, and good safety is brought; and the content of pesticide residues in soil can be reduced, and the compound growth regulator is safe to environments.

Description

technical field [0001] The invention relates to the technical field of agricultural growth regulators, in particular to a compound growth regulator and its preparation method and application. Background technique [0002] my country is a major producer of soybeans. Since joining the WTO, due to the negative impact of foreign cheap genetically modified soybean imports, the development space of domestic soybeans has been severely restricted, and the development of soybean processing enterprises is struggling. Competitiveness is of great significance. [0003] 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, 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...
