Problems solved by technology

[0002] The current research focuses on the damage of high temperature stress on the growth of rapeseed at the seedling stage or before the silique stage. There are more and more years of high temperature. The high temperature causes the photosynthetic ability of rape pods to decline, and the organic matter transfer to the seeds is insufficient, which reduces the production of rapeseed or reduces the thousand-grain weight and oil content of the seeds. Many existing formulas mainly reduce high temperature damage. , to reduce the transpiration of water to alleviate the adverse effects of high temperature stress, but it has no effect on the degradation of transplanted chlorophyll

Abstract

The invention belongs to the field of plant growth regulators and provides a regulating agent for regulating high-temperature stress of oilseed rape siliques. The regulating agent is used for alleviating inhibition of high-temperature stress on photosynthesis of oilseed rape siliques. The regulating agent is mainly prepared from sodium selenate, sodium hydrosulfite, salicylic acid, potassium dihydrogen phosphite, brassinolide and water. By the design, the regulating agent for regulating high-temperature stress of the oilseed rape siliques has an effect of increasing the germination rate of autumn oilseed rape in dry land of the Yangtze River Basin. By solution formed by combination of different agents, agents in the regulating agent for regulating high-temperature stress of oilseed rape siliques are capable of activating and improving activity of seed germination related enzymes after soaking of oilseed rape seeds, radicle growth is promoted, and moisture absorption and transporting capacity of seedlings is increased. In addition, the regulating agent for regulating high-temperature stress of oilseed rape siliques is capable of inhibiting disease damages in a seedling stage to guarantee germination quality, and full seedlings in once seeding are realized.
