Because soybeans don't bloom and pollinate at high temperature, what medicine can be used for pollination?

Paclobutrazol According to the introduction of the cultivation network, Paclobutrazol is a plant growth retardant, which can hinder the synthesis of growth promoters in plants and inhibit the vertical growth of cells. Therefore, soybean can be pollinated by paclobutrazol because of the high temperature. Soybean (scientific name: soybean (Linn. ) Merr) is a panicum miliaceum of Leguminosae, with a height of 30-90 cm. The protein content of soybean is 35% ~ 40%.
