Abstract: The present disclosure relates to the technical field of mineral powder processing, and provides a mineral powder pellet drying device, the device includes a drying box body and a material preparation trough, and shunting buffer assemblies are configured to withstand the impact of falling mineral powder pellets in an elastically concave mode and guide the mineral powder pellets to two sides for dispersion. The device in the present disclosure has a simple structure, and is capable of buffering the impact strength of the falling mineral powder pellets, so that the breakage of the mineral powder pellets caused by a fast falling speed is avoided, therefore, the device in the present disclosure has a better drying effect and is highly applicable.

Abstract: The present invention discloses the use of a flavonoid glycoside and glycosyltransferase gene thereof in regulating plant resistance to weeds. The present invention provides the use of tricin-5-O-glucopyranoside in any one of the following: regulating plant allelopathy; regulating plant resistance to weeds; inhibiting the growth of weeds, and the use of Os07g0503900 protein or related biological materials thereof in any one of the following: regulating plant allelopathy; regulating plant resistance to weeds; regulating the content of tricin-5-O-glucopyranoside in plants; catalyzing the glycosylation of tricin to generate tricin-5-O-glucopyranoside; act as or preparing glycosylation transferase; inhibiting the growth of weeds. The present invention is of great significance for developing environment-friendly green pesticides, cultivating rice varieties with high allelopathy and regulating the biosynthesis of tricin-5-O-glucopyranoside, and provides theoretical guidance for the control of weeds in paddy fields.
