Water selection mechanism for soybean seed production

ActiveCN224181032UImprove seed production efficiencyReduce work intensitySievingSeed and root treatmentAgricultural scienceAgricultural engineering
The utility model relates to the technical field of soybeans, in particular to a water selection mechanism for soybean seed production, which comprises a fixing frame, a first collecting frame, a second collecting frame, a fixing plate, an electric slide rail, a connecting rod and the like. The interior of the fixing frame is divided into a left cavity and a right cavity, a first collecting frame is slidably connected into the cavity on one side, a second collecting frame is slidably connected into the cavity on the other side, fixing plates are connected to the front side and the rear side of the fixing frame, electric sliding rails are connected to the fixing plates, and connecting rods are connected to sliding blocks of the electric sliding rails. The electric sliding rail, the connecting rod, the scraping plate, the connecting block and the guide block are arranged, according to different floating and sinking characteristics of healthy seeds and poor-quality seeds in water, floating poor-quality soybeans can be fed into the second collecting frame to be collected, the healthy soybeans sink into the water bottom, manual operation is not needed, and the working efficiency is improved. Automatic screening and classification of inferior soybeans and healthy soybeans are achieved, the working intensity of workers is reduced, and the soybean seed production efficiency is improved.

Method for efficiently creating brown glume rice and application thereof

ActiveCN121058552Breduce manufacturing costensure safety
The application belongs to the field of crop genetic breeding, and relates to a method for efficiently creating brown glume rice and application thereof. hcm A stable genetically brown glume mutant is created through radiation mutagenesis, and a molecular marker of the brown glume trait is developed hcm The recurrent parent Huazhan is used as a recurrent parent and the mutant is crossed to create brown glume rice through recurrent selection combined with molecular marker assisted selection. hcm F1 hybrid seeds are obtained by crossing the sterile line Huangling 165S and the brown glume rice, and brown glume hybrid rice seeds can be obtained by planting the F1 hybrid seeds. The brown glume trait of the mutant is introduced into the recurrent parent Huazhan and its hybrid seeds in a targeted manner, and the improved recurrent parent is used to develop hybrid rice seeds. When hybrid rice seeds are produced, the color difference between the seeds of the parents can be used to distinguish hybrid seeds and self-crossed seeds of the recurrent parent, so that the scale mixing, mixed harvesting and color selection separation of hybrid seeds can be realized, and the efficiency of hybrid rice seed production can be improved.
