Fuente: WIPO "industrial hemp" The utility model provides an industrial hemp breeding pollination isolation device, and belongs to cultivation devices. The industrial hemp breeding pollination isolation device is composed of fixing frames, cross beams and an isolation net cover. The fixing frames are arranged side by side at intervals, the cross beams are fixed to the tops of the adjacent fixing frames at intervals, hanging devices are arranged at fixed points of the fixing frames and the cross beams, and circular rings at the top of the isolation net cover are hung on the hanging devices. The industrial hemp breeding pollination isolation device is reasonable in structural design, good in isolation effect and ventilated, light transmittance is achieved, the yield of industrial hemp fibers is high, and the quality of the industrial hemp fibers is good. The industrial hemp breeding pollination isolation device is simple in structure, convenient to operate, high in stability and suitable for hybridization and selfing of high crops and preservation of variety resources. The arched and n-shaped frames are adopted in the device, the defect that stability is poor due to the fact that an existing device is high is overcome, and meanwhile operation is easy and convenient due to the adoption of N-shaped and M-shaped hooks for hanging operation.
