Abstract: For exploring the pod not easy to burst, on the basis of advantages and disadvantages of the existing test method of the strength of rapeseed pod dehiscence, experiment on the strength of different varieties of rapeseed pod dehiscence based on the impending fracturing rape pod method in WDW-type 300 was conducted, and effects of rapeseed varieties, pod size, pod moisture content, pod maturity on the strength of dehiscence were analyzed. The results showed that the load was expressed in a single peak curve with the peak of the strength of rapeseed pod dehiscence as the displacement increased when the loading speed was 10 mm/min. The strength of 28 varieties of rapeseed pod dehiscence was between the range of 0.898-3.035 N. The higher moisture content of the same kind of rape pod, the smaller the strength of rapeseed pod dehiscence when the rapeseed pod is smaller. When the rape pod had significant difference in the size, the strength of rapeseed pod dehiscence increased with the increasing pods size. When the varieties of the rapeseed pod dehiscence is the same, the strength of rapeseed pod dehiscence increased with the increasing moisture. This research provides a new method for measuring the strength of rapeseed pod dehiscence easy and fast.
