Abstract:

The high loss rate in the rape mechanized harvesting process has restricted the rape production development, and it is difficult to be solved only from the farm machinery aspect. The plant material characteristic research based on mechanized harvesting adaptability was done in this paper. The flowering length, lodging resistance and yield of plant with different density were tested. At the same time the maximum breaking strength was analyzed .The results showed that: the increased appropriately planting density (449800 plant per hm2) was advantageous to the mechanized harvesting, with thinner stem, less branches, upper pod-setting and high stem-lodging resistance. The flowering length of rape was shortened with the increasing of plant density and had little influence on the mechanized harvest work.
