Preliminary Test Report on Yield and Oil Content of Rapeseed Zhongyouza 19'After Stem-branch Cutting in Ankang
Rapeseed yield of Zhongyouza 19'was higher in the untreated stem-branch cutting(non-cut-ting)group compared to the cutting group,but the difference was not significant.The oil content of rapeseed in the non-cutting group was significantly higher than that in the cutting group.The average content of oleic acid,linoleic acid,linolenic acid,and palmitic acid in rapeseed of the non-cutting group was higher than that in the cutting group,although the differences were not significant.In this experiment,under the direct seeding cultiva-tion mode,Zhongyouza 19'was harvested for stem-branch cutting in early February according to cutting stand-ards,resulting in 105.083 kg of stems and leaves harvested,a decrease in oil yield of 1.659 kg/667 m2,a de-crease in yield of 1.64％,and a minimal impact on the oil yield of Zhongyouza 19',but an increase in the value of stems and leaves to 1 050.83 yuan.Therefore,according to technical requirements,vigorously promoting the production technology of Zhongyouza 19'as the main oil and vegetable dual-use'will have little effect on the oil yield and economic value of rapeseed.In early February,through the sale of rapeseed stems and leaves,not only can the planting economic benefits of rapeseed be improved and farmers'income increased,but it also meets the consumption needs of consumers for vegetable products during the Chinese Spring Festival.
