Abstract: In order to study the effects of different ecological zones and different varieties of vegetable rape and plucking times on the yield of rape stalk and rapeseed, a completely randomized block design was conducted in Sinan County, Changshun County and Meitan County. The yield of rape stalk and rapeseed under different plucking times and seed harvesting methods and different vegetable rape varieties was measured, and the economic produce value was estimated. The results showed that with the increase of altitude in the planting ecological zones, the yield of rape stalk and rapeseed basically showed a decreasing trend, the interaction effect of different vegetable rape varieties and planting ecological zones and the number of plucking times had a significantly effect on the yield of rape stalk and rapeseed. The yield of rape stalk was significantly correlated with the yield of rapeseed. In the same planting ecological zone, the total yield and economic produce value of Youtai No.6 and Xiziyuan No.1 were higher than those of the other three vegetable rape varieties. The total yield of rape stalk with plucking three times ranged from 574.45 kg/667 m~2 to 1 391.12 kg/667 m~2 in different ecological zones, the yield of rapeseed after plucked rape stalk three times was ranged from 55.59 kg/667 m~2 to 94.44 kg/667 m~2. The yield of rapeseed without pluck rape stalk ranged from 110.00 kg/667 m~2 to 197.14 kg/667 m~2 in different ecological zones, which was 1.53-3.52 times of those after three times of plucking rape stalk.The total economic produce value of different vegetable rape varieties ranged from 2 750.46 yuan/667 m~2 to 6 141.85 yuan/667 m~2 for three times plucked rape stalk+harvested rapeseed in different ecological zones, the economic produce value of rapeseed unpluked rape stalk ranged from 836.00 yuan/667 m~2 to 1 498.26 yuan/667 m~2, the economic produce value of three times plucked rape stalk+harvested seeds was 2.96-6.02 times of those only harvested rapeseed without pluked rape stalk. There was a big difference for the yield of rape stalk and rapeseed and economic produce value of different vegetable rape varieties in different ecological regions. In actual production, it was necessary to select suitable vegetable rape varieties according to different ecological regions.
