不同冬油菜品种抗寒性研究
Study on Cold Tolerance in Different Cultivars of Winter Rapeseed
摘要
Abstract
[ Objective] The experiments were conducted to study the feasibility of expanding winter rapeseed northwards into dry and cold regions in Xinjiang, China by analyzing and comparing resistance against frost and adaptability of the different types and kinds of the winter rapeseeds in these areas. [ Method] The winter - survival rate and agronomic characters, the oil - content, the yield of 10 winter rapeseed were studied and screened.[ Result]The results presented that from the year 2007 to 2010 in northwest China' s Xinjiang Uyghur Autonomous Region, the B. napus cultivars and B. rapa cultivars survived the winter. The growth period was about 280 days,the oil content reached 36 . 77 ％ - 41 .53 ％ , and the yield 2 307 . 44 ～ 3 010 . 07 kg/hm2 . [ Conclusion] As a winter cover crop, it may eliminate a dust source that fumishes the damaging sand storms in Xinjiang China. It is not only possible but also beneficial economically, environmentally and ecologically to grow winter rapeseed in dry and cold regions in Xinjiang, China.关键词
