摘要
[目的]在威信县开展紫山药浅生槽定向栽培引种试验。[方法]对不同抽样点紫山药块茎产量和部分农艺性状进行了比较。[结果]威信县气候特点适合紫山药生长,产量可达27 900 kg/hm^2。但紫山药仍存在缺塘、分叉、长短粗细不均匀、品相不佳等情况。[结论]该试验为威信县大面积推广种植紫山药提供理论依据。
[Objective] To carry out introduction test on shallow trough directional cultivation of Dioscorea alata L. in Weixin County. [Method]We compared the tuber yield and some agronomic characters of D. alata in different sampling sites. [Result]Weixin County had suitable climate for the growth of D. alata,and its yield reached 27 900 kg/hm^2. However,D. alata had the disadvantages of lack of pool,furcation,uneven length and width,poor state of preservation and so on. [Conclusion]This research provided theoretical foundation for the large scale extension of D. alata in Weixin County.
