| 摘 要： | 为了探索贵州大方县半夏种植最佳播种期,为当地及类似生态环境地区发展半夏生产提供理论依据,采用单因素随机区组设计,对不同播期处理半夏的生物学性状和产量性状进行了研究。结果表明:2月末播种的半夏其产量明显高于其他处理;3月上、中旬播种的半夏其10粒重较优;2月末与3月初播种的半夏其块茎病情指数较低。建议:在与大方县羊场镇生态环境类似地区发展半夏生产,播种期选择2月下旬至3月初较为合适。

| Abstract: | The effects of different sowing time on biological traits and yield of P.ternate were studied by the single-factor random block design to probe the optimum sowing time of P.ternate and provide the theoretical basis for production of P.ternate in Dafang County and other areas with the similar ecological environment.The results showed that the yield of P.ternate sowed in the last ten-day period of Feb.was significantly higher than other treatments,100-grain weight of P.ternate sowed in the first ten-day period and middle ten-day period of March was higher than other treatments,and the tuber disease index of P.ternate sowed in the last ten-day period of Feb.and the first ten-day period of March was lower.Therefore,the optimum sowing time for P.ternate is in the last ten-day period and the first ten-day period of March in Dafang County and other areas with the similar ecological environment. |
