滇中地区栽培唐菖蒲叶焦枯原因初探

Research on Reasons for Leaf Wrinkle of Gradlious hybrids in Central Yunnan Province

  • 摘要: 试验发现滴灌和园土普通棚栽培唐菖蒲"江山美人"(A222)、"苏小娇"(A604)、"嫦娥"(A436)叶焦枯病发生率比法国棚喷灌和苗土条件分别高77%,18%,77%,土壤与大棚交叉试验表明:普通棚种植唐菖蒲"江山美人"、"苏小娇"、"嫦娥"的叶焦枯发生率比法国棚高84%,21%,79%。检测发现法国棚唐菖蒲"苏小娇"叶片所含超氧歧化酶SOD比普通棚高,丙二醛(MDA)含量却比普通棚低。说明土壤离子特性(Ec值,pH值)不是叶焦枯病致病的主导因子,高温、干燥的气候条件才是主要原因。

     

    Abstract: An experiment showed that the wrinkle percentage of gradlious A222,A604 and A436 cultured in plastic green houses with trickle and garden soil was 77,18 and 77 over that of France plastic green houses with sprinkle and seedling soil.The alternative experiments between soil and plastic green house showed that the wrinkle percent of gradious A222,A604 and A436 cultured under plastic green houses with seedling soil was 84,21,79 over that of France plastic green houses with garden soil.The content of SOD abstarted from the leaf of gradious A436 cultivated under France plastic green houses was higher than that of the local plastic plastic green houses,contrarily the content of MDA was lower than that of France plastic green houses.So the iron characteristic of soil(pH,Ec) was not the main reason causing the leaf wrinkle of gradlious,whereas the high temperature and low RH% of air were the major reasons for leaf wrinkle.
