Abstract:
An experiment showed that the wrinkle percentage of gradlious A
222,A
604 and A
436 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 A
222,A
604 and A
436 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 A
436 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.
