摘　　要：对阿拉尔地区1a生酸枣实生苗进行实地调查,应用分级确定了2010年1a生酸枣实生苗受冻害情况。结果表明:没浇冬灌水的冻害指数为25.25,浇冬灌水的冻害指数为14.25。9～10月没施氮肥冻害指数只有12,9～10月施氮肥并浇冬灌水冻害指数为32.5。施农家肥的冻害指数为18.25。低洼沟坝地冻害指数高达34.25。表明9～10月不施氮肥、浇冬灌水酸枣实生苗受冻情况轻。In order to provide a basis of grafting and breeding,the field survey of annual wild jujube seedlings in Alar area was conducted and status of frozen injury to annual wild jujube seedlings in 2010 was decided by grading.The results showed that the frozen injury index of irrigating and not irrigating in winter were 14.25 and 25.25,respectively.During 9~10 months,the frozen injury index of not applying N fertilizer was 12,while applying N fertilizer and winter irrigating was 32.5.The index of applying farmyard manure was 18.25.The index of low-lying area reached up to 34.25;Not applying N fertilizer during 9~10 months and irrigating in winter,the wild jujube seedlings were less frozen.
