以北疆古尔班通古特沙漠东部奇台、吉木萨尔、阜康荒漠区和吐鲁番荒漠区的1,2,5,10 a 树龄梭梭为研究对象,通过梭梭枝条中水分、盐分和养分状况的对比分析,掌握不同荒漠区不同树龄梭梭的水分、盐分和养分特征.结果表明,奇台、吉木萨尔、阜康和吐鲁番荒漠研究区不同树龄梭梭同化枝、2 a 生枝条和多年生枝条中的水分及养分氮素、钾素含量均表现为,随梭梭树龄的增大而减小,且同一树龄梭梭枝条中的水分和养分氮素、钾素含量：同化枝＞2 a 生枝条＞多年生枝条,而不同类型枝条中的盐分和养分磷素含量变化则相反(P ＜0．05).吐鲁番荒漠研究区梭梭同化枝、2 a 生枝条和多年生枝条中的水分和养分磷素含量低于其他研究区,而盐分和养分氮素、钾素含量则高于其他研究区.

The Qitai,Jimusaer and Fukang counties of western Gurbantunggut and Turpan deserts in northern Xinjiang China were used as examples.The characteristics of nutrients,saltinity and moisture con-tents in branches of Haloxylon ammodendron were discussed to reveal the charateristics of moisture,sat-inity and nutrient of Haloxylon ammodendron tree.Results showed that along with the increasing of tree ages,i.e.,1 a,2 a,5 a and 10 a of Haloxylon ammodendron trees in Qitai,Jimusaer,Fukang and Turpan deserts,the contents of N,K and moisture of assimilating shoots,biennial branches and perennial branches all decreased.The moisture and nutrient N,K content in the same tree age Haloxylon ammodendron were as follows:assimilating shoots>biennial branches>perennial branches.However,the content of moisture and nutrient N,K from different branches had contrary changes,there were significant differences between the two.The contents of P and moisture of assimilating shoots,biennial branches and perennial branches in Turpan desert were significantly lower than those of other areas,while the contents of N,K and salinity were significantly higher than those of other areas.
