保水剂对新疆克拉玛依砺漠区5种荒漠植物生长和成活率的影响研究

Effect of Super Absorbent Polymers on Growth and Survival Rate of Eremophytes in Karamay Gravel Desert of Sinkiang

以新疆克拉玛依砺漠区5种荒漠植物为研究对象,采用原状土筛分回填的方式进行种植环境的改善,研究保水剂剂量对5种荒漠植物生长和成活率的影响。结果表明:铃铛刺、柠条锦鸡儿最适宜的保水剂剂量为30 g;头状沙拐枣、刚毛柽柳、梭梭3种荒漠植物添加保水剂效果不显著;保水剂剂量为30 g时铃铛刺、柠条锦鸡儿成活率最高,分别为95.6%、91.1%,不添加保水剂时头状沙拐枣、刚毛柽柳、梭梭成活率最高,分别为95.6%、78.9%、93.3%。

This paper studied the effect of super absorbent polymers on growth and survival rate of 5 eremophyte species in Karamay Gravel Desert of Sinkiang and improved the environment of roots by the way of undisturbed soil screening and backfill. The results showed that the optimal dosage of super absorbent polymers was 30 g for Halimodendron halodendron、Caragana korshinskii the survival rates of which were95. 6% 、91. 1% respectively while the effects of super absorbent polymers were not significant for Calligonum caput-medusae、Tamarix hispida and Haloxylon ammodendron the survival rates of which were95. 6% 、78. 9% 、93. 3% respectively without super absorbent polymers.
