| 摘 要： | 为了寻找促进干旱半干旱沙区抗旱造林的新途径,文章在野外自然条件下,对新型抗旱造林产品-"春之霖"固体水进行了应用研究。结果表明,虽然固体水处理后不同苗木不同土层土壤含水量变化不同,但缓慢释放的固体水主要集中在植物根系附近,提高根系层含水量,明显改善苗木的水分状况,减轻水分胁迫。使用固体水的供试苗木成活率均在90%以上,其中沙柳和杨树的成活率分别比对照高于12.5%和14.2%。经固体水处理后的苗木净高生长量、地上生物量、地下生物量均高于对照,固体水附近苗木侧根分布量最多。

| Abstract: | In order to find a new approach on afforestation in arid and semi-arid desert areas,application of a new afforestation product to fight to drought named chun zhi lin dry water was studied.It showed that: Though soil moisture of different seedling trees in different layers was different,dry water releasing slowly mainly collect nearby root systems,which can increase moisture content of root system layer,improve moisture condition of seedling trees,and alleviate water stress;survival rate of tested seedling t... |
