摘　　要：水湿盐碱地造林技术是重点研究课题之一;华池林区缺乏水湿盐碱地造林技术,影响整流域治理进程。在华池林区选择13个树种,以小叶杨为主开展整地、苗龄、季节、混交等水湿盐碱地造林试验。结果表明,小叶杨、旱柳、沙柳为水湿盐碱地造林适宜树种,生长量与荒山造林相近;水湿盐碱地造林,小叶杨适宜苗龄为4 a,适宜季节为春季,最佳整地方式为排水沟加机械挖穴,沟距4 m,沟宽、深各40 cm,穴直径、深各40 cm;4 a生小叶杨与1 a生沙柳1:1混交,水湿盐碱地造林次春存活效果与荒山相同。上述措施次春存活率均超过90%。Afforestation technology in water-wet saline-alkali land is one of the key research topics.The lack of water-wet saline-alkali afforestation technology in Huachilin area affects the whole watershed management process.In huachilin region,13 tree species were selected to carry out afforestation experiments on water-wet saline-alkali land,including land preparation,seedling age,season and mixing.The results showed that Populus simonii,Salix matsudana and Salix cheilophila were suitable species for afforestation in water-wet saline-alkali land,and their growth was similar to that in barren mountains.For afforestation in water-wet saline-alkali land,the suitable seedling age of Populus simonii is 4 a,the suitable season is spring,and the best land preparation method is drainage ditch and mechanical hole digging,ditch distance is 4 m,ditch width and depth are 40 cm each,hole diameter and depth are 40 cm each.The survival effect of 4 years old Populus simonii and 1 year old Salix cheilophila mixed in 1:1 was the same as that of barren mountain.The survival rate of the above measures was over 90% in the second spring.
