摘    要:用0.62%的保水剂蘸根晒苗6h,油松、侧柏、花椒三个树种苗木成活率达72.5%,而清水处理的成活率仅51.9%;不浸根的成活率41.7%。方差分析表明:用0.62%保水剂处理与清水处理的成活率达显著水平,而它与不浸根的达极显著水平。油松、侧柏、花椒三个树种的成活率中后二者高于前者。抗风干日晒能力,侧柏苗最高,晒6h后栽植成活率汉下降15.8%。油松、花椒苗的成活率下降速度是它的两倍多。

关 键 词:保水剂,造林成活率,苗木含水率,根活力

Abstract:Dipping and sunshinning the seedling roots for 6 hours with the superabsorbent concentration of 0.62%,the survival rates of the seedlings of Chinese pine,oriental arborvitae and Chinese prickly ash were all over 72.5%. However,the survival rates of those seedlings soaked by water superabsorbent were only 51.9%.
Keywords:supprabsorbent  survival rate  water content
