摘要
通过对辽西半干旱地区褐土和风沙土上施用保水剂营造小美旱杨和彰武小钻杨试验,结果表明每株施用8g高吸水性树脂保水剂效果最好,可使造林成活率提高30.4-36.4个百分点.
Experiments of silviculturing Populus simonii×(Populus pyramidalis+Salix matsudana)cv.‘Poplaris' and Populus×xiaozhuanica W.Y.Hsu et L.by applying water-retaining agent on cinnamon soil and aeolian sandy soil in semiarid region in western Liaoning Province.Result shows that 8g superabsorbent on per tree can obtain the optimal effect and can increase the survival rate from 30.4%to 36.4%.
