摘要
1999年春在阳泉市郊区的干旱石质阳坡采取吸水剂、根宝、覆石、覆地膜等不同措施进行了元宝枫造林试验。结论 :元宝枫在干石阳坡造林成活情况良好 (在十分干旱的情况下成活率达 79.5% ) ,比油松成活率高 ,但生长量不大 ,1年生苗栽后 1 8个月 ,高生长量仅 7cm(实际是两个生长量 ) ,以后生长情况如何 ,有待进一步观测。在干石阳坡覆膜栽植 ,可提高成活率 1 5%～ 2 0 % ,对树高、地径生长量无明显影响 ;覆石的效果有待进一步试验 ;吸水剂和根宝效果不明显。初步认为元宝枫可在干石阴坡推广 ,而不宜在干石阳坡推广。
Plantation trials of Shantung maple4 were conducte with different measures,water absorption agent,Rood treasure,stone covering,and film covering,in arid and stony sunny slopes of Yanquan subrud in spring of 1999.Chinese pine,but the height increment was only 7 cm at 18 mouts after planting with 1 year old of seedlings.The growth situation from now on shoukd be further observed.Planting with film covering can raise survival rate by 15-20%,and no remarkable effect to height and base diameter increment.Effect of stone covering have to be further tested,and effect of water absorption agent and root treasure haven't been found.The Shantung maple has been considered to be planted in arid and stony shady slops,and not in sunny sloped.
