摘    要:砒砂岩沟坡种植的沙棘人工林,10年后平均树高向2.5~3.0 m趋近,地径近8 cm,沙棘纯盖度在60%、植被总盖度在70%左右.位于当地条件较好沟谷地的沙棘,树高达5 m多、地径在10 cm以上.对于裸岩沟坡来说,目前的10年生沙棘人工林的树高、地径、盖度已接近其生长上限值,特别是沙棘盖度,在超过60%后,应及时平茬...

关 键 词:砒砂岩  沟坡  沙棘  人工林  生长  结实

Abstract:Averaged tree height,ground diameter,pure coverage & total vegetation coverage of H.rhamnoides are respectively nearly 2.5-3.0 m,8 cm,60% & 70% or so after 10 a.In the good site condition like gully bed,the largest height & ground diameter may reach above 5 m & 10 cm.For the naked area of the feldspathic sandstone area,the tree height,ground diameter & coverage of 10 years' H.rhamnoides forest have got to the maximum ones.Especially for the coverage of H.rhamnoides being more than 60%,it is time to stump(th...
