我省现有天然沙棘林中,老林、密林、干枯死亡的沙棘占有较大的比例,结果量小,经济效益不显著。从采果作业方面讲,由于沙棘林密度较大,大多数结果植株无法得到采收利用,只能使林缘的结果植株遭受不同强度的采收,导致了资源破坏。为了在保护好资源的前提下扩大果实采收范围,提高天然沙棘林的单位面积产量,对部分有条件、有价值的天然林必须进行适当的改造。
The existing natural seabuckthorn in our province, the forest, the jungle, dry seabuckthorn occupy a large proportion, the result is small, the economic efficiency is not significant. In terms of fruit picking operations, most of the resulting plants can not be harvested and harvested due to the high density of seabuckthorn trees, which can only result in different intensities of harvesting of the marginal plant and result in resource destruction. In order to expand the scope of fruit harvesting and improve the yield per unit area of natural seabuckthorn forests under the premise of protecting resources, proper reconstruction of some natural and valuable natural forests must be carried out.
