摘要
地处黄土高原的陕西省吴起县,是全国沙棘种植面积最大的县,沙棘面积就达12.53万hm2。但随着林龄的增加,林分密度愈来愈大,一是影响结果率;二是容易发生病虫害。所以在沙棘林的抚育管理中应加强沙棘林修剪,促进座果率。对于一般沙棘林,其修剪方法主要包括短截、疏剪、回缩、更新剪(留桩)、徒长枝的修剪等。
The largest county of Hippophae rhamnoides L. cultivation is located in the Loess Plateau, Wuqi County, Shaanxi Province. The cultivation area of Hippophae rhamnoides I.. has reached 180 million mu. However, as the age and density increasing, it is easy to decrease the fruit production and to be suffered by diseases and insect pests. So in the management of Hippophae rhamnoides L. , the pruning should be strengthened to promote the fruiting rate. There are several pruning methods for Hippophae rhamnoides L. forests, namely, heading-back cut, thinning-out cut, shortening cut, renewal cut, watershoot pruning, etc.
