祁连山东端的甘肃省哈溪林区有较大面积的宜林荒山荒坡,其中大多数分布在阳坡。由于降水少、气候干燥、立地条件差,造林成活率普遍较低,所以首选树种便是沙棘,因为沙棘根蘖性强、根系可塑性大、生长迅速,一般5年即可郁闭成林,是优良的薪炭林树种。通过多年生产实践已取得了良好效果,现将具体栽植和管理技术总结如下:一、造林前的准备工作1.要提前做好规划,确定地点、制定措施、组织劳力,落实苗源、提前整地,准确掌握气象信息,雨季造林可大大提高成活率。
There is a large area of barren barren hills and slopes in the northern part of Qixian Mountains in Haxi, Gansu Province, most of which are located on sunny slopes. Because less rainfall, dry climate, poor site conditions, afforestation survival rate is generally low, so the preferred tree species is seabuckthorn, because the seabuckthorn root strong, root plasticity, rapid growth, generally 5 years can be closed forest, is Good firewood tree species. Through years of production practice has achieved good results, the specific planting and management techniques are summarized as follows: First, preparation before reforestation 1. To advance planning, to determine the location, to develop measures to organize labor, implement Miao, advance preparation , Accurately grasp the weather information, rainy season afforestation can greatly improve the survival rate.
