哈密是典型的干旱地区,年降水量不足40mm,水资源严重匮乏,发展沙生灌木树种应受到重视。而沙生灌木树种的育苗一直是我区育苗技术上的一条短腿,近年来,沙生灌木树种主要从吐鲁番、甘肃等地大量调入,年调入量达到1000多万株。一方面由于气候差异,加上远距离的长途运输,致使造林成活率低;另一方面,大量购苗资金外流,难以大规模的进行造林,影响了我区的林业发展。
Hami is a typical arid area with an annual rainfall of less than 40 mm, a serious shortage of water resources and the importance of developing sandy shrub species. The seedlings of Shasheng shrub species has always been a short leg in our area. In recent years, Shashushu shrub species have been transferred in large quantities from Turpan and Gansu provinces, and the annual amount has reached more than 10 million. On the one hand, climate change and long-distance transport over long distances cause low afforestation survival rate. On the other hand, a large number of seedlings and seedlings are out of flow, making it difficult to conduct afforestation on a large scale and affecting the forestry development in our region.
