沟壑造林是水土保持的主要措施之一。黄河中游有广阔的荒坡造林地需要绿化,因此造林将是一个异常艰巨的任务,特别是在地广人稀地区,任务显得更加艰巨。为了迅速绿化西北,迅速地大量地培育树苗,解决树苗不足的问题,就必须不断的研究新的造林方法和改进造林技术。西峯水土保持科学试验站曾于1957年在南小河沟试验场进行了杨树台阶压条与灌木直播两种多季造林方法试验,从一年来的试验结果看,已可初步肯定是成功的。它不但可以解决造林苗木不足的问题,同时在造林时间上也大为增多,原来
Gully afforestation is one of the main measures of soil and water conservation. In the middle reaches of the Yellow River, there is a vast shortage of afforested lands that need afforestation. Therefore afforestation will be an extremely arduous task, especially in sparsely populated areas. The task is even more arduous. In order to quickly greening the northwest and quickly cultivating saplings in large numbers and solving the problem of insufficient saplings, it is necessary to constantly study new afforestation methods and improve afforestation techniques. Xifeng Soil and Water Conservation Science Experimental Station In 1957 in South Xiahe Gou test site poplar step and shrub direct seeding two multi-season afforestation method test, from the test results over the past year, may initially be sure to be successful. It can not only solve the problem of insufficient seedlings, but also greatly increase the afforestation time, the original
