我国沙漠面积约占全国土地面积的13.6％,达130万平方公里。并且,还在扩大。目前沙化现象严重地威胁着我国西北、华北地区的一些重要工程和农业生产。但是,我国的治沙工作仍很落后,尚没有专用有效的治沙机械设备。为了加速治沙工作进程,减少沙害,造福于人类,研究专用的治沙设备是非常必要的。 4ZAG-30型沙生灌木栽植机就是为上述需要研制的一种新型半自功植树机。该样机已于1986年9月11日由林业部科技司主持的技术鉴定会上通过鉴定。该机的研制成功填补了我国流沙地造林机械的空白,处于国内领先水平。目 China’s desert area accounts for about 13.6% of China’s total land area, reaching 1.3 million square kilometers. And, is still expanding. At present, the phenomenon of desertification is a serious threat to some important projects and agricultural production in northwest and north China. However, our country’s sand control work is still laggard, there is no special effective sand control machinery and equipment. In order to speed up the desertification process, reduce the harm of sand and benefit human beings, it is very necessary to study the special sand control equipment. 4ZAG-30 Shasheng shrubs planter is the need for the development of a new type of semi-automatic tree planting machine. The prototype was appraised at a technical appraisal meeting hosted by the Science and Technology Department of the Ministry of Forestry on September 11, 1986. The successful development of this machine has filled the gap of silviculture afforestation machinery in our country and is at the leading level in our country. Head
