沙漠治理工作中的植物固沙,是经济、持久并实现改造与利用相结合的最终的有效措施。从造林的角度出发,针对治沙站和社队固沙造林的需要,我们试制了沙丘植树器这种手工工具,曾在治沙现场多次试验,进行了四轮样机的试制、试验和改造,制成SZ-3型和SZ-4型。现简介如下: SZ-3型沙丘植树器由苗木导管、开穴嘴、脚蹬、扶手、投苗筒等组成。开穴嘴由压缩弹簧的作用经常闭合,扶手下有手柄可使开穴嘴开启,调整螺丝调整嘴的开度。苗木导管内装有投苗筒,管外设有控制勾手,投苗筒 Desertification in plant sand fixation, economic, long-lasting and to achieve the transformation and utilization of the final combination of effective measures. From the standpoint of afforestation, in response to the needs of sand control stations and afforestation and afforestation operations, we tried out a hand-made tool such as a sand dune tree-planting device. We experimented many times on the site of sand control and experimented with, prototyped, Made of SZ-3 and SZ-4 type. Now briefings are as follows: SZ-3-type sand dune tree planting by nursery catheters, opening mouth, pedals, handrails, cast seedlings and other components. Opened the mouth by the role of the compression spring is often closed, handrails can be opened under the handle open mouth, adjust the screw to adjust the mouth opening. Nursery catheter tube equipped with throwing seedlings, the control of the hook outside the tube, cast seedling tube
