【摘要】 １９９２年以来在科尔沁沙地开展的杨树深栽机械化造林试验表明，钻孔深栽植干造林和深松插干造林是一项效率高、成本低、成活率高的造林技术，是一项值得推广，尤其是在半干旱地区推广的技术。杨树植干深栽和深松插干造林在科尔沁沙地需要使用专用设备才能完成，深栽造林钻孔机和深松式插干造林植树机是用于深栽造林的理想和有效设备。使用这两种设备在半干旱沙地和流动沙丘的试验表明，机械化深栽造林技术在治理荒漠化方面有广阔的应用前景。更多还原

【Abstract】 A trial of poplar deep planting using earth auger and medium depth planter had been carried out since 1992. The trial showed a good result of low cost, efficiency and high survival rate. The technology of deep planting should extend to other place of the area especially for semi-arid area. The technology of poplar deep planting needs .special equipment to carry out. The deep planting earth auger and medium depth planter are the practical machines for the technology. Both of them shall extend to all "three north" region especially in Keerqin Sand Area. The trial of afforestation in moving sand dune and semi-arid area using the equipment showed a satisfied future for combating desertification.更多还原
