金沙滩林场研制成功“机引悬挂大苗开沟植树机”。1979年春季植树机样机用于造林,每台植树机一个小时可栽植1—4米高的杨树苗1,000—1,500株。经过5个造林季度实验,共营造杨树、刺槐速生丰产林2,500余亩。实践证明该植树机性能良好,基本上可以满足植苗工艺要求,适用于平原、沙荒、沙地大面积造林和营造农田防护林带。 Jinshatu forest successfully developed “Machine-borne seedlings hanging ditch planting machine.” In the spring of 1979, a prototype of tree planting machine was used for afforestation. Each planting tree machine could plant 1,000-1,500 poplar seedlings of 1 to 4 meters in an hour. After five afforestation quarter experiments, a total of more than 2,500 acres of poplar and acacia fast-growing high yield forest. Practice has proved that the tree planting machine performance is good, can basically meet the requirements of planting seedlings technology, suitable for plain, sand shortage, sandy area afforestation and construction of farmland shelterbelts.
