目前我国广大林区在高大的母树林中采种,一般应用绳套或脚踏器上树,既不安全,效率又不高,而且消耗体力大,脚踏器对母树损伤也很严重。为了减轻上树采种作业笨重的体力劳动,我们根据我国种子林的自然条件,研究试验成功了一种小型的 SZ-1型上树升降机具,现介绍如下: At present, the majority of forest areas in our country are planted in tall parent trees. Generally, the tree is used on a sheathed or peddler, which is neither safe nor efficient and consumes great physical strength. The pedaling device damages the mother tree severely. In order to alleviate the cumbersome manual labor of planting seeds on the tree, we have succeeded in researching and experimenting on a small SZ-1 type tree-climbing equipment according to the natural conditions of our country’s seed forests. The introduction is as follows:
