摘要
深松插干造林在我国是一种较新的深栽造林作业方式,用于这种造林作业的植树机所能划开的松土沟深度是影响造林成活率的关键。在半干旱的科尔沁沙地腹部,对这种植树机的松土深度与牵引阻力的关系进行了实地测试。取得的数据表明,植树机的牵引阻力随松土深度增大而增大,所做的曲线为一近似直线。进而得出在科尔沁沙地的土壤条件下,使用国产的东方红履带式拖拉机作为植树机的牵引动力,其最大深松作业深度不大于80cm。
The tree planting with inserting the saplings without root into deep loosed soil is a new method in China. The depth of loosed soil ditch that made by planter will be the key for planted tree survival. A test for the relation between ripped ditch depths with its resistance of the planter was carried out in the center region of Kerqin sand. The tested data showed that traction resistance of the planter is increased linear with ripper sinking. The maximum ripped ditch depth of the tree planter is 80cm using domestic made DHF crawler tractor as power in the soil condition of Kerqin sand.
