| 摘 要： | 通过对深松插干造林技术、钻孔深栽造林和传统造林技术的研究表明 ,深栽比传统造林成活率高 ,生长量大 ,差异显著 ,而且深松插干更适宜科尔沁沙地大面积机械化造林。通过对造林时间、苗木类型及苗木处理研究得出 ,深松插干对造林季节无严格要求 ,二干苗更适宜科尔沁沙地的立地条件 ,但春季造林宜贮苗。对插干露出地面不同高度 ( 0 - 1 0 cm、1 0 - 2 0 cm、2 0 - 3 0 cm、3 0 cm以上 )的研究表明 ,地上部分和地下部分的比例不宜超过 0 .4 ,且幼树在一定的插干小头直径范围内 ,初期生长量随小头直径的增加而增加 ,超过一定范围则二者无多大变化。

| Abstract: | Compared to survival rate and increment between medial deep planting and traditional planting methods,it shows that there is significant difference between survival and increments.On the base,further research that the technology of medial deep planting is suitable for Keerqin sand land.omparison trial about different planting time,different stock type and different treatment had been established.the results are two-year-old stock(n+2) are better than one-year-old stock;if planting in spring,stocks must be buried on underground. It is show about trial of different air height above ground that proportion of upper part (above ground) with bottom part (underground)do not exceed 0.4 |
