1 问题的提出造林后,由于种苗的质量不同,栽植的技术不当,或因自然和人畜等因素的影响,难以保证造林植株全部成活,缺苗的现象是不可避免的。辽宁省《造林技术规程实施细则》规定“造林成活率不足85％时,或虽达到85％以上,而呈块状死亡者,要进行补植”。由此可见,补植是造怵工作中的一个重要环节,尤其是对乐用较大株行距的地块,不能缺株,补植更有重要意义。如何抓好补植这一环节,保证造林质量呢?我化曾采用多种方法进行补植,实践中均取得了不同程度的效果。认为利用造林行间栽培补植用苗的方法效果最佳。现仅就这种方法作一小结。
1 Issues raised After afforestation, due to the different quality of seedlings, improper planting techniques, or because of natural and human and other factors, it is difficult to ensure that all afforestation plants survive, the phenomenon of lack of seedlings is inevitable. Liaoning Province “Afforestation Technical Regulations Implementation Rules” provides that “Afforestation survival rate of less than 85%, or although it reached more than 85%, while the block-fatal person, to carry out replanting.” Thus it can be seen that replanting is an important link in the work of making pomfret, especially for those plots with larger spacing for music, which can not be lacking and replanting is more important. How to do a good job planting this link to ensure the quality of afforestation? I have used a variety of methods of replanting, in practice have achieved varying degrees of effect. It is considered that the method of planting replanting seedlings with silviculture line is the best. This method is only a summary.
