摘要
在高原城市园林绿化中,利用冬季降温后土壤结冰结冻形成坚硬的冻土层,借鉴和利用工程机械设备切割机,风镐等工具,将大树根系连同冻土层切割成土球,实现了大树冬季切割带土移栽。移栽过程中土球破损率和起挖成本较传统带土移栽法降低了35%和80元/株,成活率和栽植后新梢平均生长量较传统带土移栽法提高了32%和15cm。通过田间试验和技术总结,逐步形成了省力、省工、高效的大树冬季切割带土移栽法。
Tall trees were transplanted in winter with soil balls in plateau cities landscaping, soil balls with roots were made of frozen soil by cutting with cutting machine, pneumatic pick, and so on. The result showed that the breakage rate of soil balls and the cost of transplanting of cutting and transplanting way in win- ter were decreased 35% and 80yuan/palnt compare to traditional transplanting way in spring, the survival rate and branch length of cutting and transplanting way in winter were increased 32% and 15cm compare to tradi- tional transplanting way in spring. Cutting and transplanting way of tall trees in winter with soil was founded by the field test and technology summary, and which is highly active, save time and labor.
