侧柏是陇东黄土高原区的乡土树种,自然状态下常在险坡、峭壁生长,极耐干旱、瘠薄,是当地干旱山坡、强阳陡坡造林中不可多得的造林树种,也是园林绿化中的常用树种。过去,采用现代育苗技术——容器育苗培育,春夏秋三季均可造林,但成活率高的侧柏容器苗,以前在本地尚无先例。近5年来,我们在甘肃省宁县中村苗圃开展了侧柏容器苗快速培育技术试验,成功培育出870万余株侧柏1年生容器苗,用于荒山造林,成活率高达96%。实践证明,此容器苗快速培育技术,可延长育苗生长期1个月,实现当年育苗,当年造林。现将侧柏容器育苗快速培育及其造林技术总结简述如下。
Platycladus orientalis is the native tree species in Longdong loess plateau. It is often in the state of slope and cliff growth under natural conditions. It is extremely resistant to drought and barren land. It is a rare afforestation species in the afforestation of arid and steep slopes in the local area, as well as in landscaping Common tree species. In the past, the use of modern nursery technology - container nursery nursery, spring, summer and autumn can be afforestation, but the survival rate of arborvitae container seedlings, in the past there is no precedent. In the recent 5 years, we have carried out rapid cultivation experiments of Platycladus orientalis container seedlings in Nakamura nursery, Gansu Province. Successfully cultivated more than 870,000-year-long one-year container seedlings of Platycladus orientalis for afforestation on the barren hills with a survival rate of 96%. Practice has proved that this container seedling rapid cultivation technology, extending seedling growth period of 1 month, to achieve the year seedlings, then afforestation. Now Arborvitae rapid cultivation of container seedlings and afforestation technology summarized as follows.
