摘要
从苗龄、栽植季节、保水剂处理、根系处理等方面对辽西岩质海岸侧柏造林的栽植技术和成活情况进行了对比试验研究。结果表明：岩质海岸容器苗造林以1．5年生苗龄适宜，同苗龄容器苗造林春、夏、秋三季差异不显著；裸根苗造林前经浸水、带土坨处理可有效提高造林成活率；用保水剂处理裸根苗对提高造林成活率作用明显，保水剂的最佳使用量为200～250g·穴^-1。
Experiment on planting technology and survival ratio of Platycladus orientalis in rocky coast in western Liaoning were conducted by seeding age, planting season, hydrogel treatments, root treaments. The result shows that 1.5-year-old container seeding is suitable to be planted in rocky coast, there is no significant difference in spring, summer and autumn of uniform container seeding. Bare-root seeding with water immersion and take soil balling can enhance survival ratio availably before affoerstation. Using hydrogel to treat bare-root seeding has significant function on improving survival ratio and the optimal dose of hydrogel treatment is 200-250 g per hole.
