在太行山石灰岩地区进行了不同造林时间、截干部位、栽植深度、覆盖深度及蘸施抗旱剂等侧柏造林试验。结果表明:侧柏造林阴坡可在3月中旬～4月上旬和7月上旬～8月上旬,阳坡只能在7月上旬～8月上旬;春季和雨季半截造林成活率分别比对照提高25.1％和17.7％;深栽10cm可提高成活率28.5％;三块石覆盖造林可提高成活率29％;蘸施1％抗旱剂可提高成活率11.3％。采用组合配套措施春季以深栽10cm,截干1/2、覆盖三块石可提高成活率22.1％,雨季以深栽10cm、蘸1％抗旱剂、截干1/2可提高成活率16％。利用组合措施造林,可以一次造林成功,无需补植或重造。
In the limestone area of Taihang Mountain, planting experiments such as different afforestation time, truncated stem, depth of planting, depth of cover and drench anti-drought agent were carried out. The results showed that the sunny slopes of Arborvitae afforestation could be from mid-March to early April and early July to early August, and the sunny slope could only be from early July to early August. The survival rates of afforestation in spring and rainy season were higher than those in control 25.1% and 17.7%. Planting 10cm deep can increase the survival rate by 28.5%. Three stone covered afforestation can increase the survival rate by 29%. Dipping with 1% drought resistance agent can improve the survival rate by 11.3%. The combination of supporting measures in the spring to plant 10cm deep, truncated 1/2, covering three stones can increase the survival rate of 22.1%, 10cm deep planting in the rainy season, dipped in 1% of the drought resistance agent, cut 1/2 can increase the survival rate of 16%. Using a combination of measures afforestation, afforestation can be a success, without replanting or reconstruction.
