石灰岩山地工程造林技术设计及效果调查

Study on the Technique of Afforestation and Effect at the Stone Quality Hill

通过对徐州市自然条件和16座荒石山立地条件的调查分析,从人工整地、造林树种、苗木规格、造林密度、混交方式、土壤改良、保水保墒、促进生根等,提出了系统的石质山地人工造林技术方案。工程采用15个树种,实际造林470hm2、81万株,总体成活率85.6%,其中侧柏85.8%、龙柏87.5%、女贞93.7%、雪松82.0%、桧柏63.9%、刺槐84.2%、五角枫85.3%、黄连木65.7%、火炬树97.1%、乌桕67.7%、楝树78.1%、柿84.7%、石榴58.6%、枣61.3%、杏40%。不同树种、立地类型和技术措施造林成活率存在差异。

The analyses of site type of the 16 stone investigated. By soil preparation and selection of quality hill of Xuzhou, and the nature condition was planting stock and nursery stock specification and planting density and soil improvement and keep soil humidity and help root fasten a growth. Using 15 tree species, forestation 470hm^2. This methods attained to 85.6% survival rate, Among them, Platycladus orientalis was 85.8%, SabinA chinensis cv. kaizuea was 87. 5%, Ligustrum lucidum was 93.7%, Cedrus deodara was 82.0%, Sabina chinensis was 63.9%, Robinia pseudoaeaeia was 84.2%, Acar mono was 85.3%, Pistacia chinensis was 65.7%, Rhus typhina was 97.1%, Sapiurn sebiferum was 67. 7%, Melia azedaraeh was 78. 1%, Diospyros Kaki var. syivestris was 84. 7%, Ptmica granatum was 58.6%, Zizyphus jujuba was 61.3%, Prunus cerasifera was 40.0% .
