为加速石灰岩山地造林绿化步伐,进一步探讨石灰岩瘠薄山地造林的有效技术措施,自1991年开始,我们选用侧柏、刺槐、杏、花椒等苗木和种子进行造林试验。3年营造试验林104.5hm~2,直播造林330hm~2,取得了显著效果。 1 试验地概况 试验区位于嘉祥县城北,属尖山小流域,包括何庙、刘庄、石庄、刘山等4个自然村的荒山丘,海拔45.5～141.3m,
To speed up the pace of afforestation in limestone mountains and to further explore effective measures for afforestation in barren hills of limestone, we started the afforestation experiment with seedlings and seeds of Platycladus orientalis, Robinia pseudoacacia, apricot and Zanthoxylum bungeanum, etc. since 1991. 3 years to create a test forest 104.5hm ~ 2, 330ml ~ 2 live broadcast afforestation, and achieved remarkable results. 1 Experimental Site The experimental site is located in the north of Jiaxiang County. It belongs to the Jianshan Small Watershed and includes 4 natural villages such as Hemiau Temple, Liuzhuang, Shizhuang and Liu Shan. The hills are 45.5 ~ 141.3m above sea level,
