荒山生态林营造技术研究

Studies on the Technology of Ecological Forests Building in Barren Hill

对济南及鲁南等地区部分荒山的造林情况进行跟踪调查研究,结果显示:在济南地区,无纺布营养杯苗、鱼鳞坑种植、多树种混交在石灰岩荒山造林方面有较好的效果;在鲁南地区,在同种育苗方式下,8个树种的成活率存在显著差异,皂荚和侧柏的成活率最高,而油松和刺槐最低;第1年栽植的侧柏树高、胸径随着苗木规格的增长,生长量逐渐增加,而新梢生长是随着苗木规格的增加,生长量反而下降;通过对两种育苗方式雨季造林的成活率和树高生长量综合评价看,裸根育苗要明显优于基质育苗。

Our work study the afforestation in barren hill of Jinan and Lunan, results showed The adhesive bonded cloth nutrition cup seedling, the scale pit planter, the multi--tree seeds mix hand over have the quite good effect in the limestone barren hill afforestation aspect, the survival rate of 8 species of the existence is significant differences in the same way of seed lings, Gleditsia simcnsis lam and Platycladus oriental is the highest survival rate, but Pinus tabulaeformis Carr. and Amorpha fruticosa L. is the lowest. The tree height and diameter of Platycladus oriental increase with seedling standard growth, but tree top growth reduces with seedling standard growth. Form the survival rate and tree height of afforestation comprehensive evalu- ated by two ways of seedlings in summer, bare root seedlings is better than the matrix seedlings.
