摘要
在岩溶地区采用墨西哥柏、川滇桤木、清香木、紫花苜蓿等16个树(草)种进行的12种配置模式试验表明:合理的乔灌草配置,有利于长短结合科学经营,前期牧草生长迅速,能很快覆盖地表,减少水土流失,并为牲畜提供大量的饲料,林木长大郁闭度增加后,牧草生长衰退,逐渐转向以经营林木为主。通过综合分析筛选出了适应性强、造林成活率高、生长旺盛、种间共生性良好的优化造林模式8种。
Experiments on combining Cupressus lusitanica etc 16 tree (or grass) species to form 12 forestation modes is summarized. The result shows that reasonable combination of arbors, shrubs and grasses is of benefit to scientific management. In the early planting period, these pasture grasses grow very fast to cover bare ground easily, reduce soil erosion and provide lots of forage. When trees in the site grow up, these pasture grasses grow slowly and main object turns into management timbers. The intergrated analysis shows that 8 optimized forestation modes that are high adaptability, high survival rate, flush growth and friendly accreting among spices had been selected.
