在云南南涧县城后山极度退化山地的治理中,围绕植被恢复而进行的一系列造林技术研究,经6a的试验,现已取得满意结果。树种以原产澳大利亚的桉树类、相思树类以及山毛豆等几种灌木表现较好;采用水平阶整地,配以水平沟、蓄水池(塘)、小拦坝等径流调节措施,可就地“消化”55%以上的径流,提高林木成活率10%~20%;选择适宜的造林方式适时造林;合理组合,科学搭配营造混交林,施肥促长,快速覆盖。在试验区为云南干热地区极度退化山地的治理提供了样板和可行的技术。
In the management of the extremely degraded mountainous hilly area in Nanjian County, Yunnan Province, a series of afforestation techniques conducted around vegetation restoration have been satisfactorily achieved through the experiments of 6a. Species of Australian native species such as Eucalyptus, Acacia and Soybeans and other shrubs performed better; using horizontal leveling, with horizontal ditches, reservoirs (ponds), small dams and other runoff regulation measures can be To “digest” more than 55% of runoff and improve forest survival rate of 10% to 20%; select the appropriate afforestation timely reforestation; reasonable combination of scientific mix to create a mixed forest, promote long-term fertilization and rapid coverage. The experimental area provided a model and feasible technology for the treatment of extremely degraded mountainous areas in dry and hot areas of Yunnan.
