群加林区为于青海省湟中县最南部,属于黄河流域,平均海拔2750米,年降水量500￣600毫米,地形复杂,呈典型的高山峡谷地貌,自2000年实施天然林保护工程以来,全林区累计完成人工造林5800亩,由于受气候条件、海拔等自然因素的影响,造林成果不显著,随着天然林保护工程,造林任务的逐年加大,为了进一步扩大针叶树种在林区内的覆盖率,保证成活率,巩固造林成果,现将圆柏春季播种实验情况介绍如下:
Qunjialin District is the southernmost part of Langzhong County in Qinghai Province. It belongs to the Yellow River basin with an average elevation of 2750 meters and an annual precipitation of 500 to 600 mm. It has a complex topography and is characterized by typical mountain canyon landscape. Since the implementation of natural forest protection project in 2000 In the whole forest area, a total of 5800 mu of artificial afforestation has been completed. Due to natural factors such as climatic conditions and elevation, the afforestation result is not significant. With the natural forest protection project and afforestation tasks increasing year by year, in order to further expand the coniferous species in the forest Within the coverage, to ensure the survival rate, to consolidate the afforestation results, now Juniper cypress sowing experiments are described below:
