西黄村大队地处浅山区,有46.3公顷刺槐疏林,均为12年生。因为立地条件较差,经营管理不善,林木生长不良。于1978年冬在林业站的指导下,在第三号小班(双儿坡)对15.05公顷刺槐进行了萌芽更新试验。试验地的立地条件:半阳坡,片麻岩,土层10厘米,坡度10°,植被白草,分布均匀,盖度25％。原造林方法:鱼鳞坑整地,植苗。造林密度167株/亩。伐前(1978年冬)平均高度2.5米,基径10厘米,1978年冬采伐,刨除树疙瘩,不填土(翌年雨季回填)。更新后,1979年冬疏
West Huangcun brigade is located in shallow mountain area, 46.3 hectares of acacia sparse forest, are 12 years old. Because of poor site conditions, poor management, poor growth of trees. In the winter of 1978, under the guidance of the forestry station, 15.05-hectare Robinia pseudoacacia was subjected to a sprouting renewal test in Small Class No. 3 (Shuang’erpo). Site conditions of the experiment: semi-sunny slope, gneiss, soil 10 cm, slope 10 °, vegetation, white grass, evenly distributed, coverage 25%. Original afforestation method: fish scale pit preparation, planting seedlings. Afforestation density of 167 plants / mu. Before cutting (winter 1978) average height of 2.5 m, base diameter of 10 cm, logging in the winter of 1978, tree-lined exclusion, not filling (the next rainy season backfill). After the update, 1979 winter sparse
