摘　　要：在水富铜锣坝竹产业专业合作社开展绒毛方竹林下种植试验,设计上层乔木不同郁闭度5个小区,分别采用不覆盖地膜和覆盖地膜两种处理,调查种植后3~4个月及12~13个月的成活率,并进行F检验分析。结果表明:不覆盖地膜时,上层乔木郁闭度对短期造林成活率有显著影响;覆盖地膜时,上层乔木郁闭度对短期造林成活率没有显著影响,通过覆盖地膜有助于提高林下种竹的短期造林成活率。是否覆盖地膜,上层乔木郁闭度对1年造林成活率均有显著影响,覆盖地膜虽然有利于提高绒毛方竹短期内的造林成活率,但不利于提高造林1年后的成活率。The undergrowth planting experiment of Chimonobambusa utilis‘Rongmao Fangzhu’was carried out in Shuifu Tongluoba Bamboo Industry Professional Cooperative.Five plots with different canopy densities of upper layer arbors were designed,and two treatments of no mulching and mulching were used respectively.The survival rates of 3 to 4 months after planting and 12 to 13 months after planting were investigated,and F test analysis was carried out.The results showed that the canopy density of upper layer arbors had a significant impact on the survival rate of short-term afforestation when no mulching was used;when covering with plastic film,the canopy density of upper layer arbors had no significant impact on the short-term afforestation survival rate,and covering with plastic film was helpful to improve the short-term afforestation survival rate of planted bamboo under the forest.Whether or not to cover with plastic film,the canopy density of upper layer arbors had a significant impact on the 1-year afforestation survival rate.Although covering with plastic film was conducive to improving the short-term afforestation survival rate of Chimonobambusa utilis‘Rongmao Fangzhu’,not conducive to improving the survival rate of one year after afforestation.
