摘要
试验采用局部改善植物生长环境的保育基盘法植苗造林技术,对试验地土壤养分特征进行统计分析,确定客土、草炭、珍珠岩和肥料的混合比例(体积比)为5∶3∶1∶1,并探讨保育基盘法植苗造林对苗木成活率、生长的影响。结果表明:有基盘苗木的成活率、苗高和基径生长量较无基盘苗木有显著提高;树种选择的试验结果表明,侧柏、油松的成活率最高,元宝枫次之,栓皮栎成活率最低。
To overcome the low survival rate and slow growth in the rocky mountain areas of Beijing,an afforestation technology by conservation-base was used to improve the local environment of plant growth in the Experimental Forest Farm of Beijing Forestry University.The conservation-base that was made by mixing soil,peat,perlite and fertilizer in the volume ratio of 5∶3∶1∶1 to investigate the impact on the survival rate and growth.Results showed that,the survival rate,seedling height and growth rate in basal diameter increased significantly with the base.Platycladus orientalis and Pinus tabulaeformis had the highest survival rate,Acer truncatum followed,and Quercus variabilis blume the lowest.
