摘要
为探讨撩壕施肥对毛竹林地下鞭系结构的影响,历时10年试验,结果表明:组成竹林地下鞭系结构的竹鞭长度、鞭节数量、鞭段数量、鞭质量、鞭根质量、鞭芽数量,分别比对照竹林增多97.6%、86.2%、74.4%、1.24倍、1.55倍、59.4%;平均节间长、平均鞭段长、平均岔鞭长、平均鞭量、平均鞭根量、平均鞭径、平均鞭芽长度、平均鞭芽粗度,分别比对照竹林增加6.8%、12.9%、13.3%、10.5%、28.9%、8.8%、9.4%、12.1%;幼龄鞭、壮龄鞭、老龄鞭的生长量分别占竹林总生长量的6.3%、66.4%、27.3%。撩壕施肥的竹林其鞭系结构数量和质量均优于对照。
The effect of dugout fertilization on rhizome structure of moso bamboo forest was studied by 10-year trial.The results showed that,the rhizome length,rhizome nodal quantity,rhizome section quantity,rhizome quality,rhizome root quality and rhizome bud quantity compared with the control of bamboo increased 97.6%,86.2%,74.4%,1.24 times,1.55 times and 59.4%respectively.The mean internode length,mean rhizome section length,mean bifurcation rhizome length,mean rhizome quantity,mean rhizome root quantity,mean rhizome diameter,mean rhizome bud length and mean rhizome bud thickness compared with the control of bamboo increased 6.8%,12.9%,13.3%,10.5%,28.9%,8.8%,9.4%and 12.1%.The growth of young rhizome,strong rhizome and old rhizome accounted for 6.3%,66.4%and 27.3%of the total growth of bamboo forest respectively.The quantity and quality of rhizome structure of bamboo forest were superior to the control.
