摘　　要：竹林地下结构是一个非常复杂的鞭根系统,对河南博爱斑竹（Phyllostachys bambusoides f.lacrima-deaeKeng）林地下鞭系进行调查,结果表明：斑竹地下鞭生长发育和分布存在空间规律性变化,土壤深度对竹鞭的长度有显著影响,鞭龄对鞭径大小影响不显著,对笋芽数的影响达到显著水平。约85.7%的竹鞭分布于0~20 cm土层的土壤中,因此斑竹属于典型的浅根性树种。跳鞭露出地面的部分,竹鞭直径小且节密,无发笋现象,应及时覆土。松土、除草、施肥及适当覆盖有助于竹鞭的生长和笋产量。Rhizome of bamboo has a complex structure.A survey is carried out on rhizome of Phyllostachys bambusoides f.lacrima-deae Keng in Bo＇ai.The result shows that rhizome growth and their distribution in soil are reasonable.The effect of depth of soil on the rhizome length is obvious,whereas the effect of the rhizome age on the rhizome diameter is not obvious,it has a significant effect on the numbers of buds.The bamboo has the typical shallow roots,about 85.7% rhizomes are mainly distributed in 0-20 cm deep soil layer.As for the above rhizome,its diameter is small,length between notes is short,and no shoots grow on it.In order to increase the numbers of rhizome,we should loose the soil,kill the grass,fertilize and cover reasonably.
