【摘要】 毛竹笋用林地下鞭根系统的吸收能力是影响竹笋产量的关键因素之一。为充分认识毛竹鞭根系统吸收能力的变化规律 ,达到增产增收的目的 ,对浙江省内较为典型的 3种毛竹笋用林实施根系取样 ,并采用吸附甲烯蓝法进行根系吸收能力的测定。结果表明 :2～ 4年生毛竹根的吸收能力最强 ,随着年龄的增加逐渐转弱。 2年生竹鞭根吸收能力较弱 ,尚处于生长发育阶段 ;3～ 4年生鞭根根系最强壮 ,吸收能力最强 ;5～ 6年生竹鞭开始老化 ,根系吸收能力下降。表 3参 3更多还原

【Abstract】 The absorbing ability of root and rhizome system of  Phyllostachys pubescens shoot forest under the earth is the main factor affecting shoot output.To discover the change rules of the absorbing ability and achieve a high shoot output,the study took the samples of root and rhizome system of Phylloslachys pubescens collected from 3 typical shoot forests in Zhejiang,and measured their absorbing abilities using method of absorbing methylidynel blue.The results show that the absorbing ability of roots aged from 2 to 4 years is the highest,and with the increasing of age,it gets lower.2 year old rhizomes are at the stage of growth and have the low absorbing ability.3 and 4 year old rhizomes are very strong and have the highest absorbing ability.Absorbing ability of 5 and 6 year old rhizomes decreases.更多还原
