摘    要:对90株毛竹(Phyllostachys heterocycla cv.pubescens)和30条毛竹鞭跳鞭上的冬笋生长特点进行分析。结果显示:①母竹胸径大小与冬笋产量之间的相关性方程为y=63.815x-80.805,R~=0.0802,相关性不显著;②母竹年龄2a的冬笋产量显著高于6a的冬笋产量,t=2.409>t_((29)0.05)2.045,母竹年龄4a的冬笋产量也高于6a的冬笋产量t=2.508 3>t_((29)0.05)2.045,母竹年龄大小对笋产量有显著的影响;③毛竹竹鞭跳鞭上的冬笋数量,来鞭大于去鞭,来鞭上的冬笋占冬笋总产量的71.4%,冬笋生长的范围多数在距母竹100cm以内,占冬笋总产量的68%;④通过母竹找到竹鞭的冬笋,去鞭上的冬笋产量显著高于来鞭上的冬笋产量,来鞭冬笋产量仅占2.62%;⑤随着母竹年龄的增加,冬笋的着生点距离母竹越远,2年生的母竹其冬笋产量、冬笋根数长在100cm以内的达41%,长在200cm以上的只有24%,而6年生的母竹,其冬笋产量、冬笋根数长在100cm以内的仅有14%和18%,长在200cm以上的达46%和42%。

Abstract:Analysis was made on winter shoot growth characteristics of 90 Phyllostachys heterocycla cv.pubescens and 30 rhizomes.The result showed that there was no significant correlation between the DBH of mother bamboo and the yield of winter root(the equation was y = 63.815x - 80.805) from the value of R~2(0.0802).There was significant correlation between mother bamboo age and yield of winter shoot.The yield of winter shoot on 2 and 4-year mother bamboo was greatly higher than that of 6-year one(t = 2.409>t(29)0.0...
