摘要
对大小年明显的笋竹两用毛竹（Phyllostachys heterocycla cv．pubescens）林地进行覆盖试验，研究覆盖对鞭笋产量和地下竹鞭的鞭径和总鞭长生长的影响。结果表明：在春笋小年的11月，对毛竹林地进行地面覆盖，覆盖45～60d后，覆盖林地鞭笋产量比不覆盖的产量增加2—3倍，达到极显著差异（P值〈0．01）；覆盖挖鞭笋与不覆盖不挖鞭笋之间地下竹鞭总鞭长增加17．4％，平均鞭径粗度增加4．3％；对覆盖的林地通过及时挖除细小鞭的笋，留养和填埋粗壮鞭的笋，弱鞭强挖、壮鞭弱挖，可以解决采用覆盖技术后对毛竹林地的地下总鞭长和幼壮龄鞭的鞭径下降问题。
Experiments were conducted on mulching of Phyllostachys heterocycla cv. pubeseens stands with evident on-off year in Suichang, Zhejiang province from November of 2010. Duration of mulching was about 45-60 days. The result demonstrated that yield of rhizome shoot in mulching stands increased 2-3 times compared with that in the control（no mulching）. Rhizome in stand with treatment of mulching and harvesting rhizome shoot was 17.4% longer and 4.3% larger than that in stand without any treatment. Besides, the stands were needed to remove fine shoot and rhizome, keep and cover large rhizome.
