摘要
毛竹扩鞭试验表明 ,采用土壤管理措施 (锄草松土、深翻垦复、竹蔸施肥及其组合 ) ,可起到促进扩鞭成林的作用 ;锄草松土与深翻垦复 (尤其是深翻垦复 )使单鞭变短 ,鞭段数增加 ,萌动竹笋多 ,新竹株数多 ,退笋率高 ;竹蔸施肥能促进竹鞭的长度生长 ,有利于新鞭、新竹的扩展 ,降低退笋率 ,它们的组合措施则效果更佳。生长上可根据实际要求选择扩鞭促控措施 。
Test on rhizome expanding of Phyllostachys heterocycla cv. pubescens showed that, soil management measures (weeding and loosening the soil, deep plowing, fertilizing in stump of bamboo, and their combination) could enhance the growth of P.heterocycla cv. pubescens to full stand by rhizome expanding. Weeding and loosening the soil, deeping plowing (especially the deeping plowing) could shorten single rhizome, increase the number of rhizome joints, germinating bamboo shoots, the number of new bamboo and the rate of degenerative bamboo shoots. Fertilization in the stump of bamboo could lengthen rhizome joints and is beneficial to the expanding of the rhizome and new bamboo, and lower the rate of degenerative bamboo shoots. Combinative measures could gain better effect on the expanding. Selection of proper measures is needed for best benefit from bamboo stand.
