毛竹不同繁殖材料造林效果分析

通过对竹蔸、竹鞭、无鞭母竹、有鞭母竹等繁殖材料形成林分5年的观测，结果表明：有鞭母竹成活率、出笋率、长竹率、新竹生长等指标较好，但造林成本较高，竹蔸造林其次，无鞭母竹造林虽成活，但不长竹。综合考虑，选择毛竹繁殖材料的次序为有鞭母竹、竹蔸、竹鞭。而无鞭母竹不能上山造林。

Analysis on Forestation Effect of Different Reproductivities of Phyllostachys heterocycla cv. Pubescens

Based on five years' survey of st ands which planted with stems, rhizomes, non-rhizomes mother bamboo and mother bamboo with rhizomes, the result shows that the plantation planted bamboo with r hizome grows better in survival rate.The cost of plantation is higher. The plant ation planted with stems grows next. Non-rhizomes mother bamboo can survive, bu t cannot grow new bamboo. To sum up the order of selection,reproductivity is mot her bamboo with rhizomes, stems, rhizomes.Non-rhizomes mother bamboo can't be u sed for forestation.
