不同经营措施对毛竹林春笋生长的影响

Effects of different managements on the spring shoot yield in Moso bamboo forest (Phyllostachys pubescen)

开展3种经营措施(浅锄+穴施复合肥、浅锄、不抚育管理)对毛竹春笋生长的影响试验。结果表明:不同的经营措施对毛竹林的出笋期、春笋产量和成竹数均有极显著的影响,对平均退笋高度影响不显著。采用劈草、浅锄、施肥和喷灌等经营措施的毛竹林出笋最早、结束出笋最迟、出笋周期最长、出笋量也最多,同时成竹数和成竹率也最高。

The effects of three di fferent managements(Shallow hoe and compound fertilizer applied in holes, shallow hoe, no tending) on the growth of Moso bamboo shoots were tested. The results indicated that different managements had significant influences on the shooting period,yield and number of new growth of Moso bamboo forest, but had no significant effect on the average height of degenerated shoots. The bamboo forest adopting such management measures as grass cutting, shallow hoeing, fertilization and sprinkler irrigation has the earliest bamboo shoots,the latest shoot ending, the longest bamboo shoot cycle and the largest amount of bamboo shoots. Meanwhile, the quantity and percentage of new growth are the highest.
