摘　　要：采用厩肥、谷糠、稻草进行覆盖后,显著增加了出笋时间和出笋产量,其中以厩肥效果为最佳,笋期延长29 d;不同覆盖物对于黄甜竹的竹高存在显著影响,覆盖厚度对于竹高生长没有显著影响;覆盖物及覆盖厚度对黄甜竹的胸径生长没有显著影响。不同的覆盖材料对黄甜竹地上各部分生物量影响表现为:厩肥>谷糠>稻草,而且秆部生物量均大于枝叶部生物量,生物量在地上各部分的分布是不均匀的。3 kinds of mulches were adopted to improve the period and yield of bamboo shoots. The optimal mulch barnyard manure, which prolonged 29 d period of bamboo shoots. There was significant difference between different mulches and bamboo height, but no difference between mulch thickness and bamboo height. There is no evident impact for different mulches and mulch thickness on mean D. B. H. The impacts of different mulches on bamboo biomass on the ground were barnyard manure 〉 rice bran 〉 straw, and the distribution of biomass in individual tree is asymmetric, which was that the biomass of stem is greater than that of branches and leaves.
