摘　　要：通过对毛竹林地采用不同覆盖处理(稻草覆盖、稻草谷壳覆盖、竹叶覆盖),研究其对笋高及地径的影响,为毛竹高质高产提供科学依据。春季对样地竹笋进行连续观测,结果表明:地表覆盖能明显促进笋高、地径的生长,但是,不同的覆盖物产生的作用大小不同。3种覆盖物中稻草覆盖产生的作用最大,稻草谷壳覆盖次之,竹叶覆盖最小。分析结果表明,采用地表覆盖的管理措施对毛竹的生长有重要意义。因此,可以采用稻草覆盖作为改善毛竹低产的有效措施。Through treating the bamboo forests with different mulching modes （straw mulching, straw and chaff mulching, bamboo leaves mulching） on the bamboo forestlands, the effects of the different treatment modes on the bamboo shoots height and diameter were investigated in order to provide a scientific theory basis for breeding high quality and yield bamboo. In spring, the observations and records on the bamboo shoots were conducted for seven consecutive days. The results show that these mulching modes obviously promoted the growth of bamboo shoots and ground diameter, but the effects of these mulching modes were different;among the modes, the straw mulching played the most obvious role, the straw and chaff mulching took the second place, the bamboo leaves mulching’ role was minimal; the action of the soil surface mulching on the growth of bamboo is significant. Therefore, it is suggested that the straw mulching mode should be used as an effective measure to improve the low yield of bamboo forests.
