摘　　要：于2021—2022年,以福建省建瓯市房道镇的毛竹林为研究对象,开展不同肥料施肥试验,研究不同竹龄(Ⅰ、Ⅱ、Ⅲ、Ⅳ度)、不同高度部位(胸径处、离地3.5 m处、末梢处)的毛竹竹秆含水率、秆径、壁厚差异,以及施用不同肥料(商品有机肥、无机复合肥)对毛竹竹秆胸径、胸径处壁厚以及竹秆生物量的影响。结果表明:随着竹秆高度和竹龄的增加,毛竹竹秆含水率降低,且随着秆高的增加,秆径和壁厚显著降低(P<0.05);而不同竹龄毛竹中,仅Ⅰ度毛竹的秆径和壁厚显著高于其它竹龄毛竹(P<0.05)。施肥有利于新竹生长,施肥效果表现为无机肥>有机肥>不施肥,但有机肥与无机肥对新竹生长的影响差异不显著(P<0.05)。From 2021 to 2022,taking the moso bamboo(Phyllostachys edulis)stands at Fangdao Town,Jian′ou City as the materials to carry out fertilization tests with different fertilizers.The moisture content,culm diameter and wall thickness differences of bamboo culm in different bamboo ages(Ⅰ、Ⅱ、Ⅲ、Ⅳdegrees)and heights(at DBH,at 3.5 m above the ground,at the end),as well as the effects of different fertilizer types such as commercial organic fertilizer,inorganic compound fertilizer on the DBH,wall thickness at DBH and culm biomass were studied.The results showed that with the increase of culm height and age,the moisture content of culm decreased significantly,and with the increase of culm height,the culm diameter and wall thickness decreased significantly(P<0.05),while the culm diameter and wall thickness of I degree bamboo age were significantly higher than those of other bamboo ages(P<0.05).Compared with no fertilization,fertilization was beneficial to the growth of newly grown bamboo,the effect of fertilization was inorganic fertilizer>organic fertilizer>no fertilize,while the effects of organic fertilizer and inorganic fertilizer on newly grown bamboo growth were not significant(P<0.05).
