不同抚育措施对毛竹出笋成竹及生长量的影响 　　摘要 试验采用不同抚育技术措施（处理A：全面劈草清杂+垦复+施肥；处理B：全面劈草清杂+垦复；处理C：全面劈草清杂；CK：不抚育）进行毛竹林出笋量及生长量比较，结果表明：不同抚育技术措施对毛竹出笋成竹量及新竹生长的影响极为显著，试验以处理A的平均出笋数、平均成竹数、平均成竹率、平均胸径、平均高最高，分别达973个/hm2、926株/hm2、95.2%、11.8 cm、13.2 m；其中：平均出笋数比处理B、C、CK分别提高20.9%、59.0%、140.2%，平均成竹数比处理B、C、CK分别提高24.6%、69.9%、160.8%，平均成竹率比处理B、C、CK分别提高2.9、6.0、7.6个百分点；平均胸径比处理B、C、CK分别提高21.6%、40.5%、66.2%，平均高比处理B、C、CK分别提高13.8%、23.4%、40.4%；试验处理的各项指标高低顺序依次为处理A处理B处理CCK（对照） 关键词 毛竹林；抚育措施；出笋量；生长量 中图分类号 S795.7 文献标识码 A 文章编号 1007-5739（2016）14-0146-01 Effects of Different Tending Measures on Shoot Number and the Growth of Phyllostachys edulis. LU Li-xia （Forestry Bureau of Fuding City in Fujian Province，Fuding Fujian 355200） Abstract Experiment with different tending technical measures（treatment A：comprehensive chopping grass and clearing+improvement of stand condition+fertilization；treatment B：comprehensive chopping grass and clearing+improvement of stand condition；treatment C：comprehensive chopping grass and clearing；CK：no tending）was done to analyze the shoots and the growth of Phyllostachys edulis.The results showed that the effects of different tending technical measures on the shoots numbers and the growth were very significant.The number of shoots，the numbers of bamboo shoots，the rate of bamboo shoots，DBH and plant height of treatment A were the hightest，respectively up to 973/hm2，926 plants/hm2，95.2%，11.8 cm，13.2 m.Among them，the number of shoots increased by 20.9%，59.0% and 140.2% than treatment B，C，CK respectively.the average into Phyllostachys edulis.ratio treatment B，C，CK （control） increased by 24.6%，69.9% and 160.8% than treatment B，C，CK，respectively.the rate of bamboo shoots increased by 2.9、6.0、7.6 percentage points，respectively；the DBH increased by 21.6%，40.5% and 66.2% than treatment B，C，CK，respectively.The plant height increased by 13.8%，23.4% and 40.4% than treatment B，C，CK，respectively.The influence order of each index was as follows：treatment A treatment B treatment CCK（contrast）.
