摘要
通过在毛竹笋、竹两用林中挖掘鞭笋对冬笋、春笋、竹材产量和竹鞭生长情况影响的分析,结果显示:①鞭笋7月开始挖掘,每600m2冬笋产量增加113.66kg,春笋减少7.46kg,竹材增加74.12kg。②处理间各种产量无显著影响F<F0.05(4.46),受气象因子干扰,重复间冬笋产量有显著差异F=4.02>F0.05(3.84),春笋F=7.77>F0.01(7.01),竹材F=38.68>F0.01(7.01),有极显著影响。③2m2样方中的竹鞭段总长度增加545.0cm,竹鞭段支数增加4支,竹鞭大小无变化。④竹鞭在土壤中垂直分布15cm内鞭段总长度增加18%,鞭段支数增加10%。
The paper analyzed the effect of rhizome digging in moso culm-shoot forests on the production of winter and spring shoots,culm yielding and rhizome growth.The results showed that：1）rhizome began to be dug in July,winter shoot output increased by 113.66 kg/600m2,spring shoots reduced by 1.46 kg/600m2,and culm yielding increased by 74.12 kg/600m2.2）there was no significant effect among productions of winter shoot,spring shoot and culm FF 0.05 （4.46）,and due to meteorological factor,winter shoot output has a significant difference F=4.02F 0.05 （3.84）,spring shoot F=7.77F 0.01 （7.01）,culm F=38.68F 0.01 ,so there were clear differences.3）the total length of rhizome section in 2 m2 sample site was 54.50 cm,and the culm of bamboo rhizome increased 4,while the size of bamboo rhizome had no change.4）the total length of rhizome vertically distributed in 15 cm in the soil could increase by 18%,and rhizome number could increase by 10%.Rhizome should be buried in time and well.
