摘要
研究了双层覆盖、单层覆盖对毛竹林出笋时间、笋期、竹笋产量、竹林土壤温湿度、幼竹及幼鞭生长状况等的影响。结果表明:覆盖措施显著提高竹林土壤温度,但对土壤含水率影响不显著;双层覆盖竹林出笋时间较单层覆盖和对照竹林分别提前6 d和15 d,笋期较单层覆盖和对照竹林分别增加9 d和15 d;双层覆盖竹林相对于对照竹林在竹笋净产量和竹笋可食部分重量方面分别增加95%和102%;双层覆盖竹林幼鞭平均深度明显低于对照竹林,跳鞭数量明显高于对照竹林,表明覆盖措施对竹鞭生长具有不利影响。
Effects of double-layer and single-layer covering on the time and period of bamboo shoot emergence,bamboo shoot production,soil temperature and moisture,growth status of young bamboo and rhizome in bamboo forest of Phyllostachys pubescens were studied in this paper.The results showed that,the covering measure significantly increased the soil temperature,but no significant effects on the soil water content.The time of bamboo shoot emergence in bamboo forest of double-layer covering was earlier than that of single-layer covering and control check measures for 6d and 15d respectively,and the period of bamboo shoot emergence of double-layer covering was increased by 9d and 15d respectively compared to that of single-layer covering and control check measures.The net production and the edible part weight of bamboo shoot in double-layer covering were respectively increased by 95% and 102% compared to that of control check measures.The average depth of young rhizome in double-layer covering was significantly lower than that of control check measures,while the number of jumping rhizome was obviously superior to that of control check measures,thus it indicated that the covering measures could cause negative effect on the growth of young rhizome.
