摘要
研究了毛竹(Phyllostachys heterocycla cv.Pubescens)林下栽培竹荪(Dictyophora echinovolvata)对春笋产量、竹材胸径及林地土壤的影响。结果表明,竹荪试验区比对照区春笋的株数提高35.7%,产量增加28%;试验区的新竹胸径比对照区胸径提高12.2%,试验区内新竹胸径比老竹提高6.77%;试验区土壤的容重比对照降低5.4%,土壤在有机质、水溶性氮、速效磷、速效钾含量上比对照都有明显的增加,特别是速效磷增加3.75倍。
Experiment was conducted on cultivation of Dictyophora echinovolvata in Phyllostachys heterocycla cv. pubescens stand. The result demonstrated that spring shoot number and yield in cultivated stand increased by 35.7% and 28% compared with that in the control（no cultivation）. DBH of new bamboo in cultivated stand increased by 12.2% and 6.77% compared with that of the new bamboo in the control and that of old ones in the cultivated stand. Soil organic matter, soluble nitrogen, available phosphorus and potassium content in cultivated stand was higher than that in the control, especially available phosphorus.
