摘　　要：在福建省上杭白砂国有林场,对大头典竹笋用林开展林地不同覆盖物(有机肥、谷糠、稻草、木屑)及不同覆盖厚度(5、10、15、20 cm,)试验。结果表明:4种覆盖物及覆盖厚度对大头典竹出笋量具有不同程度的影响,并且笋产量在不同覆盖物、覆盖厚度间差异均达极显著水平;覆盖物以有机肥最好,木屑、谷糠次之,稻草最差,覆盖物厚度以10 cm最佳,其次为15、20 cm,5 cm厚的产量最低。说明覆盖物、覆盖厚度对提高笋产量有重要的影响,可增收10875~51000元·hm^(-2)。A contrast test on four mulches （ organic fertilizer, rice bran, straw, and sawdust） in D. beecheyana var. pubescens forest and the coverage thickness （5,10,15 and 20 cm） of different mulches was conducted. The result showed that four kinds of mulches and coverage thickness had different effects on the yield of bamboo shoots, and their influence on the production of bamboo shoots differed significantly. Among the four mulches, organic fertilizer was the best, followed by sawdust, and rice bran, and straw was the worst;in terms of coverage thickness, 10 cm was the best, followed by 15 cm and 20 cm, and 5 cm was the worst, which indicated the significant influence of mulches and coverage thickness on the yield of bamboo shoots,with an income increase of 10875 -51000 yuan per hectare.
