在福建省三明市三元区岩前镇、将乐县漠源乡开展了毛竹笋材两用林3414田间施肥试验，结果表明，土壤肥力对毛竹笋竹产量的贡献率分别是39．54％（岩前点）、59．51％（漠源点）。不同试验点的氮磷钾肥料对竹林产量的增产效果有差异，岩前点肥料效应高于漠源点；平均增产效果以氮肥最为显著，其次是磷肥、钾肥。各肥料的利用率以钾肥的利用率最高，氮肥居中，磷肥最低。在中低产量水平的笋材两用竹林中，施氮磷钾配比肥对竹林产量有明显的增产效果，可发挥良好的肥料效应。

The 3414 field fertilizer tests of shoot and timber producing stands of Phyllostachys edulis were held in Yangqian Town and Moyuan Township , Sanming City.The results showed that soil fertility contributed 39.54%( Yangqian test point ) and 59.51%(Moyuan test point ) respectively to the shoot and timber yield .The differences were found on yield-increas-ing effect for shoot and timber production between two test points after the application of N , P, K fertilizer, fertilizer benefit in Yangqian test point contributed more to bamboo yield than that in Moyuan test point .N fertilizer had the best yield-in-creasing effect , while P fertilizer and K fertilizer were lower than the former .K fertilizer had the best fertilizer utilization rate , N fertilizer takes second place and P fertilizer was the lowest .In medium and low yield levels of bamboo stands , there were significant increases on yield for shoot and timber producing stands after the application of nitrogen , phosphorus, potas-sium fertilizer with rational proportion , and the complete fertilizer had the adequate fertilization benefit .
