【摘要】 为提高毛竹笋用林竹笋、竹材产量 ,对不同立地条件的毛竹笋竹两用林进行不同施肥量试验 ,结果表明 :不同量的施肥均能提高竹笋、竹林产量 ,但过量施肥 ,不但不能高产 ,还会略有下降 ;而连年施肥 ,春笋产量均呈显著差异 ,第 3年的春笋产量提高最快 .不同立地条件中山凹的 750 0kg/hm2 目标产量投入产出比最高 ,为1∶1 7 1 7,经济效益极佳更多还原

【Abstract】 To increase shoot and timber yield of Phyllostachys heterocycla var. pubescens stand,experiment of fertilizer application with different quantity was carried out in bamboo stands for both shoot snd timber uses with different site index.The result showed that shoot and timber yield increased,but overapplication would decrease the yield.Current annual application made significant difference of spring shoot yield,especially in the third year with the highest increment.In stands of different site index,the target input-output ratio of 7 500kg/hm 2 in corrie was 1∶17.17 the highest,with high economic benefit.更多还原
