摘　　要：通过田间肥料试验,研究撑绿竹专用有机无机肥料不同施肥量对新竹的生长、产量和经济效益的影响。结果表明:撑绿竹产量与施肥量之间的效应方程为y=–0.0039 x2+3.132 7 x+234.43,在施肥量0～679.53kg/667 m2范围内,当其达到401.63 kg/667 m2时,产量达最高(863.52 kg/667 m2)。不同施肥处理中,处理4的增产增收效果较好。综合考虑撑绿竹的产量和经济效益,推荐其合理的施肥量为339.77～401.63 kg/667 m2。The effects of different application amounts of the special organic-inorganic compound fertilizer on growth,yield and economic benefit of Bambusa pervariabilis×Dendrocalamopsis daii were investigated by field experiment in the present work.The results showed that the fertilizer response function between productions and fertilization levels of the bamboo was established as y=-0.0039 x2＋3.1327 x ＋ 234.43.The yield reached the highest（863.52 kg/667m2） when the fertilizer application amount were 401.63 kg/667m2 in the application range of 0 ~ 679.53 kg/667m2.The effects of increasing yield and income of the treatment 4 was better than others among different fertilization treatments.Considering the yield and economic benefit comprehensively,the suitable fertilizer application amounts was from 339.77 to 401.63 kg/667m2.
