减量施肥后不同水肥一体化模式对春大棚辣椒产量和效益的影响

以常规施肥为对照,连续两年在化肥总养分减少30%的条件下比较2种水肥一体化模式对浙江杭嘉湖地区春大棚辣椒产量和效益的影响。结果表明:与常规的穴施追肥相比,减量施肥的2种水肥一体化模式均促进了春大棚辣椒的生长,有效提高产量、效益和品质,其中半程水肥一体化模式明显优于全程水肥一体化模式。

Effect of Different Water and Fertilizer Integration Models on Yield and Benefit of Spring Greenhouse Pepper Based on Reductive Fertilization

Taking conventional fertilization as the contrast，through 2 successive years experiments under 30% total chemical fertilizer reduction，this paper compared the effects of 2 water and fertilizer integration models on yield and benefit of spring greenhouse pepper．The results showed that compared with the conventional acupoint application，both of these 2 water and fertilizer integration models had promoted the growth of spring greenhouse pepper and effectively improved its yield，efficiency and quality．In terms of comprehensive performance，the half-way water and fertilizer integration model was obviously better than fullscale water and fertilizer integration model．
