Abstract
【Objective】It aimed to study the efffect of N,P and K coupling atcion on growth and yield of processing tomato under film drip irrigation.【Method】A field trial was carried out to study growth and yield of processing tomato by using 3414 complete test scheme of N,P and K fertilizer.【Result】The result showed that the sequare equation of three functions of N,P and K was insignificant;the effect of different proportion N,P and K application on yield of processing tomato was significant,the yield was decreased when using unsufficient fertilizer and the growth was thrived when over-fertilization,the effect of N on processing tomato growth was more significant than that of P and K;the yield of N2P2K2,N2P3K2 and N2P2K1 other treatments was more than 9 000 kg/hm2,which was significant high than the other treatments.【Conclusion】 The best proportion of N∶P∶K was 9∶3∶2,which could gain the highest yield and benefit
