【摘要】 在覆膜滴灌条件下,研究了氮磷钾肥的配施对加工番茄的产量影响,结果表明:T3(N300kg.hm-2P2O5210kg.hm-2K2O150 kg.hm-2)、T5(N300kg.hm-2P2O5105kg.hm-2K2O75 kg.hm-2)、的肥料配比及施用量适合于加工番茄的高产,产量分别达到111360 kg.hm-2、111450 kg.hm-2,但从经济效益分析T5的经济效益最好,每公顷比对照CK(N0kg.hm-2P2O50kg.hm-2K2O0 kg.hm-2)净增收2487元。更多还原

【Abstract】 In this paper,the influence of NPK matchs on the growth and yield of processing tomato were studied.The result indicated thmt(1)Treatment 1(N 0kg hm-1;P2O5 0kg hm-1;K2O 0kg hm-1) of yield was 92760kg hm-1 and biological chmracteristics were worse thmn another treatments,so NPK fertilizer is effective.(2)Application fertilizer of Treatments 4(N 30kg acre-1;P2O5 21kg acre-1;K2O 15kg acre-1)is most,but its yield is lower,so we think application fertilizer of Treatments 4 is over normal level.(3)Peasant may increase income 2480yuan hm-1 by Treatment 5.更多还原
