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。
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; K2O15kg 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.
