摘要
以超级稻甬优6号为试验材料,研究其作晚稻栽培的氮磷钾肥料效应,结果表明:氮肥的增产效应居首位,其次是钾肥。晚稻最高产量每667 m2施肥量为N 10.4 kg、P2O51.4 kg、K2O9.0 kg,最高产量为482.4 kg;最佳经济效益施肥量为N 7.2 kg、P2O50.9 kg、K2O 9.0 kg,每667 m2经济效益达1 061.5元。
This paper studied the fertilizer efficiencies of N, P and K on super rice Yongyou No. 6 when used it as late rice cuhivar. The results showed that, N fertilizer showed the best yield-increasing effect, then K fertilizer. The N, PzOs and K2O fertilization amounts for the maximum grain yield were 10.4 kg/667 m2 （156 kg/hm2）, 1.4 kg/667 m2 （21 kg/hm2）, 9.0 kg/667 m2 （ 135 kg/hm2 ） respectively and could reach 482.4 kg/667 m2 （7 236 kg/hmz ） rice grain yield, and the fer- tilizer amounts for the maximum economic benefit were N 7.2 kg/667 m2 （ 108 kg/hm2 ）, P205 0.9 kg/667 m2 （ 13.5 kg/ hm2 ） and K20 9.0 kg/667 mz （ 135 kg/hm2 ） respectively and could get economical benefit by 1 061.5 RMB Yuan/667 mE （ 15 922.5 RMB Yuan/hm2 ）.
