摘要
进行芥菜不同施氮量的田间试验,结果表明:随着施氮量的增加,芥菜产量呈先增加后降低的趋势;每667 m2施氮量为20.96 kg时芥菜产量最高,为4452.7 kg;每667 m2施氮量为19.71 kg时,芥菜经济效益最高,为3318.78元。
A field experiment of different N application rate to mustard was carried out. The results showed that,under the condition in this experiment,with the increase of N application amount,the mustard yield appeared a trend of increasing first and then lowing down. When the nitrogen rate per 667 m2 was 20. 96 kg（ 314. 40 kg / hm2）,the yield was the highest of4452. 7 kg（ 66 790. 50 kg / hm2）,and when the nitrogen rate was 19. 71 kg（ 295. 65 kg/hm2）,the economic benefit was the highest of 3318. 78 yuan（ 49 781. 7 yuan / hm2）.
