摘　　要：以赤谷9号为试验材料,研究不同的施氮量(0、150、300、450、600 kg/hm2)对谷子产量的影响。结果表明:氮肥施用量为450kg/hm2时,谷子产量达到最高为5 210.95 kg/hm2,比不施氮肥增产713.15 kg/hm2,增加经济效益729.19元/hm2。Take Chigu 9 as test material,effects of different amount of nitrogen （0,150,300,450,600 kg/hm2） on millet were tested.The resuhs showed that the nitrogen application amount was 450 kg/hm2,the yield of Chigu 9 reached 5 210.95 kg/hm2,which increased by 713.15 kg/hm2,and the economic benefit increased by 729.19 yuan/hm2, compared with no nitrogen condition.
