摘要
研究了不同施氮水平对鲜食糯玉米产量和品质的影响,结果表明:适当增施氮肥可明显改善糯玉米的经济性状,并且提高产量和改善品质;但施氮超过420kg/hm2时,鲜食糯玉米的产量及品质明显下降。以产量和品质作为衡量指标,鲜食糯玉米以施用纯氮360kg/hm2为宜。
The waxy maize which was popularized in Guangdong province was used as the experimental material and the effects of nitrogen application with N 300,360,420,480 kg/hm^2 on yield and quality of waxy maize was studied. The results indicated that tile economic characteristic, yield and quality of waxy maize were getting better apparently with the increasing of N application rate in the range from N 300- 420 kg/hm^2, but they were decreased obviously when the N application was over 420 kg/hm^2.The results suggested that N applicale rate 360 kg/hm^2 for waxy maize was best for yield and quality.
