    摘要:

    为了明确松玉419在吉林省中部半湿润区的适宜施氮量,在大田条件下设置了每公顷纯氮用量0 kg,100 kg,160kg,220 kg和280 kg共5个氮肥量级,研究不同氮肥量级条件下,松玉419的生理指标、产量、产量性状及品质指标。结果表明,随着氮肥用量的增加,叶绿素相对含量提高,叶面积指数增大增强,蛋白质和脂肪含量增加,淀粉含量下降。产量表现为先升后降趋势,产量达到最高而品质较为协调的施氮量为220~240 kg/hm2

    Abstract:

    To find out the rational nitrogen application rates for new high-yield maize variety Songyu 419 in semi-humid areas of Jilin province, field experiment was carried out. Five nitrogen application rates were designed, whichwere 0, 100, 160, 220 and 280 kilograms per hectare. Under the different nitrogen application rates, the physiologi-cal characteristics, yield, yield traits and quality characteristics of Songyu 419 were studied. The results showed thatwith the increase of nitrogen fertilizer, the relative chlorophyll content and leaf area index increased, the protein andoil content increased and starch content decreased, the yield increased at first and then decreased. It suggested thatthe optimal nitrogen application rate was 220-240 kg/ha for the coordination of yield and quality.
