| 摘 要： | 进行了氮肥施用量及施用模式对龙粳26产量影响的试验,结果表明:施氮总量186.0 kg/hm2,基肥、第1次蘖肥、第2次蘖肥、调节肥、穗肥施用比例为4.5∶2∶0∶1.5∶2时产量最高,为9 185.70 kg/hm2;产量构成因素与产量的相关性分析发现,单位面积穗数、穗长与产量相关性最大,相关系数分别为0.993、0.904,实际生产中应该兼顾各产量因素,以达到高产。

| Abstract: | Effects of application amount and model of nitrogenous fertilizer on the yield of Longjing 26 were discussed.The results showed that:when total nitrogen was 186.0 kg/hm2,and basal fertilizer,first tillering fertilizer,second tillering fertilizer,adjusting fertilizer,ear fertilizer ratio was 4.5∶2∶0∶1.5∶2,the best yield was 9 185.70 kg/hm2.Correlation analysis of yield and yield components showed that panicles per unit and spike length had an significant correlation with yield.The correlation coefficient were 0.993 and 0.904,respectively.In actual production,each factor of yield components should be taken into account,in order to obtain the highest yield. |
