双季早稻氮肥基蘖肥与穗肥不同比例简比试验

摘要

Different nitrogen application proportions of basal-tillering and panicle fertilizers in double cropping early rice were studied using the cultivar Jinyou 2155. The results showed that the treatment with the highest grain yield was the basal-tillering and spike proportion of 5∶5 for nitrogen fertilizer, which exhibited apparent yield increase.%以金优2155为材料，设置双季早稻氮肥基蘖肥与穗肥不同比例简比试验。结果表明，氮肥基蘖肥与穗肥比例为5∶5的处理产量最高，具有明显的增产效果。
