Effect of Nitrogen Fertilizer Application Rate on Yield Structure and Yield of Songliao-778

研究不同施氮量对松辽778产量结构及产量的影响,试验结果表明:处理2施纯氮量11.3 kg/667 m^(2),有效穗最多24.0万/667 m^(2),实粒数最多124.7粒/穗,结实率最高达90.2%,千粒重最大22.6 g,成穗率最高91.3%,产量最高为623.7 kg/667 m^(2)。

The effects of different nitrogen application rates on yield structure and yield of Songliao-778 were studied.The experimental results showed that:Treatment 2 pure nitrogen amount of 11.3kg/667 m^(2),effective ear up to 240,000/667 m^(2),the number of grains up to 124.7 grains/ear,the highest rate of seed setting up to 90.2%,1000-grain weight maximum 22.6 g,the highest rate of ears 91.3%,the highest yield of 623.7 kg/667 m^(2).
