摘要
氮肥是水稻产量的限制因子,试验研究了在稻田中等肥力条件下施用不同氮肥量,对松辽186品种产量的影响。试验结果表明,在5个施纯氮肥量处理因子中,处理1(施纯氮肥量12.9 kg/667 m^2)产量最高,为621.7 kg/667 m^2。这仅是1 a的试验结果,是否为最佳施氮量,尚需对松辽186品种的耐肥性作进一步研究,以期得出更加科学合理的有参考价值的数据。
Nitrogen fertilizer was the limiting factor for the yield of rice. The test researched the effect of different nitrogen application on the yield of he new rice variety named Songliao-186, the result indicated that treatment 1（the pure nitrogen fertilizer was 12.9 kg/667 m^2） had the highest yield which was 12.9 kg/667 m^2 among the five treatments,but it was only the conclusions of one year, whether it was the best optimal amount should be further researched to reach the more scientific and rational valuable data.
