| 摘 要： | 对2007～2010年水稻不同氮肥施用量试验结果进行汇总,结果表明:在一定的氮肥施用量范围内随着施氮量的增加水稻产量、单株分蘖率、穗粒数、稻米垩白率、蛋白质含量均呈增加趋势;千粒重、食味值随着氮肥施用量的增加呈下降趋势.不同年际氮肥的最佳施用量受气象条件影响明显.

| Abstract: | Nitrogen fertilisers of different amount from 2007 to 2010 were collected,the results showed that the yield,tillers rate,grains per panicle,chalkiness rate and protein content showed an increasing trend along with the rise of nitrogen fertilisers,1000-grain weight and palatability value were the reverse.The optimum amount of nitrogen fertilisers was significantly affected by meteorological factor. |
