摘要: 以南粳9108为试验材料,研究了施氮量对盐碱地水稻产量及品质的影响。结果表明,在一定范围内,水稻产量随着施氮量的增加而增加,在施氮量为20 kg/667 m2时产量最高;盐碱地条件下,增施氮肥会增加稻米的垩白粒率、垩白度和蛋白质含量,降低直链淀粉含量;此外,施氮量的增加还会显著降低稻米的蒸煮品质与食味品质。

Abstract: A field experiment was conduct with Nanjing 9108 as material. The effect of nitrogen fertilizer application on rice yield and quality on saline-alkaline land were studied. The results showed that the yield improved with nitrogen fertilizer application increased within a given range, and it obtained the maximum yield under nitrogen fertilizer application of 20 kg/667 m2; the chalky rice rate, chalkiness degree and protein content of rice were increased with the increasing amount of nitrogen fertilizer, while amylose content of rice was decreased. In addition, the eating characteristic properties of rice also decreased.
