| 摘 要： | 通过田间小区试验,研究了氮肥用量对水稻根系氧化力和产量以及稻米品质的影响。结果表明,在较当地常规施氮量减少42.8%和37.4%的条件下,水稻根系氧化力提高了4.4%或变化不明显;千粒重分别增加了0.59g和1.21g;空秕率分别降低了9.53%和7.43%;产量分别提高了4.2%和4.7%。稻米蛋白质含量和直链淀粉含量无显著变化。

| Abstract: | A field experiment was conducted to study the effects of lower amount of nitrogenous fertilizer on root oxidizing ability and yield,as well as grain quality of rice.In the experiment,the dosages of nitrogen were reduced by42.8%and37.4%compared with local conventional N application rate.The results show that treated with lower N rates,the oxidizing ability of rice root increased by4.4%and decreased by1.2%,1000-grain weight increased by0.59g and1.21g,blighted grain rates were lowered by9.53and7.43percentage points,yield increased by4.2%and4.7%.The changes in protein and amylase contents were not significant. |
