摘    要:在田间小区试验条件下 ,以迟熟中粳稻 951 6和杂交中籼稻汕优 63为试验材料 ,研究不同施氮量和栽插密度(行距 )对水稻产量和稻米品质的影响。结果表明 :中粳稻 951 6适宜施氮量为 2 2 5kg/hm2 ,栽插行距为 2 6.6cm;汕优63适宜施氮量为 1 50 kg/hm2 ,适宜栽插行距为 3 3 .3 cm。在此试验条件下 ,可获得适宜穗数 ,提高结实率和粒重 ,降低垩白米率和垩白指数 ,提高蛋白质含量 ,改善稻米的加工品质

关 键 词:水稻  施氮量  栽插行距  产量  稻米品质

Abstract:The effects of amount of nitrogen accumulated and density on yield and grain quality of rice were systematically studied with mid\|maturing rice Japonica 9516 and Indica Shanyou 63 in experimental farm of Yangzhou University. The results were as follows: proper amounts of N\|applied and row space with 9516 were 225 kg/hm 2 and 26.6 cm respectively, those of Shanyou 63 were 150 kg/hm 2 and 33.3 cm. These are proper conditions to increase ripe grain percentage and grain weight after heading stage, and can decrease the chalkiness and increase the protein content of grain, and can improve merching quality.
Keywords:rice  N\|applied amount  row space  yield  rice quality
