| 摘 要： | 在常规栽培和优化栽培模式下,分别设置施氮量折合成纯氮0,105,142.5,180 kg/hm2的4个缓释氮肥用量处理,研究了缓释氮肥用量对超级杂交早稻株两优02产量和生理特性的影响.结果表明:在优化栽培模式下,各施氮量处理的产量均高于相应的常规栽培处理,其中纯氮用量142.5 kg/hm2的处理产量最高,而常规栽培各处理的产量则随施氮量的增加而提高；在优化栽培和常规栽培模式下,各时期叶片中的过氧化氢酶(CAT)活性、可溶性糖含量和根系活力均以施氮量180 kg/hm2的处理较高；施用纯氮142.5 kg/hm2的处理乳熟期-成熟期叶片中能保持较高的超氧化物歧化酶(SOD)活性和较低的丙二醛(MDA)含量,有利于延缓水稻功能叶片的衰老.

| Abstract: | The effects of application amount of slow-re le ase nitrogen fertilizer were studied on the physiological characteristics and gr ain yield of Zhuliangyou 02,a widely-used early-cropping super hybrid rice va riety.The research was conducted with two cultivation modes,i.e.,the optimize d and conventional modes,and four nitrogen application levels of the slow-rele ase nitrogen fertilizer at the pure N rates of 0(N0),105(N1),142.5(N2) and 180 kg/hm2(N3),respectively.The results showed that the grain yields of a... |
