鸭子品种间的差异对稻鸭共生系统中水稻的生长特性可能有重要影响。为了探究鸭子品种对水稻生长特性的影响,选取水鸭(SY)、洋鸭(YY)和绿头鸭(LTY) 3个常见鸭品种作为处理,以水稻常规单作(CK)为对照,采用随机区组设计的方法进行田间小区试验,研究其对水稻根部、茎部、叶部性状及水稻产量的影响。结果表明: YY和LTY处理虽然在水稻生育前期对水稻根、茎、叶部性状产生了一定负面作用(株高除外),使其性状表现相比CK显著性降低,但YY和LTY处理缓解了根、茎、叶的衰老和退化,使其性状在水稻生育后期显著优于CK,最终通过显著提高水稻有效穗数和结实率显著提高了水稻产量,但显著降低了每穗总粒数,每穗实粒...

The differences of duck varieties may affect the growth characteristics of rice in rice-duck symbiosis system. We selected Youxian partridge duck (SY), Muscovy duck (YY) and mallard (LTY) to explore the effects of different duck varieties on rice growth characteristics, with the conventional rice monoculture as the control (CK). A field plot experiment following randomized block design was used to study the changes of rice root traits, stem traits, leaf traits, and rice yield. The results showed that the YY and LTY treatments had certain negati...
