| 摘 要： | 本研究通过大田小区对比实验,探讨了鸭稻共作对水稻植株生长性状与产量性状的影响效果。研究结果表明,鸭稻共作在一定程度上降低了水稻植株的高度和水稻地上部的生物量,但增大了水稻地下部的生物量和根冠比,有利于水稻地下部根系的发育,并在一定程度上增强了水稻的抗倒伏能力;同时,鸭稻共作能提高水稻中后期叶片的叶绿素a和叶绿素b的含量以及叶绿素a/b值,可防止水稻在后期的过早枯黄与衰败,从而增强水稻叶片光合作用的性能及其持续时间;鸭稻共作还能够促进水稻的有效分蘖,增加水稻的有效穗数和成穗率,减少空(秕)粒数,提高水稻的实粒数和结实率,从而有利于水稻产量的形成。这些研究结果可为鸭稻共作生态技术的生产实践与示范推广提供理论依据。 |
| 关 键 词： | 鸭稻共作 生长性状 产量性状 叶绿素含量 根冠比 |
