title: [Effects of rice-duck farming system on Oryza sativa growth and its yield].
abstract: The study showed that under rice-duck farming, the number of rice non-productive tiller reduced significantly, the ratio of its effective panicles increased by 8.08 %, and its basal penetration light rate enhanced by 4.05%. At full-heading and maturing stages, the green leaf ratio under rice-duck farming was 6.01% and 10.65% higher than the control, and the leaf chlorophyll content was increased by 2.90% and 17.82%, respectively. Under rice-duck farming, the root vigour at full-heading stage and the photosynthesis capability of flag leaf at grain-filling stage were increased by 24.2% and 15.73%, which could accumulate more assimilative matter, and increase the harvest index and yield by 2.87% and 4.93%, respectively.
