摘要： 为探明厢作稻鱼鸡共生模式对水稻群体生长及其产量的影响，设置厢作稻田养鸡（RC）、厢作稻田养鱼（RF）、厢作稻田养鸡养鱼（RFC）和厢作常规水稻栽培（CK）4个处理，进行连续2年（2020—2021年）的大田试验。结果表明：与CK处理相比，RC和RFC处理水稻灌浆期的叶面积指数分别提高了46.99%和46.32%（P<0.05），水稻成熟期穗干重分别提高了40.85%和33.39%（P<0.05）；RC和RFC处理孕穗-齐穗期的水稻地上部干物质积累量较CK处理分别提高了29.83%和33.71%（P<0.05）；RFC和RC处理齐穗-灌浆期的群体生长速率较CK分别提高了80.94%和75.34%（P<0.05），光合势较CK分别提高了34.25%和39.74%；RC和RFC处理孕穗期至齐穗期的光合速率较CK分别提高了3.05%～14.87%和6.45%～19.38%；RC、RFC和RF处理的水稻产量较CK分别提高了10.89%、13.23%和11.56%，RC处理的有效穗数较CK提高了13.25%（P<0.05）。综上，RC和RFC处理能提高水稻的叶面积指数、光合速率和群体生长速率，增加穗干重，从而达到稳产和增产效果。

Abstract: To clarify the effects of wide-ridge rice-fish-chicken co-culture on the growth and yield of rice, we carried out a field experiment for two consecutive years (2020-2021) with four treatments, including wide-ridge rice-chicken co-culture (RC), wide-ridge rice-fish co-culture (RF), wide-ridge rice-fish-chicken co-culture (RFC) and conventional rice cultivation (CK). The results showed that compared with CK, leaf area index of RC and RFC treatments increased by 46.99% and 46.32% (P<0.05) at grain filling stage, and panicle dry weight increased by 40.85% and 33.39% at maturity stage, respectively. The dry matter accumulation of rice aboveground at the booting to full heading stage under the treatments of RC and RFC increased by 29.83% and 33.71% (P<0.05), respectively. Population growth rates of RFC and RC treatments increased by 80.94% and 75.34% (P<0.05), and photosynthetic potential at the full heading to grain filling stage increased by 34.25% and 39.74% (P<0.05), respectively. The photosynthetic rate of RC and RFC treatments from booting stage to full heading stage increased by 3.05%-14.87% and 6.45%-19.38%, respectively. The rice yield under the treatments of RC, RFC and RF increased by 10.89%, 13.23%, and 11.56% respectively, while the effective panicle number of RC treatment increased by 13.25% (P<0.05). In summary, RC and RFC treatments could improve leaf area index, photosynthetic rate and population growth rate of rice, and increase panicle dry weight of rice, so as to achieve stable yield and yield enhancement.
