This paper investigated the effects of rice-duck integrated farming cultivation pattern on growth traits and yield traits of Nangeng 46. The results showed that rice-duck integrated farming reduced the plant height and effective panicle number of Nangeng 46, but increased grains number per panicle and seed-setting rate. Compared with conventional cultivation, the rice-duck integrated farming is lower in yield but more economic benefit, the economic benefit per 667 m2 was 525.05 yuan higher than that of conventional cultivation. At the same time, the rice-duck integrated farming reduced the application amount of chemical fertilizers and pesticides, protects the agricultural ecological environment, improves the safety of rice production, and provided a way for the sustainable development of agriculture.
Key words: Nangeng 46; rice-duck integrated farming pattern; yield; economic benefit
