摘要
试验表明．稻鱼鸭种养共生，水稻增产 １０％以上，同时增收鲜鱼 １０３６．５ ｋｇ· ｈｍ－２，成鸭２３８．９～４８９．３ ｋｇ·ｈｍ－２；水稻土壤全Ｎ、Ｐ、Ｋ和有机质含量分别增加２７．９、 ４４． ３、６． ５和 ２８． ２％，提高了土壤肥力；水稻植株虫口量最少．稻鱼鸭共生大大提高了稻田 的产出和效益．属良性循环的高效复合生态农业．
The study slowed that in a rice-fish-duck. co-growth ecosystem. the rice production was increased by above 10 %, with an additional increase of 1036. 5 kg' hm-2 fish and 238. 9~ 489. 3 kg' hm-2 adult duck. The total N, P, K and Organic matter contents of paddy soil were increased by 27. 9, 44. 3, 6. 5 and 28. 2%, respectively, and the insect pest of rice was also decreased. This ecosystem largely increased the output and economic benefit, being a well recycled and highly effective agro-ecosystem.
