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1036.5kg·hm-2,成鸭238.9~489.3kg·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.

Abstract: 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.
