稻鱼鸭种养共生模式效益的研究及综合评价

Benefit analysis and comprehensive evaluation of rice-fish-duck symbiotic mode1

  • 摘要: 3年稻鱼鸭种养共生模式效益的研究表明,稻鱼鸭种养共生模式水稻增产lO%以上,增收鲜鱼1036.5kg/hm2,成鸭238.9~489.3kg/hm2;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。稻鱼鸭种养共生模式提高了稻田产量和效益,其生态环境质量指教为0.8155,属良性循环的高教复合生态农业模式。

     

    Abstract: Three years’study demonstrated that rice-fish-duck symbiotic model can improve rice production by over 10%,meanwhile produce more than 1036.5kg/hm2 of fish and 238.9~489.3kg/hm2 of adult duck.Total N,P,K and soil organic matter contents of paddy field are increased by 27.9%,44.3%,6.5% and 28.2% respectively.The number of insect pests is decreased .The symbiotic system largely increased the output and economic benefit.An ecological index (EI)of 0.8155 suggested that it was a high efficient and comprehensive eco-agriculture mode1.
