采用田间试验及环境经济学方法研究免耕"稻鳖鱼"共生模式的环境经济效益并提出相关对策。试验共设免耕稻鳖鱼（RTF）,免耕稻鳖（RT）、免耕稻鱼（RF）,免耕水稻单作（RM）4个处理。田间试验结果表明,RTF,RT,RF控草效果明显;孕穗期RTF病蔸率和病株率分别比RM低71.1%和56.3%。RTF固碳量比RM增加8.7%,甲烷（CH4）排放总量减少39.9%。环境经济学分析结果表明,RTF、RT、RF的财务效益,比RM分别增加了52 450、24 500、23 940元/hm2,RTF、RT、RF和RM环境经济效益分别为53 547、25 385、24 927和559元/hm2;研究结果表明,免耕稻鳖鱼共生模式生态和经济效益高,具有良好的发展和推广前景,可作为农业供给侧结...

This article has been studied the financial and environmental economic benefits of "no-tillage rice-turtle-fish" symbiotic model by field experiment and environmental economic method. The field experiment set up 4 kinds of treatment: no-tillage rice-turtle-fish(RTF), no-tillage rice-turtle(RT), no-tillage rice-fish(RF), no-tillage rice-monoculture(RM). The field experiment showed that RTF, RT and RF model can control the weeds significantly; the diseased hills ratios and the diseased plant ratios of booting stage in RTF were lower than RM 71.1% and 56.3%, respectively. The C sequestration of R...
