文章摘要:為了篩選具有可持續(xù)性、適合鄱陽(yáng)湖生態(tài)經(jīng)濟(jì)區(qū)的冬季綠色高效循環(huán)復(fù)合種植模式,通過2012年—2013年連續(xù)2年的田間定位試驗(yàn),采用AHP法和綜合指數(shù)法對(duì)鄱陽(yáng)湖生態(tài)經(jīng)濟(jì)區(qū)5種稻田復(fù)種輪作模式(冬閑?稻?稻?冬閑?早稻?晚稻,綠肥?早稻?晚稻?油菜?玉米||大豆?晚稻,油菜?玉米||大豆?晚稻,蠶豆?早稻?甘薯||玉米?蔬菜?甘蔗||大豆,蔬菜?甘蔗||大豆?綠肥?早稻?晚稻)的生態(tài)經(jīng)濟(jì)效益進(jìn)行了綜合評(píng)價(jià)。結(jié)果表明:按照晚稻價(jià)格比折算后,兩年間各種植模式中蔬菜?甘蔗||大豆種植模式的作物產(chǎn)量最高,其次是綠肥?早稻?晚稻,蠶豆?早稻?甘薯||玉米的作物產(chǎn)量最低。生態(tài)經(jīng)濟(jì)效益綜合評(píng)價(jià)表明,2012年各系統(tǒng)的綜合效益指數(shù)大小排序依次為:蔬菜?甘蔗||大豆〉油菜?玉米||大豆?晚稻〉蠶豆?早稻?甘薯||玉米〉綠肥?早稻?晚稻〉冬閑?早稻?晚稻,說明蔬菜?甘蔗||大豆種植模式"改稻為經(jīng)",是能夠帶動(dòng)稻田高產(chǎn)高效的種植模式,有利于農(nóng)業(yè)生產(chǎn)的可持續(xù)發(fā)展。2013年經(jīng)過稻田復(fù)種輪作后,各系統(tǒng)的綜合效益指數(shù)表現(xiàn)為:綠肥?早稻?晚稻〉蔬菜?甘蔗||大豆〉油菜?玉米||大豆?晚稻〉蠶豆?早稻?甘薯||玉米〉冬閑?早稻?晚稻,表明稻田冬種紫云英模式的綠肥?早稻?晚稻種植模式能兼顧三大效益,有利于農(nóng)業(yè)生產(chǎn)的可持續(xù)發(fā)展。從兩年的綜合效益結(jié)果來看,蔬菜?甘蔗|大豆→綠肥?早稻?晚稻模式能夠帶動(dòng)稻田高產(chǎn)高效,能兼顧經(jīng)濟(jì)效益、生態(tài)效益和社會(huì)效益,可解決糧食安全和農(nóng)業(yè)結(jié)構(gòu)調(diào)整及農(nóng)民增收等社會(huì)問題,而且對(duì)于冬季農(nóng)業(yè)開發(fā)、自然資源的充分利用和農(nóng)業(yè)生產(chǎn)的可持續(xù)發(fā)展也有極大的促進(jìn)作用。綜合來說,蔬菜?甘蔗||大豆→綠肥?早稻?晚稻模式是適合我國(guó)鄱?
Abstr:The study aimed to build sustainable application of evaluation index systems and methods and to select sustainable rotation patterns of multi-cropping with high efficiency green in the Poyang Lake Eco-Economic Zone. We conducted two consecutive years of field experiment and used a comprehensive index method to evaluate ecological and economic benefits of different rotation patterns of multi-cropping system in paddy fields. Based on the price of late rice, the results showed that crop yield of vegetables-sugar cane||soybean was the highest, followed by that of milk vetch-early rice-late rice and that of faba bean-early rice-sweet potato||maize the lowest. In 2012, the order of the overall efficiency index was vegetables-sugar cane||soybean 〉rapeseed-maize||soybean-late rice 〉faba bean-early rice-sweet potato||maize 〉milk vetch-early rice-late rice 〉winter fallow-early rice-late rice. This suggested that ‘vegetable-sugar cane||soybean' intercropping pattern made rice production more economical as paddy fields supported high-yields with high efficiency. It was conducive for sustainable development of agricultural production. After multi-crop rotation, the order of the overall efficiency index for 2013 was milk vetch-early rice-late rice vegetables-sugar cane||soybean rapeseed-maize||soybean-late rice faba bean-early rice-sweet potato||maize winter fallow-early rice-late rice. The ‘milk vetch-early rice-late rice' cropping pattern well accounted for the three main benefits conducive for sustainable agricultural production. Based on comprehensive benefits of the two-year experimental results, ‘vegetables-sugar cane||soybean → milk vetch-rice-rice' cropping pattern had the highest efficiency and yield. It well accounted for social, ecological and
