Based on the mutualistic symbiosis relationship of rice and duck,jointed with no-tillage technique,the new no-tillage system of raising duck in paddyfield was formed.In order to provide the scientific and theoretic foundation for ecological assessment and popularization of the system,soil microbe was studied.The results showed that:firstly,the amounts of three kinds of microbe in section has an obvious floristic distribution trend,the upper the more.Especially in 0~5 cm soil,each microbe amounts of the NCD(no-tillage cast-transplanted with duck treatment)was more than the same layer of the NCND(no-tillage cast-transplanted without duck treatment)and the CCND(conventional-tillage cast-tran- splanted without duck treatment).Although the section distribution was that the upper was higher and the nether was lower,among 5~15 cm dust,the amount of each microbe and total amount of all kinds of microbes were both greater than those of the same layer of the NCND and the CCND.Among two different soil horicons,the difference between NCD and NCND with CCND was significant.Secondly,microbe biomass had the same trend too.The sequence was NCD, NCND,CCND.Authors believed that the increase of soil microbe amounts and microbe biomass in NCD was the result of high fertilizer and “zero input” pesticides in this treatment.

在利用稻鸭互利共生的关系的基础上,将免耕技术引入稻田生态系统,形成稻田免耕养鸭技术新体系.从土壤生物学特性方面对免耕稻鸭复合系统生态学特性进行了研究,旨在为评价该系统的生态学功能提供科学依据.结果表明:1) 各处理土壤中三大类微生物数量在剖面中有明显的上高下低的分布趋势,特别是 0~5 cm 土层,NCD(免耕养鸭处理)量高于同层次的 NCND(免耕不养鸭处理)和 CCND(翻耕不养鸭处理).NCD 的剖面分布也是呈现上高下低的格局,但5~15 cm土层中各微生物数量和总数均大于NCND和CCND处理中同层次的微生物数.上下两层土壤中,NCD 与 CCND 和 NCND 的差异均达到极显著水平.2) 土壤微生物量生物量碳依土壤层次的深浅呈现从上到下渐减的趋势,与微生物的数量分布趋势相一致,各处理中微生物生物量碳从大到小的顺序依次为:NCD,NCND,CCND.由此可见,免耕养鸭有利于和土壤微生物数量和微生物生物量碳的增加,这与该处理较高的土壤肥力和水稻生产过程中实现农药、除草剂的“零输入”有关.

This study is aimed at the ecological and economical benefits of the rice-duck ecological management technique with no-tillage through the adoption of field experiment and environmental economic approaches. The results showed that the farmers' control over field weeds was remarkably effective with the application of this technique. In the initial tillering stage and the full tillering stage of late rice, the rice-duck ecological management technique with no-tillage was 100% effective in the prevention of Chilo suppressalis. The incidence rate of Cnephalocrocis medinalis was 48.05% and 93.55% lower, respectively, than that of the no-tillage cast-transplant area without duck. As for the diseased plant ratios of sheath blight in the no-tillage cast-transplant area with duck it showed 48.15% and 38.21% lower, respectively, than that of the no-tillage cast-transplant area without duck. The control of methane emission was apparently effective in the no-tillage cast-transplanted area with duck over the peak period (in the initial tillering stage and the full tillering stage of late rice), when compared with the conventional-tillage cast-transplant area without duck, showing a reduction of 4.723g/m~2. In comparison with the no-tillage cast-transplant area without duck, the amount of methane emission was reduced 2.333g/m~2. For the total course of late rice, the amount of methane emission in the no-tillage cast-transplant area with duck was reduced 3.37g/m~2 compared with that of the no-tillage cast-transplant area without duck, and reduced 5.59g/m~2 in comparison with that of the conventional-tillage cast-transplant area without duck. No-tillage could save 1300m~3/hm~2 of irrigation water. Analysis of environmental economics indicated: compared with the farmers who adopted the no-tillage cast-transplant without duck technique and those who adopted the conventional-tillage cast-transplant without duck technique,the farmers adopting the rice-duck ecological management technique with no-tillage showed a possible income increase of 2166yuan/hm~2 and 4207yuan/hm~2, respectively. The economic net benefit of the no-tillage cast-transplant with duck technique was 4062yuan/hm~2, and those using the no-tillage cast-transplant without duck technique and the conventional-tillage cast-transplant without duck technique respectively earned 1592yuan/hm~2 and -997yuan/hm~2. The rice-duck ecological management technique with no-tillage might not only bring about the ecological and economic benefits for a compound ecological system with rice-duck, but also may overcome the disadvantages that the no-tillage brings to the ecological environment, thus making it a sustainable agricultural production mode with a potential of promotion and development.

【Objective】The rice-duck ecological system is one of the cream practices from the traditional Chinese agriculture.Study on the effect of reducing methane-emission of this practice could provide theoretical and practical basis for further development and utilization of this classical agricultural technique.【Method】The effect of reducing methane-emission and the economic benefits of rice-duck ecological system were studied by adopting a field experiment and economic methodology.【Result】 The daily variation of CH4 emission in late rice paddy field was basically consistent with the daily variation of air temperature.The highest emission occurred at the full tillering stage of late rice with a rate of 24.1 or 32.2 or 40.5 mg·m-2·h-1 in no-tillage area with duck and no-tillage area without duck and conventional-tillage area without duck,respectively.The inhibition of methane-emission was apparently effective in the rice-duck ecological system during the initial tillering stage and the full tillering stage.Compared to the no-tillage area without duck,methane-emission decreased by 2.333 g·m-2.While compared to the conventional-tillage area without duck,methane-emission decreased by 4.723 g·m-2 growth.During the production period of late rice,the amount ofmethane-emission in no-tillage area with duck was 3.373 g·m-2 less than that of no-tillage area without duck,and 5.59 g·m-2 less than that of conventional-tillage without duck area.The economic significance was analysed.Farmers adopting the rice-duck ecological system obtained 2 166 and 4 207 yuan/ha more income than those who adopted a no-tillage without duck technique or conventional-tillage without duck technique,respectively.In addition to the reduction of the environmental pollution by methane emission,the farmers who adopted the rice-duck ecological system achieved economic benefits of 5 000 yuan/ha,which is 2 206 and 4 274 yuan/ha more than those who adopted a no-tillage without duck technique and a conventional-tillage without duck technique,respectively.【Conclusion】The rice-duck ecological system not only increased the economic benefits of farmers,but also reduced methane emission in rice paddy field A sustainable agricultural production mode is formed.
