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.
