摘　　要：通过少免耕栽培与常规栽培对比试验,分析少免耕栽培方式对水稻产量和经济效益的影响。结果表明:与常规栽培相比,少免耕栽培能缩短水稻生育期,使成熟期提前;穗长较长、穗总粒数和实粒数较多;在收获时成熟度不一致的情况下,产量虽较低,但经济效益较高,每667 m2增收10%以上。The test analyse the influence of the yield and economic benefits with reduced tillage on inbred rice and hybred rice,throuth contrast experiment of reduced tillage and conventional planting.Compared with conventional planting,the result showed that it can shorten the growth period of rice,make maturity in advance;longer ear length,much more total grain number and effective grain number per panicle;under the inconsistent maturity circumstances,the yield is lower,but net income per acre is higher,increase income above 10%.
