摘　　要：对晚稻进行了免耕与常耕栽培对比试验。研究结果表明:与常耕栽培水稻相比,免耕水稻的分蘖出现早,茎蘖增长快,分蘖数量多;LAI大,且孕穗期以前LAI增长更快;群体质量优,经济性状好,产量高。The comparative experiments in untilled and conventional culture of late rice were conducted, the results showed that late rice cultivated in untilled paddy had earlier tillering, quicker tiller increment, more tillers, higher LAI, more quickly increasing LAI before booting stage, better population quality and economic characters, and higher yield than late rice cultivated in conventional paddy.
