Abstract: At present,there are many problems in double-cropping rice planting in southeast Hubei province,such as large labor input,tight stubble,long slow seedling stage and insufficient basic seedlings during mechanical transplanting.Through the research on the annual high yield and high efficiency of double-cropping rice,it was found that the double mechanical transplanting cultivation mode of early rice Liangyou287 and late rice Taiyou398 had high yield,short overall growth period and low production risk,the techniques of double cropping rice scale mechanization and double mechanicaltransplanting were integrated and demonstrated.

Key words: double cropping rice, mechanical transplanting, high yield, benefit increasing, planting mode
