Abstract: Production technology mode of rice-rape using mechanical and simple method was studied according to the restricting factors of rape planting in Chongqing city.This technology mode was applicable to an altitude of 200~800 m of shallow hilly and flatland in low mountain and hill in Chongqing.After harvesting and discharging water of previous crop of rice，before cloudy or rain，rape seeds were direct seeded using no tillage or shallow tillage machinery during September 20th and October 20th.Easy and simple production of rice and oil rape rotation by mechanization was realized.It could greatly reduce labor cost，improve production efficiency of rapeseed.Core of this technology mode was simple seeding，increasing nest encryption，controlling nitrogen and increasing phosphorus and potassium，early fertilization，promoting seedlings and grass pressing.The goal of achieving the switching output and benefit according to quantity and efficiency was realized.
