Abstract:: Taking green pepper variety of ‘35-619’ as material，by drip irrigation experiment of Barrel-planted peppers in a greenhouse in both autumn and winter，the water sensitivity index and water production function of green pepper at different stages was obtained through multiple linear regression method based on 2-year test datum，adopting Jensen Model.Furtherly，compiling optimization program by C#.net language，drip irrigation regime of green pepper was optimized by using the genetic algorithm with the goal of maximizing the relative production.The results showed that drip irrigation water of green pepper dripping its whole growth period in a greenhouse in both autumn and winter was 190 mm with the highest water production efficiency.
