Abstract
Taking ‘Zhongnong No.21'as material,the influence of different water content of substrate in different period on cucumber growth,yield and photosynthetic characteristics in facilities condition were studied.The results showed that the water content in 60%~70% was suitable to vegetative growth,yield and photosynthetic characteristics.Through the regression equation simulation optimization,suitable substrate water content range were 61%~74%,among them,in the early stage of cucumber growth period,the suitable water content was 68%,under this condition had the highest yield of cucumber;in the late stage,the suitable water content was 69%,and had the highest yield.
