Abstract
The study aimed to discuss the physiological responses of broccoli to water and fertilizer coupling to find the optimum water and fertilizer treatments.A field experiment was carried out to study the effects of different water and fertilizer coupling on cell defense enzyme and yield.In harvesting period,the root volume of broccoli was the best in the middle water and fertilizer combination and the low water and fertilizer.Low fertilizer was better than high fertilizer and middle fertilizer combination SDO,POD and MDA in broccoli increased with the advancement of reproductive period.Fertilizer had greater influence on content of SOD,at low level treatment,SOD content was lower.In contract,POD in low fertilizer level was higher than high and middle level.At rosette stage,MDA content of F2W2 was the lowest,and less than F3W2,F3W3,F4W1 by 7%,6.8%and 4.8%.F2W2 and F3W2treatments had is the optimum effect,reached1 936.25kg/667m2 and 1929.25kg/667m2,which were higher than F4W3 by 49.8% and 50.3%.Middle water and fertilizer resulted in the maximum yield and cell defense enzyme activity.It is suggested that middle water and fertilizer treatments satisfy the plant growing and bring to bear water and fertilizer cou-pling effectiveness.
