In this paper, several kinds of foliar fertilizer in vegetables production effect comparison test screening. The same amount of water as (CK). Tomato spraying Gao Le; (CK) increased 13.07%, the net added value of 7757.20 yuan / hm2; Gaole; (CK) increased 13.99%, the net added value of 8391.78 yuan / hm2; Gaole Ⅰ increased (CK) 16.9%, net added value 7941.00 yuan / hm2, Gaole Ⅱ increased (CK) 18.0%, net added value 10309.20 yuan / hm2; , Ⅱ increased by 12.2% and 16.9% respectively compared with CK, the net added value was 4090.80 yuan / hm2 and 5662.80 yuan / hm2, respectively; and the other foliar fertilizers also had different degrees of increase However, the average yield of high I and II were both 10.26% lower, of which the chemical fertilizers and the bumper were 12.54% lower.
