The results showed long-effect organic fertilizer (1 500 kg/hm2) was used as the basic fertilizer. Liquid fertilizer was used onetime (1 kg/hm2,thickness 250 times) when two leaf and one heart. Carbamide was used in the period of returning green, tiller, teaseling, and its total quantity was 600 kg/hm2.
