Abstract:A consecutive two-year field experiments were carried out to study the effects of mechanical ridging and lateral and band fertilization on the yield and ammonia volatilization in Chinese cabbage production. In 2015, four treatments were designed: Mechanical wide ridging (55 cm) and lateral and band high N fertilization (N480 g/hm2 +MW), mechanical wide ridging and lateral and band low N fertilization (N340 g/hm2 +MW), mechanical narrow ridging (35 cm) and lateral and band low N fertilization (N340 g/hm2 +MN), artificial wide ridging and lateral and band higher N fertilization (N480 g/hm2 +HW). In 2016, four treatments were designed with wide ridging: Artificial ridging without N fertilization (N0+HW), artificial ridging with high N fertilization (N480+HW), artificial ridging with low N fertilization (N340+HW), mechanical ridging and lateral and band low N fertilization (N340+MW). The results showed that the N340+MW treatment had the highest yield of 78.5 t/hm2 , commercial yields of 43.20 t/hm2 and net profit of 30 959 yuan/hm2 , Compared with N480+HW, N340+HW and N0+HW treatments, the N340+MW treatment increased the yield by 8.8%, 15.2% and 58.3% respectively, and increased the commercial yields by 7.4%, 16.4% and 50.1% respectively. Compared with the treatment of N480+HW, the net economic profit of N340+MW and N340+HW were increased by 40.8% and 1.3%, respectively. The ammonia volatilization was 30.0 kg/hm2 in N340+MW treatment, compared with N340+HW and N480+HW treatments, which was significantly decreased by 51.1% and 70.5%, respectively. Therefore, the technology of mechanical ridging and lateral and band fertilization can significantly reduce N fertilizer input and improve cabbage yield, thus can achieve the balance between economic and environmental benefits in Chinese cabbage production.
