Abstract: In order to reduce excessive irrigation and fertilization in cabbage cultivation, field experiment was conducted to study water and nitrogen utilization and leaching in different water- saving irrigation modes, irrigation and fertilization amount. The result showed that the highest yield of cabbage was 57135 kg/hm2, obtained in mulched drip irrigation and application of nitrogen 300 kg/hm2. The water utilization efficiency in mulched drip irrigation was significantly higher than that in the treatment of ridge cultivation with mulched irrigation. And water utilization efficiency was the highest when the application of nitrogen was 300 kg/hm2. The nitrogen utilization efficiency in mulched drip irrigation was higher than that in the treatment of ridge cultivation with mulched irrigation. The amount and depth of nitrogen leaching in ridge cultivation with mulched irrigation were higher than that in the treatment of mulched drip irrigation. After the harvest, the content of mineral nitrogen in the 200 cm soil layer ridge with the treatment of cultivation with mulched irrigation was higher compared with mulched drip irrigation.
