Abstract: Taking solid and liquid organic fertilizers produced by hydrothermal cracking process as experimental materials, and adopted field plot experiment method to investigate the effects of hydrothermal cracking organic fertilizer and chemical fertilizer on the growth, quality and soil physicochemical properties of greenhouse cabbage, in order to provide reference for the agricultural utilization of organic fertilizer produced by hydrothermal cracking process.The results showed that compared with single application of chemical fertilizer, mixed application of solid or liquid organic fertilizer and chemical fertilizer could significantly promote the growth of cabbage plant and leaf, and the cabbage yield increased by up to 14.9%,showing a good effect of increasing the efficiency of chemical fertilizer.At the same time, compared with single application of chemical fertilizer, application of solid or liquid organic fertilizer could significantly increase the vitamin C content of cabbage, reduce the nitrate accumulation by more than 6%,and improve the quality and storage resistance of cabbage.In addition, liquid organic fertilizer could quickly increase soil organic matter content and activate phosphorus, and the soil organic matter and available phosphorus content increased by 23.8% and 13.1% respectively after mixed application with chemical fertilizer.Therefore, mixed application of solid or liquid organic fertilizer produced by hydrothermal cracking process and chemical fertilizer was an effective way to promote the yield and quality of greenhouse cabbage and improve soil environment.
