摘要：

In order to explore the effect of Rosa roxburghii pomace biochar on the yield and quality of Chinese cabbage and soil properties and realize the resource utilization of R. roxburghii pomace，a pot experiment was conducted to study the effect of R. roxburghii pomace biochar on the yield and quality of Chinese cabbage and soil properties by setting five biochar application rates of 0%（CK），1%（T1），3%（T2），5%（T3），and 7%（T4）. The results showed that：① The application of R. roxburghii pomace biochar could significantly improve the yield and quality of Chinese cabbage，and the effect was the best at a 5% biochar application rate. The yield，soluble solids，soluble sugar，vitamin C，total nitrogen，total phosphorus，and total potassium content of Chinese cabbage increased by 71.51%，40.14%，33.65%，38.08%，9.03%，28.85%，and 35.38%，respectively，compared with those in CK. ② The application of biochar from R. roxburghii pomace could significantly improve soil properties and increase soil nutrient content and availability. The effect was better at a 5% biochar application rate. The soil pH，organic matter，total nitrogen，alkali-hydrolyzable nitrogen，available phosphorus，and available potassium content increased by 41.06%，134.84%，157.48%，140.79%，341.75%，and 627.13%，respectively，compared with those in CK. The contents of available Fe，Mn，Cu，and Zn and exchangeable Ca and Mg increased by 37.68%，61.69%，400.00%，4 648.84%，617.17%，and 351.42%，respectively，compared with those in CK. ③ The application of biochar from R. roxburghii pomace could significantly enhance soil enzyme activity. Compared with those in the CK treatment，soil urease，acid phosphatase，catalase，and sucrase increased by 51.43%-362.86%，90.63%-134.14%，21.40%-85.12%，and 82.92%-218.43%，respectively. ④ Redundancy analysis showed that soil AK；exchangeable Ca，SOM，and AP；and available Zn were the main factors affecting the yield and quality of Chinese cabbage，and there was a significant positive correlation between them. In summary，the application of R. roxburghii pomace biochar can significantly increase the yield and quality of Chinese cabbage and improve soil properties. The preparation of R. roxburghii pomace into biochar can provide a theoretical reference for the rational utilization of R. roxburghii pomace resources. © 2024 Science Press. All rights reserved.
