In order to explore the effect of pomace biochar on the yield and quality of Chinese cabbage and soil properties and realize the resource utilization of pomace, a pot experiment was conducted to study the effect of 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 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 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 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 pomace biochar can significantly increase the yield and quality of Chinese cabbage and improve soil properties. The preparation of pomace into biochar can provide a theoretical reference for the rational utilization of pomace resources.
为探究果渣生物炭对小白菜产量和品质以及土壤性质的影响，实现果渣的资源化利用，通过设置0%（CK）、1%（T1）、3%（T2）、5%（T3）和7%（T4）五个生物炭施用量水平进行盆栽试验，研究果渣生物炭对小白菜产量和品质以及土壤性质的影响。结果表明：①施用果渣生物炭能显著提高小白菜的产量和品质，生物炭施用量为5%时效果最佳。与CK相比，小白菜的产量、可溶性固形物、可溶性糖、维生素C、全氮、全磷和全钾含量分别提高了71.51%、40.14%、33.65%、38.08%、9.03%、28.85%和35.38%。②施用果渣生物炭能显著改善土壤性质，提高土壤养分含量和有效性。生物炭施用量为5%时效果较好。与CK相比，土壤pH值、有机质、全氮、碱解氮、有效磷和速效钾含量分别提高了41.06%、134.84%、157.48%、140.79%、341.75%和627.13%。有效铁、锰、铜、锌以及交换性钙、镁含量分别比CK提高了37.68%、61.69%、400.00%、4648.84%、617.17%和351.42%。③施用果渣生物炭能显著提高土壤酶活性。与CK处理相比，土壤脲酶、酸性磷酸酶、过氧化氢酶和蔗糖酶分别提高了51.43%-362.86%、90.63%-134.14%、21.40%-85.12%和82.92%-218.43%。④冗余分析表明，土壤速效钾、交换性钙、土壤有机质和有效磷以及有效锌是影响小白菜产量和品质的主要因素，且它们之间存在显著正相关。综上所述，施用果渣生物炭能显著提高小白菜的产量和品质，改善土壤性质。将果渣制备成生物炭可为果渣资源的合理利用提供理论参考。
