中文摘要
      为探明刺梨果渣生物炭对白菜产量及品质和土壤性质的影响,实现刺梨果渣的资源化利用,通过盆栽试验设置5个生物炭施用量:0 %(CK)、1 %(T1)、3 %(T2)、5 %(T3)和7 %(T4),研究刺梨果渣生物炭施用对白菜产量及品质和土壤性质的影响.结果表明,①施用刺梨果渣生物炭能够显著提高白菜产量及品质,在5 %生物炭施用量时效果最佳,白菜产量、可溶性固形物、可溶性糖、维生素C、全氮、全磷和全钾含量较CK分别提升了71.51 %、40.14 %、33.65 %、38.08 %、9.03 %、28.85 %和35.38 %;②施用刺梨果渣生物炭能够显著改善土壤性质提高土壤养分含量及有效性,在5 %生物炭施用量时效果较好,土壤pH、有机质、全氮、碱解氮、有效磷和速效钾含量较CK分别增加了41.06 %、134.84 %、157.48 %、140.79 %、341.75 %和627.13 %,有效Fe、Mn、Cu、Zn含量和交换性Ca、Mg含量较CK分别提高37.68 %、61.69 %、400.00 %、4 648.84 %、617.17 %和351.42 %;③施用刺梨果渣生物炭能够显著增强土壤酶活性,土壤脲酶、酸性磷酸酶、过氧化氢酶和蔗糖酶分别较CK处理提高的范围为51.43 %~362.86 %、90.63 %~134.14 %、21.40 %~85.12 %和82.92 %~218.43 %;④冗余分析表明施用刺梨果渣生物炭后,土壤有效钾、交换性钙、有机质、有效磷和有效锌等是白菜产量及品质变化的主要影响因子,与其呈显著正相关关系.综上所述,施用刺梨果渣生物炭可以显著提高白菜产量及品质,改善土壤性质,将刺梨果渣制备成生物炭可以为刺梨果渣资源化合理利用提供理论参考.
英文摘要
      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.
