Abstract: Abstract：Surface soil acidification is an important factor limiting the improvement of vegetable yield and quality．The application of soil amendments and organic fertilizers is an eff ective measure to alleviate soil acidification．In this study，control treatment，silica-calcium-potassium-magnesium soil conditioner treatment and shell powder conditioner treatment were designed to select acid soil amendments in Haiyang，Shandong Province by fi eld experiments．On this basis，control treatment，chicken manure source，cow manure source and vermilion waste source organic fertilizers were designed to reveal the eff ects of diff erent soil amendments and sources of organic fertilizers on the yield and quality of greenhouse tomatoes，and provide theoretical basis for further optimizing fertilization，improving soil，and increasing tomato yield and quality．The results indicated that the greenhouse surface soil of Jiaodong Area showed a tendency of acidification，and the pH decreased by 0.06 units. Compared with the traditional control treatment，the application of soil conditioner with silica-calcium-potassium-magnesium could increase the yield of tomato averaged by 12.9%，which was related to the increase of fruit diameter and single fruit weight of tomato．The content of VC in tomato fruit was increased by 15.0% and 12.2% by silica-calcium-potassium-magnesium soil conditioner and shell powder conditioner，respectively．On the basis of the application of silica-calcium-potassium-magnesium soil conditioner，organic fertilizer from chicken manure and vermicelli waste could signifi cantly increase tomato yield averaged by 15.4% and 17.8%，which was related to the increase of tomato plant height，fruit diameter and single fruit weight．Organic fertilizer from vermicelli waste could significantly increase VC content of tomato averaged by 14.9%．Correlation analysis showed that soil pH in 0-20 cm soil layer was positively correlated with yield，plant height，fruit diameter，fruit weight and fruit VC content．In summary，the combination of silica-calcium-potassium-magnesium soil conditioner with organic fertilizer from vermicelli waste can alleviate the acidifi cation of the surface soil and increase the yield and fruit quality of tomato.

摘要： 摘 要：设施菜田表层土壤酸化是限制蔬菜产量、品质提升的重要因素，土壤改良剂以及有机肥的施用是缓解土壤酸化的重要措施。通过在山东海阳开展田间试验，设计对照处理、硅钙钾镁土壤调理剂处理、贝壳粉调理剂处理筛选酸性土壤改良剂，在此基础上设计对照处理以及鸡粪源、牛粪源、粉丝废物源3 种不同来源有机肥处理，旨在揭示不同土壤改良剂和不同来源有机肥对设施番茄产量品质的影响，为进一步优化施肥、改良土壤、提升番茄产量品质提供理论依据。结果表明：胶东设施菜田表层土壤有酸化趋势，pH 降低0.06 个单位，与传统对照处理相比，施用硅钙钾镁土壤调理剂可以平均提高两茬番茄产量12.9%，与番茄果径和单果质量的升高有关，施用硅钙钾镁土壤调理剂和贝壳粉调理剂处理的两茬番茄果实VC 含量平均提高15.0% 和12.2%。在施用硅钙钾镁土壤调理剂的基础上，鸡粪源有机肥和粉丝废物源有机肥可以平均显著提高两茬番茄产量，增幅分别为15.4% 和17.8%，与番茄株高、番茄果径及单果质量的增加有关，粉丝废物源有机肥可以显著提高两茬番茄VC 含量14.9%。相关分析表明，0～20 cm 土层土壤pH 与产量以及植株株高、果实果径、单果质量、果实VC 含量显著正相关。综上，硅钙钾镁土壤调理剂配合粉丝废物源有机肥可以缓解设施番茄表层土壤酸化，达到增产提质的目的。
