摘　　要：为研究硅肥施用方式和浓度对青脆李果实品质的影响,以青脆李为试材,对其进行硅肥的根部灌溉和叶面喷施。结果表明,硅肥的不同施用方式和浓度均能明显提高青脆李单果重等外观品质和可溶性固形物含量、总糖、可滴定酸和维生素C等内在品质,在谢花后和膨果期叶面喷施硅肥600倍液效果最好,在萌芽前、谢花后和膨果期根部灌溉0.35 kg/株效果次之。叶面喷施能够更直接地为果实提供所需的硅元素,促进果实的发育和品质提升。To study the effects of different application methods and concentrations of silicon fertilizer on the quality of plum‘Qingcui’,plum‘Qingcui’was used as the test material,and silicon fertilizer was applied through root irrigation and foliar spraying.The results indicate that different application methods and concentrations of silicon fertilizer can significantly improve the appearance quality,such as single fruit weight,as well as the intrinsic quality indicators like soluble solids content,total sugar,total acid,and vitamin C in plum‘Qingcui’.After flowering and during the fruit swelling period,spraying a 600-fold diluted solution of silicon fertilizer on the leaves is most effective.Irrigating the roots with 0.35 kg per plant before budding,after flowering,and during the fruit swelling period is the second most effective method.Foliar application can more directly provide the necessary silicon elements to the fruit,promoting its development and quality improvement.
