摘　　要：以16年生库尔勒香梨树为试材,分析连续2年配方施肥对香梨果实及土壤矿质营养含量变化的影响。结果表明:香梨果实中矿质营养的含量,在配方施肥1年有不同程度的增加;相同施肥年限下,配方施肥2的果实中矿质营养的含量,N、K、Ca、Zn含量最高,P含量配方施肥2与配方施肥3差异不显著;配方施肥1年,各配方处理后土壤中碱解N、速效P、速效K、交换Ca、Mg的含量有不同程度增加;连续2年配方施肥处理,土壤中矿质营养含量有普遍增加趋势。配方施肥处理能提高果实、土壤营养元素的含量,其中配方施肥2年效果明显。各处理之间有着显著差异,施肥效应表现为:配方施肥2>配方施肥3>配方施肥1>CK,配方施肥2年效果最好。Taking 16-year-old Korla fragrant pear as research object,the effect of formulated fertilization on fruit and soil mineral nutrition content in Korla fragrant pear were studied.The results showed that the contents of mineral nutrition increased to different extent in fruit of Korla fragrant pear with one year＇s formulated fertilization;under the same long years＇ fertilization,the contents of N,K,Ca,and Zn were the highest in fruit of Korla fragrant pear using formula 2,and the content of P in fruit of Korla fragrant pear using formula 2were no significant difference with that of Korla fragrant pear using formula 3;for Korla fragrant pear with one year＇s fertilization,the contents of alkaline hydrolysis N,available P,available K,translatable Ca and Mg increased to different extent in the soil after different treatments;for Korla fragrant pear with two consecutive years＇ formulated fertilization,the contents of mineral nutrition in the soil experienced the increasing trends in general.Formulated fertilizations could improve the content of fruit and soil and the effective of formula 2was significant.The founding was that significant differences exist between different treatments,and the order of formulated fertilization effects was as follows：formulated fertilization 2〉formulated fertilization 3〉formulated fertilization 1〉CK.The effective of formulated 2was the best.
