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。
A 16-year-old Korla fragrant pear tree was used as experimental material to analyze the effect of formula fertilizers on the changes of mineral nutrient content in pear and soil for two consecutive years. The results showed that the contents of mineral nutrients in pear fruits increased with different degrees in one year of formula fertilization. Under the same fertilization years, the contents of mineral nutrients, N, K, Ca and Zn in the fruits of formula fertilization 2 were the highest, P The contents of formula fertilizer 2 and formula fertilizer 3 were not significantly different. The formula fertilization for 1 year showed that the contents of alkaline N, available P, available K, exchanged Ca and Mg in soil increased with different degrees. , The content of mineral nutrients in soil generally increases. Formulation fertilization can increase the content of nutrients and soil nutrients, of which the formula fertilization 2 years effect is obvious. There are significant differences among the treatments. The effects of fertilization are as follows: Formulation and fertilization 2> Formulation and fertilization 3> Formulation and fertilization 1> CK.
