摘要
本研究选取露地樱桃番茄酸性土壤为试验对象,分别施用复合肥、复合肥-改良液追肥,比较分析改良液配施下土壤pH、阳离子交换量、交换性钙镁和有效铜、锰、锌、铁含量及其在樱桃番茄植株新叶和果实样品中的含量变化趋势,探讨改良液配施对露地酸性土壤、植株和果实中矿物质元素含量的影响。结果表明:改良液配施追肥的试验区土壤pH提升了0.3个单位,复合肥单施追肥的对照区土壤pH下降了0.2个单位;随着改良液施用时间的增加,试验区土壤阳离子交换量和交换性钙含量显著高于对照区,有效铜含量显著低于对照区,对交换性镁、有效锰、锌、铁含量的影响不明显;改良液施用过程中不会产生植株缺素或过量的危害,可以替代部分化肥施用于露地酸性土壤。
The effects of the application of compound fertilizer and compound fertilizer-improved liquid fertilizer on the changes of soil pH, cation exchange capacity, exchangeable calcium and magnesium, available copper, manganese, zinc, iron, plumbum, cadmium, chromium, nickel in the cherry-tomato acid soilwere studied. The application of improved liquid fertilizer could increase the treated plot soil pH, cation exchange capacity and exchangeable calcium significantly compared with the control, and decrease the soil available copper significantly, but had little effects on soil exchangeable magnesium and available manganese, zinc, iron. The improved liquid fertilizer would not produce damage of plant element deficiency or excessive during the fertilization process. It could be used in the Open-air field acid soil instead of some conventional fertilizers.
