采用土壤农化分析方法结合ICP-AES测定不同种植年限黄蜀葵根际土中的矿质营养元素含量,对比结果显示:随着种植年限的增加,黄蜀葵根际土中常量元素氮、磷及有机质含量逐年下降,土壤酸化;重金属有害元素含量未超过国家农业用地标准,但黄蜀葵根际土中汞元素含量逐年降低。根际土中微量元素锰、锌的含量也逐年降低,而中量元素镁、钠的含量呈上升趋势。其他元素营养成分无规则变化规律或无变化。因此,探究黄蜀葵不同种植年限根际土养分变化规律,为黄蜀葵栽培种植合理使用化学肥料、有机肥和微肥提供理论依据,并为消减黄蜀葵连作障碍提供指导。 Soil mineralogical analysis method and ICP-AES were used to determine the content of mineral elements in rhizosphere soil of Satsuma marshmallow in different planting years. The results showed that the content of nitrogen, phosphorus and organic matter in rhizosphere of satsuma soil increased year by year Decreased, soil acidification; harmful elements content of heavy metals did not exceed the national standard of agricultural land, but mercury in rhizosphere soil of Houttuynia decreased. The contents of trace elements manganese and zinc in rhizosphere soil also decreased year by year, while the content of middle and middle elements magnesium and sodium showed an upward trend. Other elements of the regular changes in nutrients or no change. Therefore, the changes of nutrient content in rhizosphere of yellow hollyhock were explored in order to provide a theoretical basis for the rational use of chemical fertilizers, organic fertilizers and trace fertilizers in the cultivation of hollyhock, and to provide guidance for reducing the succession problems of hollyhock.
