摘　　要：以江西省广昌县莲田土壤为研究对象,测定了6个主产乡镇莲田土壤中、微量元素养分的含量,进行养分丰缺性评价,分析其空间变异特征。结果表明,土壤交换性钙、交换性镁含量分别为834±493、88.4±22.4 mg·kg^(-1),有效硫、有效硼含量分别为28.9±12.4、0.19±0.09 mg·kg^(-1),有效锌、有效铜含量分别为6.42±3.09、5.02±2.41 mg·kg^(-1),有效铁、有效锰含量分别为529±120、71.5±31.1 mg·kg^(-1),有效钼含量为0.12±0.19 mg·kg^(-1)。土壤交换性钙、交换性镁和有效硫等中量元素的含量均较低,其中以交换性镁的缺乏最突出;微量元素中有效硼和有效钼的含量较低,有效锌、有效铜、有效铁和有效锰的含量总体上较高,铁和锰过量的问题应引起重视。根据中、微量元素的空间变异特征,在驿前镇子莲产区要重点关注土壤有效钙、镁的缺乏和铁、锰过量的问题;在头陂镇和盱江镇子莲产区,需重点关注土壤有效硫、硼的缺乏问题。This paper took soils from lotus fields in Guangchang County of Jiangxi Province as research object;measured the contents of medium and trace element contents of lotus field soils from 6 main production villages and towns;evaluated their nutrient abundance and deficiency;and analyzed their spatial variation characteristics.The results showed that the contents of exchangeable calcium(ex.Ca)and exchangeable magnesium(ex.Mg)were 834±493 mg·kg^(-1)and 88.4±22.4 mg·kg^(-1),respectively;available sulfur(av.S)was 28.9±12.4 mg·kg^(-1),available boron(av.B)was 0.19±0.09 mg·kg^(-1),respectively;available zinc(av.Zn)and available copper(av.Cu)were 6.42±3.09 mg·kg^(-1)and 5.02±2.41 mg·kg^(-1),respectively;available iron(av.Fe)and available manganese(av.Mn)were 529±120 mg·kg^(-1)and 71.5±31.1 mg·kg^(-1),respectively;available molybdenum(av.Mo)content was 0.12±0.19 mg·kg^(-1).The contents of ex.Ca,ex.Mg and av.S in lotus field soils were all lower.Among them the lack of ex.Mg was the most prominent.In trace element,the contents of av.B and av.Mo were very lower,whereas the contents of av.Zn,av.Cu,av.Fe and av.Mn were generally higher.Attention should be paid to the excessive contents of av.Fe and av.Mn.According to the spatial variation characteristics of medium and trace elements,in Yiqian Town seed lotus producing area attention should be paid to the lack of ex.Ca and ex.Mg and excessive av.Fe and av.Mn in soils.In Toupi Town and Xujiang Town seed lotus producing area,attention should be paid to the lack of av.S and av.B in soils.
