摘　　要：对酸性红壤改良橙缺锰植株土施及叶面喷布硫酸锰均可明显地提高植株锰含量，促进枝梢生长与结果。土壤施锰可明显地提高土壤代换态锰及易还原态锰含量，有效地改善缺锰红壤柑桔园的土壤与树体锰素水平。可在盛果期每株年施硫酸锰０．２５ｋｇ，亦可在春夏季叶面喷布０．２％～０．４％硫酸锰。The present experiment was conducted in 1993～1994 in Nanjing County ofsouth Fujian to study the effects of soil and foliar application of manganese sulphate on thecorrection of Mn deficiency in ‘Gailiangcheng’orange trees during full fruit peroid.Theapplication of manganese sulphate on soil and foliage had a certain effect on the increasingmanganese content in leaves,the growth of shoots and yield.Soil application of manganesesulphate increased the contents of exchangeable Mn and easily reducible Mn in soil.TheMn deficiency disease was cured by manganese sulphate,The before,the authors recom-mend an application of 0.5 kg/tree per year in the orchard,and 0.2%～0.4%MnSO4 for foliar spraying in spring and Summer.
