摘　　要：通过对各类土壤矿质营养及桑叶中各元素测定得知，桑叶中各元素含量受所在土壤各元素含量制约；优质类土壤生产的桑叶中，钾、钙、镁及微量元素总量均明显高于其他桑叶，但优质类土壤中各矿质元素含量也有丰缺，故应针对性施肥调节；普通桑园要在加强氮、磷肥施用的同时，注意配施钾、钙、镁、锰、硼等肥。The detemrination of mineral nutrients in various soils and elements in mulberry leaves showed that the levels of mineral elements in mulberry leaves were controlled by their levels in soils where the mulberry planted. The contents of K,Ca,Mg and microelements in leaves of mulberry grown on quality soil were significantly increased.However,even in quali-ty soil5,.some mineral nutrients could be inadequate,and should be supplemented by ferti-lizing.In common mulberry fields,K,Ca,Mg,B and Mn are to be applied in addition to N and P fertilizers.
