摘　　要：以桑园优质土壤中主要矿质营养的数量及比例为基础，研制了仿优质土壤桑树专用肥料，按照山东省棕壤、褐土、潮土３大类土壤测定肥效，经过３ａ的小区试验、中试及推广，认为该肥能有效地提高桑叶产量并能改进叶质，经济效益较高。Based on the levels and proportion of main mineral nutrients of qualified soil inmulberry fields,the exclusive manure of mulberry field was modelled on the high quality soil.With 3 years oftest,the results showed that the yield and leaf quality of mulberry in the exclu-sive manure was improved effectively.Mulberry leaf production increased 26％、9．6％and13％,and cocoon yield increased 23．2％、12％ and 9．1％respectively in the 3 main soil typeof brown earth,drab soil and damp soil in Shandong province.
