摘　　要：试验以园土为对照,对盐碱地上桑树"大十"的叶片和果实的营养成分进行了分析。结果表明:盐碱土中桑果和桑叶维生素C和蛋白质的含量均显著高于对照,其中桑果中维生素C的含量为对照的3.67倍,蛋白质的含量为对照的1.48倍。盐碱土中桑果大部分矿质元素的含量均高于对照,其中P的含量是对照的2.06倍;桑叶中的微量元素均低于对照,其中Fe和Mn的含量与对照差异显著。盐碱土中桑果必需氨基酸的含量是对照的1.56倍,总氨基酸的含量是对照的1.53倍;而桑叶中必需氨基酸与总氨基酸的含量均明显低于对照,分别是对照的65.30%和80.26%。两种土壤中桑果和桑叶必需氨基酸占总氨基酸的比例相差不大,均在40%左右。Taking the garden soil as control,nutritional components of mature leaves and fresh fruit of mulberry ＂Dashi＂ was analyzed under saline soil.The results indicated that the contents of vitamin C and protein of mulberry fruit and leaves in saline soil were higher significantly than those of control.In mulberry fruit,the content of vitamin C was 3.67 times,and protein was 1.48 times as control.The contents of most mineral elements in mulberry fruit were all higher than control,and P was 2.06 times as control.In mulberry leaves,the contents of trace elements were all lower.Compared with control,Fe and Mn showed significant difference.The content of essential amino acid in mulberry fruit was comparison 1.56 times,and the content of total amino acid was 1.53 times.In mulberry leaves,the contents of essential amino acid and total amino acid were both lower obviously than control.Under garden soil and saline soil,the proportion of essential amino acid in total amino acid in mulberry fruit and leaves had not been significant difference,were all about 40%.
