摘要： 以露地栽培的黄瓜、番茄、菠菜、萝卜为试材,探究了施肥对蔬菜营养组分的影响。结果表明,5种施肥处理中最佳施肥处理为半量虫粪(56250kg/hm2)与50%NPK配施,可显著提高4种蔬菜中Vc、可溶性糖、可溶性Pr、果胶质含量,降低硝酸盐含量及单宁、纤维素含量,从而提高蔬菜营养品质和产量。与单施尿素处理比较,萝卜中Vc含量增加6134%,菠菜中可溶性Pr含量增加587%,黄瓜中糖酸比增加4109%,硝酸盐含量降低9%。

Abstract: Fertilization effect on vegetables nutritious component was studied through trials conducted using cucumber,tomato,spinach and carrot.The results showed that the optimum treatment was the combination of half worm manure(56 250 kg/ha) with 50% NPK,which increased the content of vitamin C,soluble sugar,soluble protein and pectin and reduced the content of nitrate,tanin and cellulose of four kinds of vegetables.Compared with the urea treatment,the content of vitamin C in carrot,soluble protein in spinach and the ratio of sugar and acid increased by 61.34%,5.87% and 41.09% respectively.Meanwhile,the nitrate content reduced by 9%.
