摘要: 应用常规化学分析方法测定了白菜、圆白菜、芹菜、大葱、茼蒿、茴香菜、小油菜、辣椒、柿子椒、胡萝卜、蒜苗、四季豆、马铃薯13种蔬菜采后残体的化学组成含量,为蔬菜残体的资源化高效利用提供依据。结果表明,蔬菜残体的水分含量范围为77.16-96.83%;蔬菜残体的C/N值在8.3-18.6之间。大量元素(氮、磷、钾)的总含量(以烘干基计算)最高的是马铃薯7.18%,最低的为白菜3.91%;中量元素(钙、镁)总含量最高的是茴香菜2.24%;必需微量元素(铜、锌)总含量最高的是圆白菜5.87mg/kg。马铃薯和胡萝卜残体中重金属铬含量有超标现象,分别占总样本的33.3%和11.1%,而镉含量在蔬菜残体中未有超标。

Abstract: The chemical constituents of residues from cabbage, head of cabbage, celery, scallion, crowndaisy chrysanthemum, foeniculum, pakchoi, pepper, sweetbell pepper, carrot, garlic bolt, green bean and potato were determined in order to provide the basis for resource efficient utilization of vegetable residues. The results showed that in vegetable stumps the moisture content was 77.16- 96.83%, The C/N rate of vegetable residues was 8.3-18.6. The highest dry weight contents of major elements(N, P and K) were 7.18%(potato), the minimum was 3.91%(cabbage).The highest contents of middle elements (Ca, Mg) were 2.24%(foeniculum). The highest contents of micro elements (Cu, Zn) were 5.87mg/kg(head of cabbage). 33.3% and 11.1% of the samples whose chromium content of potato and carrot exceeded the standard, the cadmium content in vegetable residue did not exceed the standard.
