以榆中地区蔬菜为研究对象,主要对茄科类蔬菜废弃物矿质营养元素进行了测定和分析。结果表明:茄科蔬菜残株含水率波动于75%~90%;残株中都含有大量的氮、磷、钾,其中温室栽培的茄科植物的氮、磷、钾含量都高于陆地栽培的茄科植物,并且氮和钾的含量都高于磷的含量;露地茄子的全碳含量最大,纤维素含量最高的温室辣椒达到4.71%,在木质素中,露地茄子的含量最高。同样商品经济系数也反映出了蔬菜废弃物与商品经济效益的高低。
Taking Yuzhong vegetables as the research object, the mineral nutrient elements of Solanaceae vegetable wastes were mainly measured and analyzed. The results showed that the water content of Solanaceae vegetable residues fluctuated between 75% and 90%, and the residuals contained a large amount of nitrogen, phosphorus and potassium. The contents of nitrogen, phosphorus and potassium of solanaceous plants in greenhouse were higher than those of onshore cultivation Of solanaceous plants, and the contents of nitrogen and potassium are higher than the content of phosphorus. The total carbon content of the exposed eggplant is the highest. The highest content of cellulose in the greenhouse pepper reaches 4.71%. In lignin, the content of eggplant in the field is the highest. The same coefficient of commodity economy also reflects the level of economic benefits of vegetable wastes and commodities.
