摘要
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。
Vegetables of Yuzhong district was selected as research object,waste mineral nutrients of mainly solanaceae vegetable were measured and analyzed.The results showed that,solanaceae vegetable stubble moisture content was between 75%-90%;stubble all contained large amounts of nitrogen,phosphorus,potassium,which N,P,K content of solanaceae plants in greenhouse were higher than that in the open field,and nitrogen and potassium concentrations were higher than the phosphorus content;total carbon content in the open field of eggplant was the highest,cellulose content reached 4.71%in greenhouse peppers,lignin reached the highest level in open field eggplant.The same economic factors commodities also reflected the economic level of vegetable waste and commodities.
