摘  要：
以长治市襄垣县韩村蔬菜大棚土壤为研究对象,用原子吸收分光光度计对来自20座蔬菜大棚的180个土壤样品进行有效钙、有效锌含量检测,在了解大棚土壤的基本营养状况下,对蔬菜的种植、施肥提供指导意义。结果表明,大棚土壤有效钙含量增加,有效锌含量也会增加,且二者之间存在正相关关系,但其线性关系并不显著;试验样地内钙含量缺乏,锌明显偏高,并且随着土层深度的增加,金属元素含量呈现逐渐增加的趋势,在上层(0~40cm)变化幅度较大,但仍表现为底层(40~60cm)的金属元素含量大于上层;同时应选择种植吸收土壤有效锌较多、吸收有效钙较少且耐碱性的蔬菜作物。

摘  要：
In this paper, from the soil of the vegetable greenhouses in the Han village Xiangyuan county, Changzhi as the research object, 180 soil samples from each of the 20 vegetable greenhouses were collected and atomic absorption spectrophotometer was used to detect the available content of Calcium and Zinc for basic nutrition condition of greenhouses soil to provide recommendation for vegetable planting and fertilization. The results show that, in greenhouses soil when available calcium content increases, the zinc content also increases, there is positive correlation between them, but its linear relationship is not significant. For the soil sample calcium content is short but zinc is definitely too high. And with the increase of soil depth, the metal element content shows a trend of gradual increase, in the upper layer of 0-40 cm the change is bigger, but still show the underlyer 40-60 cm element content is greater than the surface. At the mean time, Zn more effective absorption, less calcium absorption, alkali resistance vegetable crops are recommended to grow.
