摘  要:
为了在饲料生产中更安全、科学地使用石粉,试验检测了河南省南阳地区不同色泽的石粉中钙、镁、铅、氟和砷等几种金属的含量,结果表明:白石粉中钙含量最高,红石粉中镁含量最高,灰石粉中铅含量超标。由于南阳石粉不论其色泽如何价格均相同,所以白石粉的性价比更高,更适合用作饲料原料来获得更高的经济效益。

摘  要:
In order to make use of limestone more safely and scientifically,the purpose of this study was to analyze the levels of several metals such as calcium,magnesium,lead,fluorine and arsenic in different colours of Nanyang limestone.The results showed that the level of calcium was the highest in albarium.the level of magnesium was the highest in red,the gray limestone contained heavy metal lead which was above of the standard.Because of the price of Nanyang limestone was the same,no matter what colours they were,it was thus clear that the performance price ratio of albarium was higher,so it was more suitable to feed as raw materials to earn higher economic benefits.
