微量元素是含量极微的化学元素,其范围一般为n×10~(-4)——n×10~(-3)%,但在草原生产中有着极其重大的生物学作用。牧草的高产稳产,牲畜的健康往往与草地土壤和牧草中存在某些微量元素的缺乏或过多有关。我们对甘肃天祝金强河寒温潮湿草地类中的山地黑钙土,禾本科——莎草科型草地混合牧草以及四只绵羊的混合粪样,分别于六月、九月、十二月三个时期中,用原子吸收光谱分析法,对其所含有的铁、锰、锌、铜、钴、钼等六种微量元素进行了分析。其目的有四:1.了解微量元素的含量,可作为科学地评价当地牧草质量的指标之一;2.可
Trace elements are minor chemical elements, usually in the range of n × 10 -4 - n × 10 -3%, but they play an extremely important biological role in grassland production. High and stable pasture production, livestock health often with the grass and soil grass and some trace elements in the absence of or excessive. We mixed the samples of mountain chernozem, gramineous-Cyperaceae mixed grass, and four sheep in Tian-Zhu Jin-Qiang cold-temperate wet grassland of Gansu Province in June, September, December 3 A period of time, by atomic absorption spectrometry analysis of the iron, manganese, zinc, copper, cobalt, molybdenum and other six trace elements were analyzed. Its purpose is to have four: 1. To understand the content of trace elements can be used as a scientific evaluation of the quality of the local pasture one of the indicators; 2.
