安徽省土壤有效性微量元素分布研究——Ⅲ.有效锰的含量与分布
0
()
摘要:
对安徽省1400个土壤样品(包括110个剖面)测定了土壤中有效态锰含量,结果表明:全省土壤交换态锰平均为15.6ppm,易还原态锰平均为170.8ppm;土壤表层交换态锰平均为18.3ppm,其中低于3.0ppm样本数占18.6%,易还原态锰平均为158ppm,其中低于100ppm样本数占36%。淮北地区的碱化潮土、黄潮土和部分砂姜黑土交换态锰含量较低。

CONTENT AND DISTRIBUTION OF AVAILABLE MANGANESE IN SOIL OF ANHUI PROVINCE
()
Abstract:
In the present study, 1400 soil samples (110 profiles involved )from Anhui Province were tested for the content of available manganese. Average exchangeable manganese content was 15.6 PPm and reduceable content was 170.8 ppm; average exchangeable manganese in surface soil was 18.3 ppm; of which that below 3.0 ppm takes 18.6%, while average reduceabl manganese was 158 ppm, of which that below 100 ppm accounted for 36%. Alkaline meadow soil, yellow meadow soil, and some shajiang black have low content of exchangeable manganese.
Key words:  Soil,Available manganese.
