通过对阿拉善左旗耕层3663个土壤样品中大量元素、微量元素、速效养分的化验分析,结果表明:大量元素中全氮、速效磷缺乏,速效钾较丰富;微量元素中有效铁、有效锰、有效铜、有效锌、有效硼较丰富,有效钼缺乏;土壤有机质缺乏。因此,在农业生产中,应增施有机肥,施用配方肥,平衡养分,实现增产增收。
Through the laboratory analysis of the trace elements, trace elements and available nutrients in 3663 soil samples from the top of Alxa Left Banner, the results showed that the available nitrogen in available trace elements is deficient in total nitrogen and available phosphorus, while available available potassium is abundant. Manganese, available copper, available zinc, available boron is more abundant, effective molybdenum deficiency; lack of organic matter in soil. Therefore, in agricultural production, organic fertilizer should be increased, the application of fertilizer, balance nutrients, to increase production and income.
