亚热带黑麦草─白三叶草地土壤─牧草中微量元素季节动态及分布规律
The Study on Dynamics and Allocation of Trace Elements between Soil and Forage in Pasture of Ryegrass and White Clover in Subtropical Region of China
【摘要】 本文对亚热带人工草地土壤微量元素Co、Cu、Zn和Cr在速效库内的动态、土壤中全量的动态、牧草中的含量动态,以及各流通库的分布进行研究,探明了上述微量元素在牧草中的季节动态,土─草─畜中的分布特点以及酸性或微酸性土壤中的变化规律。
【Abstract】 The dynamics and allocation of trace elements including Co、Cu、Zn and Cr were atudied in siollabile pool,soil total pool,herbage pool of ryegrass and white clover pasture in subtropical mountain region ofChina. The characteristics of Co、Cu、Zn、Cr seasonal changing and allocation were found among soil-herbage-animal.
