Seasonal change characteristics of alkaline hydrolysis nitrogen and total nitrogen in typical Calamagrostis angustifolia wetland soils of Sanjiang Plain
Two typical soils(meadow marsh soil and humus marsh soil),located in different moisture zones in Calamagrostis angustifolia wetland of Sanjiang Plain,were selected as study objects,and the seasonal change characteristics of alkaline hydrolysis nitrogen(K-N) and total nitrogen(TN) contents in them were contrastively studied.Results showed that the seasonal change characteristics of K-N and TN contents in different layers of the two typical soils were significantly different.The changes of K-N contents in 0-5...
