半室技术表明,冲积土壤中水分压力和 CaCO_3含量的增加,使锌和铁的逆扩散系数下降;而土壤容重,周围温度以及合成螯合剂(如 EDTA 和 DTPA)浓度的增加,则提高了锌和铁的逆扩散系数。
Semi-chamber techniques showed that the increase of water pressure and CaCO_3 content in alluvial soil decreased the reverse diffusion coefficient of zinc and iron, and the increase of soil bulk density, ambient temperature and the concentration of synthetic chelating agents (such as EDTA and DTPA) And the inverse diffusion coefficient of iron.
