Popis: An incubation experiment was carried out with the addition of litter filtrate, litter residue and alanine at 25 ℃ for 36 days under 60% and 90%WHC (water holding capacity) conditions. The results showed that alanine was rapidly mineralized in soil, and soil NH设置60%和90%WHC两种土壤水分条件,并添加凋落物过滤液、剩余残渣和丙氨酸,进行为期36 d的室内培养(25 ℃),研究了凋落物中水溶性有机物和残渣对土壤氮素转化的影响.结果表明: 在60%和90%WHC条件下,丙氨酸在土壤中迅速矿化,该处理的土壤铵态氮(NH
