摘要:
以圆叶决明、印度豇豆、大豆、稻秸4种植物物料为试验材料,通过室内培养试验研究它们对茶园土壤酸度的改良效果。结果表明,培养90 d后,添加圆叶决明和稻秸的土壤pH值分别比对照显著提高0.39、0.71(2%添加量)和0.54、0.89个单位(4%添加量),其他处理对pH值的提升不显著。除2%添加量的大豆和印度豇豆处理外,其他处理都能显著降低土壤交换性铝以及交换性酸含量。4种植物物料均能显著增加交换性盐基离子总量以及土壤盐基饱和度,并且4%处理比2%处理的增加幅度更大。只有4%添加水平的大豆和圆叶决明处理能显著增加土壤阳离子交换量,其他处理对土壤阳离子交换量的影响不显著或有所降低。大豆、印度豇豆、圆叶决明(4%添加量)能够显著提升土壤硝态氮含量,2%添加量的圆叶决明处理对土壤硝态氮含量的影响不显著。相反地,稻秸降低了土壤硝态氮含量。综合比较,圆叶决明和稻秸可作为改良茶园酸化土壤的生物材料。
