摘要
采用有机肥与化肥配施,研究了有机肥对水稻土根层土壤络合物Fe[Ⅱ]、Mn[Ⅱ]的形成、分布和对微团聚体数量以及根际土壤养分亏缺的补偿,为进一步阐明有机肥的培肥作用奠定基础.
Continous application of organic manure combined with chemical fertilizers to purple paddy soils enhanced the capability of the root-horizon soil of forming chelated com- pounds of Fe and Mn and increased the content of<0.01mm and<0.001mm water stable aggregates of the soil,thus improving rhizosphere nutrition of N,P and K to the plants.
