摘要
盆栽试验和幼苗试验表明 ,土壤中无机磷形态的生物有效性有明显差异 ,其顺序为Ca2 -P >Al-P >Fe -P、Ca8-P >O -P、Ca10 -P 。
The results of a pot experiment and seeding experimnt and soil analysis show that the bio-availabiliy of soil inorganic phosphorus fractions is obvious difference.The order of bio-availability is Ca 2-P>Al-P>Fe-P、Ca 8-P>O-P、Ca 1 0-P,but in different soils'conditions it has a little difference.
