摘　　要：以沸石、膨润土、糠醛渣为活化剂 ,研究了不同活化剂对磷矿粉的活化作用。结果表明 :沸石产地不同对同一磷矿粉的增效作用不同 ,且沸石对磷矿粉的活化作用随土壤性质而异 ,在北方含Na+ 较高的盐化潮土上速效磷增加了 182 9% ,膨润土、糠醛渣作为活化剂也可提高磷矿粉中磷的释放。The experiment used zeolite, bentonite, furfural residue as activator to activate phosphate rock. The result showed that different zeolite had different effect to same phosphate rock, the effect of zeolite to phosphate rock was different along with soil properties, the soil available P had increased by 182.9% in northern salinized soil. Bentonite, furfural residue as activators can increase P releasing from phosphate rock as well.
