| 摘 要： | 综述了红壤上施用磷矿粉对油菜产量、土壤铝毒和土壤化学性质的影响，认为磷矿粉直接施用于酸性土壤上，除增加土壤有效磷含量从而提高作物产量外，还能提高土壤ｐＨ值，增加交换性钙含量和降低交换态铝含量，增加土壤负电荷量，是一种低投入的土壤改良剂，在有条件的地区宜予推广。

| Abstract: | The effects of direct application of ground phosphate rock to red soil onrapeseed yield increase, soil aluminum toxicity and soil chemical properties are discussed. The paper shows that direct application of ground phosphate rock to acid soil can increase soil PH value, the content of exchangeable calcium and the amount of soil negative charge, but decrease the content of soil exchangeable aluminum. Ground phosphate rock can also increase the content of soil available phosphorus, result in the increase of rapeseed yield. These effects indicate that phosphate rock might be a kind of effective and cheap amendment for acid soil, and should be spreaded in suitable regions in future. |
