| 摘 要： | 通过室温培养-盆栽试验研究了施用海藻提取物对石灰性土壤无机磷组分和有效磷的影响,有效磷和无机磷分级测定结果表明,两种海藻提取物能够提高土壤中有效态Ca2-P和A l-P含量和有效磷含量,对Fe-P有降低趋势,对O-P无明显影响。

| Abstract: | The room-temperature culture and pot experiment were carried out to study the changes of inorganic P fraction and available P content in calcareous soils after the application of seaweed extract.The results showed that the two kinds of seaweed extract increased the contents of Ca2-P,Al-P and available P in calcareous soil,decreased the content of Fe-P,while had no obvious effect on O-P. |
