| 摘 要： | 通过对苏南次生栎林土壤磷的固定及其抑制技术和需磷量的研究，表明栎林土壤对磷的固定作用强，磷的固定最大，固定率高，腐殖酸能在一定程度上抑制土壤对磷的固定作用，有利于增加肥效，提高磷肥利用率，根据土壤磷素固定状况探讨土壤磷肥需要量，合理施用磷肥具有一定意义。 |
| 关 键 词： | 栎木 土壤 磷肥 固定作用 抑制技术 合理施肥 |

| Abstract: | This paper focuses on the phosphate immobilization and its inhibition as well as fertiphos requirement of the soil under oak stand.The main results show that the immobilization of the soil is so strong that a large of phosphorus is immobilized and the immobilization ratio is high.Humic acid has an effect of inhibition on phosphate immobilization to a certain extent,and it can increase the fertiphos utilization efficiency.Results also show that the fertiphos requirement of the soil can be predicted according to the property of phosphorus immobilization,and it,therefore,is important for rational application of fertiphos. |
| Keywords: | Soil Fertiphos Immobilization Inhibition Rational application of fertiphos |
