| 摘 要： | 本研究是在田间试验和土壤、植株实验室大量分析结果基础上完成的。通过连续三茬的磷肥后效试验 ,弄清了小麦施用不同量级磷肥条件下 ,磷肥首季利用率的变化及后季作物对前茬残留磷肥的利用状况。为适当降低或隔茬施用磷肥 ,实行测土调控施磷 ,合理利用磷肥资源提供科学依据。 |
| 关 键 词： | 小麦 磷肥后效 利用率 |

| Abstract: | This study is based on the results of laboratory soil and plant testing and two residual effects of phosphorus field experiment on three crops. The result showed that the change of phosphorus use efficiency at first crop and the residual phosphorus use by successive crops under different rates of phosphorus fertilizer. Provide scientific basis for suitable reduction or alternate crops for application phosphorus and formulate soil test to regulate the phosphorus application for rational use of phosphorus resources. |
| Keywords: | Wheat phosphorus fertilizer residuary efficiency use efficiency |
