摘  要：
在水分胁迫条件下,结合有机-无机复合型土壤保水剂(SAP)与膜反射型抗蒸腾剂黄腐酸(FA)两种化学制剂,探究联合调控与单一调控下春玉米光合作用的响应规律及其产量驱动机理。试验采用随机区组设计,设置了CK,SAP,SAP+FA,FA 4个处理。结果表明:SAP是调蓄土壤含水量的控制因素,较CK增加12%以上;化控制剂有其有效作用期,SAP作用于整个玉米生育期,而FA在拔节中后期对光合的促进最明显;SAP+FA处理比CK产量增加21.3%,比FA和SAP分别增加9.3%、11.7%,与光合强度呈现出一致性。

摘  要：
Under water stress condition,the response rule of spring maize photosynthesis and yield-driven mechanism was explored with chemical integrated or single regulation technology,combined Superabsorbent polymer( SAP) and Fulvic acid( FA). Randomized block design was set as CK,SAP,SAP + FA,and FA,and each group had three replications. The results indicated that SAP was the major factor to regulate soil moisture content,which had been enhanced by 12% from CK. The chemical reagents had their specific effective durations. SAP played a big role during the entire growth period of maize,while FA promoted photosynthesis mostly during the middle and late jointing stage. SAP + FA ultimately resulted in yield increases of 21. 3%,9. 3% and 11. 7% compared with CK,FA and SAP,respectively,showing an agreement with the photosynthetic efficiency.
