| 摘 要： | 以西蒙5号玉米品种为材料,在播期相同的条件下,对不同种植模式的玉米子粒灌浆进程进行了测定比较。结果表明:玉米子粒最终的百粒干重为单种玉米麦套玉米;玉米子粒开始灌浆的日期为单种玉米早于麦套玉米;平均灌浆速率为麦套玉米单种玉米;最大灌浆速率为单种玉米麦套玉米,但出现的时间麦套玉米早于单种玉米;8月中旬后期单种玉米灌浆速率高;8月中旬前麦套玉米的灌浆速率高。

| Abstract: | Using Simon No.5 corn cultivars as the materials, corn grain filling process with different planting modes were de-termined and compared under the same sowing time conditions. The results showed that the final dry weight of the grains of the singly-planted corn was greater than that of the corn interplanted with wheat. The date of start of the grain filling of the singly-planted corn was earlier than that of the corn interplanted with wheat. The average filling rate of the corn interplanted with wheat was greater than that of the singly-planted corn. The maximum filling rate of the singly-planted corn was greater than that of the corn interplanted with wheat, but the occurrence time of the corn interplanted with wheat was earlier than that of the singly-planted corn. The filling rate of the singly-planted corn in late mid August was higher and the filling rate of the corn interplanted with wheat was higher in early mid August. |
