【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。更多还原

【Abstract】 Using Simon No.5 corn cultivars as the materials,corn grain filling process with different planting modes were determined 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.更多还原
