摘  要：
为了提高土地利用率,通过饲草大麦复种育苗食用向日葵试验,综合分析两季作物的产量和效益,从而得出适宜河套灌区双季种植模式.结果表明:前茬饲草大麦12PJ-051平均产量729.44 kg/667 m~2,粗蛋白含量10.24%~11.8%,符合优质牧草的标准;复种的育苗食用向日葵JK601,平均产量240.45 kg/667 m~2;2季合计收入2 944.82元/667 m~2,纯收益2 064.82元/667 m~2,可实现增产、增收,适宜在河套灌区推广种植,对调整本地区种植业结构具有十分重要的意义.

摘  要：
The objective of this study was to establish a suitable double-cropping system of planting edible sunflower after forage barley in Hetao Irrigation Area in Inner Mongolia, thus improving land use efficiency. A field experiment was performed, in which seedlings of the edible sunflower cultivar JK601 were transplanted after harvesting plants of the forage barley cultivar 12 PJ-051, and their yields and resulting economic benefits were comprehensively analyzed.As a result, the average yield of barley plants(the previous crop) was 729.44 kg/667 m~2,and their crude protein content was 10.24%～11.8%, which meets the standard of high-quality forage grass. The average yield of sunflower was 240.45 kg/667 m~2. Consequently, the total income of the two-season crops was 2 944.82 yuan/667 m~2 and the net income was 2 064.82 yuan/667 m~2, demonstrating that this double-cropping system can increase crop yields and the income of farmers. Hence, the established double-cropping system of planting edible sunflower after forage barley is suitable for promoting in Hetao Irrigation Area, which has significant implications for adjusting the structure of planting industry in this area.
