| 为进一步提高蔬菜作物间套复种的经济效益，采用田间小区试验，研究甜玉米与蔬菜间套复种的8种种植模式的产值效益。结果表明：甜玉米与不同蔬菜间套作的总产量和总产值均高于蔬菜单作；其中，2004年2∶4带型处理年总产值最高，平均比单作增加49.1%；2005年夏播模式2行甜玉米‖4行甘蓝/4行莴笋（2∶4带型）的经济效益均高于其它处理，其作物总产值达到67 377 元·hm-2，比当季蔬菜单作增加96%；2005年甜玉米间作蔬菜（2∶4带型）的秋播模式2行萝卜‖11行大蒜/2行莴笋模式总产值达64 667 元·hm-2，比蔬菜单作增加161%，其年总产值比蔬菜单作平均增加299.5%。说明甜玉米与不同蔬菜间套作有利于提高农作物的经济效益，而2∶4带型的
种植模式可在蔬菜农业生产中推广应用。 |

| Abstract: |
| In order to improve the benefits of vegetable intercropping and multiple cropping, this experiment was conducted to compare the production value of eight patterns on sweet maize and intercropping. The results are as follows: the total income and yield of sweet maize and vegetable intercropping are higher than vegetable monocropping. The total income of the pattern(2∶4) was the highest in 2004, and was increased by 49.1% on average than vegetable monocropping. The total income of the pattern (2 rows of sweet maize ‖4 rows of cabbage / 4 rows asparagus lettuce) was 67 377 yuan·hm-2 in 2005, which was the highest income of crop sowing in summer. It has been increased by 96% as compared to the vegetable monocropping in same season. The total income of the pattern (2 rows of garden radish ‖11 rows of garlic / 2 rows of asparagus lettuce) was 64 667 yuan·hm-2 in 2005, which was the highest income of crop sowing in autumn. It had been increased by 161% in comparison with the vegetable monocropping, and its annual total income was increased by 299.5% than
monocropping. In conclusion, maize and vegetable intercropping can increase the yield and output of intercropping and rotation, and the patterns of 2∶4 are recommended for vegetable production. |
