| 摘 要： | 针对一些地区种植作物一季有余、两季不足的自然资源情况，提出了一种新型种植模式。即上茬种植鲜食玉米，下茬种植以营养体为收获对象的青贮玉米。通过随机区组试验，筛选出垦粘1号为上茬鲜食玉米首选品种，郑单958为下茬青贮玉米首选品种。两茬可获得鲜穗16.34 t/hm2，鲜秸秆103.3 t/hm2。这种复种模式有利于解决畜牧业发展带来的饲草短缺的现实难题，是适应当前农业产前结构调整的有益探索。 |

| Abstract: | A new pattern of multiple cropping was studied for some areas where heat resource is excess for planting once but deficient for planting twice in effective growing season. In this pattern fresh food corn is planted for previous cropping and silage corn aiming to harvest fresh yield is planted for the aftercrop. It is concluded by the design of randomized blocks that Kennian No.1 is the first fresh food corn variety for previous cropping and Zhengdan958 is the first silage corn variety for the aftercrop. The pattern of Kennian No.1- Zhengdan958 can provide 16.34 t/ha fresh weights of ear, 103.3 t/ha fresh weights of stalk. Moreover can solve the problem of shortage of feed caused by the development of animal husbandry. It will befit agricultural industrial structure adjustment. |
