适宜的品种,是小麦套覆膜玉米带田能否获得高产的关键。如果小麦、玉米品种的生育期过短,则不但不会充分发挥套种的增产作用,而且很有可能造成减产；如果选择品种的生育期过长,不但会因延长共生期而加剧相互间的矛盾,而且还会遭受低温危害以至不能成熟。

The suitable variety is the key to whether wheat can be covered with plastic corn field can obtain high yield. If the growth period of wheat and maize varieties is too short, not only does not give full play to the yield-increasing effect of intercropping, but also is likely to result in the reduction of production. If the growing period of the selected varieties is too long, not only will the contradictions be aggravated by prolonging the symbiotic period , But also endangered by low temperature and can not mature.
