摘　　要：河套地区从7月3日至10月8日≥10℃活动积温2048.5℃,复种早熟粮饲兼用型玉米由于受光热资源和品种生育期的限制,风险较大。为解决这一问题,引进了冬小麦全覆膜穴播技术,麦收后免耕复种自主培育的生育期在92 d以内的3个特早熟玉米新品系。结果表明,3个玉米品系在初霜冻日来临前干物质含量均能达到青贮玉米的要求,重霜冻日来临前籽粒均能成熟,突破了种植技术难点,是较为高效的复种模式,既增加了粮食产量,也可以作为饲料利用。The accumulated temperature higher than 10℃in Hetao area from July 3-October 8 is 2048.5℃,there is relatively large risk for the precocious grain and forage maize in multiple cropping system due to the restrictions of photothermal resource and the growth period of wheat and maize variety.In order to solve this problem,full plastic film mulching cultivation technology of winter wheat was introduced,and three new early-maturing maize strains with the growth period in 92 days were planted after wheat.The results showed that the dry matter content of the three lines could reach the requirement of silage maize before the first frost day,and all the grains were mature before serious frost daySo the planting technology difficult was break through,and was a more efficient model of multiple cropping,which not only increased grain yield,but also could be used as fodder.
