摘  要：
为筛选出适宜洞庭湖区种植的高产夏玉米品种,以临奥1号为第一对照,郑单958为第二对照,在常德市安乡县进行了22个夏播品种的筛选试验.在种植密度5.25万株/hm~2条件下,7个品种产量超过对照临奥1号和郑单958,其中登海605、康农669、NK718产量高,综合性状优良,生育期相对较短,收获后不影响后茬油菜播种,适用于洞庭湖区冬油菜-夏玉米模式.

摘  要：
In order to screen out high-yielding summer maize varieties suitable for planting in Dongting Lake area,we conducted an screening test of 22 summer sowing varieties in 2016,with Lin'ao 1 as the first control cultivar,and Zhengdan958 as the second control cultivar. Under the planting density of 5. 25 × 104 plants/hm~2,the yield of the 7 varieties was more than that of the control of the " Lin Ao 1" and " Zhengdan 958". Among them,the yield of Denghai 605,Kangnong669 and NK718 was higher,the comprehensive characters were good,and the growth period was relatively shorter,which did not affect the planting of rape seed. The results show that Denghai 605,Kangnong 669 and NK718 are suitable for the conversion of cotton areas from winter rape-cotton model to winter rape-summer maize model.
