不同玉米品种在攀西地区的适应性研究

The Adaptability of Different Varieties of Corn in the Region in PanXi

实验通过登海605、正红311、成单30等15个不同玉米品种在盐源的栽培,在生育时期方面,川单418、凉单4号、登海605较早熟。性状和产量对比上,神珠7号、登海605、川单418、先玉508均在15 000 kg/hm2以上,适应性好,可以在攀西地区进一步实验示范推广;对于产量达13 500 kg/hm2以上的品种成单30、正红311、临奥9号、民玉米1号可以进一步实验。除中单9409和京单28两品种外,其余所有品种产量均超过对照凉单4号。

The experiment is about the cultivation of 15 varieties of corns such as Denghai 605,Zhenghong 311,Chengdan 30 in Yanyuan County.On growth period,some corn varieties are precocious,such as Chuandan 418,Liangdan 4,Denghai 605.About Characteres and yields,some varieties＇ yield are above 15000kg/ hm2,such as Shenzhu7,Denghai 605,Chuandan 418,Xianyu 508,and they are adaptability to palnt in the panxi area.It need further experiment on producing to the species above 13500kg/hm2,such as Chengdan 30,Zhenghong 311,Lino 9,Minyu 1.All corn varieties＇ yield are higher than Liangdan 4 without Zhongdan 9409 and Jindan 28.
