科技援疆是国家的一项重大战略决策。为促进新疆玉米科研发展并探索引种经验和高产经验,提高玉米的经济效益,山西玉米所2013年开始进行玉米新品种在当地的引种试验。通过引种山西近年育成的42个玉米品种,采用设置对照,间比排列试验,进行田间精细管理,并调查了各农艺性状等。从试验结果可以看出环境改变和密度增加、覆膜栽培对株高、穗位、生育期产生了影响,大部分品种不能适应新疆气候,但仍有部分品种生育期适中,农艺性状优良,抗性优良,产量超过对照,说明山西育成的部分品种对新疆的气候和栽培模式有较好的适应性,可以筛选利用。因此,笔者认为适宜新疆春播种植的玉米品种应具有高的产量潜力,耐密植栽培,生育期适中,抗倒能力强和适合机械化作业等特性。
Technology Aid Xinjiang is a major national strategic decision. In order to promote the scientific development of maize in Xinjiang and explore the introduction experience and high yielding experience and improve the economic benefits of maize, Shanxi Maize introduced the introduction test of new maize varieties in 2013. Through the introduction of 42 maize varieties bred in recent years in Shanxi Province, we set up the control and inter-ratio test to conduct field fine management and investigated the agronomic traits. From the test results, it can be seen that the environmental changes and the density increase, the filming cultivation has an impact on plant height, ear position and growth period, most of the varieties can not adapt to Xinjiang climate, but some varieties have moderate growth period, good agronomic traits, Excellent quality, yield more than the control, indicating that some cultivars in Shanxi climate and cultivation patterns in Xinjiang have better adaptability, can be screened. Therefore, I believe that suitable for spring planting of maize varieties in Xinjiang should have high yield potential, tolerance to close planting, moderate growth period, anti-down ability and suitable for mechanized operations and other characteristics.
