摘要: 为确定河套灌区玉米高产栽培技术措施,挖掘更大增产潜力,于2018年在河套灌区进行了一穴双株不同穴距、行距配置的随机区组试验。结果表明:河套灌区玉米一穴双株栽培,在使用登海618品种,密度9.6万株/hm2,膜上行距40cm条件下,穴距×膜间行距最佳配置为33cm×86cm,36cm×76cm。在对生育时期单株叶面积和干物质变化调查分析表明,36cm×76cm,33cm×86cm穴距、行距配置处理单株叶面积较大且绿叶持续期长,吐丝后干物质积累速度快,36cm×76cm与33cm×86cm产量差异不显著,但36cm×76cm,33cm×86cm与39cm×67cm差异显著,与30cm×96cm,27cm×114cm差异极显著。确定河套灌区玉米一穴双株高产栽培穴距、行距配置为33cm×86cm,36cm×76cm。

Abstract: In order to determine the technical measures for high-yield maize cultivation in Hetao irrigation area and explore greater potential for yield increases,a randomized block group experiment was conducted in 2018 with one hole and two plants using different hole spacings and row spacings.The results show that the optimum allocation of hole spacing×row spacing between films is between 33×86 and 36×76 under the experiment conditions of Denghai 618,96 000 plants/hm2 and 40 cm row spacing on-film.Investigation and analysis of the changes of leaf area and dry matter during the growth period show that 36×76 and 33×86 treatments have larger leaf area per plant,longer green leaf duration and faster accumulation of dry matter after spinning.The yield difference between 36 cm×76 cm and 33 cm×86 cm is not significant,but the differences between 36 cm×76 cm,33 cm×86 cm and 39 cm×67 cm are significant,and the difference between 30 cm×96 cm and 27 cm×114 cm is extremely significant.In conclusion,the optimal hole spacing and row spacing of maize with two plants in one hole with high yield were determined to be 33 cm×86 cm and 36 cm×76 cm in Hetao irrigation area.
