摘要
高光效那氏大穗玉米在娄烦试点引种成功后,2016年又在山西北部及吕梁的文水等地进行了多点试验,通过在山西北部的阳高、怀仁和原平3个试点,对GPIT那氏大穗玉米与对照先玉335的籽粒和茎秆含糖量、单位面积产量、穗和茎叶的农艺性状进行了比较分析。结果表明,GPIT那氏大穗玉米在高光效的作用下,不仅提高了籽粒和茎秆的品质,而且也大幅提高了产量及抗寒性,同时也表明了该品种广泛的适应性。可为今后其在山西大面积推广种植提供理论依据。
After the big ear maize with high photosynthetic efficiency was introduced success in Loufan, a number of experiments were carried out in northern Shanxi and Wenshui of Ltlliang, and other places in 2016. The grain and stalk sugar content, per unit area yield, panicle, leaf and stem agronomic traits of GPIT＇s big ear maize and Xianyu 335 were analyzed in Huairen, Yuanping and Yanggao of northern Shanxi. The result showed that under high efficiency effeet, GPIT＇s big ear maize not only improved the quality of the grain and stem, but also greatly increased the production and also improved the resistance to cold. At the same time, it showed that the variety had a wide range of adaptability, which will provide a theoretical basis for the promotion of planting in Shanxi in the future.
