GPIT那氏大穗玉米在重度盐碱地的种植试验

The Planting Experiment of GPIT Big Ear Corn in Serere Alkali Area

为了进一步验证GPIT那氏大穗玉米的耐盐性,对那氏大穗玉米在重度盐碱地进行了种植试验。结果表明,与对照正大12比较,那氏大穗玉米植株在叶片特征、根系特征上均发生了明显的变化,其茎秆的产量和品质、籽粒产量因子和产量也明显得到了提升,说明那氏大穗玉米在高光效特性的前提下,也使其耐土壤盐碱的能力得到了提高;如果再辅以相应配套的栽培技术,那氏大穗玉米在重度盐碱地上的增产潜力将会得到更加明显的体现。

To further verify with salt resistance of GPIT big ear corn,the planting experiment of big ear corn in severe saline alkali soil was carried out.The results show that compared with Zhengda 12,the leaves,root system characteristics have taken place obvious changes,and also lead to the stem yield and quality,grain yield and yield factor improve significantly,which explains the big ear corn on the premise of high photosynthetic efficiency features,soil salinity resistance ability is also improved.If the technique of cultivation is supplemented by the corresponding technology,the potential of the yield increase on the high salt alkali land will be more evident.
