玉米新品种浚单509生态适应性分析

The Ecological Adaptability Analysis of A New Maize Variety Xundan 509

利用玉米(Zea mays L.)新品种浚单509在湖北省区域试验及大面积示范的数据,对浚单509在湖北省主要玉米种植区的生育期、抗逆性、丰产性等进行了分析。结果表明,浚单509的生育期能较好地适应湖北省的光热条件,具有较好的抗逆性、丰产性和稳产性,特别是丰产性较为突出,适宜在湖北省水肥条件较好的地区种植。

With the data of region experiment and large area demonstration in Hubei province on a new corn cultivar named after Xundan 509, the growth period, stress resistance, yielding ability of Xundan 509 planted in Hubei province,a main maize-production area, were analyzed. The results indicated that： in one hand, the mature stage of Xundan 509 can better adapt to the Solar-thermal conditions in Hubei province. In another hand, the high yield can be made easily because of the good resistance and stability, especially the significant productivity. As a result, the variety was suitable for planting in some regions of Hubei province where the water and fertility conditions are superior.
