以玉米品种鄂玉19、正大999、源育16、中科10号、临奥1号为材料,在娄星区双江乡方石村进行了栽培比较试验。结果表明:在高温干旱严重的气候条件下,鄂玉19表现出较强的抗旱性,丰产性能好,适宜湘中地区山丘区种植推广;源育16、正大999、中科10号都表现为抗旱性较弱,7月上旬至8月上旬的高温干旱天气对这3个品种灌浆结实影响较大,导致其后期茎叶干枯,产量较低,适宜在湘中抗旱力较强的平丘区种植。
The cultivars of Cultivars of E 玉 19, Chia Tai 999, Yuanyu 16, Zhongke 10 and Liniao 1 were compared in the Fangcun Village, Shuangjiang Village, Louxing District. The results showed that under high temperature and arid climate, Eyu19 showed strong drought resistance and high yielding performance, which was suitable for the popularization of hillsides in central Hunan. Source Yu 16, Zhengda 999, Zhongke 10 For the drought resistance is weak, high temperature and drought weather in early July to early August on the three varieties of greater impact on grain filling, resulting in the late stems and leaves dry, low yield, suitable for drought in Hunan Pingqiu District Planting.
