摘要： 为了探讨‘衡星401’在江西丘陵旱地种植的生态适应性和可行性，通过对‘衡星401’和江西本地玉米品种‘花花公子彩糯’的产量及植株性状等指标进行对比。结果表明：除了百粒重外‘衡星401’在产量及其构成因素、株高、叶绿素含量、叶片数等方面均优于‘花花公子彩糯’；‘花花公子彩糯’根部干重显著高于‘衡星401’，高出68.61%。由此可以看出，‘衡星401’在江西种植能够取得较高的产量和较好的经济收益，但抗倒伏性较弱，由于江西气候原因，根系差别对其影响不大，因此‘衡星401’适宜在江西丘陵旱地推广种植。

Abstract: In order to explore the ecological adaptability and feasibility of ‘Hengxing 401’ in Jiangxi hilly dryland, this experiment studied the maize yield and plant characteristics by comparing ‘Hengxing 401’ to the local maize variety. The results showed that ‘Hengxing 401’ was better than the local maize variety in maize yield, plant height, content of chlorophyll and blade number in addition to 100-grain weight. Root dry weight for the local maize variety was significantly higher than ‘Hengxing 401’. It could be seen ‘Hengxing 401’ planted in Jiangxi was able to achieve higher yields and better economic benefits, but lodging resistance was weak. Due to the climate the difference of root had little influence on ‘Hengxing 401’. So the cultivation is suitable to promote in Jiangxi hilly dryland.
