宁夏引黄灌区夏栽玉米气候适应性研究

摘要

An study of the climate adaptability of the fresh corn,grain corn and forage maize were carried out in five coun-ties of Ningxia Yellow River Irrigation Area from 2011 to 2012. The results showed that the fresh corn could reach the ed-ible requirement before frosting in autumn. The fresh maize variety NDW68 was suitable for planting in the Ningxia Yellow River Irrigation Area and it can meet the market demand of fresh corn effectively in the late autumn season and the eco-nomic benefits were obvious. The grain maize variety F10-3, Jinggu No. 9 had a big variation in the yield without a stable economic income in different area; in the overall performance, the F10-3 had a better adaptability than Jinggu No. 9. The maturity of forage maize variety ND4, Yinyu series could up to 40% to 60% in the economic harvesting time,and they had a better yield and adaptability as a commercial variety.%2011—2012年在宁夏灌区5个县（区）对鲜食玉米、籽粒玉米、饲草玉米品种进行气候适应性研究。结果表明：在秋季霜冻来临之前，鲜食玉米达到可食收获期，其中鲜食玉米NDW68品种适合在宁夏引黄灌区种植，并在晚秋季节有效补充了鲜食玉米市场供应需求，经济效益明显；籽粒玉米品种F10-3、金谷9号在不同区域内经济收益不稳定，产量变幅较大，总体表现F10-3适应性优于金谷9号；饲草玉米ND4、银玉系列经济收获时成熟度可达4～6成，收益较好，适应性看好，可作为推广品种。
