摘要
鄂北岗地近20年来夏玉米生产快速发展,成为湖北省夏玉米新兴最大产区,2015年夏玉米面积11.159万hm2,总产61.4万t,单产366.9 kg/667 m2,比2005年面积扩大1.4倍,总产增1.2倍,单产减9.2%;比1955年面积扩大15.6倍,总产增11倍,单产减41.1%。探索分析了制约该地区夏玉米单产不高不稳,年限间差异较大的主要因素。提出了促进该地区夏玉米生产实现高产稳产快速发展的对策建议。
Through 20 years of rapid develoment,the northern down land of Hubei has newly become the biggest producing area of summer corn. The total yield and per unit yield of summer corn in 2015 were 111.59 thousand hm2,614 thousand tons and 366.9 kg / 667 m2,respectively, which were 1.4,1.2 and-9.2% times larger than their counterparts in 2005 and15.6,11 and-41.1% times than their counterparts in 1955. The main reason that restricted the per unit yield and the large difference between years of summer corn production in this area was analyzed. Strategies were proposed to promote the rapid and steady development of summer corn production in this area.
