安阳市地处豫北,小麦常年种植面积28万hm2左右。建国60年来,小麦生产发生了巨大的变化,建国初期单产645kg/hm2左右,2008年达到6075kg/hm2,增长9.4倍。60年间,我市小麦经历了10次大范围的品种更换,平均每6年更换一次。由于品种的优良性状不断得到改进提高,配合以栽培条件的改善,每次更换都使小麦单产递增10%左右。

In the early days after the founding of the People’s Republic of China, the yield per unit area was about 645kg / hm2. In 2008, it reached 6075kg / hm2, an increase of 9.4 times. In 60 years, wheat in our city has undergone 10 large-scale variety changes, with an average of every 6 years.
