为探索豫北地区实现小麦超500kg/667m~2栽培措施,1989～1992年选用“冀5418”和“偃大7916”品种,进行小麦高产栽培试验。经过3年的试验研究获得了小麦超500kg/667m~2的生理指标及其栽培技术。1991年7.1hm~2试验田单产达515.6kg/667m~2,其中0.4hm~2冀5418达640.9kg/667m~2,0.8hm~2偃大7916达578.0kg/667m~2。1992年,该地又实现502.2kg/667m~2的高产。
In order to explore the cultivation of super-500kg / 667m ~ 2 wheat in the north of Henan Province, from 1989 to 1992, “Ji 5418” and “Yan-Tai 7916” were selected for high-yielding cultivation of wheat. After three years of experimental research to obtain wheat over 500kg / 667m ~ 2 physiological indicators and its cultivation techniques. In 1991, the yield per plant of 7.1hm ~ 2 reached 515.6kg / 667m ~ 2, of which 0.4hm ~ 2 Ji 5418 reached 640.9kg / 667m ~ 2,0.8hm ~ 2 Yan 7916 up to 578.0kg / 667m ~ 2. In 1992, To achieve 502.2kg / 667m ~ 2 high yield.
