1990～1993年在河北石家庄省粮油作物所进行了杂种小麦生育规律研究。结果表明,杂种小麦具有明显的生长优势及产量优势,表现在营养体旺盛、根系发达、灌浆强度大、粒重高等。用灰色理论的关联度分析方法研究了不同产量水平下各产量因素对产量的影响,提出了不同阶段的主攻方向,并分析了杂种小麦的发育特点在超高产栽培中的应用问题。
From 1990 to 1993 in Shijiazhuang, Hebei Province, grain and oil crops conducted a study of the law of the growth of hybrid wheat. The results showed that the hybrid wheat had obvious growth advantages and yield advantages, manifested in exuberant vegetative body, developed root system, large grouting intensity and high grain weight. The effects of yield factors on yield were studied by the gray relational analysis method. The main directions of different stages were put forward. The application of heterosis in super high yielding cultivation was also analyzed.
