通过多年、多种小区高产栽培试验,研究了栽培条件对小麦生育期的影响。结果表明,不同播期、冬性强弱不同品种、不同栽培方法、氮肥运筹时间、施肥种类与配比等栽培条件,对小麦生育期均有显著影响。因此,只有准确掌握不同栽培条件下的小麦生育期,并根据群体大小,麦苗长势、长相和发展趋势,采取相应技术措施,使不同生育期的群体指标合理,才能协调好穗、粒、重三者之间的关系,取得高产。 Through many years, a variety of plot high-yielding cultivation experiments to study the cultivation conditions on the growth of wheat. The results showed that different sowing dates, strong and weak winter varieties, different cultivation methods, nitrogen application time, fertilization types and the ratio of other cultivation conditions had a significant impact on the growth period of wheat. Therefore, only by accurately grasping the growth period of wheat under different cultivation conditions and adopting the corresponding technical measures according to the population size, the growth of wheat seedlings, the appearance and the development trend, the population indicators at different growth stages are reasonable to coordinate the spike, grain, The relationship between the high yield achieved.
