春小麦的产量是在植株整体发育的基础上形成的。产量器官(穗)和产量构成因素(穗数、粒数、粒重)有其自身的发生和发展规律,它不仅受种性和外界条件(包括栽培技术措施)的影响,也受植株其它各器官生长发育的影响和体内各生理过程的制约。观察表明,在一定生态条件下春小麦植株各器官之间存在着相互联系的密切依存关系,在完成生命周期过程中,这种关系的协调发展,最终对产量发生决定性影响。为了进一步探讨小麦高产的内在规律,我们在多年对黑卡品种的分蘖消长、幼穗分化和籽粒发育等生育规律,
Spring wheat yield is based on the overall development of the plant. Yield organ (ear) and yield components (number of spikes, grain number, grain weight) have their own occurrence and development of the law, it is not only affected by species and external conditions (including cultivation techniques and measures), but also by the other Organ growth and development and the impact of various physiological processes in the body. The observation shows that under certain ecological conditions, there exists interdependence among all the organs of spring wheat plants. During the completion of the life cycle, the coordinated development of this relationship will ultimately have a decisive influence on the yield. In order to further explore the inherent law of high-yield wheat, we have many years of black card varieties of tiller growth, spike differentiation and grain development and other reproductive rules,
