前言大豆的生长发育和产量的形成,在很大程度上取决于同化器官的大小,及其生理功能的强弱。因此,目前在国内外生产上,采取缩垅增行,加大种植密度等,就是通过增加同化作用面积,高提大豆对光能的利用,达到高产的一种措施。但是,在生产上有时庙于密植,特别是高肥足水的情况下,光合作用面积增大的结果,常常引起田间通风透光状况不佳,降低光合作用力,反而减产。这说明在一定的栽培条件下,必须配置以一定的相适应的群体结构,才能有效的利用光能,获得高产。因此,研究如何有效地提高光合作用强度,进行合理的田间布局是十必要的。
Preface The growth of soybean and the formation of yield depend largely on the size of the assimilation organ and its physiological function. Therefore, at present, at home and abroad, adopting measures to increase production and increase planting density is a measure to achieve high output by increasing the area of assimilation and raising the utilization of light energy by soybean. However, when the temple is densely populated in production, especially with high fertility, the photosynthesis area increases often resulting in poor ventilation and light in the field, reducing photosynthesis and reducing production. This shows that under certain cultivation conditions, it must be configured with a certain population structure to adapt to the effective use of light energy to obtain high yield. Therefore, it is necessary to study how to effectively improve the photosynthesis intensity and make reasonable field layout.
