玉米叶片是玉米的主要冈化器官。要获得高产,必须有一定的叶面积作基础。玉米叶片的形状,同一品种虽然相对稳定,但叶片面积的大小,与其形成时的条件有密切关系。因此,在生产上进一步了解玉米叶片的生长规律及其与肥水的关系十分必要。为此,一九七八到一九八○年连续三年对其进行了测定研究,并得出如下结果。 Corn leaves are the main organs of corn. To obtain high yield, there must be a certain leaf area as the basis. Maize leaf shape, although the same species is relatively stable, but the size of the leaf area, and its formation conditions are closely related. Therefore, in the production of a better understanding of the growth of corn leaves and its relationship with fertilizer and water is necessary. To this end, from 1978 to 1980 for three consecutive years of its determination of the study and draw the following results.
