玉米的整齐度,指的是玉米群体中个体之间的数量差异。这种差异可以表现在形态上(如株高、穗位高,茎租、叶面积等),也可以表现在生长量上(如干重等)。一个作物群体中,个体之间整齐与否,将会给群体结构带来“数”和“质”的差异。并且差异越大,整齐度就越低;差异越小,整齐度就越高。根据我们1979年、1981年试验 The uniformity of corn refers to the number difference between individuals in a corn population. This difference can be manifested in morphology (such as plant height, ear height, stem rent, leaf area, etc.), can also be expressed in the amount of growth (such as dry weight, etc.). A crop group, the tidy individual or not, will bring to the group structure “number” and “quality” difference. And the greater the difference, the lower the uniformity; the smaller the difference, the higher the uniformity. According to our 1979, 1981 trial
