关于小麦单株分蘖规律的理论,日本片山佃1944—1951年对稻麦主茎叶片和分蘖同伸关系做过比较系统研究。后人根据小麦分蘖模式图,推断出主茎叶龄与各次分蘖叶龄的关系及主茎某叶龄(n)的总分蘖值为前两个叶龄(n-1和 n-2)的总分蘖值之和(包括主茎)。这些都在一定程度上表达了小麦单株分蘖的特征。应用数学归纳推理方法,建立数学公式以准确表达小麦理论分蘖值,在理论和实践上更有其应用价值。近来,已有人做了这方面的探讨。为了从理论上探索分蘖规律并说明三叶期前无分蘖问题,本文试图推导并建立下述三个公式用以计算小麦理论分蘖次数,小麦第 i 次分蘖理论值和小麦单株总分蘖理论值。
On the theory of tillering law of wheat plants, Japan’s Dian Dian Dian 1944-1951 years on the main stems of rice and wheat stems and the relationship between tillering done a relatively systematic study. The descendants deduced the relationship between main stem leaf age and each tillering age and the total tillering value of a certain leaf age (n) of the main stem as the first two leaf ages (n-1 and n-2) The sum of total tillers (including the main stem). These are to some extent expressed the characteristics of tillering of individual plants. Applying mathematical inductive inference method and establishing mathematical formula to accurately express wheat theoretical tillering value have more application value in theory and practice. Recently, some people have done this discussion. In order to theoretically explore the tillering rule and explain the tillering problem before the three-leaf stage, this paper attempts to derive and establish the following three formulas to calculate the number of theoretical tillers of wheat, the ith tillering value of wheat and the theoretical value of total tillering of wheat .
