本文是作者对冬小麦分蘖规律进行五年研究所作总结。文中就试验所获大量数据,运用数理统计方法,重点分析了单株基数(y)与积温(∑T)、肥水条件(d)、种植密度(C)之间的关系,以及不同类型品种间分蘖力(p)差异等。最终求得一个反映小麦分蘖规律的经验公式:lg(?)=0.00166∑T+0.189d-0.44lgc+Lgp+0.105。经反复验证后初步认为:该公式可应用于小麦栽培,对于合理密植和苗期管理等方面都有一定指导意义。
This article is the author’s summary of the five-year study on tillering law of winter wheat. In this paper, a large number of data obtained from the experiment, the use of mathematical statistics method, focusing on the analysis of the relationship between plant base (y) and accumulated temperature (ΣT), fertilizer and water conditions (d), planting density (C) Tillering (p) differences and so on. Finally, an empirical formula reflecting the law of tillering of wheat is obtained: lg (?) = 0.00166ΣT + 0.189d-0.44lgc + Lgp + 0.105. After repeated verification, it is preliminarily thought that this formula can be applied to wheat cultivation and has some guiding significance for the aspects of rational close planting and seedling management.
