许多植物的特性及生育进程取决于其发育时期,故需对不同时期进行清楚的描述。除了科学上的用途外,这种法则也适用于玉米大田种植者,因为有关种植措施的决策常常与作物的发育时期有关。本研究旨在提出一种用于西欧条件下玉米物候学的详尽时期描述及十进制法则。本文综合了Hanway(1979)和Schtitte等(1981)的发 The characteristics of many plants and the process of their fertility depend on their developmental period, so they need to be clearly described in different periods. In addition to scientific uses, this rule also applies to cornfield growers, as decisions about planting practices are often related to crop development. The purpose of this study was to present a detailed description of the phenology of the phenology of maize under Western European conditions and the decimal law. This article combines the findings of Hanway (1979) and Schtitte et al. (1981)
