本文以棉株主茎展开叶数,打顶后以顶部第一果枝展开叶数表示生育进程。研究展叶进程与主茎叶、花芽、果枝和果节数之间的关系;研究展叶进程与生育进程、“三桃”形成、优质、高产构成之间的关系,从而建立生育进程看叶诊断模式,为棉花优质高产栽培提供理论依据。 In this paper, the number of main leaves of cotton plant expansion leaves, after the top to the top of the first fruit branch to expand the number of leaves that the process of fertility. Studying the relationship between the leaf development process and the main stem, flower buds, fruiting branches and fruit nodes; Studying the relationship between the leaf development process and the reproductive process, the formation of “three peaches”, the formation of high quality and high yield, so as to establish the growth process Diagnostic models provide a theoretical basis for high-quality cotton cultivation.
