摘要: 河南省黄淮平原冬小麦分蘖消长的一般规律是:“两个盛期,一个高峰,越冬不停,集中死亡”.用白天平均温度积温(∑Tid)作生物学时间,代替自然天文时间,通过对本区冬小麦分蘖动态与气候生态关系的研究,黄淮平原冬小麦分蘖成穗随气温、土壤湿度等气候生态环境而变化的规律是:(1)最高群体以前:f=ym/(1+ea-b∑Tid·fs·fa-fm (∑Tid<tg)(2)最高群体以后:f=(ym-(ym/(1+e-(a-b∑tid)-1))·fS·fM-fm (∑Tid≥tg)

关键词: 小麦, 群体动态变化, 白天平均温度, 积温, 生物学时间, 动态模拟

Abstract: The present paper is a study on the regularities of the dynamic changes in the tillering and spike-forming of winter wheat and the quantitative relationship between these regularities and the ecoclimatic conditions in Huanghuai Plain of Henan province,based on a lot of field experiments carried out on various sites in that region, The main research result shows hat the changes in the tillering and spiKe-forming of the winter wheat in that region have a close relationship with the ecoclimatic factors such as hemperature and soil moisture, Their quantitative relationships are as follows:(1)Before the maximum plant population:f=ym/(1+ea-b∑Tid·fs·fa-fm (∑Tid<tg)(1)After the maximum plant population:f=(ym-(ym/(1+e-(a-b∑tid)-1))·fS·fM-fm (∑Tid≥tg)

Key words: Wheat, Dynamic changes of plant colony, Mean temperature of daytime, Accumulated temperature, Biological time, Dynamic simulation
