本文根据小麦器官建成的同伸规律与肥水效应等有关研究资料,在进行验证性研究工作的基础上,进一步总结研究了小麦不同叶龄与穗分化进程的对应关系,提出以“叶龄余数”做为鉴定穗分化和同伸器官的生长发育进程的外部形态指标;并在总结研究北京郊区和全国小麦高产规律的基础上,提出了W型和V型两套“叶龄指标促控法”,1975年以来在北京郊区推广,获得了较显著的增产效果,并逐步纳入规范化栽培技术体系。1980年“叶龄指标促控法”被农业部列为全国重点推广项目。
Based on the research data about the law of isotonic growth and fertilizer and water effect built in wheat organs and so on, based on the confirmatory research work, the paper further summarizes the corresponding relationship between different leaf ages and spike differentiation of wheat, As the external morphological index to identify the process of spike differentiation and isomorphic organ growth and development; and on the basis of summarizing the laws of high yield of wheat in the suburbs of Beijing and the whole country, two sets of W-type and V-type “ Since 1975, it has been popularized in the suburbs of Beijing and obtained more significant stimulation effects and gradually incorporated into the standardized cultivation technology system. In 1980, the ”Leaf Age Indicator Control Law" was listed as a national key promotion project by the Ministry of Agriculture.
