测量棉花叶面积,是一项工作量较大而又难度较高的工作,探索简易而正确的测量方法,能大大促进棉花看苗诊断的研究。特别在1979年全国刚统一棉叶测量方法的情况下,迅速研究此项课题,提供简便易行的计算方法,并对以往的老测量方法与现行的新测量方法提出修正数据,更有其现实意义。为此,我们于1979年进行了棉叶面积与长、宽相关关系的研究。 Measurement of cotton leaf area is a heavy workload and difficult work to explore simple and correct measurement methods can greatly promote the research of cotton seedling diagnosis. Especially in the case of the just unified method of cotton leaf measurement in 1979, this subject was promptly studied to provide an easy-to-use calculation method and to propose correction data for old and new measurement methods in the past, more realistic significance. To this end, we conducted a study on the correlation between the area of ​​cotton leaves and the length and width in 1979.
