我们于1973年和1974年对广陆矮4号早稻品种进行了一些栽培和高产试验,在试验进行中作了一些与高产形成密切相关的长势长相方面的观察和分析,主要从茎蘖消长、叶色、叶面积等动态,找出其数量化的预示指标和应采取的促控措施,以供生产上参考运用。现以试验队1.41亩三结合高产试验田形成亩产1,097斤的有关资料为主,结合栽培试验和其它亩产千斤以上田块的调查与体会,进行初步探讨如下。
In 1973 and 1974, we conducted some cultivation and high-yield experiments on Guanglu 4 short-heading rice varieties. During the experiment, we made some observations and analyzes on the long-growing aspects that are closely related to high-yield formation. Leaf color, leaf area and other dynamic, to find out its quantitative indicators and should be taken to promote the control measures for the production of reference. Now the test team 1.41 acres of three high-yielding experimental field formation of 1,097 pounds per mu yield-based information, combined with cultivation experiments and other acres of more than a thousand pounds of field investigation and experience, the initial discussion is as follows.
