三年来,我們在总結农业丰产經驗和研究农作物高产生理的工作中,摸索着从生产实践通向理論研究的道路。室內室外都进行了試驗,参加不少調查研究和座談会,接触很多新問题和新事物。在双百方針的鼓舞下也爭論过不少問題,有的較一致了,有的相持不下,尚待更多的試驗去解决。这里就我們在小麦丰产問題研究中的粗浅体会,提出几点加以討論。 前期的生长基础和后期的干物質累积 小麦产量的形成过程可以大体分为两个 In the past three years, we have groped for the path leading from production practice to theoretical research in summing up the experience of agricultural bumper harvests and studying the high-yielding physiology of crops. Both indoor and outdoor have been tested, to participate in many surveys and seminars, exposure to many new issues and new things. Encouraged by the “two hundred principles”, many issues have also been debated. Some have been more consistent with others and some have been stymied for more trials to be resolved. Here are some basic ideas we will make about the research on wheat high yield. The pre-growth basis and the late dry matter accumulation of wheat yield formation can be broadly divided into two
