棉花光合作用制造了占?重90%以上的有机物质,而碳素营养又几乎占了其中的一半;所以,同化作用的强弱,制造有机养料的多少,是左右棉花产量的主导因素.但据近年来的研究结果认为:获取棉花高额产量,不仅依赖于棉株同化产物的多少,尤其取决于它的合理运转与分配.据此,我们于1960-1962年,用放射性C~(14)研究了光合产 Cotton photosynthesis makes up more than 90% of the total weight of organic matter, and carbon nutrition accounted for almost half of them; so the strength of assimilation, the production of organic nutrients, is the leading factor in cotton output. According to the findings of recent years, it is believed that the acquisition of high yield of cotton not only depends on the assimilation products of cotton plants, but also on the rational operation and distribution of cotton plants. From 1960 to 1962, we used radioactive C14 ) Studied photosynthesis
