农作物的经济产量和生物学产量,有90—95％是光合作用的产物。因此,研究大田作物光合作用的生产能力,对于制订合理的技术措施,获得优质高产具有重要的意义。原理作物产量是光合器官工作的结果,产量高低主要决定于光合生产率。光合生产率的高低可以从干物质累积的速度测知。通常以每平方米叶面积一昼夜中积累干物质的克数(g/M2/1昼夜)来表示。因此测定某一个时期的叶面积及其在相应时期内增加的干物
Crop economic output and biological yield, 90-95% is the product of photosynthesis. Therefore, to study the crop photosynthesis production capacity, for the development of reasonable technical measures, access to high quality and yield is of great significance. The principle of crop yield is the result of photosynthetic organ work, the level of yield mainly depends on the photosynthetic productivity. The level of photosynthetic productivity can be measured from the rate of dry matter accumulation. Usually expressed as grams of accumulated dry matter per day and night per square meter of leaf area (g / M2 / 1 day and night). Therefore, the leaf area of a certain period and its increase in the corresponding period of dry matter
