农业生产的主要特点在于它以动植物为生产工具,同时又以动植物产品为生产目的。就作物栽培来说,我们收获的粮、棉、油料等产品,都是农作物在一定栽培条件下,靠它们的代谢机能,以Co_2、水和少量矿質元素为原料,以阳光为动力,经过复杂的过程而制造出来的。在这里起主要作用的是光合,农产品干重的90-95%以上都是来自光合的。许多农业措施的增产作用,归根结底,都是通过促进光合而实现的。反过来说,任何措施,假如不能有利于光合,那末最后必不可能达到增产的目的。由此可见,对于农作物光合性能的研究,在农业生产上具有头等重要的意义。
The main characteristic of agricultural production lies in its use of plants and animals as a production tool, and at the same time its production of animal and plant products. For crop cultivation, the crops, cotton, oilseeds and other products we harvest are all crops under certain cultivation conditions, relying on their metabolic functions, using Co2, water and a small amount of mineral elements as raw materials, using the sun as the driving force, Complicated process and create it. Here is the main role of photosynthesis, agricultural products, more than 90-95% of dry weight comes from photosynthesis. Many agricultural measures to increase production, after all, through the promotion of photosynthesis and achieve. Conversely, any measure, if not conducive to photosynthesis, then the final will not be able to achieve the purpose of increasing production. Thus, the study of crop photosynthetic properties, in agricultural production has the first-class significance.
