一、甘蔗的光能利用与栽培农作物的生产,归根到底是光能利用问题。因为在组成农作物的总产量中(干物计),约有90～95％的物质是通过光合作用,依靠太阳能合成的。因此,作物光能利用能力的大小,直接影响到作物的产量,甘蔗也不例外。这里要谈一下光能利用率。所谓光能利用率是指:农作物生产过程中,太阳光的辐射能通过光合作用转化成化学能而贮存于光合
First, the light energy utilization of sugarcane and cultivation of crop production, in the final analysis is the issue of light energy use. Because about 90-95% of the total crop (dry matter) that make up a crop is produced by photosynthesis and solar energy. Therefore, the ability of crop light to use the size of a direct impact on crop yields, sugar cane is no exception. Here to talk about the utilization of light energy. The so-called light energy utilization refers to: the crop production process, the solar radiation through photosynthesis into chemical energy and stored in photosynthesis
