二、光能利用和光合产量太阳光能是棉花生产一切有机物质的能量来源。棉花通过绿色器官的光合作用,将光能转变为化学能贮存于有机物质之中。改善棉田光照条件,提高光能利用率和光合作用效率,是增加棉花产量、改善棉花品质的一项基本技术因素。为了探讨棉花丰产栽培的技术途径,这里介绍几种研究光能利用和光合作用的、比较简便易行的测定方法。光能利用率测定光能利用率的意义光能利用率是指在一定土地面积上的太阳光能被棉花所利用的百分率。研究不同的栽培技术和光能利
Second, the use of light energy and photosynthetic yield Solar energy is the energy source of all organic matter produced by cotton. Cotton through the photosynthesis of green organs, the light energy into chemical energy stored in organic matter. Improving the light conditions of the cotton field, improving the utilization of light energy and photosynthesis efficiency is a basic technical factor for increasing cotton yield and improving cotton quality. In order to explore the technical ways of cotton high-yield cultivation, here are several methods to study light energy utilization and photosynthesis, relatively simple and easy to measure. The utilization of light energy The significance of the utilization of light energy The utilization of light energy refers to the percentage of sunlight that can be utilized by cotton on a certain area of land. Study different cultivation techniques and light energy
