光照和温度是粮食生产中重要的自然因素,如何充分利用太阳能,提高作物光合效率,形成更多的籽粒产量;如何使粮食作物获得适温条件以促进生长发育,而免于遭受高、低温的危害,这是粮食生产中急待研究的重要课题。因此,分析光温的自然规律,合理调整茬口和布局,趋利避害,以促进粮食作物持续高产稳产,具有重要的现实意义。一、郊区粮田光能利用的特点作物摄取的能量,绝大部分来自太阳的辐射能。人们的食粮主要依靠绿色叶片的光合活动,从事粮食作物栽培研究工作,无非 Light and temperature are important natural factors in food production. How to make full use of solar energy to improve the photosynthetic efficiency of crops and create more grain yield? How to make food crops suitable for growth to promote growth and development without suffering from high and low temperature Harm, which is an urgent issue in food production research. Therefore, it is of great practical significance to analyze the natural law of light and temperature, adjust stubble layouts and layout rationally, and seek benefits and avoidance so as to promote the sustained and high yield of grain crops. First, the characteristics of light energy utilization of suburban grain fields Crops intake of energy, most of the radiation from the sun. People’s food mainly rely on the photosynthetic activities of green leaves, engaged in food crops cultivation research work, nothing more
