玉米的生长发育是通过绿色叶片的光合作用,把无机物转化为有机物,把太阳能转化为化学能的一个物质能量转化过程。在大田生长中,这个能量转化过程是在自然条件下进行的,受气象条件的影响很大,尤其是温度和日照时数是影响玉米生长发育的主要气象因子。玉米产量的高低与灌浆进程中的气瘟和日照时数有密切的关系。下面具体分析温度和日照对 Corn growth and development through the photosynthesis of green leaves, the inorganic matter into organic matter, the solar energy into chemical energy, a material energy conversion process. In the field growth, this energy conversion process is carried out under natural conditions, greatly affected by the weather conditions, especially temperature and sunshine hours are the main weather factors that affect the growth and development of corn. The level of corn yield and grouting in the process of gas blast and sunshine hours are closely related. The following specific analysis of temperature and sunshine
