作物产量的形成是由多种因素决定的.但是,所需能量的主要来源是太阳总辐射.小麦干物质的90%以上是靠太阳光能进行光合作用得到的.由此,太阳总辐射量的多少,以及与其相关的实际生育期的长短、大气中二氧化碳含量的高低、昼夜温差的大小等等,构成为影响小麦高产量的主要的气候因素.阜南县位于我国南北农区的交接地带,因此,将上述几个方面的情况与南北两个高产冬麦区(云南省的丽江县和首都北京)进行对比,这对了解阜南的气候特点,进而探讨与之相适应的技术措施,将是有所帮助的. (一)总辐射.总辐射是由太阳的直接辐射和散射辐射组成的.它包含着光能和热能,其中光能是作物产量形成的能源.因此,辐射量大,形成的光合产物就
The formation of crop yields is determined by a number of factors, but the main source of energy required is the total solar radiation, and over 90% of the wheat dry matter is obtained from photosynthesis using solar energy, whereby the total solar radiation , And the related actual growth period, the level of atmospheric carbon dioxide, the temperature difference between day and night and so on, constitute the main climatic factors that affect the high yield of wheat.Fu Nan county is located in the transfer zone Therefore, comparing the above-mentioned aspects with the two high-yielding and winter wheat regions (Lijiang County, Yunnan Province and the capital city of Beijing) in both North and South, it is of great significance to understand the climate characteristics of Funan and to explore the technical measures that are suitable for it. (I) Total Radiation The total radiation consists of the direct and diffuse radiation of the sun, which contains both light and heat, of which light is the energy that forms the crop, so that the amount of radiation , The formation of photosynthetic products
