滇中高原光能资源丰富，不仅表现在太阳辐射量高于我国东部平原丘陵河谷区，而且辐射强度大，是水稻、冬小麦等作物的高产基地。全年热量资源较充足。但温度年较差小，冬暖夏凉，一年四季都能种植小麦，是滇中高原小麦气候生态的一大特点。夏季高温强度不大，水稻冷害突出，以致滇中高原不宜引种我国大部分稻区的水稻品种，应重点培育适应本地区的高产耐寒品种。全年降水量适中，但干季降水量只占全年总降水量的１０％～１５％，湿季为８５％～９０％。干季降水量少是限制冬小麦以及水稻拔节前生长发育的关键因子。发展农田水利和灌溉是夺取滇中高原水稻、冬小麦高产、稳产最重要的措施 The abundant light energy in the Central Yunnan Plateau is not only reflected in the fact that the solar radiation is higher than that in the hilly valley region in the eastern plain of China, but also has a large radiation intensity and is a high-yielding base for crops such as rice and winter wheat. More adequate heat resources throughout the year. However, the annual temperature difference is small, warm in winter and cool in summer and can be planted throughout the year. It is a major feature of the wheat climatic ecology in the Central Yunnan Plateau. High temperature intensity in summer is not prominent, so the chilling damage of rice is prominent, so that it is not appropriate to introduce rice varieties in most of the rice-growing areas in the Central Yunnan Plateau. Therefore, we should focus on cultivating high-yield and cold-tolerant varieties adapted to the region. The precipitation is moderate throughout the year, but the dry season precipitation accounts for only 10% -15% of the total annual rainfall and the wet season is 85% -90%. The small amount of precipitation in dry season is the key factor to restrict the growth and development of winter wheat and rice before jointing. Development of farmland water conservancy and irrigation is the most important measure to seize high yield and stable yield of rice and winter wheat in central Yunnan
