二、高海拔温凉稻作区本区主要包括滇中地带,海拔1800～2000米左右水稻地区,一些地点热量和光照等见表2。本区温度年较差小、日较差大,水稻生长期雨水多,云量多,气候温凉,水稻生长前期、后期都易受低温影响而引起烂秧、咆

Second, high-altitude cool paddy area This area includes the central Yunnan area, about 1800 to 2000 meters above sea level in rice areas, some locations such as heat and light in Table 2. In this area, the temperature difference is small, the date is poor, the rice growing season has more rain clouds, more cloud cover, the climate is cool, the early and late rice growth are susceptible to the effects of low temperature, resulting in rotten seedlings and roar
