属珠江水系的广西红水河流域,位于北纬22°52′—25°37′、东经106°12′—110°23′之间,地处两个过渡带:一是由云贵高原的东南缘向华南沿海丘陵过渡,二是从中亚热带向南亚热带过渡,为亚热带季风湿润、半湿润气候区。热量丰富,降水较充沛,光、温、水基本配合较好,年平均气温16.8—21.6℃,≥10℃年积温为4978—7843℃,持续期长达252—328d,最冷月(1月)均温7.6—12.3℃,最热月(7月)均温27.4—33.2℃,极端最低气温只有-3.3—-5.5℃;

It belongs to the Pearl River Basin in Guangxi Hongshui River Basin, located between latitude 22 ° 52’-25 ° 37 ’and longitude 106 ° 12’-110 ° 23’, and is located in two transitional zones: one is from the southeastern margin of the Yunnan-Guizhou Plateau The transition to the coastal hills in South China, the second is the transition from the subtropical to the southern subtropics, subtropical humid monsoon climate zone. It has abundant heat, abundant precipitation, good basic temperature, light and water. The annual average temperature is 16.8-21.6 ℃, the accumulated temperature ≥10 ℃ is 4978-7843 ℃, the duration is 252-328d, the coldest month (January ) Average temperature 7.6-12.3 ℃, the hottest month (July) average temperature 27.4-33.2 ℃, the extreme minimum temperature is only -3.3 - 5.5 ℃;
