云南气候、地势复杂,属赤道季风气候,夏季为赤道空气所控制,空气湿度及雨量剧增,湿度相应下降,日夜变幅减小;冬季为热带空气所控制,温度及雨量显著减少,温度日夜变幅加大,四季不清,干湿两季分明。而各地气候因地势差异大,纬度影响小,沿江河流域为热带及亚热带性气候,年平均气温18—24℃,雨量600—1000毫米,一般霜期30—90天,有些地区终年无霜或间有轻霜(表1)。在此条件下,既能生长不同
Yunnan has a complex terrain with equatorial monsoon climate. In summer, it is controlled by the equatorial air. The air humidity and rainfall increase drastically, the humidity decreases correspondingly, and the amplitude of day and night decreases. In winter, it is controlled by tropical air, temperature and rainfall are significantly reduced, and temperature varies day and night Magnitude, four seasons, wet and dry seasons. However, the climatic conditions vary greatly from place to place, with little impact on latitude. The rivers and lakes are tropical and subtropical. The annual average temperature is 18-24 ° C and the rainfall is 600-1000 mm. The frost season is usually 30-90 days. In some areas, frost- A light cream (Table 1). Under this condition, both can grow differently
