通过对广西永福县小气候条件与罗汉果生长所需的气象条件进行对比分析，结果表明，永福县作为罗汉果传统的生产种植基地，当地光照、温度和水分等气象条件基本适宜罗汉果的生长，其中光照条件较好；3—6月出苗至藤蔓抽生期间温度条件基本适宜，但3月平均温度偏低，各月平均最低温度偏低，易造成寒害；7—9月开花与果实膨大充实期平均温度及积温条件较好，但各月平均最高温度偏高，9月份最低温度偏低，均不利于植株生殖生长；5—7月降水最过大，遇到大雨或暴雨易造成罗汉果落花、落果或根部浸淹现象。针对不利气象条件，提出了可行性的小气候调控建议。%The contrastive analysis between microclimate in Yongfu County of Guangxi and Siraitia grosvenorii’s growth climatic condition was proceeded, the results showed that as a traditional planting base of S. grosvenori, Yongfu County’s climatic conditions such as light, temperature and moisture were suitable for growth of S. grosvenorii, and the light condition was better. The tem-perature was basically suitable for S. grosvenorii’s growth during emergence to vines stage (from March to June), but in March the average temperature was low and mean minimum temperature was low from March to June, which was easy to cause cold injury. The average tempera-ture and accumulated temperature were good during flowering to fruit expanding period (from July to September), but in September the minimum temperature was low and mean maximum temperature was high from July to September, which was not conducive to reproductive growth of S. grosvenorii. The precipitation was high from May to September, the heavy rain was easy to cause flower and fruit drop or roots inundated phenomenon. The fea-sible suggestions of microclimate regula-tion were put forward to deal with the climatic conditions unconducive to S. grosvenorii’s growth.
