摘要/Abstract

摘要： 在冬半年(9~2月),对广西南宁市郊杧果园内及空旷地主要气象要素进行对比观测,结果表明,①果园内日平均光照强度为7390 lx,比空旷地(13830 lx)减少46.6%。②果园内日平均气温为21.3℃,比空旷地(21.5℃)低0.2℃;气温日较差比空旷地低0.1℃。③果园内土壤浅层(0~20cm)日均温为20.4~21.1℃,比空旷地(23.3~24.4℃)低1.8~2.8℃;果园内土温日较差为0.5~6.8℃,比空旷地(1.3~12.8℃)低0.8~6.0℃。④果园内日均相对湿度为77%,比空旷地(74%)高3%。⑤果园内日均风速为0.26m/s,比空旷地(1.25m/s)低79.2%。观测数据表明,杧果园内光照强度减弱、温度日较差降低、相对湿度升高、风速减少的效果极为显著。

Abstract: A comparison of meteorological factors was made between mango (Mangifera indica) orchard and open area in winter half year (from September to the next February) in Nanning, Guangxi Province. The results showed that the daily mean intensity of illumination in mango orchard was 7 390 lx, 53.4% lower than that in open area (13 830 lx). Daily mean air temperature (21.3℃) and daily range were lower by 0.2℃ and 0.1℃, respectively, as compared to that in open area. Daily mean temperature of solum (0~20cm) and daily range in soil temperature were 20.4~21.1℃ and 0.5~6.8℃, respectively, 1.8~2.8℃ and 0.8~6.0℃ lower than those in open area, respectively. Daily mean relative humidity of mango orchard was 77%, 3% higher than that in open area, and daily mean wind speed was 0.26m/s, 79.2% lower than that in open area.
