摘要
对广西南宁市郊芒果园内及其附近空旷地的气象要素进行对比观测。结果表明:①芒果园内的日平均光照度为7 528 lx,占空旷地的28.66％;②果园内日平均气温及日较差依次为23.5℃和5.6℃,相应比空旷地的低0.6℃和0.3℃;③果园内土壤浅层(0-20 cm)日平均温度为22.0-23.5℃,比空旷地的低2.0-3.6℃;④果园内日平均相对湿度为80％,比空旷地的高5％;⑤果园内日均风速为0.16 m/s,占空旷地的14.3％。通过计算机模拟,筛选出果园内外主要气象要素的最佳预测模型。
A comparative study was made on the meteorological factors between the interior orchard of mango (Mangifera indica) and the nearby open area. The results showed that the daily average intensity of illumination in the interior orchard was 7 528 be, 28.66 % of that in the open area. The daily average temperature and daily temperature difference were respectively 23.5 ℃ and 5.6℃ which were 0.6 ℃ and 0.3 ℃ respectively lower than those in the open area. Trie daily average temperatures in the shallow soil (0-20 cm) in the orchard were 22.0 ℃ -23.5 ℃ which were 2.0 ℃ -3.6 ℃ lower than those in the open area. The daily average air relative humidity in the orchard was 80 % which was 5 % higher than that in the open area. The daily average velocity of wind in the orchard was 0.16 m/s, 14.3 % of that in the open area. The climatic environments were simulated with the data available and an optimal predicting model for the meteorological factors in the inside and outside of the orchard was developed.
