龙眼产量与关键发育期气象条件关系试验初探

Preliminary experiment for the relationship of longan yield and meteorological condition during its key growth period

对2003～2007年玉林市主栽的石硖龙眼分两个区进行主要发育期观测,同时进行气象要素平行观测,结合近五年龙眼产量的丰歉与关键发育期气象条件的关系进行分析,得出影响其产量的主要气象因素是开花、结果期间遇阴雨寡照,其次为花芽分化期、花穗生长期的天气。

Shixia longan, the main variety in Yuling City, was observed during its key growth period in two plots from 2003 to 2007; Meanwhile, meteorological facts also were accordingly observed. According to the relationship analysis between yield and weather conditions in key growth period in the past five years, the main meteorological factors impacting longan＇s yield would be overcast and rainy weather during blossom and fruit-bearing periods and then the weather in flower bud differentiation period and spike growth period.
