梅州沙田柚采摘时间研究

Research on Picking Time of Shatian Pomelo in Meizhou

对1995-2006年梅州市26个果场沙田柚可溶性固形物(俗称甜度)平均值与同期相关气象条件进行了相关分析,并进行了滑动T检验,结果表明:柚果甜度主要受其生殖生长后期的雨量、日照、温度日较差3种气象条件影响,UA经过回归分析,定义了沙田柚的"始采日"",始采日"之后,便可以开始采摘柚果。

Shatian pomelo average soluble solids contents from 26 fruit markets In Meizhou city from 1995 to 2006 and related weather conditions were analyzed, and the sliding T-test was used. The results showed that pomelo fruit sweetness mainly effected by the rainfall, sunlight, air temperature weather conditions at the late stage. After regression analysis, Shatian pomelo＂before mining＂ was dif＇~ned. The day was in June, and the cumulative number of sunshine hours in the day of 984 hours, or in September, and the cumulative temperature of 604 ℃, the later date was ＂before mining＂. After ＂before mining＂, Shatian pomelo fruit could be started to pick, in order to guarantee the quality and weight of pomelo fruit.
