影响油橄榄产量与品质的气象因子分析

Climate Factors Affecting the Yield and Quality Formation of Olea europaea L.

应用逐步回归分析的方法，研究了贝拉、佛奥、卡林3个油橄榄品种在四川主要种植点产量、含油率与日照、温度、湿度、降雨等23个气象因子的关系．结果表明：光、温、水指标综合影响油橄榄的产量和品质，影响油橄榄产量的气象因子分别为：年日照时数、日照百分率、4～10月日照时数、一月平均温度、极端最高温、极端最低温、O～10℃天数、日稳定通过10℃天数、无霜期天数、4～10月降雨量等．其中4～10月的日照时数是影响油橄榄出油率的关键因子．

Using a method of stepwise regression analysis, this paper conducted a study of the relationship between the olive yield and oil content percentage, of such three olive varieties as Berat, Frantoio and Kaliniot in Sichuan Province, and the 23 climate factors such as sunlight, temperature, humidity, rainfall, etc. Results show that the indexes of light, temperature and water synthetically affect the formation of olive yield and quality. The factors influencing the formation of olive yield are： annual sunlight time, percentage of sunlight, sunlight time from April to October, average temperature of January, extremely high temperature, extremely low temperature, days of temperature from 0 ℃ to 10℃, days of stable temperature above 10℃, non-frost days, rainfall from April to October and so on. Sunlight time from April to October is the key factor which influences their oil formation.
