摘要
[目的]为四川省更好地种植油橄榄提供依据。[方法]比较四川省主要油橄榄引种地与原产地地中海的气候条件，分析引种地的气候利弊因子，提出相应的引种建议。[结果]四川省油橄榄引种地年平均气温、1月平均温度与原产地较接近，极端最低温度不会导致冻害发生，适合油橄榄生长。四川引种地夏季降水量为178．3～215．5mm，远远高于原产地的0-30．0mm，利于油橄榄的营养生长。除西昌外，其余引种地年日照时数为1300～1400h，低于原产地的2493～2783h。引种地年均相对湿度的平均值为72．2％，高于原产地的平均值69．0％。[结论]四川省油橄榄引种地的年日照时数不足、空气相对湿度较大限制了油橄榄的生长，可以通过阳坡种植，整形修剪，种植耐湿性较强的油橄榄品种，合理施肥等措施弥补。
[ Objective] The aim of the study was to supply basis for planting Olea european better in Sichuan Province. [ Method] The climatic conditions of main introducing areas of O. european in Sichuan Province and its original producing area Mediterranean were compared, the advantage and disadvantage climatic factors of introducing areas were analyzed and the corresponding introducing suggestions were put forward. [Result] The annual average temperature and January average temperature of introducing areas of O. european in Sichuan Province was closer to that of original producing area and the extremely lowest temperature wouldn＇t induce occurrence of freezing injury, so the area were suitable for O. european growth. The stunner rainfall of Sichuan introducing areas was 178.3 - 215.5 mm and far higher than 0- 30.0 mm of original producing area, which was in favor of the nutritive growth of O. european. Except for Xichang, the annual sunlight hours of the other introducing areas were 1 300- 1 400 h and lower than that of original producing area （2 493 - 2 783 h）. The average value of annual average relative humidity of introducing areas was 72.2% ,being higher than that of original producing area （69.0%）. [Conclusion] The deficiency of annual sunlight hours and bigger relative air humidity of introducing areas in Sichuan Province limited the growth of O. european, which could be compensated through measures of planting on sunny slope, shaping and pruning, planting O. european varieties with stronger humidity-resistance and fertilizing reasonably etc.
