【摘要】 对福建省连江县2004-2005年冬季低温考察资料进行分析,在相对高差为80 m的丘陵山地和相对坡位约0．8的山坡中上部,晴天最低气温常出现最高,逆温效应最明显,故橄榄园地宜选择相对坡位在0．5以上的地段; 对于相对高差小于50 m的丘陵山地,晴天最低气温随高度的增加而增加,越近坡顶,最低气温越高,应尽量选择近坡顶的地段建立橄榄园。在这些地段种植橄榄可减轻或避免低温造成的冻害。更多还原

【Abstract】 The data about extremely low temperature in winter of 2004 in Lianjiang County were analyzed. Extremely low temperature in hillside with 80 meters relative height or in middle and top part with 80% relative slope in sunny day increased, the temperature inversion was evident, so olive garden should be selected at zone above 50% relative slope. In hillside with relative height below 50 meters, extremely low temperature in sunny day increased with the height. The nearer to the top of hillside, the higher value of extremely low temperature was observed , so olive garden should be selected at zone near the top. Planting olive in these zone can reduce or avoid low temperature hurt.更多还原
