福州地区地处东南沿海,属海洋性气候。虽年均气温较高,雨量充沛,对蔬菜的周年供应有一定好处,但由于北方冷空气的影响,每年4～5月,气候变化大,阴雨低温天气频繁出现,谓之“倒春寒”。继而又出现阴雨连绵的霉雨季节,对早春蔬菜生产极为不利,是造成福州地区蔬菜供应淡季的主要原因。 Fuzhou area is located in the southeast coast, is a maritime climate. Although the annual average temperature is high and the rainfall is abundant, it has some benefits for the annual supply of vegetables. However, due to the cold air in the north, there is a large change in climate from April to May each year, with frequent occurrence of overcast and cold weather, which means “late spring cold”. Followed by rainy and rainy mildew season, which is extremely unfavorable to vegetable production in early spring and is the main reason for the off-season vegetable supply in Fuzhou.
