一、武汉的气候特点与“两淡”武汉市地处长江中游,年平均温度达16.3—17℃,但冬季寒冷有冰冻,特别是春季、气候多变,多寒潮、大风、连阴雨,影响越冬和早春播种蔬菜生长、推延,使1—5月蔬菜上市供应不足,形成春淡。而夏季的持续高温,或多雨少日照,或雷雨、曝晒等灾害性天气,使舂、夏蔬菜的生长受阻,又形成8—10月的秋淡。这种气候给武汉的蔬菜生产带来困难,实践证明,发展大棚蔬菜生产是抗灾保淡增加供给的一个有效措施。
First, Wuhan’s climate characteristics and “two light” Wuhan City is located in the middle reaches of the Yangtze River, the annual average temperature of 16.3-17 ℃, but the winter cold and frozen, especially in spring, the climate is changing, more cold, windy, and even cloudy, affecting winter And early spring planting vegetable growth, delayed, so that the market supply of vegetables from January to May lack of spring and pale. The continuous high temperatures in summer, or less rainy sunshine, or thunderstorms, exposure and other disastrous weather, so that the growth of summer, summer vegetables blocked, but also the formation of autumn october-October. This climate has brought difficulties to vegetable production in Wuhan. Practice has proved that the development of greenhouse vegetable production is an effective measure to increase the supply of natural disasters.
