大兴安岭地区属于寒温带大陆性气候。冬季长,夏季短。加格达奇以北全年无霜期不足100天,吸中、新林以北全年不足90天局部地区还有终年永冻层。加格达奇年平均气温——-2℃,北部阿木尔——-5.2℃昼夜温差大,具有明显的山地气候特色。由于气候因素的影响,严重的影响茄果类及瓜类蔬菜的发展。塑料棚蔬菜生产的出现给林区蔬菜生产开辟了广阔的前景。经过几年的实践证明:利用塑料棚栽培蔬菜这项新兴的园艺技术突破了高寒地区不能生产瓜类,茄果类蔬菜的禁区,结束了“端午节”前吃不到地 Daxinganling region belongs to the temperate continental climate. Long winter, short summer. North of Jiagedaqi frost-free period throughout the year less than 100 days, suction, the new forest north of the whole year less than 90 days there are permanent permafrost in some areas. Jiagedaqi annual average temperature --- 2 ℃, the northern Amur --- 5.2 ℃ temperature difference between day and night, with obvious mountain climate characteristics. Due to the influence of climatic factors, it seriously affects the development of eggplant and melon vegetables. The emergence of plastic shed vegetable production to forest vegetable production has opened up a broad prospect. After several years of practice has proved that: the use of plastic shed cultivation of vegetables this emerging horticultural technology breakthrough in the alpine region can not produce melons, solanum vegetables forbidden zone, ending the “Dragon Boat Festival” can not eat before
