海拉尔地处内蒙古自治区东部区的北部,大兴安岭的西麓。地理条件是高纬度、高海拔。气候特点是光照充足,但是冬季严寒慢长,夏季温凉短促,春季干旱多风,秋季降温急骤,霜冻早,无霜期仅100天,积温1500℃左右。这种不利的地理和气候条件造成了露地栽培的番茄单产低,上市晚,供应时间短。塑料大棚栽培番茄虽比露地栽培提前一个月(约在7月中旬)上市,但单产仍徘徊在3500公斤左右,收获期也比较集中,满足不了市场的需要。为了继续创高
Hailar is located in the northern part of the eastern region of Inner Mongolia Autonomous Region, the western foot of the Greater Khingan Range. Geographical conditions are high latitudes and high altitudes. The climate is characterized by abundant light, but the winter is cold and long, short in summer and cool in summer, windy in spring, cool in autumn, frost is early, the frost-free period is only 100 days, and the accumulated temperature is about 1500 ℃. This unfavorable geographical and climatic conditions have resulted in low yields of open-field tomato production, late availability and short supply times. Plastic greenhouse cultivation Although cultivated more than a month in the open field (about mid-July) market, but the yield is still hovering around 3500 kg, the harvest is also more concentrated to meet the needs of the market. In order to continue to hit a high
