内蒙古自治区通辽市主要农业区≥10℃积温为2 800~3 200℃,无霜期90~150天,可满足喜温作物和部分喜热作物的热量要求。由于种植业结构不合理,造成玉米种植效益降低,为优化结构,根据多年试验结果和近年来种植专业合作社大面积示范情况,平原灌区适合洋葱与食用向日葵的套种。该模式一般亩产洋葱4 000 kg,亩产食用向日葵200 kg,合计亩产值5 600~6 400元,亩纯收入2 100~2 900
Tongliao City, Inner Mongolia Autonomous Region main agricultural area ≥ 10 ℃ accumulated temperature of 2 800 ~ 3 200 ℃, frost-free period of 90 to 150 days, to meet the thermophilic crops and some hot crops, calorific requirements. Due to the irrational planting structure, the efficiency of corn planting is reduced. In order to optimize the structure, according to the results of many years of experiments and large-scale demonstration of planting cooperatives in recent years, the irrigated area is suitable for the interplanting of onions and sunflowers. This model generally produces 4,000 kg of onion per mu and 200 kg of sunflower per mu for production, with a total output value of 5,600 yuan to 6,400 yuan per mu and net income of 2,100 to 2,900 yuan
