高梁是世界四大作物之一,在我省也是栽培面积较大的粮食作物之一。解放前后,高粱还是我省北部和东部地区群众生活的主食品。七八十年代以后,随着人民生活水平的提高,尤其随着小麦、玉米产量的不断提高,高梁的种植面积逐渐减少。1986年以来,我省高粱常年种植面积仅为300万亩左右,约占粮食作物面积的2—3％。 我省高粱的单产,解放初期不超过100公斤,后来由于生产条件和种植制度的改变,产量有逐年上升的趋势,但到1990年前后,亩产也不过250公斤左
Sorghum is one of the four major crops in the world and is also one of the larger crop cultivars in our province. Before and after the liberation, sorghum was also the staple food of people’s life in the northern and eastern parts of our province. After the seventies and eighties, with the improvement of people’s living standards, especially with the continuous increase of wheat and corn production, the planted area of sorghum has been gradually reduced. Since 1986, the annual planting area of sorghum in our province has been only about 3 million mu, accounting for about 2-3% of the area of food crops. Yield of sorghum in our province did not exceed 100 kg during the early liberation period. Later, due to the change of production conditions and planting system, the yield has been increasing year by year. However, by the year 1990, the yield per mu was about 250 kg
