洋芋是我省主要粮食作物之一,具有适应性广,增产潜力大,生育期要求不严,抗灾能力强,营养丰富,用途广的特点。我省中部十八个干旱县历年播种面积在二百万亩以上,约占全省播种面积的一半。多年实践证明,它是这一地区比较抗旱,产量高而稳的粮食作物。合作化后的1956年,十八个干旱县的洋芋平均亩产达到286斤(折主粮,下同),先后有会宁、临洮、永登、庄浪等县亩产超过300斤;景泰、古浪、环县洋芋一年超《纲要》;有的丰
Potato is one of the main food crops in our province, with wide adaptability, large production potential, lagging growth requirements, strong resilience, rich nutrition, wide range of uses. Eighteen drought counties in the central part of the province have a sown area of more than 2 million mu over the years, accounting for about half of the sown area in the province. Years of practice have proved that it is a relatively drought-resistant and high-yielding and stable food crop in this area. After the cooperation, in 1956, the average yield of potato in 18 dry counties reached 286 kg (including the main grain, the same below), and successively more than 300 jin per mu was produced in Huining, Linli, Yongdeng and Zhuanglang.
