洋芋(马铃薯)是我区主要粮食作物之一。每年三季洋芋种植面积一百万亩,占粮食播种面积的八分之一,产量仅次于水稻、包谷而居第三位。由于洋芋生育期短、适应性广、抗灾力强、增产潜力大,所以,无论山区坝区,水田旱地、夏粮秋粮都有种植。有些山区和高寒山区社队,洋芋占粮食总产量的一半以上,有“洋芋半年粮”之说。 Potato (potato) is one of the main food crops in our region. Three quarters of potato planting area of ​​one million mu, accounting for one-eighth of the sown area of ​​grain, yield second only to rice, Valley third place. Due to the short growth period of potato, wide adaptability, strong resilience and high yield potential, so no matter in mountainous areas, dry paddy fields, summer grain crops are planted. In some mountainous and alpine mountain communities, potato accounts for more than half of the total grain output, with “potato half a year”.
