我国西南的高寒山区是苦荞麦的故乡,也是世界苦荞麦的集中产区,常年播种面积在2000万亩以上.数千年来,苦荞麦对我国西南山区的繁荣昌盛起到了不可忽视的作用.苦荞属蓼科荞麦属,我国资源极为丰富,有几百个栽培品种和很多野生类型.苦养生长期短(90～120天),适应性强,耐寒、耐瘠.总状花序,花期很长,占整个生长期的2/3.为自花受粉作物,植株开花数多(达800～1500朵),但结实率极低,只有15～30%,亩产一般只有50～100公斤.近年来,通过改进栽培管理措施和推广良种,大面积示范田的亩产已达200公斤,展示了苦荞生产的巨大潜力.苦荞营养丰富,而且能治多种疾病,是一种很
The alpine mountainous area in southwest China is the hometown of Tartary Buckwheat and is also the concentrated production area of Tartary Buckwheat in the world. The annual planting area is more than 20 million mu. For thousands of years, Tartary Buckwheat has played an important role in the prosperity of southwest mountainous areas in China. The buckwheat is a genus of buckwheat in the genus Polygonaceae. The resources in our country are extremely abundant. There are hundreds of cultivars and many wild types. The period of bitter growth is short (90-120 days), the adaptability is strong, and it is cold-tolerant and rot-resistant. The raceme is very flowery. Long, accounting for 2/3 of the whole growing season. For self-pollinated crops, the number of plant flowering (up to 800 to 1500), but the seed setting rate is very low, only 15 to 30%, mu production is generally only 50 to 100 kg. In recent years, through the improvement of cultivation management measures and the promotion of improved varieties, the per unit area of the large-scale demonstration field has reached 200 kilograms, demonstrating the great potential of bitter buckwheat production. The bitter buckwheat is rich in nutrients and can cure a variety of diseases.
