荞麦是粮食作物中比较理想的填闲补种作物,旧时。许多人把荞麦称为“救灾作物”,在一些遭受旱涝灾害地区的贫困群众常把它当做“救急粮”。这是由于荞麦其有生长期短,不耐霜,适宜在气候寒冷或土壤贫瘠的土地栽培的特点(一般只需60～80天就能成熟收获)。因此,灾民往往抢种荞麦等快熟作物,以糊口度荒。 Buckwheat is an ideal reclaimed crop in food crops, old. Many people refer to buckwheat as a “relief crop,” and are often used as “emergency food” by poor people in areas affected by droughts and floods. This is because buckwheat has a short growth period and is not resistant to frost. It is suitable for cultivation in cold or poor soil conditions (usually only 60 to 80 days to mature and harvest). Therefore, the victims often rush to seize buckwheat and other fast-growing crops, to survive a shortage.
