甘薯具有高产、耐旱、耐瘠薄、无明显的生育期等特点,荒山坡地、新垦荒土地均可种植,因此被称作最重要的救灾作物。针对四川省此次强地震对耕地造成严重破坏的实际,甘薯可作为灾后恢复生产,解决灾民基本粮食供应的主要作物。 Sweet potato has the characteristics of high yield, drought tolerance, infertility resistance and no obvious growth period. It is called the most important disaster relief crop because it can be planted on barren hillsides and newly reclaimed land. In view of the fact that the strong earthquakes in Sichuan Province caused serious damage to cultivated land, the sweet potato can be used as the main crop for post-disaster recovery and production and for solving the basic food supply for the victims.
