甜菜是安达县主要经济作物之一,近年来,种植面积稳定在23万亩,占耕地面积14.6％。然而,甜菜茬种植其它作物产量较低:玉米一般亩产仅300多斤,谷子亩产200斤左右,大豆不足100斤,其它作物也有减产的趋势。实践证明,只重视甜菜生产,不解决好后茬利用问题,就会产生“肥了甜菜,苦了后作”的恶性循环。随着农业生产的发展,如何解决好甜菜后茬利用问题,使其后作少减产或不减产,是当前生产上急需
Beet is one of the main cash crops in Anda County. In recent years, the planting area has stabilized at 23 million mu, accounting for 14.6% of the total cultivated land.
