农业学大寨的群众运动蓬勃发展,农业要大干快上。黑龙江省1980年粮食总产翻一番和粗改细、旱改水、一季改两季的高产稳产任务,給农业生产和科学实验提出了许多急待解决的问题。提高作物总产的途径,一是扩大耕地面积,包括开荒和提高复种指数;一是提高单位面积产量。地少人多地区,开荒潜力不大;即使荒原较多,同样应该把提高单产和增
Agriculture Dazhai’s mass movement is flourishing, and agriculture must be faster and faster. Heilongjiang Province in 1980 doubled its total grain output and coarse to fine, drought to water, two quarters of a quarter to change the high yield and stability of the task, to agricultural production and scientific experiments put forward many urgent problems to be solved. The ways to increase total crop production include expanding the area of cultivated land, including opening up wasteland and increasing the multiple cropping index. The first is to increase the yield per unit area. There are not many potential land reclamation areas in the areas where there are fewer people and more land. Even if there are more wilderness areas, the same should be done to increase yields and increase
