< p >这完全取决于你农业作物。注意例如多少葡萄园(尤其是欧洲,从我的观察)坐落在陡峭的山坡上。在其他地方,如美国东北部,你可能会在山上农场奶牛,或者种枫树。IOW, conventional farming of annual crops on hillsides is labor-intensive (and the soil tends to be poorer), so you grow things that don't need annual plowing & planting, like grape vines or fruit trees such as olive: http://www.oli-de-mallorca.com/cultivation-olive-grove-majorca.html If you are doing the plow & plant thing on hillsides, you use contour plowing https://en.wikipedia.org/wiki/Contour_plowing or terracing, otherwise heavy rains will soon erode your soil.
