✔ 最佳答案
There's no maximum number of crops. Plantations can grow as many crops as the find profitable.
Traditional plantations also grew produce for use by the people on the plantation (the owners and the workers), such as vegetables, grains, meat animals, fiber plants like cotton or flax, timber, etc.
There is no standard land size for one crop or for a whole plantation, either. It all depends on what the owners and managers think will do best and sell best, in light of how much land they have and what size work force they have available.
