核心问题
（1）Farmers grow cotton in Shandong.
(2) This year alone, we've already planted ten thousand trees.
grow 和 plant 都作“种植”解, 它们有没有区别?
词典解答
及物动词 grow 泛指“种植、栽种”，通常与表示庄稼、花、草的词语连用；而及物动词 plant 则特指“移植、移栽”，通常与表长成苗的植物的词语连用：
-
We grow potatoes and carrots in our garden. 我们在园子里种了些土豆儿和胡萝卜。
-
Japanese farmers grow rice. 日本农民种水稻。
-
We planted some roses in the garden. 我们在花园里种了些玫瑰。
上面的区分只是个大体趋向,有时人们也使用 plant 来泛指“种植”:
If they leave some of their fields free and do not plant anything, they will still receive money from the EU. 如果农民把有些农田闲置起来，不种任何作物，他们仍然可以从欧洲联盟得到钱。
