“红豆”又名“相思子”,是一种植物,结出来的果实颜色鲜红,可用来作装饰。“南国”就是指中国的南方。“采撷”是“采摘”的意思。
“红豆(Hóngdòu)", red berries, has another name: "seed of memories". It is a plant which produces red seeds which can be used for decoration. "南国(Nánguó)", South Country, refers to the south of China. "采撷(cǎixié)" means to harvest. 

整首诗的意思是:在你居住的遥远南方,生长着美丽的红豆。春天又一次到来,不知道它们发了多少新枝?唯愿你能多多地将它们采下,红豆最能寄托朋友之间的相思。
The whole poem means: Beautiful red berries grow in the far away south, where you live right now. Spring comes again. I don't know how many new branches they have. I only hope you can gather them. These red berries are symbols of friendly love.
