70年代前,斯里兰卡的马铃薯种薯完全依赖进口。高昂的成本和较差的适应性迫使斯里兰卡政府在70年代实行生产种薯的计划。最初,国家将由国外进口的种薯种植在发达地区的农场,使其扩大繁殖,生产出适于当地自然条件的标准种薯,作为下一季大面积种植的种薯。从此结束了全部进口种薯的历史,大大降低了生产成本。 Before the 1970s, potato seed in Sri Lanka was totally dependent on imports. The high cost and poor adaptability forced the Sri Lankan government to implement a program to produce seed in the 1970s. Initially, the state planted the seed potatoes imported from abroad on farms in developed areas to expand their breeding to produce standard seed potatoes suitable for local natural conditions as the seed potatoes to be planted in large areas for the next season. Since then, the history of all imported seed potatoes has been completed and the production cost has been greatly reduced.
