由于传统莲藕种植费时占地，繁殖系数低。运输成本高，优良品种不易推广。由武汉市蔬菜研究所水生研究室科学家们，经过多年研究终于培育出世界上首支试管藕，这支长仅 5mm的绿色藕节每年理论上可以繁殖 100万个藕芽，从而为莲藕的产业化生产提供了前所未有的机遇。 　　试管藕 Due to the time-consuming traditional lotus root planting, breeding coefficient is low. High transportation costs, not easy to promote good varieties. By the Wuhan Vegetable Research Institute aquatic laboratory scientists, after years of research finally cultivate the world’s first test tube lotus root, the only 5-year-long green lotus root theoretically can breed 1 million lotus root buds, so as to the lotus root industry Production provides an unprecedented opportunity.
