This invention relates to the field of crop cultivation technology, specifically to a method for in vitro culture of taro sprouts in a substrate. The method involves selecting uniform, disease-free taro tubers weighing 15-25g each as seed tubers and pre-treating them with sterilization. After sprouting, the seed tubers are cut. When the new sprouts are 1-2cm long and have 2-3 roots, the main bud is cut off along the lower edge of the new roots. This main bud is placed in a vegetable seedling substrate for seedbed cultivation to obtain seedlings, with temperature and humidity controlled during the cultivation process. When two new leaves have grown and the plant height is 8-10cm, the seedlings are transplanted for field planting. After transplanting, soil moisture is controlled to complete the planting process.
