The invention discloses a method for cultivating phyllanthus emblica seedlings in an indoor soilless mode. The method comprises the following steps that 1, devices are prepared, wherein the devices comprise a seedling raising tray, a cultivation frame, a sprayer and a luminescent lamp; 2, seed soaking and germination are conducted, wherein phyllanthus emblica grains are soaked in clear water of 20-30 DEG C for 6-10 hours, after infiltration, the grains are fished out and put into a germination cylinder, the top opening is closed with a cover, the constant temperature ranging from 28 DEG C to 30 DEG C is kept to accelerate germination for 2-3 days, and a small amount of clear water is sprayed and added during germination acceleration till shoot tips come up; 3, transplanting is conducted, wherein after the shoot tips grow to 0.3-0.5 cm, seed buds are scattered on a net of the seedling raising tray and spread flat; 4, cultivation management is conducted, wherein clear water is sprayed once every 6-8 hours, a nutrient solution is sprayed once every 20-24 hours, the nutrient solution contains 0.5% of urea, 0.3% of potassium chloride and 0.2% of calcium dihydrogen phosphate, illumination is kept for 15-18 hours, and the indoor temperature is kept at 25-30 DEG C; 5, buds grow, and when bud seedlings grow to 10 cm to 13 cm, transplanting can be conducted on the bottom wall according to the buds.
