The present invention relates to the technical field of Luo Han Guo cultivation, in particular to a method for cultivating Luo Han Guo. The branches are collected and sterilized, and the stem apex meristem is cut out for subculture; the seedlings are selected and quickly dipped in IBA, and the lower 1/4 of the seedlings are inserted into the Between two pieces of filter paper, clamp the filter paper with two aluminum alloy bedding bars, and fix the aluminum alloy beading bar with a small clip, then hang the aluminum alloy beading bar on the two walls of the rooting incubator for rooting cultivation, and the rooting incubator contains a box volume of 1 /4 or 1/2 MS culture solution; before transplanting, apply quicklime to the planting site, and then apply decomposed farmyard manure, place the seedlings in the planting nest and pour enough water for rooting, after 7 days, wet the fertilizer once a week, When the Luo Han Guo seedling grows more than 3 true leaves, remove the film covered on the Mirs, and apply organic compound fertilizer, the method of the present invention obtains transplanted seedlings, the stems are strong, the rooting rate is high, the quality is good, and the survival rate of field transplantation is high. High and adaptable.
