The invention provides a cultivation method of rice sprouts and belongs to the technical field of vegetable cultivation. The method includes the following steps of 1, seed selection and soaking, 2, draining, 3, sowing, 4, germination accelerating and 5, greening in light; in the step 4, germination rice seeds are subjected to shading germination accelerating for 3-5 days, the temperature of a substrate in the germination accelerating process is 19-23 DEG C, water is sprayed 2-3 times a day, each time the water is sprayed, the substrate needs to be wet throughly, and when stem leaves grow to 8-10 mm, germination rice seedlings are obtained; in the step 5, the germination rice seedlings are cultivated in light, in the cultivation process, the temperature of the substrate is 19-28 DEG C, water is sprayed 3-6 times a day, when stem leaves of the germination rice seedlings grow to 70-110 mm, the germination rice seedlings are cleaned, the substrate is removed, and the rice sprouts are obtained. According to the cultivation method of the rice sprouts, the cultivation period is short, the obtained rice sprout stem leaves can reach 70-110 mm and are rich in chlorophyll, the edible taste is good, and the rice sprouts can be eaten as vegetables.
