Sowing can use 128 hole hole tray, substrate adopts imported peat, add 10% large-grain pearlite with diameter of 3~5mm, keep medium moisture of substrate, not too wet, sprout in 5 to 10 days.

The breeding cycle is 5 to 6 weeks, divided into 4 stages. The first stage is from sowing to radicle emergence, and the second stage is from radicle emergence to cotyledon extension, germination is complete and a true leaf grows. After emergence, it is necessary to reduce the humidity of the substrate to facilitate root development. In the third stage, a true leaf appeared and began to grow, reaching the transplanting standard. The fourth stage is preparation for transplantation or storage. The germination temperature of the first stage is 21℃~24℃, which takes 3 to 5 days, and the substrate should be moderately moist. In the second stage, the temperature is 21℃~24℃, the fertilizer can be applied once a week, the N∶P∶K ratio is 15∶0∶15 and 20∶10∶20 alternately, the concentration is 50~75ppm, it takes 5 to 10 days, and the medium is wet. In the third stage, the temperature is 18℃~21℃, the fertilizer concentration is 100~150ppm, and the fertilizer is applied twice a week.

The temperature of the fourth stage is 17℃~18℃, it takes 7 days, and the fertilizer concentration is the same as that of the third stage. After that, it can be planted in 14cm×12cm pots.

The pH value of the water should be adjusted to slightly acidic, between 5.5 and 6.5 is good, and the pH value of the matrix should be controlled between 6.2 and 6.5. Temperature During the whole seedling period, the substrate temperature should not be lower than 18℃, and the growth and development of seedlings should be hindered if the temperature is too low.
