Seed collection: papaya can be harvested when the exocarp is bluish yellow from August to September, cut open the fresh fruit, take out the seeds to be cool and dry, select the full seeds, and also cut the fruit to take out the seeds after the pericarp is air-dried in November.

2. Sowing time: papaya can be sowed in spring or winter, sowed in spring from February to April, planted from April to May, seedling stage 50-70 days, winter sowing from mid-October to early December, seedling stage 120-130 days, we should pay attention to adopt cold protection measures.

After soaking, the seeds were picked up, drained and mixed with sand, sowed in the seedbed according to the row spacing of 20 cm, covered with thin soil and covered with straw, kept moist, and the seedlings could emerge in 40 days and 50 days.

4. Seedling stage management: papaya should cultivate soil and moisturize after emergence, reduce watering when growing 2-3 leaves, promote deep root and prevent overgrowth, apply thin fertilizer at 4-leaf stage, start seedling refining at 5-leaf stage, stay in bed or plant in field in the next spring.
