Papaya belongs to short-day plants, and it will not blossom or bear fruit under long-day conditions. The growth of plants needs moderate sunlight. Papaya plants like humid climate conditions. Only by ensuring adequate water supply. Only in this way can we obtain high quality and high yield. When the vines grow to 150 cm, pick them again, leaving three grandchildren each. Pay attention to the adjustment of the shelf surface, and remove the vines in time according to the growth trend of the main vines to make the shelf surface evenly distributed. It is best to choose one with sufficient sunlight and good soil permeability. Fertile sand. Or planted on neutral land with weak soil viscosity. We should spread farmyard manure all over the land before preparing the soil. Then deep ploughing is carried out to increase soil fertility.

When the seed melon grows more roots, it is taken out of the plastic bag and transplanted into a large flowerpot for seedling raising. When the local temperature drops below 5℃, the roots will die, so the winter and spring temperatures in Jiangbei and East China are low, which is not suitable for planting. Papaya is a short-day plant, and it will not blossom or bear fruit in long sunshine. Bergamot needs loam rich in organic matter and good irrigation and drainage.
In March-April, melons are sown in cold areas, and seedlings are raised in flowerpots in hotbeds or film seedbeds at 20-25℃ for one pot and one melon to grow into big seedlings. After first frost, dig a big nest, remove the flowerpot and plant it permanently. If the plant is directly separated from the stem base (Laokun) of Chaenomeles in the previous year, Laokun, which has a large melon and high yield in the previous year, can be selected, and a pit can be dug near it to bury decomposed manure to promote more melon seedlings, and the seedlings can be cut and transplanted with a knife when they grow up.
