1、 Soil

Papaya has strong adaptability to soil, but it is best to choose loose, fertile and weakly acidic sandy or alluvial soil. Usually, the soil should be loosened frequently to maintain the permeability of the soil. The most common way is to apply sulfate fertilizer to the soil, such as ammonium sulfate and potassium sulfate, which can slowly acidify the soil

2、 Illumination

It has high requirements for light, and should ensure sufficient light every day. Under the condition of insufficient light, the stems are thin, the internodes and petioles are long, the leaves are thin, and the flower buds are poorly developed. However, in the high temperature and strong light season in July and August, proper shading should be considered to avoid the quality of fruits affected by sunburn

3、 Temperature

It likes a warm climate, and the annual optimum temperature suitable for its growth is 22-26 ℃. The temperature is about 10 ℃, the growth tends to be slow, the young organs begin to suffer from freezing injury at 5 ℃, and the leaves wither at 0 ℃. High temperature is also harmful to growth

4、 Watering

Keeping the surrounding environment moist is conducive to its growth. It should be watered in time during summer drought. Sprinkler irrigation, drip irrigation and other diversified methods can be applied, and irrigation is recommended if conditions permit

5、 Fertilization

Because its growth needs more nutrients and trace elements such as Ca and K, regular fertilization is essential. It is suggested to water livestock manure or rotten cake fertilizer once a year before the beginning of spring and winter, so as to make it grow healthily

6、 Precautions

1. In the whole year, we should carry out intercropping and weeding for 4-5 times, so as to greatly increase the permeability and nutrient supply of the soil and contribute to its growth

2. The main pests are red spider and snail. Pesticides should be sprayed regularly for pest control
