Papaya has strong adaptability to soil, but it is best to choose sandy or alluvial soil with loose, fertile and weak acidity.Usually, soil should be loosened frequently to maintain soil permeability, the most common way is to apply sulfate fertilizers to the soil, such as ammonium sulfate, potassium sulfate, etc., which can slowly acidify the soil.
It has a high requirement for light, and sufficient light should be maintained every day.Under the condition of insufficient light, the stem is thin, the internode and petiole are long, the leaf is thin, and the flower bud is poorly developed.However, in the high temperature and strong light season of July and August, appropriate shading should be considered to avoid sunburn and affect the quality of fruits.
It likes warm climate, and the best annual temperature for its growth is 22-26 degrees Celsius.At about 10 , the growth tended to be slow, the young organs began to freeze at 5 , and the leaves withered at 0 .Too high temperature is also harmful to growth and development.
Keeping the surrounding environment moist is conducive to its growth, and it should be sprinkled in time during the dry period of summer.Sprinkler irrigation, drip irrigation and other diversified ways can be used, and irrigation is recommended when conditions permit.
Because its growth needs more nutrients and trace elements such as CA and K, regular fertilization is essential.It is suggested to irrigate livestock manure or decomposed cake fertilizer once a year before early spring and winter, so as to make it grow healthily.
1. Intertillage and weeding should be carried out 4-5 times throughout the year, so as to greatly increase the permeability of soil and nutrient supply, which is conducive to its growth.
2. The main insect pests are red spider and snail.Pesticides should be sprayed regularly and regularly for pest control.
