Planting and maintenance of papaya trees

Papaya is also called wrinkled papaya. The flesh is tender white when raw, and becomes rosy when fully ripe. It is sweet and delicious when ripe, with a strong aroma, rich juice and moisture. It is planted in many areas. Here is an introduction to the planting and maintenance of papaya trees .

1. Seed germination

Choose a ripe papaya, break it open and take out the seeds, rinse off the mucus on the surface of the seeds with clean water, soak the seeds in 1% potassium permanganate diluted with water, take out the seeds and soak them in 25℃ warm water with the water level covering the seeds, put them in a cool environment, they will germinate in about 3 to 5 days, and then sow and raise seedlings immediately.

2. Sowing and seedling raising

The germinated seeds are sown into seedling bags at a depth of 3 to 5 cm, with two seeds sown in each bag. Then water until the soil is moist, and then make an arched film to cover it. The seedling temperature should be controlled between 20℃~30℃. When the papaya seedlings grow 6 leaves, you can apply thin nitrogen fertilizer once every half a month. Keep the soil moist during the seedling period. When the seedlings are more than 120 days old, they can be transplanted in the spring of the second year.

3. Site selection and land preparation

Choose a field with deep, loose and breathable soil, plow it 35 cm deep before winter, and expose it to the sun for a whole winter. A few days before planting in the spring of the following year, the land was prepared again. As papaya would grow larger in the later stage, the land was made into flat plots with a width of 1.5 to 2 meters, a ditch width of 50 centimeters, and a depth of 30 centimeters.

4. Planting

Papaya must be planted at an angle. When digging holes before planting, the hole depth should be 30 cm and the hole distance should be 2 meters. About 120 to 150 trees should be planted per mu. Apply 5 to 10 kg of rotted farmyard manure to each hole, mix the soil and rotted fertilizer evenly with a hoe, and water the holes thoroughly. Then take out the papaya seedlings, remove the seedling bags when planting, and plant the papaya seedlings at an angle.

5. Field management

After transplanting, keep the soil moist and water according to weather conditions. Pay attention to waterlogging prevention in summer and do not allow water to accumulate on the ground. In the first few years, the young trees are small and the spacing between rows is sparse. Pinellia, Corydalis, soybeans, vegetables or other dwarf crops can be planted between the rows of trees.

In the first spring after transplanting, no top dressing is needed. Fertilize around the plants in late autumn and early winter, applying less fertilizer for small trees and more fertilizer for large trees. Apply 10 to 20 kilograms of soil and fertilizer to each mound of mature trees and cover with soil after application. When it blooms and bears fruit 3 to 4 years later, apply fertilizer every autumn. In addition to soil and miscellaneous fertilizers, you can also combine it with quansu and superphosphate, and water the plant after application to promote fruiting.

Weeding should be done 3 to 4 times in spring and autumn every year to eliminate weeds. In winter, add soil to the roots of the trees to prevent frost. Papaya branches grow in clusters and need to be pruned before they sprout in spring. Cut off old and dense branches and leave strong branches. The branch density is required to be moderate, hollow inside and round outside to facilitate ventilation and light transmission, and increase the fruiting rate.

6. Pest and disease prevention

Papaya has a very strong disease resistance, and with good management, there are basically no diseases and pests. However, we must do a good job of prevention. There are many pesticides that can be used to prevent papaya diseases and pests. You can use carbendazim and thiophanate-methyl. For insect pest prevention, you can use dichlorvos and DDVP. Spray once every week, and spray 2 to 3 times in a row will do. Please use the pesticide according to the instructions.

That’s it
