What is papaya?

II. Management techniques of papaya trees

1. Planting density management

Papaya can be planted in spring and autumn. When sprouting, the root tillers and sprouts within 30 cm of the trunk should be removed in time, and a part of the overdense shoots should be properly removed.

2. Water and fertilizer management

Base fertilizer is usually applied in autumn, which accounts for about 80% of the total fertilizer application in the whole year. Fertilization should be carried out according to the specific growth status of papaya trees, and fertilizer before and after flowering and fruit expansion should be applied in time during the full fruiting period. young trees can reduce the amount of fertilization, watering once after fertilization, and water control during flowering.

3. Field management

In the first and second years of papaya, the flowers should be picked at any time. In the spring of the third year, the management of flowers and fruits should be strengthened, fertilizers for various periods should be added, and the fruit rate of self-pollination is high. If artificial pollination or honey is put into bloom, the fruit setting rate can be greatly increased. If the pollination is not good, it will cause the fruit to fall off automatically, so it is only necessary to get rid of the deformed fruit and the poorly growing fruit every year after setting the fruit.

4. Proper pruning

In the growing season, we should pay attention to pruning off some competitive branches, over-dense branches, thin and weak branches, disease and insect branches and long upright branches in the crown. After papaya grafting, the middle stem branches are more upright and can be trimmed into a cup shape with a little pruning. There are many other shapes, but they are usually slender. If it is lack of branches, several buds can be retained and then re-truncated to promote branching.

5. Disease and pest control

The main diseases of papaya are dry rot, leaf spot, ring disease, pests are mainly aphids, red spiders, spider moths, and so on. Spraying with medicine can help papaya trees get through the disease stage and clean up the orchard after the beginning of winter. concentrate all the dead branches and leaves and destroy them.
