What are the latest seedling raising methods of papaya?

Papaya has high medicinal value, and also has excellent edible and medicinal value. It is also cultivated as a garden ornamental plant in many areas with good economic benefits. And as more and more people grow it, how does papaya grow seedlings? Let's take a look at it together with Xiaobian.

1. Seedling cultivation

First of all, we should select fully mature fruits from healthy mother plants, clean them after taking out their seeds, dry them in the shade and put them into bags with good air permeability, and store them in a low temperature and dry environment. Autumn sowing can be cleaned seeds directly open shallow ditch drilling, spring sowing should be sand storage treatment. After sowing, the soil should not be too thick, preferably three times the seed diameter, too thick soil may lead to slow or even no emergence of seeds. After sowing, water should be sprayed to keep the soil moist. When the seedlings grow to 3 true leaves, thinning should be carried out. When they grow to 6 true leaves, fertilizer and water management should be strengthened. Fertilizer spraying and ground spraying should be combined. In addition, the new technology of bud seedling transplantation popularized in recent years is generally welcomed. First, seedlings are raised in the seedling field, and then transplanted to the field when the seedlings grow to 3 leaves. This method of seedling emergence is neat, lateral roots are developed, and the seedling rate is high.

2. Cultivation of grafted seedlings

The scion of grafted seedlings should collect the 1-year branches with full growth and development and no diseases and pests on the excellent plants of varieties. The scion used for grafting in spring should be picked up during the winter dormancy period and buried in wet sand for storage after picking; while the scion used in summer does not have so many problems. It can be used as it is picked, cut off the leaves, keep the petioles and wrap them with wet cloth. In spring grafting should be carried out 20 days before rootstock germination, tongue grafting, splitting and other methods can be used; in summer and autumn, T-shaped bud grafting or bud grafting with xylem can be used, and the plant height of rootstock should be above 50 cm. After grafting, the survival rate should be cut off frequently, and those that are not survived should be reconnected in time. When the new shoots grow to 30 cm, they should be untied. At the same time, fertilizer and water should be strengthened to control weeds and pests. They can be taken out of the nursery in the same year.

3. Cutting seedlings

Similar to grafting, the branches used for cuttage should be selected from 1~2-year-old branches with rich tissue and full leaf buds on excellent mother plants, cut them into 15-25 cm long, leave 2-3 nodes, cut flat at the upper end from the terminal bud 1 cm, cut into inclined planes near the axillary buds at the lower end, and store them in moisture for later use. Green cuttings can be picked in the growing season, harvesting semi-lignified branches, cutting into 15-20 cm, removing the lower leaves can be. Cuttings should wait for the ground temperature to reach more than 15 degrees, summer is generally carried out in June-August, when appropriate shade and moisture are needed. The survival rate of cuttings treated with rooting agent before cuttage could be obviously increased.

The above is what papaya seedling methods are introduced, I hope to help you, want to know more about the relevant knowledge, please pay attention to us.
