Scientific planting and cultivation techniques of papaya

Papaya is a kind of good beauty and health fruit. With the popularity of papaya as a fruit, growing papaya has become a choice for more and more farmers. Planting papaya is the same as growing other fruits and vegetables, the planting techniques and cultivation points are very important, so let's take a look at it with the editor.

Scientific planting and cultivation techniques of papaya

1. Soil: papaya trees do not have strict requirements on soil quality, and grow well in sandy soil with deep soil layer, loose and fertile soil and good drainage, and should not be planted in low-lying water accumulation places.

2. Moisture: papaya trees like to be semi-dry and semi-wet. If the soil is too wet before and after flowering, the flowering period will be short. After seeing the fruit, the fruit will be dry and shrunk, and if the soil is too wet in the fruit ripening stage, the fruit will fall.

3. Light: papaya trees are not tolerant to shade, and the planting land can choose to stay away from the wind and the sun.

4. Temperature: papaya trees like a warm environment and can spend the winter in the open field in the Yangtze-Huaihe River Basin.

Propagation methods of papaya seedlings

1. Cutting: when cutting, papaya is selected from the mother tree for 1-2 years, fully developed, disease-free and completely lignified branches as cuttings, cut the lower end near the node into a bevel, and quickly dip it in 0.05% rooting powder for 10 minutes and 15 seconds. Take it out and dry it for a little bit.

2. Tillering: many sprouting seedlings grow around the rhizosphere of papaya, which can be planted with strong seedlings with a height of more than 60cm and 80cm from September to November. the survival rate of seedlings obtained by this method is high, but the propagation coefficient is low.

3. Striping: in spring or autumn, papaya strips are selected to bend down the branches that are robust, disease-free and near the ground, press into the soil, cut part of the soil, fix it with wooden branches, and then pile the fertile soil on it. After the ring cutting, the roots are separated into separate seedlings.

Prevention and control of diseases and insect pests of papaya

The main diseases of papaya are leaf spot, ring disease, anthracnose, dry rot, pests are aphids, red spiders, papaya borer, peach heart borer, pear planthopper, diamondback moth and so on.

Control methods: spray imidacloprid EC 3000 times in early March, spray 30% peach Xiaoling EC 500 times and 50% carbendazim wettable powder 600 times 800 times respectively from late May to early June and early July to control papaya borer, diamondback moth, peach heart borer and leaf spot. From late July to before defoliation, 70% mancozeb 800 times solution, 50% carbendazim wettable powder 600 times 800 times solution, equivalent Bordeaux solution and other fungicides were sprayed alternately for 3 times for 4 times. At the same time, pay attention to the control of all kinds of caterpillars, pear planthoppers and other pests. Clean up the orchard after winter, sweep away fallen leaves, stiff fruits, disease and insect branches, and concentrate on burning.

The value of papaya seeds

1. Economy: fresh papaya fruit contains more tannins and organic acids, and the sugar content is relatively low, which makes it sour and unsuitable for raw food, but its fruit is rich in nutrition and vitamins, which can be made into products with unique flavor.

2, health care: the health function of papaya is obvious, with papaya as raw material, the main products that have been successfully developed and listed on the market are papaya juice beverage, papaya candied fruit, papaya fruit wine, papaya fruit vinegar and so on.

3. Edible: the delicious papaya has the effect of dietotherapy, relaxing muscles and activating collaterals, and stomach dampness, especially for women, and more importantly, the active ingredients in papaya fruit can improve the function of phagocytes.

4. Viewing: papaya is often used as an ornamental tree species because of its beautiful tree appearance, concentrated flowers, large number of flowers and beautiful flowers. It can also be used as a rootstock of grafted begonia, or cultivated in the courtyard or garden as a bonsai.

The cultivation of papaya needs to provide proper sunlight, moisture, fertilizer and temperature for papaya according to the environmental requirements of papaya. In addition, pest control of papaya is also a key factor to ensure the yield and quality of papaya, and growers need to focus on it.
