Propagation methods of papaya

Papaya is a kind of fruit that we are all familiar with, which is produced in most provinces of our country. The ornamental nature of papaya plant is relatively high, the fruit taste is relatively astringent, but it has many effects, such as relieving alcohol and expectoration, relieving qi and stopping dysentery, etc., now the planting area in our country is relatively large. So how to reproduce papaya? The following editor brings you the breeding method of papaya, let's have a look!

1. Ramet propagation

The root of papaya is shallowly distributed, so it has a strong tillering ability, and many tillering seedlings can often be seen at the base of the plant. Therefore, ramet propagation is a commonly used method of propagation of papaya. Ramet propagation is usually carried out in February-April and September-October every year. First of all, around the plant, we should select biennial young plants with a height of about 45 centimeters, take them out with their roots, dig them out and simply deal with them before they can be planted. If it is an one-year-old small tiller seedling, it can be transplanted to the nursery and can be planted about a year later.

2. Cuttage propagation

Cutting propagation is also suitable for the propagation of papaya. Every year from February to March, when the spring buds of the papaya tree have not yet germinated, choose a good papaya tree and cut off the two-year-old strong branches on it. Then it is divided into small segments about 18 cm long, each retaining about 3 sections. Then the cuttings can be directly inserted into the nursery bed, and the row spacing can be controlled around 15*10cm. After cutting, the compacted soil is properly watered, and then covered with a layer of film to improve the soil temperature and moisture retention capacity. The cuttings will gradually take root around Ching Ming Festival. At this time, you can uncover the film, do a good job in fertilizer and water management, and strengthen the work of loosening the soil and weeding. In about a year, the seedlings can grow to about 90 centimeters.

3. Sowing and reproduction

Sowing can be in autumn or spring. Autumn sowing should be carried out in late October, when the papaya fruit is ripe, pick the fruit and then take out the seeds, wash the mucus off the seeds and sow directly. The row spacing of the sowing ditch is controlled at about 25 cm and the depth is maintained at 4 cm. Then spread the seeds evenly into the sowing ditch. Seedlings will emerge in the spring of the following year. Spring sowing time is from March to April every year, first soak the seeds in clean water for about two days, and then wrap them in a wet cloth at a temperature of about 25 degrees for a whole day. Then, according to the autumn sowing method, the seedlings will generally emerge before and after Ching Ming Festival, and they can be planted when the seedlings grow to about one meter.

The above is a brief introduction to the breeding methods of papaya. There are many breeding methods of papaya, we should choose reasonable breeding methods according to the weather, planting scale and other actual conditions to ensure the yield of papaya. That's all for today's introduction. This article is for reference only. I hope it can help you all.
