What is the best variety of pomelo seedlings?

1. Majia pomelo

First, the monosaccharide content is high, and the sucrose content is low, so that although the sugar content is low, it has a fruity fragrance. Low sugar and low acid, soluble solids at about 10, titratable acid at about 0.9. The other is juicy enough, the juice yield is as high as 52.7%, even higher than the varieties used for juice processing. Third, it is rich in nutrition. Red flesh, rich in lycopene 23.5 μ g/gFW, rich in 17 different amino acids and iron, copper, zinc and other trace elements.

2. shatian pomelo

Leaves are thick, dark green, broadly oval or elliptical. Fruit pear shape or gourd shape, fruit top slightly flat, there are obvious ring and radial groove, pedicle narrow and extended neck shape, crisp flesh, sweet taste, but less water, many seeds.

2. Method of seedling raising of pomelo seedlings

1. acupoint planting preparation

Grapefruit tree planting point for the center to dig around the length, width and height of 1m big hole, let it weathering months after the green backfill. When backfilling, decomposed human manure or retting weeds, green manure and other organic fertilizers should be mixed into the soil layer of 20~40cm. Generally, if decomposed manure is applied to each plant in the planting pit, about 5 or 6 kg and calcium superphosphate is 1.5 kg, then topsoil should be filled on it. After backfilling, the planting hole is made into a mound with a vertical diameter of about 1m and a height of 20cm above the ground, and then a planting hole with a diameter of about 30cm and a depth of 30cm(depending on the root size of the seedlings) is dug at the planting point in the center of the mound for planting pomelo seedlings. Pomelo seedling roots should avoid contact with base fertilizer to cause rotten roots, and avoid direct contact with high concentration of base fertilizer.

2. Pomelo sapling preparation

Before planting, the bare-root pomelo seedlings should be properly pruned, all new shoots should be cut short, and then the remaining leaves should be properly cut off to reduce water evaporation; the roots should also be properly pruned, the long roots should be cut short, the wounds of the damaged roots should be cut flat, and the rotten roots should be cut short.

3. Pomelo planting method

When planting, put the pruned pomelo seedlings into the center of the planting pit, straighten the seedlings in a vertical posture, fill half of the fine topsoil around the roots, and then shake the seedlings slightly up and down to make the soil enter the gaps between the roots and better fit with the roots. At this time, you can adjust the height of the sapling again, so that the root neck is exposed to the soil surface, and then cover the soil again, fill the planting hole, and then gently shake the sapling a few times, cultivate the soil to the root neck, and use your feet to step on the soil obliquely from all sides to the plant direction. Do not step down vertically to avoid damaging the root system. And irrigation fixed root water, so that the soil and pomelo root full contact.

After planting, a disc soil bag about 3 cm higher than the soil surface and about 5~6 cm around should be built with broken soil within a radius of about 50 cm of pomelo seedlings for watering and liquid fertilizer application. Keep the soil moist, water it irregularly when it is dry, pull out the topsoil about 1 month or so, or sprout new roots, and apply urea or human urine gradually from dilute to thick to promote further growth of new roots.

4. fertilization

Fertilization is an important step in fruit tree planting. Generally, when the flowers bloom in warm spring, the small trees will begin to sprout. At this time, topdressing must not be too much, as long as fertilization is frequent. For seedlings within a year, fertilizer is generally applied twice a month. When the fruit trees grow up, more and more fertilizer will be needed. At this time, treated manure fertilizer or organic fertilizer can be applied appropriately.

5. post-management

Usually, small seedlings can bear fruit in the third year after planting. At this time, autumn management is mainly based on fertilization, and the base fertilizer must be applied sufficiently, so that the grapefruit tree can bear fruit better in the next year.

To sum up, the variety introduction and seedling maintenance points of pomelo seedlings, if you want to transplant pomelo seedlings, these knowledge must be clear in advance.
