How do pomegranate trees grow seedlings? Do pomegranate seedlings need to be grafted?

Abstract: Pomegranate trees are so good that one branch can be successfully cutting.

Over the years, pomegranates have become more and more popular in the market, and the number of growers growing pomegranate trees has gradually increased. How to raise pomegranate seedlings is also a concern for many fruit farmers. Here, the scientific rejuvenation of agriculture will explain the seedling raising of pomegranate trees.

How do pomegranate trees grow seedlings? The root system of pomegranate trees is not developed enough, and the transplanted pomegranate trees are prone to weak growth and late flowering and fruiting time. The seedlings of pomegranate trees are mostly propagated by cuttings, strips, and divides.

Pomegranate tree cuttings: The branches of pomegranate trees have strong rooting ability, and cuttings and seedlings are more propagated methods. Due to the different cutting methods used in the cutting process, there will be some differences in the cutting time.

Generally, the hard branch cuttings of the pomegranate tree are carried out in spring, and the green branch cuttings of the pomegranate tree are carried out in the autumn. Preparation needs to be done before cuttings, and the seedling site is best chosen in a sandy soil with fertile soil and good drainage.

Pomegranate tree hard branch cuttings: the cutting time is best selected between the spring equinox and Qingming every year, the collection of cuttings is best carried out before the flow of sap in the spring of each year, the pomegranate tree with strong growth and no pests and diseases is selected as the mother tree, and the one- to two-year-old branches are selected from the crown as cuttings. The length of the cuttings is controlled to about 15 cm, and 2 to 4 bud points are retained on each cutting.

The upper end of the cuttings is cut flat, and the lower end is obliquely cut. Afterwards, 50 to 100 cuttings are put together and soaked in the rooting solution. After the cuttings are processed, the cuttings are carried out according to the conditions of the nursery site.

Pomegranate tree green branch cuttings: The best time for pomegranate tree green branch cuttings is to choose the summer of July to September every year. Compared with hard branch cuttings, the time of pomegranate tree green branch cuttings is in summer, the temperature is higher, the air humidity is high, and the management of pomegranate tree cuttings after cuttings is more complicated, and the survival rate will be relatively low.

The length of the cuttings is also controlled at about 15 cm, the two green leaves at the top of the cuttings are retained, and the green leaves at the lower part of the cuttings are pruned off to avoid nutrient loss after cuttings. After cuttings, pay attention to keep the soil moist, and at the same time pay attention to shading, avoid sun exposure.

After the cuttings are completed, it is necessary to keep the soil moist and promote the rapid rooting of the cuttings. After the cuttings sprout, care should be taken to remove excessive tiller buds in time. At the same time, pay attention to reasonable topdressing and pest control.

Pomegranate tree seedlings are very simple, just sprinkle pomegranate seeds on the pot, maintain soil moisture, let it germinate automatically, and wait until it grows to about 10 cm.

There are many methods of pomegranate tree seedling raising, namely seed propagation and cultivation, strip cultivation, cuttings cultivation, and grafting cultivation. Seed propagation is very simple, that is, the selected pomegranate seeds are evenly sprinkled on the whole seedling ground, and then the seeds are covered with soil, watered once, and covered with a layer of straw or mulch. Strip propagation is generally to press the annual branch of garnet into the soil for cultivation, and wait until it grows a new root system before transplanting.

Cuttings propagation is to select high-quality, robust biennial branches of pomegranate trees, and insert them into the soil for seedling raising. Grafting propagation is more complicated, and it is necessary to select high-quality perennial pomegranate branches, graft them onto the selected rootstocks, and use grafting technology to cultivate seedlings.

Sowing seedlings is one of the most common propagation methods, which is generally suitable for the propagation of new varieties. The first thing you need to do in this method is to wake up the seeds, soak them in warm water for three to five hours, and then put them in the seedbed for seedlings raising. In about a month or so, germination will occur, and when the seedlings are ten centimeters tall, they will begin to colonize.

The use of lignified or semi-lignified green plants for cuttings breeding, generally select excellent mother plants with good quality results, and control nitrogen fertilizer, phosphorus fertilizer, and potassium fertilizer in September to promote the maturity of seedling branch tissue.

How pomegranate trees are cultivated, the appearance characteristics of pomegranate trees, and the meaning of the name of pomegranate treesDo you know?

Only pomegranates can be grafted, all kinds of pomegranates, because of biological isolation, plants of the same family can be grafted, and the pomegranate family is all pomegranates.

Pomegranate propagation techniques.

1. Short branch cuttings: Before pomegranate germination, cut from the robust mother plant of the tree without diseases and insects.

The first and second year-old branches are used as seed strips, and the seed strips are cut into short cuttings with 2 to 3 nodes, and the lower end of the cuttings is cut into a smooth and inclined plane, and after cutting, they are immersed in 40% carbendazim 300 times solution or 5% bacterium toxin 300 times solution and soaked for 10 to 15 seconds for sterilization. After that, the lower end of the cuttings is soaked in the aqueous solution of rooting powder for 5 seconds, or in the indoleacetic acid solution for 2 seconds, or in the naphthalene acetic acid solution for 3 seconds, and then cuttings.

2. Long branch cuttings: mostly used for direct garden building or a small amount of propagation in the courtyard, planting point digging diameter of 60 cm to 70 cm, depth of 50 cm to 60 cm of planting pit, outside the pit with humus soil miscellaneous fertilizer about 5 kg and then mixed with topsoil for standby, each pit inserts 2 to 3 1 to 2 year-old 80 cm to 100 cm long cuttings, the angle between the cuttings and the ground is 50 degrees to 60 degrees, inserted into the pit 40 cm to 50 cm deep, and then fill the soil while steady, and finally irrigate and repair the tree tray, cover the mulch film or cover the grass to protect moisture.

3. Strip propagation: Before germination, the tillers with large rhizosphere of the mother tree are circumferentially cut from the base to promote the occurrence of roots, and then 8 cm to 10 cm of soil are cultivated to maintain soil moisture. After autumn, the rooting plant will be cut off from the mother plant to become a seedling.

You can also bend the sprout tiller strip into the soil 10 cm to 20 cm in the spring and cut several places with a knife to promote new roots, the upper part of the top tip is exposed and make it erect, and then cut off the connection with the mother plant, and dig the seedlings with roots and plant them.

4. Sowing and propagation: Pick the fruit when it is ripe from August to September, take out the seeds, rub off the outer seed coat, dry and store it. Sowing seeds in February to March in spring, soak the seeds in warm water at 40 degrees for 6 to 8 hours before sowing, and wait for the seed coat to swell before sowing.

Soak the soaked seeds in the culture soil at a row spacing of 25 cm, cover with soil 1 to cm thick, cover with grass, and water it once. After that, keep the potting soil moist, and the soil temperature is controlled between 20 and 25, and new shoots and new roots can be sent out after about a month.

Extended Materials. Growth habits of pomegranates.

Pomegranate is native to the Balkan Peninsula to Iran and its adjacent regions, the world's temperate and tropical zone are planted, born in the mountains at an altitude of 300 1000 meters, like a warm and sunny environment, drought resistance, cold resistance, but also barren resistance, not tolerant, not waterlogging and shade, the soil requirements are not strict, but it is suitable for cultivation in well-drained sandy soil.

1. There are many ways to plant potted pomegranate seedlings at home, we plant first according to everyone's different preferences to choose the varieties of seedlings you need, pomegranates have agate pomegranates, large-flowered pomegranates, Taishan red pomegranates, pink sweet pomegranates, etc., generally as ornamental potted pomegranates can be selected for planting, if you prefer to eat, you can choose Taishan red pomegranate seedlings.

2. Potted pomegranates have high requirements for soil, and the potting soil must have high organic matter content, high air permeability and good drainage. When choosing soil, if there is no suitable soil around, you can go to a flower shop and buy it. Choose a mud pot with good drainage and high ventilation, if you feel that it is not beautiful, you can also choose a plastic pot, but pay attention to drainage, which is decided according to personal preferences.

3. Soak the saplings in water for half a day, insert them into the sandy soil, keep them moist, keep the seedbed in the environment of 20 25, and the branches can germinate and take root in 15 20 days, and the potted pomegranate saplings will be successful.

4. The best time to transplant seedlings is in mid to late March, put the bottom of the pot into the soil, put the seedlings into the pot, cover the soil on the seedlings by hand, water, and then fill the soil after the water penetrates, the soil does not need too much, 5 cm from the edge of the pot can call the wild. Finally, move the sapling into the sunny direction.

5. Pomegranates like fertilizer, apply more fertilizer when planting, but it is limited to the size of the pot, not too much each time, and the fertilizer is mainly organic fertilizer, which is imported in liquid form. Pomegranates are drought tolerant and must be watered more often during the summer months to keep the soil moist. Assisted pollination is required for pomegranate flowering, in May, and in the morning, if possible, in sunny weather.

6. The main hazard of potted pomegranate is dry rot, if dry rot occurs, the bad branches can be cut off, and then sprayed before and after the flowering period. The pests are mainly peach borers, which can be sprayed with 50% dichlorvos to eliminate the pest. After the result, it can also be added to the phosphine emulsion mixed with water into a potion for prevention and control.

The cultivation of pomegranate seedlings is best carried out in the spring 2-4 months or autumn 10-11 months, the cultivation soil requirements are loose and fertile and well-drained type, after digging the soil pit, the pomegranate seedlings can be planted in, pay attention to the cultivation of its root system Shu, after planting to water the root water.

1. Cultivation time

The cultivation of pomegranate seedlings needs to be carried out at a suitable time, pomegranate seedlings like to grow in a warm environment, generally it is best to cultivate in autumn in October and November or spring in February and April, and should not be cultivated in hot summer and cold winter, otherwise pomegranate seedlings are difficult to survive.

2. Soil requirements

When cultivating pomegranate seedlings, the soil requirements are loose and fertile and well-drained, if you are potting, we can use humus, garden soil and a small amount of river sand to mix and prepare, and you need to apply some well-rotted organic fertilizer to the soil before planting to improve the fertility of the soil.

3. Planting method

Prepare to grow strong pomegranate saplings, dig the soil out of a suitable size pit, put the pomegranate saplings in, and then fill the soil compacted, pay attention to planting, you need to soothe the root system of the pomegranate sapling, so that its root system can be closely in contact with the soil.

4. Maintenance management

After the pomegranate seedlings are planted, they need to do a good job of maintenance management, at this time, they need to be watered once to fix the roots, so that the soil is in a slightly moist state, which is conducive to the survival of pomegranate seedlings, if it is a potted plant, then it needs to be moved to a semi-shaded environment for a period of time, and then let it receive light after the pomegranate seedlings survive.

The cultivation of pomegranate seedlings needs to start from the aspects of soil preparation, variety selection, seedling raising techniques and maintenance work. The soil should be turned to ensure that it is soft and breathable, and the pomegranate varieties suitable for the local climate and environment should be selected, and the seedlings should be cultivated by stripping, sowing, cuttings or grafting, and transplanted in time.

1. Turn over the soil

To cultivate pomegranate seedlings, we must first prepare the soil suitable for its growth and development, so we must prepare the soil with a loose and porous structure, good drainage and ventilation ability and a certain basic fertility, and the soil itself can not have too many clay components, and it should be turned and disinfected before use.

2. Select the variety

There are many varieties of pomegranate, although this plant has a strong ability to adapt to the environment, but there are subtle differences in different regions, and its yield will be higher in a suitable environment, so it is necessary to choose pomegranate varieties suitable for the local climate and environment, and cultivate the corresponding varieties of seedlings.

3. Cultivation techniques

There are many ways to cultivate pomegranate seedlings, including the most natural and simplest, but the lowest survival rate of the sowing method, as well as the asexual propagation strip method, cuttings that can reproduce the female traits, and the grafting method of grafting with rootstocks.

4. Maintenance work

After the pomegranate seedlings grow to a certain size, they should be transplanted into the prepared suitable soil, and then properly watered and moisturized to ensure that the soil is moist but will not leave stagnant water, and the temperature control is done to prevent the soil from cooling down, and wait until the plants survive before they can start topdressing.
