How to manage before and after planting pomegranate and hanging fruit

I think everyone is very familiar with pomegranate. There are many kinds of pomegranate, and different kinds of pomegranate have slightly different tastes. There are also a lot of techniques and skills about the cultivation and cultivation of pomegranate. Let's learn about it with the editor.

How to manage before and after planting pomegranate and hanging fruit

The cultivated pomegranate cannot bear fruit after it blossoms for the following three reasons:

One is during its vegetative growth and flowering. Lack of light or coincides with cloudy and rainy weather; lack of light will cause plant vegetative growth to be relatively prosperous, which is not conducive to the accumulation of nutrients in the body, thus affecting reproductive growth, so it will fall off immediately after flowering; if there is continuous overcast and rain during flowering, the pistil can not be fertilized normally, resulting in its light flowering and can not bear fruit.

The second is the improper matching of fertilization. For Guanguo pomegranate, when applying topdressing, the three elements of nitrogen, phosphorus and potassium should be matched properly. if there is too much nitrogen fertilizer, less phosphorus and potassium fertilizer, and the plant lacks the necessary fruit nutrients, it may not be able to hang the fruit.

The third is during and before and after its flowering. If the potted soil is overwatered or the potted soil is too dry, the branches and leaves will grow wildly, or the nutritious fibrous roots will rot, and the blossoms will not hold the fruit; if the potted soil is too dry, the nutritious fibrous roots will shrink, and the flowers will not get enough water and nutrients, so they will inevitably fall, not to mention pollination and hanging fruit. If it is a fruit pomegranate that blossoms once a year, it will be very difficult to hang fruit again this year. Only by pruning the plants, increasing light, and controlling the supply of water and fertilizer, we can expect to blossom and bear good fruit in the coming year. If it is a "rose pomegranate" which can blossom many times a year, the potted pomegranate plants can blossom and bear fruit again by increasing light, topdressing phosphorus and potassium fertilizer, shrinking long branches to inhibit vegetative growth, pruning thin branches, ventilation and transparent light and other measures.

Propagation technology of pomegranate

1. Short branch cuttage: before sprouting, the pomegranate cut the disease-free annual and biennial branches from the strong mother plant as seeds, cut the seed into short cuttings with 2 to 3 nodes, cut the lower end of the cuttings into a smooth slope, and then soaked them in 40% carbendazim 300 times solution or 5% carbendazim 300 times solution for 10 to 15 seconds. Then soak the lower end of the cuttings in rooting powder solution for 5 seconds, or soak in 0.05% indole acetic acid solution for 2 seconds, or soak 0.05% naphthalene acetic acid solution for 3 seconds before cutting.

2. Long branch cutting: mostly used for direct garden construction or a small amount of propagation in the courtyard, the planting point is dug into a planting pit with a diameter of 60 cm to 70 cm and a depth of 50 cm to 60 cm. About 5 kg of mature soil fertilizer is used outside the pit and then mixed with topsoil. 2-3 1-2-year-old cuttings 80 cm to 100 cm long are inserted into each pit at an angle of 50 to 60 degrees from the ground and 40 to 50 centimeters deep into the pit. Then fill the soil while firmly, and finally irrigate and repair the tree plate, cover with plastic film or grass to preserve moisture.

3. Striping propagation: before sprouting, the sprouting tillers of the larger rhizosphere of the mother tree are cut around the base to promote the occurrence of roots, and then cultivate the soil from 8 cm to 10 cm to maintain soil moisture. After autumn, the rooting plants were cut off from the mother plants to form seedlings. The sprouting strip can also be bent and pressed into the soil of 10 cm to 20 cm in spring and cut several places with a knife to promote the new root, the top tip exposed and made it upright, then cut off the connection with the mother plant, dig seedlings with roots and plant.

4. Sowing and propagation: when the fruit is ripe from August to September, the seeds are taken out, rubbed to the outer seed coat, dried and stored. Sow the seeds from February to March in spring. Soak the seeds in warm water of 40 ℃ for 6 to 8 hours before sowing, and wait for the seed coat to expand before sowing. Sow the soaked seeds in the culture soil at a row spacing of 25 centimeters, cover soil 1 to 1.5 centimeters thick, cover with grass, and water once. After keeping the basin soil moist, the soil temperature is controlled between 20 and 25 ℃, and new buds and roots can be sent out after a month or so.

Cultivation techniques of pomegranate

1. Planting: pomegranate can be planted after falling leaves in autumn to before sprouting in the following spring. The soil should be sunny, leeward and slightly higher, and the soil should be loose, fertile and well drained. In the pot, the rotten leaf soil, the same soil and river sand mixed culture soil were selected, and an appropriate amount of mature organic fertilizer was added. Take soil mass when planting, trim the aboveground part properly, pour water thoroughly after planting, keep it in the shade, and move it to a ventilated and sunny place after germination.

2. Light: light and temperature are important conditions that affect the formation of flower buds. Full sunshine is required during the growing period, and the more abundant the light is, the more bright the flowers are. The leeward, sunny and dry environment is conducive to flower bud formation and flowering. When the light is insufficient, it will only grow leaves but not blossom, affecting the ornamental effect. The suitable growth temperature is 15-20 ℃, and the winter temperature should be lower than-18 ℃, otherwise it will suffer frost injury.

3. Water and fertilizer: pomegranate field cultivation must be reapplied with organic fertilizer once a year, and potted plants need to be fertilized for 1 to 2 years. In the growing season, we should also topdressing 3 to 5 times, and pay attention to loosen the soil and weed, often keep the basin soil moist, strictly prevent drought and waterlogging.

4. Pruning: the pomegranate needs to be pruned year after year, and can be formed into a single-stem round head shape, or a multi-trunk cluster shape, or a strong pruning into a dwarf flat-headed crown. In the fruiting period, the overgrown branches should be coring in summer and truncated after autumn to avoid secondary and tertiary branches at the top to store nutrients in order to form fruiting mother branches in the following year and cut off the sprouting in the rhizosphere in time.

5. Harvest: the seedlings propagated by cuttings or ramets of pomegranate began to bear fruit for 3 ~ 4 years, while the seedlings propagated by seeds took more than 10 years to blossom and bear fruit. Pomegranate blossoms 3 times a year, so it has 3 times of fruit, generally to head flower or two flowers and fruits develop well. It should be harvested in time according to variety characteristics, fruit maturity and climatic conditions.

The function of pomegranate

1. Deworming: pomegranate skin alkali has a strong killing effect on tapeworm and can act on the muscle of the worm, making it fall into continuous contraction. The concentration of pomegranine hydrochloride was 10000, and the tapeworm was killed in 5-10 minutes. It has been clinically proved that the combination of alkaloids and tannins has a better deworming effect, because tannins can turn alkaloids into insoluble and inabsorbable compounds, which can fully play a role on intestinal parasites.

2. Antibacterial: the decoction was diluted in test tube. 1V2560 and 1280 had inhibitory effect on Staphylococcus aureus, Shigella flexneri and Proteus, etc. It has obvious inhibitory effect on Vibrio cholerae, typhoid bacillus, Pseudomonas aeruginosa and Mycobacterium tuberculosis.

3. Antifungal: the water extract could inhibit 10 kinds of tinea fungi, such as Trichophyton corydalis, Trichophyton rubrum, Microsporum Audurum and Noca stellata, etc. by test tube dilution method at 1:4.

4. Antivirus: the experiment showed that pomegranate peel decoction could still inhibit influenza virus (influenza A PR3 strain) when diluted to 1: 10 000-1: 100 000.

5. Other effects: female rats or guinea pigs can reduce the pregnancy rate after taking pericarp powder. The aqueous extract of root bark can promote blood coagulation in rabbits.

Thus it can be seen that pomegranate has many functions, so we can make reasonable use of the value of pomegranate in our life. In the process of planting pomegranate, there are certain techniques in its cultivation and reproduction, as well as its management before and after hanging fruit. Only by mastering these technologies can the yield of pomegranate be improved.
