Sowing and Propagation methods of thick Plum

The difficulty of artificial cultivation of thick plum is not high, artificial propagation of thick plum can use the method of sowing, as long as we understand the growth habits of thick plum, the survival rate of thick plum sowing can also be greatly improved. The editor will introduce you to the sowing and reproduction of thick plum, and friends who like thick plum can understand it together.

1. Seed collection

The 20-year-old 30-year-old mother tree with good stem shape and free from diseases and insect pests was selected and collected in time when the drupe skin changed from green to yellow in early July, otherwise it was easy to be eaten by birds. The harvested fruit is ripened indoors for 4-5 days until the peel is soft, peel off, rinse clean, cool indoors for 1-2 days, indoor sand storage. However, due to the high temperature season, seeds are easy to mildew and rot when stored improperly, so it is appropriate to sow along with picking and sowing, and the pericarp does not need to be treated. The seed yield of drupe is about 20%, the weight of 1000 seeds is 50 grams, and there are 22000 seeds per kilogram. The germination rate of the nursery can reach 65%.

2. Raising seedlings

It is light-loving, cold-resistant, shallow-rooted and can grow on slightly acidic, neutral and calcareous soils. It is appropriate to choose loose, fertile and well-drained sandy loam as nursery land. During soil preparation, 1500 kg of rotten organic fertilizer, 50 kg of phosphate fertilizer and 10 kg of urea were applied per mu. Strip sowing, strip spacing 20-25 cm, sowing at the end of February, sowing 7.5-10 kg per mu, covered with wolf clothing after sowing. When sowing with picking, the seedlings can be unearthed in the middle of March of the following year. After most of the seedlings are unearthed, it is necessary to uncover the grass in time. Too late uncovering the grass can easily cause high-footed and bent-footed seedlings and affect the seedlings.

The peak period of seedling growth is from July to August, and it slows down gradually after September, and the top and deciduous leaves are capped in late October. In the same year, the seedling height is 70mm 100cm, the ground diameter is 0.6cm and 0.8cm, the seedling is purplish red above the middle of the seedling, and the seedling yield is 15,000 ~ 20,000 per mu.

Sowing and propagation methods of thick plum

Seed harvesting for sowing and propagation of thick plum

The seeds of thick plums are harvested in mid-late August and can be harvested when the fruit turns black. Soak the seeds in water, remove the seed coat and pulp, wash them with clean water and dry them in the shade.

Seed treatment

Mix the seeds with wet sand at 1:3 and store them in a cellar of zero to five degrees.

Seed sowing

In the spring, take out the seeds and put them in a cool place to promote germination. When the seeds appear white, you can sow them. The sowing soil can choose loose and fertile sandy soil, apply sufficient base fertilizer before sowing, cover the soil shallowly after sowing, slightly compact the soil, and watering to keep the soil moist.

Seedling management

When the seedlings grow to a height of five centimeters, you can carry out the seedlings, leaving the seedlings small and large, and pull out the weak seedlings, sick seedlings and injured seedlings.

Fertilization management

The weeding should be carried out in the seedling stage of thick plum, and the first topdressing should be carried out after the seedlings. After the seedlings grow up, if the leaves are red and black, the top is also red, indicating that there is plenty of fertilizer and water, otherwise the plants should be fertilized in time to replenish nutrients.

The main value of the Propagation method of thick Plum

Thick plum is a deciduous tree of Rosaceae, with long and beautiful inflorescences that can be planted alone, in clusters, in groups, and in pieces. What are the breeding methods of thick plums? What is the value? Let's take a look next.

1. A complete set of propagation methods of thick plums

1. Sowing and propagation of thick plum

Seed harvest: the seed harvest time is about the middle and last ten days of August in Liaoning area. When the fruit turns black, it can be harvested, soaked in water after harvest, the outer seed coat and pulp are removed by hand rubbing, the seeds are washed with clean water and thoroughly dried in a cool and ventilated place, so as to prevent the seeds from heating, mildew and rot and reduce their vitality.

Seed treatment: the seeds were stored in a cellar of 0-5 ℃. Late autumn choose dry terrain, good drainage, leeward to the sun to dig a pit, pit depth 1.5 meters anti-bottom 15 cm gravel or coarse sand, insert a bunch of grass handle in the middle of the pit in order to ventilation. The pit length and width depends on the number of seeds. Soak the seeds in 40 ℃ warm water for 2 days before storage, then mix the seeds with wet sand at 1:3, place them in the pit until they are 20 cm above the ground, and then backfill 10 cm above the ground. Dig drains around.

Sowing: at the beginning of April of the following spring, the seeds are raised from the pit and placed in a cool place to accelerate germination. When there are 1 stroke 3 seeds exposed, they can be sown. It is better to choose sandy loam with flat terrain, convenient drainage and irrigation, deep soil and loose soil. Sufficient base fertilizer should be applied every 667 meters before sowing. 50kg is appropriate, careful soil preparation for ridges, ridge surface should be flat, and sufficient bottom water should be irrigated. When the water seeps through, the soil dries a little, then pick up the ditch and evenly remove the seeds, with the sowing rate of every 667 square meters. 5 kilograms is suitable. Cover the soil after sowing, the thickness of the cover is 1.5 cm, after the cover is slightly suppressed, and the ridge surface should be kept moist in the future.

2. Cuttage propagation of thick plum.

Thick plum cuttings are easy to take root, and hardwood cuttings are generally used instead of softwood cuttings, because tender wood cuttings have strict requirements on environmental conditions, especially temperature and humidity, and the survival rate of transplanting is not as high as that of hardwood cuttings.

Collection of cuttings. In autumn, thick plum mother strips with strong growth and about 1 cm thick were selected as cuttings.

Storage of cuttings. After picking cuttings, cut the cuttings into cuttings 15 to 20 centimeters long, tie up 100 cuttings into a handful, and put them into the cellar and bury them with sand. The cuttings were cut in the following spring. The cuttings were taken out from the cellar and soaked in clean water for 2 days, then the cuttings were cut upright according to the plant spacing of 15 cm and the row spacing of 25 cm on the whole seedling bed, and then irrigated after cutting to make the cuttings closely connected with the soil and promote rooting and survival.

Second, the main value of thick plum

Ornamental value: thick plum young leaves bright green, old leaves purple-red, matched with other tree species, red and green match each other. In gardens and scenic spots, it can be planted alone, in clusters, in groups, or in pieces, or into large color hedges, and large flower bed patterns, and can also be used as secondary street trees on urban roads and landscape trees for greening in residential areas. It is also suitable for lawn, corner, fork road, hillside, riverside, stone side, courtyard, front of building, gate square and so on.

Nutritional value: the protein content of thick plum fruit is similar to that of apple, with 6.4% sugar and minerals and organic acids. In addition to raw food, it is mainly used for processing fruit juices, jams, fruit wine and other products. Thick plum seeds contain 38.79% oil, which can be used to extract industrial oil; leaves are used as medicine to relieve cough. Leaves contain volatile oil, which has insecticidal effect. The concentration of 1RV 8000LV 1RU 10000 could decrease the enzyme activity of worms and kill them on the surface. The fruit is sweet and astringent, which can stop diarrhea and replenish the spleen.

The above is the introduction of thick plum breeding methods and the main value of thick plum. I hope it will be helpful for everyone to breed thick plum. I also want to know other thick plum knowledge and continue to pay attention to us.
