Detailed Explanation of the Seed Propagation Methods and Technical Points for Bird Cherry
Cultivating bird cherry by hand is not very difficult, and seed propagation can be used for artificial propagation. As long as you understand the growth habits of bird cherry, the survival rate of bird cherry seeding can also be greatly improved. The editor will introduce bird cherry seed propagation for you; friends who like bird cherry can learn about it together.
Bird Cherry (detailed introduction)
1. Seed collection
Select mother trees 20-30 years old, with good trunk form and free of pests and diseases. Collect in time around early July when the drupe skin turns from green to yellow, otherwise it is easily eaten by birds. Spread the collected fruit indoors to after-ripen for 4-5 days, until the fruit skin is soft, then rub off the fruit skin, rinse clean, dry indoors for 1-2 days, and store indoors in sand. However, because of the high-temperature season, seeds are very prone to mildew if stored improperly, so it is safer to sow immediately after collection, and the fruit skin does not need to be treated. The seed yield rate of drupes is about 20%, the 1000-seed weight is 50 grams, and there are 22,000 seeds per kilogram. The field nursery germination rate can reach 65%.
2. Raising seedlings
It is light-loving, cold-tolerant, and shallow-rooted, and can grow on slightly acidic, neutral, and calcareous soils. It is advisable to choose loose, fertile, well-drained sandy loam as the nursery site. When preparing the land, apply 1500 kilograms of decomposed organic fertilizer, 50 kilograms of phosphate fertilizer, and 10 kilograms of urea per mu. Drill sowing, with row spacing of 20-25 cm, sow at the end of February, with a sowing rate of 7.5-10 kilograms per mu, and cover with wolf's clothing grass after sowing. When sowing immediately after collection, seedlings can emerge in mid-March of the following year. After most seedlings have emerged, remove the grass in time; removing the grass too late easily causes tall-legged or bent-legged seedlings, affecting the seedlings.
July to August is the peak growth period for the seedlings, and after September they gradually slow down, and in late October the tops close and leaves fall. In the same year, the seedling height is 70-100 cm, the ground diameter is 0.6-0.8 cm, the part above the middle of the seedling is purplish red, and the seedling yield is 15,000-20,000 plants per mu.
Bird Cherry Seed Propagation Methods
Bird Cherry Seed Propagation Methods
Seed collection
The seed collection time for bird cherry is in mid-to-late August, and it can be collected when the fruit turns black. Soak the seeds in water, remove the seed coat and fruit pulp, wash clean with clear water, and dry the seeds in the shade.
Seed treatment
Mix the seeds with wet sand at a ratio of 1:3, then store them in a cellar at 0 to 5 degrees.
Sowing seeds
In spring, take the seeds out and place them in a cool place to germinate. When the seeds show white sprouts, they can be sown. The soil for sowing can be loose and fertile sandy loam. Apply sufficient base fertilizer before sowing. After sowing, cover with a thin layer of soil, compact the soil slightly, and water to keep the soil moist.
Thinning management
When the seedlings grow to a height of five cm, thinning can be carried out, removing the small and keeping the large, and pulling out weak, diseased, and damaged seedlings.
Fertilization management
During the seedling stage of bird cherry, carry out intertillage and weeding, and after thinning, carry out the first topdressing. After the seedlings grow larger, if the leaves turn red and black and the tips also turn red, it indicates sufficient fertilizer and water; otherwise, fertilize the plants in time to supplement nutrients.
Bird Cherry Propagation Methods and Main Value of Bird Cherry
Bird cherry is a deciduous tree of the Rosaceae family. Its inflorescence is long and beautiful and can be planted alone, in clumps, in groups, or in sheets. So what are the propagation methods of bird cherry? And what value does it have? Let's take a look together.
I. Complete Collection of Bird Cherry Propagation Methods
1. Bird cherry seed propagation
Seed collection: The seed collection time in the Liaoning area is around mid-to-late August. It can be collected when the fruit turns black. After collection, soak in water, remove the outer seed coat and fruit pulp by hand rubbing, wash the seeds clean with clear water, and dry them thoroughly in a cool and ventilated place to prevent the seeds from self-heating, mildewing, rotting, and losing vitality.
Seed treatment: Store the seeds in a cellar at 0-5°C. In late autumn, choose a dry, well-drained, sheltered and sunny place to dig a pit. The pit is 1.5 m deep, with 15 cm of gravel or coarse sand spread at the bottom, and a bundle of straw inserted in the middle of the pit for ventilation. The length and width of the pit depend on the number of seeds. Before storing the seeds, soak them in warm water at 40°C for 2 days, then mix the seeds with wet sand at a volume ratio of 1:3, put them into the pit, and fill until 20 cm from the ground, then backfill soil, with the filled soil 10 cm above the ground. Dig drainage ditches around it.
Sowing: In early April of the following spring, take the seeds out of the pit and place them in a cool place to begin germination. When 1/3 of the seeds show white sprouts, they can be sown. Choose flat terrain, convenient drainage and irrigation, deep soil, and loose sandy loam as the best. Before sowing, apply sufficient base fertilizer, preferably 50 kg per 667 sq m, carefully prepare the land and make ridges, the ridge surface should be flat, and irrigate enough bottom water. After the water has seeped away and the soil is slightly dry, use a hoe to make furrows, evenly broadcast the seeds, and the sowing rate is preferably 5 kg per 667 sq m. After sowing, cover with soil, preferably 1.5 cm thick, and after covering, press slightly, and thereafter keep the ridge surface moist.
2. Bird cherry cutting propagation
Bird cherry cuttings root easily. For its cuttings, hardwood cuttings are generally mostly used rather than softwood cuttings, because softwood cuttings have quite strict requirements for environmental conditions, especially temperature and humidity, and the transplant survival rate of softwood cuttings is also not as high as that of hardwood cuttings.
Collection of cuttings. In autumn, select healthy mother shoots of bird cherry that grew vigorously in the current year and are about 1 cm thick as cuttings.
Storage of cuttings. After collecting the shoots, cut the cuttings into 15-20 cm long sections, bundle 100 into 1 bundle, and place them in a cellar buried in sand. For cutting in the following spring. Take the cuttings out of the cellar and soak them in clear water for 2-3 days, then carry out upright cutting on the prepared nursery bed at a plant spacing of 15 cm and row spacing of 25 cm. After cutting, irrigate so that the cuttings are in close contact with the soil, promoting rooting and survival.
II. Main Value of Bird Cherry
Ornamental value: The young leaves of bird cherry are fresh green, and the old leaves are purplish red. When paired with other tree species, red and green contrast pleasingly. In gardens and scenic areas, it can be planted alone, in clumps, in groups, or in sheets, or planted as large colorful hedges and large flowerbed patterns. It can also be used as secondary street trees for urban roads and as landscape trees for community greening. It is also suitable for planting on lawns, corners, fork roads, hillsides, riversides, beside rocks, courtyards, in front of buildings, gate plazas, and other places.
Nutritional value: The protein content of bird cherry fruit is roughly similar to that of apples, containing 6.4% sugar, and also minerals and organic acids. Besides being eaten raw, it is mainly used to process products such as fruit juice, jam, and fruit wine. Bird cherry seeds contain 38.79% oil and can be refined into industrial oil; the leaves are used as medicine and can relieve cough. The leaves contain volatile oil and have an insecticidal effect. At a concentration of 1:8000-1:10000, it can reduce insect enzyme activity and cause death. The fruit tastes sweet and astringent, and can stop diarrhea and strengthen the spleen.
