How to plant cherry trees with cherry blossom seeds

Although the survival rate of planting cherry blossoms with cherry seeds is not as high as that of other methods such as cuttings and striping, its cost is the lowest of all methods, and it can still survive as long as it is properly maintained.

Growth habits of cherry blossoms

Like light, slightly resistant to shade, like deep, fertile, well-drained slightly acidic soil, not resistant to salt and alkali, like the environment with high air humidity, but avoid stagnant water and low-lying land, have a certain degree of cold resistance. The root system is shallow, the branch healing ability is poor, avoid heavy pruning. The resistance to hydrogen fluoride is strong, the resistance to ozone is moderate, and it has certain blocking ability to smoke and dust.

How to plant cherry trees with cherry blossom seeds

Soil selection and preparation: Cherry blossoms are shallow root positive tree species, and 60% of their roots are distributed within 60 meters of the surface, and mainly in the topsoil layer of 20 meters. Therefore, the planting land must choose open and sunny land with good drainage, loose soil and good ventilation, avoid stagnant water and dryness, and avoid people, animals and vehicles stepping on the soil around the tree, especially in the distribution range of the root system, which will compact the surface layer of the soil. affect the growth of roots, shorten life, and even lead to death.

Sowing and propagation: flowering in April, ripening in July. After the fruit is ripe, it is reclaimed and mashed, the pulp is separated from the seedling seeds by rinsing, and the seedling seeds are dried and stored in wet sand to be sown in the following spring, and the germination rate can reach 80%.

Rational fertilization: during the growing period, cherry blossoms are fertilized twice a year, and acid fertilizer is better. One was winter fertilizer, which applied organic fertilizers such as bean cake, chicken manure and mature fertilizer in winter or early spring, and the other applied quick-acting fertilizers such as ammonium sulfate, ferrous sulfate and calcium superphosphate after falling flowers. In general, the method of hole application can be adopted for big cherry blossom trees, that is, at the edge of the positive projection line of the crown, dig a circular ditch about 10 meters deep and apply fertilizer. This method is not only simple and beneficial to root absorption, but also increases the diameter and depth of ring trench with the growth of trees.

Wound disinfection: after the branches of cherry blossoms are injured, the wound heals slowly. According to this characteristic, the pruning of cherry blossoms should be especially cautious, and some overlapping branches, disease and insect branches should be pruned mainly. After pruning, it is necessary to disinfect the wound with medicine in time to prevent rain, germs invading the wound and decay, and the effect of antiseptic is better.

Cross-pollination: cross-pollination is the main way to form cherry blossom varieties, and even form intergeneric hybrids. We should make full use of this characteristic to select more and better cherry blossom varieties.

Shaping and pruning: the crown of general cherry blossoms is shaped into a natural happy shape. The method is that when cutting in winter, the trunk is set at 60 to 80 centimeters, and in the shaping zone at the top of 20 centimeters, three or four main branches are selected, the main branches should be evenly distributed and properly positioned, and the rest of the branches should be erased. When the left main branch is 30-50 cm long, it is cut short to promote the branch, so that when it is cut in winter next year, the lateral branches on the main branch can be selected with uniform distribution and suitable position.

Pest control: when gummy moths drill into the trunk to lay eggs, they can dig out the eggs with a sharp knife, improve the soil and strengthen the management of water and fertilizer. The roots of diseased trees such as nodule disease cannot grow normally, and no matter how much fertilizer is applied, the tree is still not strong. It is necessary to remove the tumor in time, carry out soil disinfection, and use rotten leaf soil, charcoal powder and microorganisms to improve the soil. Diseases and insect pests such as aphids, red spiders and shell insects should be prevented. Spray 3 to 4 times a year, the first before anthesis, the second after anthesis, and the third from July to August.

If the cherry blossom seed is not properly maintained after sowing, it will not only cause diseases and insect pests of cherry blossom seedlings, but also cause it not to germinate or die in the budding stage, so we must pay more attention to it.
