1. Planting regional environment: it can be planted in the south, and cold-tolerant varieties can also be planted in the Yellow River basin, but indoor potted plants should be used for wintering in cold areas in the north. It can be planted after defoliation and before germination in spring. In order to improve the survival rate, we should avoid damaging the root system and transplant with soil balls. The ground should be planted in the leeward and sunny places. Potted soil with 3 parts humus soil, 3 parts garden soil, 2 parts river sand and 2 parts decomposed fertilizer was selected. Watering after planting 1 time. Keep it in a cool place, and move it to the sun for normal management after the growth resumes.

Light and temperature: I like warm and sufficient light. Except for apricot varieties, it is generally resistant to-10℃ except -25℃. High temperature resistance, can grow at 40℃. It grows best in the area with annual average temperature 16-23℃. Very sensitive to temperature, it blooms when the average temperature reaches -5-7℃ in early spring. If it encounters low temperature, the flowering period will be delayed, and if it encounters low temperature, the flowering period can be extended. The growing season should be placed in a sunny and well-ventilated place. If it is in a cool environment with insufficient light, it will grow thin and bloom sparsely. Don't enter the room too early in winter, and it is advisable to1late October 165438+ to enter the room so that the flower buds can differentiate through the vernalization stage. In winter, it should be placed in a sunny place indoors and the temperature should be kept at about 5℃.

3. Watering and fertilization: Pay attention to watering during the growth period. The soil in the basin should always be moist, and it should not accumulate water, be too wet or too dry. It is necessary to master the principle of watering. Generally speaking, water less when the temperature is low on cloudy days, or water more. You can water it twice a day in summer, once a day/kloc-0 in spring and autumn, and dry it thoroughly in winter. Fertilization is also reasonable. Apply base fertilizer before planting and add a small amount of potassium dihydrogen phosphate at the same time. Apply potassium dihydrogen phosphate 1 time before flowering, and apply cake fertilizer 1 time before flowering to supplement nutrition. In June, 1 times compound fertilizer can be applied to promote flower bud differentiation. After defoliation in autumn, apply organic fertilizer 1 times, such as decomposed manure.

4. Pruning: Pruning time of ground-planted plum blossoms can be carried out within 20 days after flowering. Give priority to with natural tree, cut off cross branches, erect branches, dead branches, too dense branches, etc. And cut short the side branches to promote the flowers to bloom. After potted plum blossoms are put into pots, they should be cut again to lay the foundation for bonsai. Plum piles are usually used as scenery to graft plum blossoms in various postures. Keep a certain temperature, and you can see plum blossoms in full bloom during the Spring Festival. If you want to blossom on May 1, you need to keep the temperature of 0-5℃ and the humid environment. Move out in early April and keep it in a sunny and well-ventilated place, so that you can see the flowers around May 1.

5. Flowering control: potted plum blossoms are generally for family viewing. After defoliation in winter, keep the indoor temperature at 0-5℃, gradually raise the temperature to 5-10℃ after New Year's Day, fully receive sunlight every day, and often spray water on the branches, and the humidity of the water should be close to room temperature.

6. Artificial cultivation

Grafting is commonly used in reproduction, and the rootstocks are mostly plum, peach, apricot, wild apricot and wild peach. Plum blossoms should be cultivated in the open space on sunny or semi-sunny slopes with a spacing of 3 ~ 5m. Usually in the growing period, that is, from autumn to early winter, fertilizer is applied three times, such as cake fertilizer compost, manure and so on. Apply quick-acting fertilizer before budding; After the new shoots stop growing (from the end of June to the beginning of July), appropriate water control and fertilization are applied to promote flower bud differentiation. Plum blossoms are suitable for bonsai cultivation. Put the plants that have been cultivated in the field for several years in a flowerpot. Pot soil should be soft, loose and fertile, and it should be trimmed before and after planting.
