Maintenance method

In terms of lighting, plum blossoms like sunny environment, and they should also pay attention to avoiding strong direct sunlight in summer to ensure enough scattered light. In terms of watering, plum blossom is a woody plant, but its water demand in the growing period is also very large.

At the same time, we should also pay attention not to let the basin soil accumulate water, which will cause harm to the root system. Water every day in summer, and replenish water frequently in spring to keep the soil moist. Plum blossoms grow slowly in winter, which can keep the pot soil slightly dry.

4. Knowledge of plum blossom growth process

Meixi has a warm climate, and its flowering period is particularly sensitive to climate change. Meixi has a high air humidity, but it avoids heavy rain during flowering. Plum blossoms can grow well in areas where the annual rainfall is above 1000mm, and the requirements for soil are not strict and relatively poor. Active tree species, like sunshine and good ventilation. It is a long-lived tree species. The flowering period in the Yangtze River basin is from February to March.

Flowers solitary or sometimes two peanuts in 1 bud, 2-2.5 cm in diameter, with strong fragrance, opening first and then leaves; Calyx is usually reddish brown, but some varieties of calyx are green or green purple; Petals obovate, white to pink.

Flowers can be refined, and flowers, leaves, roots and seeds can be used as medicine.

The fruit can be eaten, salted or processed into Senecio scandens, or smoked into ebony, which has the effects of relieving cough, stopping diarrhea, promoting fluid production and quenching thirst. Plum blossom can resist the harm of root-knot nematodes and can be used as the rootstock of drupe fruit trees.

Plum blossom is the first of the top ten famous flowers in China. Together with orchids, bamboos and chrysanthemums, they are called "four gentlemen", and together with loose bamboo, they are called "three friends in cold years". In the traditional culture of China, Mei gives people an incentive to work hard with her noble, strong and modest personality. In the cold, before the flowers bloom, the world is lonely, and spring has come.

Plum blossoms are mainly grafted, and sowing is also acceptable. Grafting is always done by cutting or budding. The rootstock should be the seedling plum. Cuttings can be carried out in the early spring, or in winter, cutting or splitting can be carried out indoors, and rootstock seedlings are bare and have no soil.

Bud grafting is mostly carried out from June to September, and shield-shaped bud grafting is often used. 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. If the old trunks of plum are butted, potted stumps can be formed quickly. Plum blossoms are suitable for bonsai cultivation.

Put the plants that have been cultivated in the ground for several years in a flowerpot. Pot soil should be soft, loose and fertile, and it should be trimmed before and after planting. Common diseases include perforation, anthracnose, powdery mildew, dead branch gummosis, dry rot gummosis and so on. Pay attention to avoid using dimethoate when using insecticide, because dimethoate is easy to control the pharmacognostic harm of plum blossom and lead to defoliation.

Love cool and hate hot, suitable for dry and wet. I can tolerate the low temperature of -30℃ and grow normally in areas with an annual average relative humidity of about 45%. Like light, but also a little tolerant of shade.

Loose, fertile and well-drained neutral loam or sandy loam is required, and it is forbidden to stick heavy soil or plant at low temperature. The flowering period is April-May.

Grafting is often used for cultivation, because it belongs to Paeonia genus with Paeonia lactiflora, and Paeonia lactiflora is often used as rootstock. Morphological characteristics: the root system is fleshy, with few branches and few fibrous roots. Plant height 1-3m, the old stems are grayish brown and the branches are yellowish brown.

Bipinnate compound leaves, alternate. Flowers are solitary at the top of stem, with flower diameter 10-30cm. The colors are white, yellow, pink, red, purple and multicolor, and there are single flowers, compound flowers, double flowers and cabinet flowers.

There are many ways to divide the tip of peony, which can be divided into upright type, flat type and semi-open type according to plant type. According to the bud type, it can be divided into round bud type, narrow bud type, olecranon type and exposed mouth type; According to the branching habit, it can be divided into single branch type and cluster branch type; According to the color, it can be divided into white, * * *, pink, red, purple, blue, black and many colors (actually there is no pure blue and black); According to the flowering period, it can be divided into early flower type, middle flower type, late flower type and autumn and winter type (some varieties have the habit of secondary flowering, which can naturally reopen after flowering in spring and autumn and winter, called autumn and winter type); According to the pattern, it can be divided into four levels: department, class and group.

Propagation and cultivation: propagation by branching and grafting, as well as sowing and cutting. The suitable period of transplantation is from late September of 10 to early October of 10, neither too early nor too late.

If you like fertilizer, you should fertilize it at least three times a year, namely "flower fertilizer", "bud fertilizer" and "winter fertilizer". Pruning should be carried out after 2-3 years of cultivation.

For varieties with vigorous growth and strong branching ability, it is only necessary to cut off the weak branches, keep all the strong branches, and remove the new buds at the base in time to maintain a beautiful plant shape. Bud removal is also an extremely important job. In order to make plants produce bright flowers and keep plants strong, the number of flowers should be controlled according to the age of trees.

In the early stage of budding, a certain number of fully developed flower buds should be selected, and excessive flower buds and weak buds should be removed as soon as possible. Generally, 5-6 year-old plants keep 3-5 flower buds.

For newly planted plants, all flower buds should be removed in the following spring to prevent them from blooming, so as to concentrate nutrition and promote plant development. Common diseases are brown spot, red spot and rust. Common pests are nematodes, grubs and cutworms.

It is also suitable for arranging flower borders, flower beds, flower belts and potted plants, and the application is more flexible. By delaying flowering, flowers can bloom all year round. The root bark is used as medicine, and the petals can make wine.

After peony changed from wild species to domestic species, due to the change of environmental conditions and continuous artificial breeding and cultivation, not only the color, pattern and flowering period changed sooner or later, but also the plant shape, root length, thickness, leaf color and shape changed. 1. Plant type Due to different varieties, peony plants are different in height, clustered, straight and scattered.

Generally speaking, according to its shape or divided into five types; 1. The upright branches are tall and upright, with compact distribution and small spreading angle, and the included angle between the branches and the vertical line is mostly 30? Inside. Internodes are long, the annual growth of new branches is 10~ 15 cm, and the average plant height of five-year-old trees is 40~50 cm, the highest exceeding1m.
