Latin scientific name: Prunus persiacabatsch.var.duplex rehd.

Alias: Pink Bitao, Chiba Peach, Flower Peach

Family and genus: Rosaceae, Prunus.

is a variety of peach.

It is also the general name of double-petal flower-viewing peach (many varieties, such as sprinkling golden peach and white peach).

Compendium of Materia Medica: "There are many peaches ... in fact, there are hearts, peaches, peaches, peaches, peaches, peaches, peaches, peaches, peaches, peaches, peaches, peaches, peaches, peaches".

Morphological characteristics:

Small deciduous trees, up to 8 meters high, usually controlled at 3-4 meters after shaping, with reddish brown branchlets and no hair; Leaves elliptic-lanceolate, 7-15 cm long, apex acuminate. Flowers solitary or two in leaf axils, double pink. Other varieties are white, crimson, sprinkled with gold (variegated) and so on.

propagation and cultivation:

in order to maintain good quality, it is necessary to propagate by grafting, and the rootstock is Prunus mume. The survival rate of grafting can reach more than 9% by using summer bud grafting technology. The specific operations are as follows:

1. Scion selection. The mother tree of Peach should be robust without pests and diseases, and the plants with excellent flowers and fruits should be selected as scions.

2. Grafting method. In summer, bud grafting can cut off buds, or take less xylem buds and peel them at the stem of rootstock. Cutting the scion of the mother tree means cutting off the leaves and leaving the petiole. Cut upward with a knife tip 1 cm below the scion bud, the length is 1.5-2 cm, and the inside of the bud should be slightly xylem. The rootstock with the bud in the middle of the scion bud can be a seedling as thick as a pencil, and the stem is 3-5 cm away from the ground. The vertical part on the north side of the trunk is selected. The first knife is slightly xylem, and the cut bark is cut off by 1/2-2/3. Insert the scion bud into the rootstock to form a layer. Wrap the plastic tape under the grafted bud for 2 times to the left, and then wrap it for 2 times to the right, and tie it up evenly, so that it can prevent the bud from drying and combine firmly to expose the grafted bud. Pay attention to the budding time, the best time is from June to mid-July in the south and from July to mid-August in the north.

3, after management. 1-15 days after bud grafting, the petiole falls off in yellow, which is a symbol of survival, while the petiole turns black, which means it is not alive. After the surviving seedlings grow new buds and heal completely, remove the plastic adhesive tape, and cut the rootstock at the place 1 cm above the bud joint. After germination, remove the rootstock and germinate. At the same time, combined with fertilization, generally apply compound fertilizer for 1-2 times to promote the lignification of the new shoots of the scion, which has cold resistance. In order to control aphids, 2, times dimethoate solution is sprayed, and when leaf shrinkage occurs, a mixture of stone and sulfur can be used.

ecological habits:

like light, drought-resistant, requiring fertile soil and good drainage. The growth period requires strengthening management, fertilization, irrigation, weeding and pest control. Cold tolerance is not as good as peach.

Garden use:

Peach blossoms are colorful, enchanting and charming, which are suitable for lakeside, stream, roadside and park layout, small courtyard decoration and potted plant viewing, and are also commonly used for cutting flowers and making bonsai. There are also common weeping peaches.

Distribution of origin:

It is native to China and distributed in northwest, north, east and southwest China. Now all countries in the world have introduced and cultivated.

the flower is double and pink. Drupe is spherical with short hairs on the skin. Flowering from April to May

"On the duchang county of Poyang Lake, there are 1, lighted towers, but people in Nanshan are separated by water, and the east wind blows the old peach blossom"

Tung tree is the local name of some trees. In some areas, Tung tree refers to Paulownia (such as the Yellow River Basin), in others it refers to Tung tree, and in others it refers to Indus. As for the French phoenix tree (Platanus acerifolia), it is generally referred to as phoenix tree for short, not tung tree.

1。 Indus: Platanus acerifolia. Deciduous trees, up to 35 meters high; Broad crown; The bark is grayish green, with irregular flaking. Leaf blade palmate, with irregular sharp teeth and wavy teeth at the edge. Spherical inflorescences are usually two in a string, shaped like hanging bells, so they are called Platanus acerifolia. As early as the reign of Tongzhi in Qing Dynasty, Platanus acerifolia was planted in Shanghai. The buttonwood tree is tall, luxuriant in branches and leaves, fast growing, easy to survive and resistant to pruning, so it is widely planted as a street greening tree species and has the reputation of "the king of street trees".

Indus belongs to Platanus in plant taxonomy. There is only one genus under the family, namely Platanus, and there are about 7 species under it, which are native to Southeast Europe, India and America. However, only three species have been introduced and cultivated in China, namely Platanus ×acerifolia, also known as Pterocarya, and Platanus occidentalis, the parent of this hybrid, also known as Meitong and Platanus orientalis, also known as Fatong. Now we usually refer to these three species as "Fatong".

2。 Tung tree or Tung oil tree, also known as Three-year Tung and Five-year Tung, scientific name: Aluerites fordii Hemsi. Flowering period: April to July. It is a deciduous tree, with a slender tree shape up to 1 meters. It belongs to the genus Tung Tree of Euphorbiaceae, with a horizontally spreading crown and dense branches and leaves. It is a good landscape tree and street tree species. Its bark is smooth and gray. Monoecious flowers with 5 petals, 8-1 stamens in the male flowers and 3-5 seeds in the fruit.

Tung oil tree is a unique economic forest tree species in China and one of the four woody oil tree species, with a history of more than a thousand years and cultivation.

there are six kinds of tung trees planted in the world, among which the three-year-old tung trees and tung trees originated in China are the most common. The oil squeezed from tung oil seeds is called tung oil, and the oil squeezed from tung oil seeds is called wood oil, which is slightly inferior to tung oil in quality. Tung oil and wood oil are golden or yellow in color, both of which are excellent drying oil and shiny. Tung oil is a good industrial oil. They are impervious to water, air, electricity, acid and alkali, corrosion and cold and heat, so they are widely used in paint, plastics, electrical appliances, artificial rubber, artificial leather and tung oil, which are traditional export commodities in China, accounting for 7% of the world's total output.

3。 Paulownia fortunei: Paulownia fortunei

alias paulownia

belongs to Scrophulariaceae and paulownia

. It is a deciduous tree with a height of 2m and a sparse and oblate crown. The leaves are ovoid or broadly ovoid, 15-3cm long and 1-2cm wide, the apex is acuminate, the base is heart-shaped or nearly round, the whole or 3-lobed, and the back of the leaves is densely covered with gray-white dendritic hairs; The petiole is 1-18cm long. Panicle is about 3cm long, calyx is 1.6-2cm long, and it is lobed to 1/3; Corolla funnel-shaped, bell-shaped, purple, 7-9.5cm long, with glandular hairs or stellate hairs on the outside of corolla tube, but hairless and purple spots on the inside.

There are also several related species
