(1) Morphology, variety and ornamental characteristics Wild Rosa, also known as Rosa multiflora, is a deciduous or semi-evergreen creeping shrub of Rosa in Rosaceae. The flowering period is from May to September, and it is open for half a year. There are many varieties and complicated names. According to Qunfangpu, the varieties of roses are:

(1) Pink rose, single petal, several or several flowers clustered into a flat corymb;

(2) Seven Sisters (ten sister flowers) has large leaves and double petals, and often six or seven flowers are combined into flat umbels;

(3) Lotus rose, double, light pink, lotus-shaped;

In addition, Huang Qiangwei is not only brightly colored, but also has an early flowering period, which is cherished by the horticultural sector.

It is also said that there are three kinds of roses: perfume rose, red branch rose and light leaf rose. In fact, there are more kinds, varieties and varieties of roses than mentioned above, and the names of different places are also inconsistent. What we usually call roses is just a generic term for this kind of flower. There are many colors, such as milky white, goose yellow, golden yellow, pink, red and purple black. There are large and small flowers, double petals and single petals, but they are all clustered at the top of the tree, with bright colors and fragrant smells. They are ornamental flowers with both color and fragrance. Branches are semi-climbing, and various forms can be attached according to the framework. Should be arranged in flower racks, flower grids, iron gates, flower walls, etc. Hundreds of flowers are in full bloom in summer, and there is indeed a scenery of "dense branches and leaves and flowers". It can also be made into small shrubs and cultivated as potted flowers. Some varieties can be cultivated as cut flowers.

(2) Origin, Ecological Characteristics and Management Rosa is native to the south-central provinces of China. Wild roses are naturally distributed in streams, roadsides, gardens, corners and other places, often densely clustered and leafy. After light rain or morning dew, the petals are red and soaked, and the scenery is quite beautiful. The adaptability is quite wide, and it is suitable for planting in vast areas of southern China except in severe cold and winter. Roses are flowers and trees that like light, so they need plenty of sunshine. Suitable for fertile and humid land with good drainage. There are few pests and diseases of wild roses, and insect pests such as sawflies, scale insects, aphids, scorched leaves, canker and black spot often occur in artificial cultivation. In addition to spraying with chemicals, the scenery should be used in coordination with other flowers and trees, and it is not advisable to plant too much in one place. Every winter, pruning old branches and dense branches frequently, keeping light and good ventilation can reduce pests and diseases. Pruning is an indispensable and important process in rose landscaping. If the pruning is not good, it will grow into a pile of thorns and be uneven, which will not only cause many diseases and pests, but also be unsightly. The longer plants grow, the more flowers they bloom, and the more nutrients they need. Every winter, it is necessary to fertilize the soil 1 time to keep the shoots and buds lush and beautiful. Cultivate potted flowers and pay more attention to pruning and shaping. Because of the large flower yield, cut flowers need to be fertilized 1~2 times a week in flower season. Pay attention to cultivating mother branches and cutting off buds on weak branches.

(3) The seeds of propagation technology can be used for seedling raising, but cuttings of the same year are often used for seedling raising in production, which is easy to survive. Rare varieties are not easy to cut, and can be propagated by layering or grafting. Asexual seedlings can bloom in the same year. For the seedlings used as potted flowers, the older branches of fine varieties should be selected, and the seedlings should be raised by layering method, and the main buds should be trimmed and artificially dwarfed. For seedlings used as cut flowers, we should choose varieties that can form mother branches and have large and bright flowers.

Similarly, the fifth song of Elva Hsiao's second record "Red Rose" is also called Rose.

Rose-Elva Hsiao-Red Rose

Rosa Elva Hsiao

Word: Qu: Sakura Editor: Chen Wei

I don't know who didn't sleep last night and woke up the red rose.

It will be so brilliant in a short time, and it will definitely bloom overnight.

Is it missing someone? Can it feel my tears?

I will be heartbroken and bright red at the thought of you, like blood from an old wound in my heart.

Oh ~ ~ I want to see you again.

Let me know that you also feel that our love has not been in vain.

Until the last night of my life

You and I still miss and remember you deeply, and I love you deeply.

My heart is full of twists and turns.

Oh ~ ~ Baby, I want to kiss you again and love you again.

Our love was not in vain.

Maybe I'll miss it ~ ~

You know what I want.

This is the last time ... Oh

Oh, baby! I want to go back to my life ~ ~

You know how much I need you.

My memory is unforgettable.

The names of roses are wall, thorn rose and mountain thorn. Flowers are called white flowers. Because its vines are soft and weak, they are born by climbing against the wall, hence the name "weak wall". Its prickly stems are mostly born between Shan Ye, hence the name "Rosa roxburghii" or "Rosa roxburghii". Flowers are called "white flowers" because they can no longer bloom in spring and are white. This fruit is named "Shi Ying" because it gathers together like stars.

Planting and cultivation

Rosa belongs to Rosaceae. Deciduous shrub or vine with slender vines and hooked thorns. Therefore, in "Red Rose", Zhuang Nanjie has poems such as "deep red short thorn hook spring scenery", and Lu Guimeng has poems such as "including stabbing people". Odd pinnate compound leaves, elliptic or obovate leaflets, usually arranged in 5-7 pieces, with serrated leaves. It blooms in late spring and early summer, with white, pink, bright red and fragrant corymbose inflorescences, and often 7- 10 flowers are clustered together, so it is also called Seven Sisters or Ten Sisters, which is different from single petals and double petals.

Pedicels have short glandular hairs, the flowers bear fruit, and the fruits are spherical, with many clusters, green at birth and purple at maturity, which is very beautiful. There are white hairs in the nucleus, like the nucleus of Rosa laevigata, with many seeds.

Roses propagate through seeds, ramets, cuttings, grafting and layering. Seed propagation needs sand storage and sowing in spring. Plant division is simple, easy to survive and fast to grow, which can be carried out in both spring and autumn, preferably before germination in early spring. Cutting, you can take strong and disease-free hard branches from the mother plant in early spring, with 3-5 buds.

A paragraph. Cutting is also easy to survive. For layering, in spring, you can choose strong branches on the mother plant that are low from the ground, cultivate and bury the soil in sections, and carve a piece of skin with a knife in each section to promote scabbing and rooting. After it is found to take root, the mother plant can be gradually cut off to make it a new plant.

Roses, like sunlight and moisture, are suitable for fertile soil, but they are also resistant to shade and cold, and can grow on barren land. Developed root system, strong vitality and strong disease resistance. Rose is an excellent rootstock for grafting fine varieties of rose and Chinese rose.

Rose is prone to powdery mildew and soot disease if it is not ventilated at high temperature, so attention should be paid to prevention and control.
