Propagation methods and Culture points for attention of Rose Flower

Rose is one of the world's famous ornamental plants. It has a long history of cultivation in China. As far back as 1630, Wang Xiangjin wrote "Group Fragrance Spectrum," Chen Haizi wrote "Secret Flower Mirror" in 1688, and Wang Hao wrote "Guang Group Fragrance Spectrum" in 1708. There are records of rose, rose and banksia rose. Let's take a look at the cultivation methods and precautions of rose together!

Rose flower propagation method

Rose flower seed can be used for seedling, but in production, shoot cuttings are often used in that year, which is easy to survive. Rare varieties are difficult to cut, available layering or grafting method of propagation, asexual propagation of seedlings, that year can flower. For potted plants, older branches of superior varieties should be selected, seedlings should be raised by layering method, and attention should be paid to pruning main buds and artificial dwarfing. As cut flower seedlings, we should select varieties that can form flower picking mother branches and have large and colorful flowers. Rose can also be used in tissue culture, hydroponics, grafting, plant and other methods of propagation.

Rose flower cultivation method

1, soil: rose flower on the soil requirements are not strict, drought resistance, barren resistance, cultivation in the soil layer deep, loose, fertile and moist and smooth drainage of the most suitable growth, but also in the clay heavy soil normal growth. Whether it is planted in the ground or potted, the cultivation soil of rose flowers should be fully decomposed sandy soil for the best.

2, light: rose flowers are light-loving flowers, prefer adequate sunlight, but also resistant to semi-shade, cold-resistant, very strong adaptability, in addition to winter cold overwintering, all parts of the south are suitable for planting. Rose growth period should ensure that there is sufficient sunlight, in order to be able to flourish, more flowers.

3, watering: rose flowers like wet, afraid of wet avoid waterlogging. From rose bud to blossom before, can be appropriate to irrigate some water, to soil moist but not ponding for the best, wait until rose blossom, should reduce the amount of watering, watering soil to see dry see wet, in rainy season should pay attention to drainage waterlogging, so as not to rot roots ponding.

4, fertilization: roses are more fertile, but also tolerant of barren, March can be applied once to twice nitrogen-based liquid fertilizer, to promote rose branches and leaves luxuriant, April and May can be applied twice to three times to phosphorus potassium-based fertilizer, to promote roses can be more pregnant buds and more flowers, after flowering and then apply a rejuvenating fertilizer, and then you can stop fertilization. Rose flowers need to be cultivated and fertilized once a year in winter.

5, pruning: pruning is an essential process in most flower farming, natural roses are no exception, especially for potted flowers, more attention should be paid to pruning. Generally, the roses of adult plants are pruned once a year before sprouting in spring, and the amount should be moderate to ensure that the rose branches are moderately dense and beautiful in appearance. The old branches and dense branches of roses should be pruned frequently every winter to keep light and ventilation good, which can reduce pests and diseases.

Rose Notes

1. Rose anthracnose

[Symptoms] The lesion occurs at the leaf margin, semicircular, dark brown at the edge of the lesion, brown to light brown in the middle, and black small dots on the late lesion. The pathogen overwinters on diseased leaves. Under warm and humid conditions, spores germinate and damage leaves. Plant cluster too dense, moisture retention time is long, easy to disease. Anthracnose occurs sporadically, and can be treated simultaneously in the control of black spot and leaf spot.

[Prevention and control] Clear the garden in time at the end of autumn and early winter, collect the diseased leaves and burn them in a centralized manner. Strengthen maintenance, proper pruning, thinning of over-dense branches, so that good ventilation and light transmission. If necessary, spray 20% Longkejun (Thiazole copper) suspension 500 times or 78% Cobo (wave). Manganese zinc) WP 600 times solution, 75% Daconine (Chlorothalonil) WP 600 times solution, 50% Shibao Gong or Shibaike (Prochloraz) WP 1000 times solution, 25% Cartraline WP 500 times solution.

2. Rose powdery mildew

[Symptoms] Leaves, petioles, tender shoots and buds can be affected. Irregular white powdery mildew spots are produced on adult leaves, and the diseased leaves gradually turn brown from the tip or edge of the leaves, causing the whole leaves to dry and fall off. Young leaves infected, green spread, gradually expanded, the edge is not obvious, young leaves on both sides of white pink spots, after covering the whole leaf, leaves become pale gray or purple. The new leaves are deformed. Petiole, new shoots infected after internode shortening, stem thinning, some of the disease appeared dry shoots, disease is also covered with white powder. The flower buds are infected, the flower buds and flower pedicels are covered with white powder, the calyx, petals and flower pedicels are deformed, and the severe ones shrivel and die, losing their ornamental value. Powdery mildew overwinters on diseased buds. Planting too dense, too much nitrogen, poor ventilation, insufficient sunlight, easy to disease.

[Control] Select powdery mildew resistant varieties. When pruning in winter, pay attention to cutting off diseased branches and buds. During disease onset period, less nitrogen fertilizer and more phosphorus and potassium fertilizer were applied to improve disease resistance. Pay attention to ventilation and light transmission, timely drainage after rain, prevent moisture retention, can reduce the incidence. At the early stage of disease, spray 20% triadimefon EC 1000 times or 20% triadimefon sulfur suspension 1000 times, 50% carbendazim WP 800 times. If resistance to the above fungicides occurs, 12.5% myclobutanil EC or 30% tefulin WP 3000 times solution can be sprayed instead. Before budding in early spring, spray 40~50 times solution of 2~3 degree stone sulfur mixture or 45% crystal stone sulfur mixture to kill overwintering bacteria.

3. Rose beetle

[Characteristics] Rose beetle mainly damages roots, leaves, buds and other parts, seriously affecting flower yield and quality.

[Control] Light trapping, willow trapping, oscillation killing, etc. When the damage is serious, 2.5% deltamethrin 2000~3000 times or 50% phoxim 1000~1500 times can be sprayed. The effect is better, but must not be sprayed in flowering.

Rose cultivation methods and precautions

Roses need sunlight to grow.

Rose flowers are light-loving flowers and trees, grow well in sunny environments, attractive colors. During the growth period do not need shade, the stronger the better, not afraid of no sunlight, afraid of insufficient sunlight.

Roses need water to grow.

Rose love wet fear, from germination to flowering, can be appropriate to pour a little more water, ensure that the soil surface wet but not waterlogging. After flowering do not water too much, see dry soil see wet, rain can be appropriate, but to timely drainage.

The way of watering should also pay attention to, do not water from the beginning during flowering, especially when the sun is strong, do not let the leaves and flowers accumulate water, so as not to burn the flowers and leaves.

Roses need nutrients to grow.

Roses love fat, but also poor tolerance, whether full or not can grow. The usual fertilization methods are:

Fertilization 1~2 times in March, mainly nitrogen-containing liquid fertilizer, to promote the growth of branches and leaves. Apply fertilizer 2~3 times in April ~ May, mainly phosphorus and potassium fertilizer, promote the flowering of pregnant buds; apply compound fertilizer once after flowering, promote the recovery of plants.

In addition to this time, try not to fertilize, so as not to affect the flowering of plants too much fertilizer.

Roses grow against pests.

Rose flowers are delicate, but also weak, often infected with many diseases. Most of them are fungal diseases, timely spraying Bordeaux mixture or methyl thiophane solution when the disease occurs, and the use of chemical prosthesis at home, the effect is better. At ordinary times, attention should be paid to enhancing the disease resistance of rose flowers, and phosphorus and potassium fertilizers should be added when fertilizing.

Rose farming needs attention.

Rose bud ability is very strong, luxuriant growth, be sure to prune in time. After flowering, they should also be pruned in time to ensure the illumination and ventilation of the branches.

Culture method of rose flower

Cultivation: planting, planting should be ditched before the application of base fertilizer. Water regularly in spring. Each year new long shoots grow from the roots and flower on their lateral branches that year. After flowering, cut off the flowering branches. Rosa multiflora is very cold-resistant fertilizer, growth process, rainy season to pay attention to drainage and waterlogging, fertilization should be 2-3 times, to promote the flowering of flowers in the next year.

Propagation: commonly used ramets, cuttings and layering propagation, spring, early summer and early autumn can be carried out. It can also be sown in autumn or spring after sand storage, and germinate 1-2 months after sowing.

Sunlight: roses are light-loving flowers and trees, which require sufficient sunlight to maintain sufficient sunlight during growth.

Fertilization: Rose flowers like fertilizer, but also tolerant of barren, March can be applied 1 to 2 times to nitrogen-based liquid fertilizer, promote the growth of branches and leaves, April, May 2 to 3 times to phosphorus potassium-based fertilizer, promote its multiple pregnant buds and flowers, after flowering and then apply a rejuvenation fertilizer can no longer apply fertilizer.

Rose cultivation methods and precautions to teach you how to raise roses

Watering: Rose likes to moisten but afraid of wet and avoid waterlogging. From germination to flowering, water can be poured more appropriately. It is necessary to moisten the soil without waterlogging. After flowering, water should not be too much. The soil should be dry and wet. Pay attention to drainage and waterlogging prevention in rainy season.

Pruning: rose budding strong, lush growth, such as not timely pruning, in the sultry, humid, insufficient light, poor ventilation conditions, prone to pests, so after flowering to a pruning.

precautions

Rose flowers in rainy, humid, poor ventilation, poor sunshine conditions, rose susceptible to powdery mildew, once found to cut off the diseased branches destroyed to avoid infection, and spray low concentrations of stone sulfur mixture or bordeaux solution, topozin solution to prevent the spread of disease.

Diseases and insect pests: roses can be infected with many diseases, most of which are caused by fungi. Before the disease occurs, spray 200 times of Bordeaux mixture to prevent it. Spray 15% triadimefon WP 1000 times or 70% thiophane methyl WP 1000 times. Insect pests are harmful to aphids and sting moths. Spray with 10% insecticide 2000 times.
