Can the rose flowers be hydroponically cultured? the methods and precautions of hydroponic culture of rose flowers / can not grow up

As a good product for family farming, roses are often raised in the yard because of their large size. But many flower friends want to keep it indoors, what to do at this time? Many people think of hydroponics. Can the roses be hydroponically cultivated? It is understood that the rose flower vitality is extremely tenacious, and the resistance is also very strong, so it can be hydroponic culture. As for the method of hydroponic culture of rose flowers, it is believed that the introduction will be made by the editor.

Can roses be hydroponically cultivated? yes.

Because in the wild roadside can grow, the vitality of the rose is very strong, so the rose can be hydroponic, of course. However, we should pay attention to that roses can be hydroponic, but not hydroponic for a long time! Flower friends can try hydroponic rooting and turn to soil culture when the root grows to about 3 centimeters.

If you want to see the rose blossom in water, you may be disappointed, because the lack of nutrition in the water, it is difficult to support until the rose blossoms, even if it does blossom, it is not beautiful. Of course, when the early rose did not blossom, it was also possible to view the leaves by hydroponics. After all, the tender green leaves were also very beautiful.

II. Methods and matters needing attention of hydroponic culture of rose flowers

Tools: plastic bottles, scissors, cardboard

If you want to cultivate roses in water, you must first prepare water and bottles, and then select cuttings. The specific operation methods are as follows:

1. Selection of water

Hydroponic rose water, do not directly choose tap water in the pipe, you can use overnight water, or cool plain boiled water.

2. Container selection

Before hydroponic culture, prepare the container for Qiang Wei Hua. A simple plastic bottle is fine, and you can choose a beautiful glass bottle if you want to see it.

3. Cuttings selection

The most important thing in the hydroponic culture of a plant is the selection of cuttings. Good cuttings represent half of the success of hydroponics. We first cut the branches of the roses and choose the semi-lignified green branches with budding eyes. Then make a simple pruning of the branches, leaving 2 or 3 leaves.

4. Hydroponic culture begins

Put the prepared cuttings in the bottle, as pictured above, the bottle of this tea drink is still good. In order to take root, the editor prepared a piece of cardboard, poked several holes, and inserted the cuttings into the water from the hole.

After the above work, the hydroponic culture of roses is basically completed. At this time, we say that the bottle can take root in about a month and a half when it is put in the sun. After it takes root, everyone can cultivate it in the soil. After that, how to raise roses is introduced in detail in the breeding methods of roses, so I won't say much here.

5. Matters needing attention in hydroponic culture of rose flowers

Change water: before roses take root, change water once every 3-4 days, change water less after rooting, and add water in time after water evaporation. Check whether the water is spoiled. If the water smells rotten, check whether the root is rotten. If the rotten part is cleaned up in time, it will take root again.

Can roses be hydroponically cultivated?

Roses can be hydroponic, but not long-term hydroponic, we can try hydroponic rooting, when the root grows to about 3 centimeters after the conversion to soil culture. Of course, the early rose did not blossom, can be hydroponic observation of the leaves, green leaves are also quite beautiful. After the conversion to soil culture, the lack of nutrition in the water is difficult to support the rose blossom.

How to cultivate Rose in Water

The following editor introduces a simple method for you. Tools can simplify anything.

First of all, cut the branches of the roses and choose the semi-lignified green branches with bud eyes.

Then make a simple pruning of the branches, leaving 2 or 3 leaves.

Casually insert the branches into the bottle to see that the bottle of this tea drink is not bad.

Ok, put the branches in the sun and they will take root in about a month and a half.

Change water 3-4 days before rooting, change water less after rooting, and add water in time after water evaporation. Do not directly choose tap water in the pipe, you can use overnight water, or cool plain boiled water.

Check whether the water is spoiled. If the water smells rotten, check whether the root is rotten. If the rotten part is cleaned up in time, it will take root again.

Do not apply fertilizer too often, too much fertilizer will burn the roots, there will also be yellow leaves, you can put a rusty screw in the water to replenish the iron.

Propagation methods and Culture points for attention of Rose Flower

Rose is one of the most famous ornamental plants in the world, and it has a long history of cultivation in China. As far back as 1630 when Wang Xiang Jin wrote "Qunfang Spectrum", Chen Yuanzi wrote "Secret Flower Mirror" in 1688, and Wang Hao wrote "wide Group Flower Spectrum" in 1708, there have been records of roses, roses, roses and woody flowers. let's take a look at the rose culture methods and matters needing attention.

Propagation method of rose flower

Rose seed can be used for raising seedlings, but it is easy to survive by using tender wood cuttings in the same year in production. Valuable varieties are difficult to cut and can be propagated by pressing or grafting. Seedlings of asexual reproduction can blossom in the same year. For the seedlings used as potted flowers, the older branches of fine varieties should be selected, the seedlings should be raised by striping method, and attention should be paid to pruning the main buds and artificial dwarfing. For seedlings used as cut flowers, varieties that can form mother branches and colorful flowers should be selected to raise seedlings. Roses can also be propagated by tissue culture, water culture, grafting, plantlet and so on.

Culture method of rose flower

1. Soil: the rose flower is not strict in soil, resistant to drought and barren. It is most suitable to grow in deep, loose, fertile, moist and well-drained soil, and it can also grow normally in clayey soil. Whether planted in the ground or potted, the cultivation soil of rose flowers should be fully mature sandy soil as the best.

2. Illumination: the rose is a light-loving flower, which likes plenty of sunshine, and it is also resistant to semi-shade, cold and adaptability. it is suitable to be planted in all parts of the south except for the severe cold in winter. Roses should have enough sunshine during their growth so that they can flourish and blossom more.

3. Watering: roses like to be wet, afraid of being wet and avoid waterlogging. From the rose sprouting to blooming, you can properly irrigate some more water, with the soil moist but without stagnant water as the best. After the rose blossoms, you should reduce the amount of water, dry and wet the soil when watering, and pay attention to drainage and waterlogging in the rainy season to avoid stagnant water rotting the roots.

4. Fertilization: roses prefer fertilizer and are resistant to barren. Liquid fertilizer dominated by nitrogen can be applied once or twice in March to promote the branches and leaves of roses to flourish. In April and May, fertilizers mainly based on phosphorus and potassium can be applied 2 to 3 times. In order to promote the rose flower to have more pregnant buds and blossom, and then apply rehabilitation fertilizer again after flowering, then you can stop fertilization. Roses need to cultivate soil and fertilize once a year in winter.

5. Pruning: pruning and shaping is an indispensable process in most flower breeding, and natural roses are no exception, especially when cultivated as potted flowers, we should pay more attention to pruning and shaping. In general, adult roses are pruned before germination every spring, and the amount should be moderate to ensure that the branches of the roses are dense and beautiful. The old branches and dense branches of roses should be often trimmed every winter to maintain good light transmission and ventilation so as to reduce diseases and insect pests.

Matters needing attention of rose flowers

1. Anthracnose of rose flower

[symptoms] the plaque occurs at the edge of the leaf, semicircular, dark brown at the edge, brown to light brown in the middle, and small black spots on the plaque in the later stage. The pathogen overwintered on the diseased leaves. Under warm and humid conditions, spore germination invades leaves. The plant cluster is too dense and the moisture retention time is long, so it is easy to develop the disease. Anthracnose occurs sporadically and can be treated simultaneously in the prevention and treatment of black spot and leaf spot.

[prevention and control] clear the garden in time in late autumn and early winter, collect diseased fallen leaves and burn them. Strengthen maintenance, proper pruning, thinning too dense branches, so as to make good ventilation and light transmission. Spray 20% Longke bacteria (thiobacillus copper) suspension 500 times or 78% Cobo (wave) if necessary. Manganese and zinc) wettable powder 600x liquid, 75% Dakonine (chlorothalonil) wettable powder 600x liquid, 50% Shibaogong or Shibake (prochloraz) wettable powder 1000 times liquid, 25% carbon tetralin wettable powder 500x liquid.

2. Rose powdery mildew

[symptoms] the disease can occur in leaves, petioles, shoots and buds. There are irregular powdery mildew spots on the adult leaves, and the diseased leaves gradually turn brown from the tip or edge of the leaves, resulting in the drying and shedding of the whole leaves. Young leaves infected, chlorosis spread, gradually expanded, the edge is not obvious, young leaves on both sides of the white powder spots, and then covered with the whole leaf, the leaves become light gray or purplish red. The new leaves are wrinkled and deformed. After infected with petiole and new shoot, the internodes were shortened, the stem became thinner, some of the diseased shoots were withered, and the diseased part was also covered with white powder. The bud is infected, the bud and pedicel are covered with white powder, the calyx, petals and pedicels are deformed, and the serious ones wither and die, losing their ornamental value. Powdery mildew overwinters on diseased buds. Planting is too dense, nitrogen application is too much, poor ventilation, lack of sunlight, easy to develop.

[control] varieties resistant to powdery mildew were selected. When pruning in winter, pay attention to cutting off diseased branches and buds. The disease resistance was improved by applying less nitrogen fertilizer and more phosphorus and potassium fertilizer during the disease onset period. Pay attention to ventilation and light, timely drainage after rain, to prevent moisture retention, can reduce the incidence of disease. At the initial stage of the disease, 20% triadimefon EC 1000 times or 20% triadimefon sulfur suspension 1000 times and carbendazim wettable powder 1000 times were sprayed. If there is resistance to the above fungicides, 12.5% nitrilazole EC or 3000 times Teflin wettable powder can be sprayed instead. Spray Baume 2 / 3 stone sulfur mixture or 45% crystal stone sulfur mixture 40 / 50 times before sprouting in early spring to kill overwintering bacteria.

3. Roseflower beetle

[characteristics] Rose beetles mainly damage roots, leaves, buds and other parts, which seriously affect the yield and quality of flowers.

[prevention and control] Light trapping, willow trapping, oscillating trapping, etc. When the damage is serious, 2.5% deltamethrin 2000-3000 times or 50% phoxim 1000-1500 times can be sprayed. The effect is good, but it must not be sprayed at flowering stage.
