How to raise desert roses, breeding methods and precautions of desert roses / 6 simple tips

We know that desert rose has many functions and functions, and its main function is to watch flowers, but in order to make it blossom smoothly, we must understand how to raise desert roses, otherwise it will not only be difficult to blossom but also cause plant death. today we will introduce the breeding methods and matters needing attention of desert roses.

How to raise desert roses

If you want to raise a plant well, you should give it the most suitable environment and the most scientific method according to its growth habits, so how to raise desert roses? We need to know its growth habits first.

Growth habits of desert roses

It likes high temperature, drought and sufficient light environment, the most suitable temperature is 25-30 ℃; like loose, breathable and well-drained sandy soil, the soil had better be rich in calcium; not afraid of drought and stagnant water; like the sun is not resistant to shade; like fertilizer but afraid of high concentration of fertilizer and raw fertilizer; cold tolerance is weak.

Culture methods and matters needing attention of desert roses 1. Create the most suitable environment

1. Lighting

Desert rose likes sunny environment best, it can thrive in full light, and good light can promote its flowering, unlike other plants: even during the dormant period in winter, desert roses still need to enjoy plenty of sunshine to survive the winter.

[note]: do not plant desert roses in a shady environment. If there are conditions, you can put them in a sunny place for maintenance. If it is out of reach of the sun, you can use fluorescent lamps, scattered light, and so on.

2. Temperature

Desert rose can adapt to the high temperature environment, its average temperature can be maintained at 30 degrees, so its growth is the most exuberant in summer, in other seasons should try to create an environment of more than 20 degrees, and basking in the sun is one of the best ways.

[note]: in the breeding method of desert rose, we must pay attention to keep warm for desert rose in winter, because its cold resistance is weak, it should be moved back to the room in time to ensure that the temperature is above 10 degrees in order to make it survive the winter smoothly.

3. Soil

The best soil is rich, loose, well-drained sandy soil, we can use sand, rotten leaf soil to make, but not to increase the calcium content, can add some bone powder.

[note]: good drainage of soil is very important for desert roses, because desert roses prefer dry environment, if not enough drainage, not only can not create such an environment, but will easily produce stagnant water, which will do great harm to the roots.

Second, the culture method of desert rose should be scientific.

1. Watering

I mentioned earlier that desert roses like dry environment, but we can't grow them without watering at all, so how to keep desert roses on watering? Before each watering, you can determine whether the basin soil is completely dry, and only the soil is dry and then watered to avoid it from being in a wet environment.

[note]: do not water too much each time, and you must stop watering in winter, otherwise it is easy to cause frost injury or wilt of desert roses.

2. Fertilization

Desert roses do not have high requirements for fertilizer, but they should apply sufficient fertilizer during the growing season, such as once a month in spring and summer, mainly slow-acting fertilizers, such as compost and so on.

[note]: when applying fertilizer, the concentration of fertilizer must not be too high, and the amount of fertilizer should not be too much, otherwise it is easy to cause fertilizer damage and prevent the leaves from thickening and blooming.

3. Pruning

Flower lovers plant desert roses mainly to give full play to its ornamental value, while pruning can not only maintain its beautiful plant shape, but also promote it to sprout new branches and make it blossom continuously, so pruning is a very important work.

[note]: the residual flowers and dead branches should be cut off after flowering to avoid the waste of nutrition. in addition, it is necessary to pay attention to cutting off the branches that are too dense and high, otherwise they are easy to grow steeply.

January Flower events complete Handbook Weather characteristics of January: this month is the lowest and coldest month of the year. Lesser Cold, around the "39 th Day", most parts of our country have entered a period of severe cold. On January 20, Greater Cold, the cold air in the north frequently went south, the frost was heavy and the snow was thick, and the lowest temperature of the year appeared.

This month's flower conservation, the most important thing is to do a good job in greenhouse, greenhouse and indoor cold-fearing flowers, bonsai, etc., followed by tree pruning, litter cleaning and land preparation, and other auxiliary work. First, flower culture 1. The kinds of flowers that can be sown in the greenhouse in January are: big rock tree, asparagus, gentleman orchid, ball root begonia, cyclamen, winter coral, African chrysanthemum and so on. The ornamental plants that can be sown in the open field are: rose (Elizabeth), Phyllostachys pubescens, Fugui seed, holly, fiery thorn, palm, heather, heather, disease-free son, privet, wisteria, Sapium sebiferum, Luan tree and so on. two。 The ornamental plant species suitable for open field or covered with plastic film in January are plum blossom (green calyx, palace powder, etc.), red leaf plum, rose (Elizabeth, abundant flower, miniature, etc.), cherry blossom, wax plum (heel), Spiraea, yellow poplar, pomegranate, silver bud willow, ten gong Lao, Luo Han song, June snow, three branches, golden peach, golden bell, spray snow, welcome spring, Jasminum and so on.

Green Luo, Zhu Jiao, etc. In addition, you can also cut cloves, Lingxiao, Tamarix, grapes, sea immortal flowers, Shu Shu, eight immortal flowers, Platycladus mollissima, figs and other branches for sand storage, waiting for cutting in March. 3. One-year-old seedlings of apricot, fruit plum, mountain peach and hairy peach can be used as rootstocks for grafting culture of excellent varieties of plum blossoms, then buried on the seedling bed and covered with plastic film to keep moisture and prevent cold. In Guangdong, between Lesser Cold and Greater Cold, budding breeds four seasons tangerine, kumquat and so on; using excavated wild rose buds to graft excellent varieties of rose, using rose variety Elizabeth as rootstock, cutting or splitting superior varieties of rose, grafting and cutting are carried out at the same time, and plastic film is covered to keep moisture and prevent cold. 4. The ornamental plants that can be cultivated by pressing in January are: purple magnolia, camellia, plum blossom, brocade belt flower, gardenia, stick stem begonia, Luohan pine, snowball, Qionghua, Yingchun, Admiralty, eight immortal flowers, hemp leaf hydrangea, spray snowflake, pomegranate, red maple and so on. 5. The species of herbaceous ornamental plants that can be cultivated in January are: Ophiopogon japonicus, auspicious grass, onion orchid, leek orchid, hairpin, purple calyx, purple back evergreen, Jianlan, Chunlan, Cymbidium, kidney fern, shoot stem, iris, hanging orchid, evergreen, Guangdong evergreen, rooting, pineapple, Little Taran, Yanshan ginger, tortoise bamboo, aloe and so on.

Harvest seeds in January, if there are mature asparagus and magnolia seeds in the greenhouse, they can be picked and sown, mature winter coral seeds, or sown indoors at this time. The seeds of Phyllostachys pubescens, Firethorn, holly and rich seeds can be picked in January, and the seeds can be sown after the seeds are exposed to white. In January, the seeds stored in sand should be checked frequently, including magnolia, Michelia, heather, holly, etc., to see if there is mildew in the seeds. If mildew occurs, the seeds must be poured out and re-scrubbed, and clean fine sand must be replaced for storage; if the seeds are found to be dry, spray water should be given in time. If it is found that the seed has been white or the radicle has stretched out, it must be sowed immediately and covered with plastic film or rice straw, pine needles and other heat preservation and moisturizing. 7. Transplanting and planting in January, the grass flowers that can be transplanted and planted in not too cold areas are: carnation, kale, calendula, daisy, etc.; in relatively cold areas, the seedlings such as carnation, kale, goldfish grass, pansy and primroses can be put on the pot, first placed in a simple plastic greenhouse, and then used as a display of street flower beds, green fields and flower borders after the return of air in spring. In January, most deciduous shrubs and green trees can be transplanted and planted Such as hibiscus, pomegranate, bauhinia, begonia, ginkgo, maple, maple, wax plum, plum blossom, white magnolia, red leaf plum, cherry blossom, papaya, two Qiao magnolia, crape myrtle, wisteria, Lingxiao, Linden, Liriodendron, green peach, Chinese tallow, red Spiraea, three branches, rose, Robinia pseudoacacia, dragon claw locust and so on. Evergreen tree species, especially Cinnamomum camphora and Fa Qing, should be transplanted in advance to December or postponed to February this month except for special circumstances. Of course, in places of shelter, intensity shearing is carried out after transplanting, and cold protection and watering management are strengthened after transplanting. In January, despite the cold weather, the collection of wild tree stumps in the south of the Yangtze River did not affect the collection of wild tree stumps in the process of afforestation and land preparation, mainly deciduous tree stumps, such as Ulmus pumila, Sparrow Plum, triangular Maple, Yingshanhong, crape myrtle, Acer sinensis, wisteria, Wintersweet, Wild Plum, Elaeagnus angustifolia, Weisheng Spear, etc. For evergreen stumps, such as Phyllostachys pubescens, Maoer thorn, medlar, holly, oak, etc., strength shearing must be done and most of the leaves must be deleted. Both deciduous stumps and evergreen stumps should be cultivated by shallow burying and high cultivation, and covered with grass curtain to prevent freezing. Second, prevent the cold from overwintering. The cold prevention and heat preservation work this month is the top priority in the management work, a little negligence will bring serious losses to bonsai and bonsai overwintering. According to the lower limit of the lowest temperature that can be tolerated by different flower species, a special environment for them to survive the winter should be created, either in a greenhouse, in a greenhouse, at home, or buried in open soil. In a simple plastic greenhouse of no less than 0 ℃, ornamental plant species that can withstand a low temperature of about 0 ℃ can be placed, such as Penglai pine, Tianmeng, one-leaf orchid, star anise, sunflower, kidney fern, brown bamboo, southern bamboo, peach leaf coral, Michelia, Chunlan, magnolia, rich seeds, Daphne, cycad, calamus, Phoenix tail bamboo, phenanthrene bamboo, white bamboo and so on. In a double-layer plastic greenhouse of not less than 5 ℃, you can put ornamental plant species that can withstand a low temperature of about 5 ℃, such as southern fir, rubber tree, jasmine, pearl orchid, magnolia, pocket coconut, bottle orchid, calla lily, spring feather, tortoise back bamboo, kumquat, daidai, lemon, sunflower, camellia, tea plum, Jianlan, orchid, epiphyllum, Ling Arrow lotus, big Buddha belly bamboo, Belgian rhododendron, triangular plum, five-colored plum and so on. Flower species that can withstand low temperatures of about 10 ℃ can be placed in double-layer plastic greenhouses or greenhouses with auxiliary heating equipment. Such as variable leaf wood, flower leaf taro, taro, pineapple, pepper grass, colored leaf grass, rich bamboo, fish tail sunflower, Brazilian iron, wealth tree, reticulate grass, red (green) gemstone, hulk, green emperor, silver queen, Milan, Cymbidium, Phalaenopsis, Cartland, Oncidium, Magnolia, gold tree, South American iron tree, desert rose, pink, poinsettia, golden bract, coral flower, etc., during the very cold period. From 4: 00 p.m. to 9: 00 p.m., it is appropriate to cover the grass curtain on the roof of the greenhouse, and the grass curtain can not be stopped until the temperature turns warm. In very cold days, it is necessary to strengthen the inspection of heating facilities and personnel on duty, especially from 5 o'clock to 6 o'clock in the morning, do not cut off the fire and power, otherwise it is easy to cause freezing damage to the plants. For those more hardy species of potted flowers and bonsai, such as Chimonanthus praecox, plum blossom, begonia, Yingshanhong, pomegranate, elm, sparrow, oak, crape myrtle, wisteria, yellow poplar, Luohansong, triangular maple, cypress, round cypress, summer cypress, Platycladus orientalis, small bayberry, Chinese wolfberry, holly, opposite section white wax, etc., can be buried together with flowerpots, when not less than-10 ℃, generally will not occur frost injury In particularly cold weather, cover with plastic film or soft grass to keep warm. It is worth noting that whether it is placed in a greenhouse, in a greenhouse, or at home for potted flowers or bonsai, including ornamental fruits and foliage plants, in addition to maintaining the appropriate temperature, we should also do a good job of ventilation and ventilation. Doors and windows can be opened around noon when the temperature is highest in the day to prevent falling flowers, leaves and fruits. When giving ventilation, we must also try our best to avoid cold air blowing directly on the plant. In January, special attention should be paid to the inspection of greenhouses and greenhouses in the process of air-conditioning going south, and glass breakage and film tearing were found, and leakage plugging should be carried out in time to avoid freezing the potted flowers. In the greenhouse to provide coal, gas, oil heating, should also be carefully checked, there should be no air leakage, smoke leakage into the greenhouse or greenhouse, in order to prevent falling flowers, leaves and fruits caused by smoke damage. In order to promote peony blossom during the Spring Festival, potted peony can be placed in a greenhouse, heated to 18 ℃ to 25 ℃ during the day, and kept at about 10 ℃ at night, adding 4 to 5 hours of light every day (incandescent light). It is expected to blossom before and after the Spring Festival. Potted plum blossoms, wax plums, camellias, camellias, camelli Potted hyacinths, tulips, daffodils and freesia, which have been placed in the greenhouse in December, will strengthen the management of water and fertilizer and are expected to be used for decoration and display during the Spring Festival. two。 In the watering management of potted flowers in January, the most important thing is to pay attention to the temperature of watering and spraying water, that is, to keep the water temperature roughly consistent with the soil temperature. if the gap between them is too large, it is easy to cause adverse reactions of potted plants. even make the plant deciduous, rotten root or death. Watering time is best arranged for 2 to 3 hours before and after noon. Secondly, according to different plant species, determine the number, times and methods of watering. For most of the potted flowers and bonsai placed in the greenhouse, greenhouse and bedroom, it is appropriate to keep the potted soil moist, and those with low temperature should reduce watering correspondingly. When the temperature rises, the amount of water can be increased and foliar spray can be given. For most foliage plants, we should not only keep the basin soil moist, but also pay attention to spraying water on the leaves, and always keep the leaves of the plants clean. For the species of foliage plants that are not very cold-resistant, such as Fendai leaves, taro, taro, variable leaf trees, etc., when the air temperature is close to the lowest temperature that the plant can bear, the amount of water should be specially controlled. For those species of potted flowers that will blossom before and after the Spring Festival, such as camellia, tea plum, Belgian rhododendron, poinsettia, melon and leaf chrysanthemum, wax plum, plum blossom, primrose, hyacinth, longevity flower, calendula, etc., and ornamental fruits such as firethorn, daidai, bergamot, lemon, rich seed, kumquat, golden bean, winter coral, not only to keep the potted soil moist, but also to spray water on the plant to facilitate the expansion of flower buds. It can also increase the bright color of the fruit. Although potted flowers do not need much water in January, inspection should be strengthened to prevent water shortage of potted flowers placed in remote parts, and timely supplementary watering of dried plants in pot soil can reduce the death of overwintering plants. For newly planted green trees and flowering shrubs, they should be checked frequently and watered in time, especially for those evergreen ornamental plants after transplanting, they should also be sprayed properly around noon to prevent the leaves from shrinking and falling off due to excessive air dryness. 3. Fertilization for most of the greening trees and flowering shrubs planted on the ground Such as Begonia, Magnolia, maple, gardenia, seven-leaf tree, camphor, Linden, crape myrtle, Lingxiao, sweet-scented osmanthus, wax plum, plum, cherry, cherry-free, acacia, Luan, palm, Schima superba, runnan, purple tree, camptotheca, peony, golden bell, yellow poplar, grape, coral tree, rose, hydrangea, red leaf plum, Yu Li, elm leaf plum, horse Liriodendron wood, Shu Shu, Prunus mume, Muxiang, du Ying, Golden Salix, hanging Elm, Cryptomeria fortunei, Cryptomeria fortunei, Cedar, Robinia pseudoacacia, Robinia pseudoacacia, White Silk Plum, Hibiscus, clove, crape myrtle, Photinia, Phyllostachys pubescens, Pomegranate, Loquat, etc. If the fertilization task is not completed in December, cake fertilizer, barnyard manure, pond mud and septic tank cleaning materials can be buried on the periphery of the tree root system while the soil is turned over, so as to lay a good material foundation for the growth and flowering of spring. Potted flowers placed in a greenhouse of about 10 ℃ to 15 ℃, such as Belgian rhododendron, shrimp flower, golden bract, Ruixiang, melon and leaf chrysanthemum, primrose, cyclamen, red mouth daffodil, tapered begonia, hyacinth, tulip, colorful pineapple, orchid, orchid, crab claw orchid, etc., can continue to apply low concentration of potassium dihydrogen phosphate solution, in order to facilitate plant growth and bud blooming. For most of the potted plants, foliage plants and bonsai put in the greenhouse, as the plants are dormant in winter, fertilizer should be stopped, otherwise it is easy to cause rotting roots of the plants to die. 4. Continue pruning hedges, green walls and balls that have not been pruned in December, and continue pruning flowers and shrubs that have not been pruned in December, such as rose, crape myrtle, wood incense, Lingxiao, wisteria, Fenghua rose, camphor, Fatong, Chinese tallow, heather, pomegranate, red leaf plum, papaya, wax plum, plum blossom, palm, grape, etc. After pruning, base fertilizer is applied to the periphery of the root system to meet the needs of its spring growth. According to the original composition requirements, bonsai plant species dominated by shearing and supplemented by pruning, such as hammer elm, sparrow plum, triangular plum, Fujian tea, oak, white wax, bayberry, Elaeagnus angustifolia, pyracantha, June snow, juniper, etc., can continue to be adjusted and trimmed according to personal aesthetic taste to lay a good foundation for the growth and formation of spring. At the same time of pruning, plants that have not changed pots for many years can be changed. 5. Pest control can cut off the trunk or big branches such as crabapple, plum blossom, elm leaf, papaya, loquat, blue peach, cherry blossom, red leaf plum, etc., which are eaten by peach red-necked longicorn beetles, and burn off the sawed stems and branches. Cleaning up the leaves under the trees such as rose, rose, grape, crape myrtle and so on, and burning them centrally after collection can reduce the occurrence of leaf diseases in the coming year. On the trunk and branches of Haitong, Fatong, privet, firethorn, persimmon, gardenia, plum blossom, red wax scale, cotton blowing scale, shield scale, sagittal scale, pink scale, line scale, etc., spraying and killing with high concentration of quick culling, quinathion, parathion, stone sulfur mixture can effectively inhibit the occurrence of scale insects in that year. Powdery mildew on melon-leaf chrysanthemum in greenhouse and Botrytis cinerea on primrose leaves can be controlled with thiophanate-methyl to prevent it from spreading to other plants. To carry out comprehensive control of scale insects and coal pollution on daidai, bergamot, kumquat and other plants in the greenhouse, first wipe off the coal spots on the leaves and the insects attached to the dry branches with a wet cloth, and then spray pesticides such as dimethoate. Botrytis cinerea on cyclamen plants in the greenhouse can be sprayed 1000 to 1500 times with 50% prohydantoin (mainly composed of isocarbamide) wettable powder. 6. Compost pours rapeseed cake, bean cake and tea seed cake into a pool or tank for soaking and fermentation, so as to provide pot flowers for pouring during the growing season; layer-by-layer accumulation of withered grass, branches and fallen leaves with garden soil, ignition and burning, self-made burning soil can be used as covering soil for sowing and breeding in spring; mixed fermentation of barnyard manure, pond manure, tobacco powder, chicken dung and pigeon dung with garden soil can be used as fertilizer for the preparation of cultivated soil. 7. For the nursery that has not been reclaimed in December, ploughing can be carried out in the first ten days of January. while ploughing the garden, cake fertilizer, compound fertilizer and soil fertilizer are applied, and after freezing through the winter, ditches are made to make beds in early spring for sowing and planting seedlings. Because January is particularly cold, the plant species suitable for styling must be those with soft branches, good toughness, ginkgo, melon seeds, yellow poplar, velvet cypress, cypress in June, snow in June, cypress, cypress, five-needle pine, yellow pine, black pine, bayberry, canary, wax petal, weeping spear, banyan, wisteria and so on. After modeling, it is best to put it indoors or in a simple plastic greenhouse, and then move to the outside after the air is warm in spring, which is conducive to the healing of damaged parts. For the plants shaped with brown rope or wire 1 or 2 years ago, if obvious constriction is found in the binding site, the original ligature should be removed and flat traction should be carried out again. In January, the management of some shallow pot tree stump bonsai, shallow basin landscape bonsai and small, miniature bonsai should be strictly strengthened. Small and miniature bonsai should be buried on the indoor sand bed; tree stump bonsai should prevent the basin soil from freezing, injure the hairy roots of the plant, cause the disintegration of man-made cemented rocks, and prevent the plants planted on the pebbles from withering after being frozen, it is appropriate to put them in an ice-free place and water and spray them regularly to ensure that they can survive the winter safely.
