Common methods of rose propagation

Rose is a flower variety that many people are very familiar with, and it is also a flower that many friends like very much. Because of the high economic value of roses, many flower friends will plant roses as a career. Xiaobian will introduce you to the common breeding methods of roses, like friends can understand together.

roses

1. Plant division propagation

One year before plant division, sufficient fertilizer and watering should be applied near the rhizosphere of mother plants, and the soil should be kept loose and moist to promote a large number of roots to sprout. Because rose tillering ability is very strong, after every time pumping new branch, mother branch is easy to wither, so must be near the rhizosphere shoot transplant to go elsewhere in time, make mother branch still can grow exuberantly. Therefore, from November to December every year, after the plant leaves, or when the buds just sprout in February of the following year, new plants growing strong beside the mother plant can be dug from the big flower pier, each cluster has 2~3 stems, and planted separately with roots. After planting, the stem is cut off from 20~25cm above the soil surface, and it can bloom in clusters after 2~3 years of cultivation.

II. Laying propagation

in that plum rain season of June to August every year, the healthy branch of the current year are selected, bent into the soil, the soil part is cut and embed into the wound with soil blocks, buried in the soil, fixed with bamboo fork or tree branches, the branches are exposed to the ground, the soil is kept moist, roots can be taken in 2 to 3 months, and the next spring can be separated from the mother plant and planted separately.

III. Cutting propagation

Before sprouting in early spring, 1-year old branches with strong growth and no diseases and insect pests are selected, cut into cuttings with a length of about 20cm, obliquely inserted into a cutting bed made of new river sand with a depth of 12 - 14cm, compacted and watered, and the temperature of the sand bed is often maintained. After about 30 days, roots are rooted, and transplanted after germination. Sand bed cuttings healing rooting easier, but in the warm room sunny place or in the field arch plastic shed cuttings, management work to be careful. Softwood cuttings are generally carried out in the plum rain season, semi-mature branches are taken, and the middle and lower parts are cut into cuttings with 2 to 3 nodes and buds, obliquely inserted in the soil, watered after compaction, and transplanted after rooting and germination; old branch cuttings are mostly carried out in the growing season from September to November.

How to raise roses?

Rose is a flower that girls like to receive very much. It not only symbolizes hot love, but also can be very "pragmatic". Sun-dried roses can make tea and drink, and can also make snacks. So how do roses grow in life? What kind of farming methods are there? Below, for everyone to tell about the cultivation method of roses, I hope to help everyone.

Roses are cultivated.

Rose, origin China. Belong to rose order, rose family deciduous shrub, branch pole much needle, odd number feather shape compound leaf, lobular 5~9, elliptic, have edge thorn. Petals obovate, double to semidouble, flowers purplish red, white, fruiting 8-9 months, oblate. Roses are native to China. Rose as a crop, its flowers are mainly used for food and extraction of essential rose oil, rose oil used in cosmetics, food, fine chemicals and other industries. In daily life, people will be rose a series of large flowers gorgeous cultivars (rose) collectively referred to as roses, as a symbol of love. In European languages, rose, rose and rose all use the same word, such as rose in English and DieRose in German. Roses are the national flower of England. The most common hybrid roses in the world today (Rosahybrida, also known as modern roses or modern roses) are mainly the products of hundreds of years of hybridization between many species of Rosa and breeding. Especially from the rose relatives of long flowering, flowering all the year round, branches mainly upward growth and inflorescences protruding open at the top of the plant and other characteristics. Rose language: love, love and beauty, radiance, courage.

Rose likes sunshine, cold tolerance, drought tolerance, good drainage, loose fertile loam or light loam, poor growth in clay loam, poor flowering. It should be planted in a well-ventilated place far from the wall to prevent sunlight reflection, burn the flower bud and affect flowering.

Sunny nature, strong cold resistance. Drought tolerance, waterlogging tolerance, water will lead to defoliation, and even death. Like fertile, loose, moist, well-drained sandy loam. The temperature difference between day and night is large and the dry environment is conducive to growth. Light and Temperature Sufficient sunlight promotes good growth. No matter planting, potted plants should be put in sunny places, daily to receive more than 4 hours of direct sunlight. It cannot be placed in indoor places with insufficient light for a long time. In winter, enter the room and put it in the sun. Suitable growth temperature 12-28℃, can withstand-20℃ low temperature. It is safe to overwinter in Zhengzhou area.

Roses propagation method

1. Cutting method. That is, in early spring, select new sprouting branches, cut them with a sharp knife with a little wood on their stems, and insert them into cuttage beds or small pots after treatment with growth hormone.

2. Grafting method. Every 5-9 days, select full bud on the mother plant of improved seed, cut off 1-2 buds on Baiyutang or rose rootstock, or connect a bud every 8-10 cm on a long branch of rootstock, cut off one section of the branch with one live bud, and insert it into sand bed or container like general cuttage method.

3. layering method. Ground layering. In rose growth period, the rose branch bud under the cut wound, curved buried in wet soil, branch tip a section of the soil surface, when buried in the soil cut new roots, can be cut and planted.

Aerial layering. On the rose branch, choose a suitable part, cut the branch or peel the epidermis 1-1.5 cm, use bamboo tube or plastic bag to wrap a soil ball with a diameter of 6-8 cm at the peeling place, keep it moist frequently, after about 1 month, the wound grows new roots, cut it off and plant it in the seedbed or flowerpot.

4. Plant division method. Generally, roses can be properly planted or rooted in soil to promote the growth of new roots in each branch stem. Combined with pot change, the lateral branches with new roots can be cut open and another new plant can be formed.

How to grow roses

Rose cultivation of soil requirements are not strict, but in alkaline or micro-soil is the most appropriate, slightly acidic soil can also be. Therefore, roses should be planted in ventilated sunny and irrigated, drainage conditions of good fields, fertile loam in the edge of the ground. Rose bogey low-lying easy waterlogging, waterlogging when the lower leaves turn yellow and fall off even the whole plant death. Rose flower bud and germination requirements of the average temperature of 7 degrees or more, from the initial stage of germination to flowering period requires effective accumulated temperature of 365 degrees, generally should be the temperature at that time. Rose florescence most avoid dry hot wind and soil drought, there are water conservancy conditions of the field block can be a bud irrigation. Rose in the process of production and development there are two stop growth period (generally in June-July called summer sleep; November-December said hibernation), at this time no branches, branches do not elongate. Summer dormancy period is the best pruning period for flower picking seedlings. Base fertilizer and winter water can be applied during hibernation period, which lays the foundation for stable and high yield of flower buds in the coming year.

Watering is one of the basic tasks of flower cultivation, but it is also often the reason why plants are easy to die. Watering depends on the pot soil. Once it is dry, it is necessary to irrigate it once. Too wet is easy to cause rotten roots. Every other year to change the pot soil, change the pot to cut off the bottom of the surrounding roots, so that flowers, flowers, flowers Yan.

Scientific weeding, because the seedlings are small, weeds are easy to grow, to do a good job of weeding in real time, do not hurt seedlings and no grass. Keep the soil loose. Fertilization is mainly organic fertilizer, and topdressing is applied four times a year as usual. Animal manure is applied for the first time after the festival, which is called germination fertilizer, and watering is carried out in real time; human and animal manure is applied for the second time before budding or flower picking in late April to promote more and full buds; biological organic fertilizer is applied in May, and winter fertilizer is applied in late autumn and early winter to ensure that seedlings survive peacefully. After flowering in June and winter dormancy period, cut off dead branches, diseased branches and weak branches to sprout new branches. In each period of field management, careful pest control should be carried out.

Rose pot insert, bed insert can be. After insertion, shade and sunscreen should be provided, and water should be sprinkled frequently to maintain a certain humidity and temperature. It takes about a month to root and become a new plant, and it can be transplanted after a year.

The above is the cultivation method of roses for everyone. Is everyone clear? More home improvement just please pay attention.

Desert rose common problems and cultivation methods

In the home life of breeding plants is a common phenomenon, desert rose is a kind of plant, desert rose how much do you know? What is the cause of the yellow desert rose leaves? What is the cultivation method of desert roses? The following small series will take you to understand some knowledge about this area, I hope to help you, take a look together.

The reason for the yellow desert rose leaves

Desert rose leaves yellow reason one: not yet adapted to the environment to buy a new desert rose in the adaptation period, a small number of yellow leaves appear very common phenomenon, is a very normal thing, after a period of time, such as its own adaptation is good. If there are a lot of yellow leaves, or even dying, then it may be other reasons, continue to look down. Two: root rot plant roots need to breathe, keep the soil loose, flower pot airtight easy to cause root rot, once the root rot plant naturally can not absorb enough nutrients. The solution is to remove the rotten parts and loosen the soil. If the root system is completely rotten, it will not be saved. Three: excessive watering from the name of the desert rose can be seen that it is more resistant to drought, each time the amount of watering can not be too much, otherwise it is easy to cause rotten roots, resulting in yellow leaves. Control watering after removing rotten roots. Four: the temperature is too low winter temperature is low, desert roses will be in dormancy, leaves turn yellow, dry, and even drop leaves, are to reduce water evaporation and nutrient consumption, is a self-protection mechanism, do not worry. If you want desert roses to thrive in winter, move them into greenhouses. Five: insufficient light desert rose is a sunny plant, sufficient light to ensure its normal growth. If you're putting it in shade, let it bask in the sun. Six: poor ventilation is bound to lead to poor ventilation plant yellow leaves, serious cases will also appear the whole plant rot death phenomenon. The solution is to take it to "blow", that is, move to a well-ventilated location, such as a balcony, window, etc. Seven: excessive fertilization on the one hand, excessive fertilization will make the soil airtight, on the other hand, the concentration of extracellular solution is too high, root cells die of water loss. The result is root rot until death. So fertilizer should be appropriate, remember not to apply more. Eight: pest desert rose is the main pest scale insects, serious occurrence of all leaves fall off, plant growth point necrosis, and even plant death, but found immediately with cotton swab dipped in water to wipe it, but also in the spawning period and incubation period with 40% omethoate EC 1000-2000 times, or 50% fenitrothion EC 1000 times spray 1-2 times. IX: Diseases

Desert roses are mainly damaged by leaf spot and root rot. When leaf spot occurs seriously, a large number of leaves can be shed. It can be controlled by 500 times solution of 25% carbendazim WP and 1000 times solution of 50% thiophane. Root rot often causes plant root rot and death, can be used 50% thiophane WP 500 times or agricultural streptomycin 1000 times irrigation control.

Desert rose cultivation method

Desert rose culture method one, desert rose mainly with sowing and cuttage method propagation. Sowing in spring is the best, with dibble method, in order to facilitate post-emergence management. Before sowing, the substrate must be disinfected. After emergence, pay attention to the substrate in the sowing tray should not be too wet, otherwise the roots may rot and cause a large number of seedlings to die. Cuttings to grow exuberant season is good. Cut the branches into about 10 cm, dip the lower end in water, dilute the mucus at the incision to prevent cementation and affect the roots. It can be inserted into sand bed or directly inserted into sterilized culture medium, and it can take root in about 15~30 days. When propagating, it is recommended to propagate by sowing, so that the rhizomes of the plants can naturally expand to form good plant shapes. Cuttings can not, but also greatly reduce the ornamental value. Second, in addition, in the cultivation, desert rose branches are easy to grow, affecting the beauty of the plant shape, can be grafted to change its plant shape. Can be at a certain height according to a certain shape of the branches will be cut off, and then take the upper end of the cut branches, with the method of grafting. After grafting, the plants are beautiful in shape, compact in flowering and ornamental. Third, desert roses are more resistant to drought, and the amount of watering each time should not be too much. If there is more water, it is easy to cause root rot, and the branches are also too long, which is more troublesome to trim. In summer, when the temperature is high, water can be watered according to the soil condition. Generally two or three days of watering once, basin can not accumulate water. Winter temperature drops, desert rose also enters semi-dormant period, at this time to control watering properly, pay attention to keep the soil dry, watering once a week can be. Moderate drought is very conducive to the growth of desert roses. Fourth, desert roses prefer phosphorus and potassium fertilizers, usually supplemented once a month or so. Summer growth period requires sufficient fertilizer and water, so that the flowers can flourish and be bright. In addition, combined with the annual pot change, some long-term base fertilizers can be applied appropriately in the pot, such as decomposed bean cakes, bone meal, etc. Desert roses prefer phosphorus and potassium fertilizers, usually supplemented once a month or so. Summer growth period requires sufficient fertilizer and water, so that the flowers can flourish and be bright. In addition, combined with the annual pot change, some long-term base fertilizers can be applied appropriately in the pot, such as decomposed bean cakes, bone meal, etc. The pruning of desert roses is also very important. If you don't pay attention to the usual pruning and let it grow, it is easy to lose its ornamental value. After flowering is the best time to prune, you can choose according to personal preferences. Note: more branches, more flowers, to get more flowers, we must find ways to stay more ramets.
