Soil, the culture method of miniature rose

Miniature rose flowers like to grow in sandy soil with fertile soil and good water retention. If the soil is poorly drained, the soil is hardened. It is very disadvantageous to its growth and may even lead to its death. The soil with more limestone will also affect the absorption and utilization of some trace elements by rose, resulting in chlorosis.

Light

Miniature rose likes light, and it can be illuminated properly during the day, which is beneficial to its growth. But in hot summer, if there is too much direct light, it will also be disadvantageous to the development of buds, and the petals are easy to scorch. So we have to remember to avoid the direct sun.

Fertilizer application

Mini rose has a long flowering period, basically blossoms throughout the year, and has a large demand for nutrients, so it is more fond of fertilizer, so we need to fertilize it every month to ensure adequate nutritional conditions.

Temperature

The suitable temperature for the growth of miniature rose is 15 to 26 degrees. Avoid overheating in summer. If the temperature exceeds 33 degrees, it should be properly shaded. If you want better maintenance in summer, you must maintain good ventilation. The ground can spray water to cool down, but avoid spraying on the leaves.

Have you all learned the breeding method of miniature Chinese rose? Next, let's see what else we should pay attention to!

Culture method of miniature Chinese rose

Miniature rose, its plant type is short, spherical, many flower heads, because of its unique character, also known as "diamond rose". In terms of breeding, we should pay attention to some methods. The following is for us to sort out the breeding methods of miniature rose flowers, hoping to be helpful to you.

Culture method of miniature Chinese rose: pot

⑴ chooses the basin. Miniature rose should choose flowerpots with a diameter of about 20 cm, and purple sand pottery pots are the best.

⑵ soil: if the soil is selected correctly, the flower cultivation will be successful in general, and the mini rose is suitable for choosing loose, fertile and organic matter-rich soil.

To protect the roots with peat is to dig a hole and fill it with peat and plant seedlings in the peat. Because the peat has good air permeability, it takes root faster and the humidity is more moderate than that of garden soil, and it is generally neither too dry nor too wet. After the seedling is big, it will directly penetrate the peat root to the general clay, and it will have no effect.

If there is no peat, build it with improved soil, add some black mud collected by the river, add some rotten tree leaves, add some perlite, and mix it to improve air permeability.

It is recommended that beginners do not put bottom fertilizer when planting or transplanting. It is easy to burn roots if the amount is not well controlled by ordinary people, especially high concentration compound fertilizer. Another layer of soil should be laid on top of the base fertilizer, and the roots should not be in direct contact with the fertilizer.

⑶ planting. Transplant with soil in spring or autumn, pour root water in time after planting, and place it in a bright and ventilated place. After the seedlings are planted and survived, they should be pruned a little to promote their more branches in order to achieve the effect of blooming flowers and leaves.

Culture method of miniature Chinese rose: fertilization

Potted miniature rose should be cultivated with loose, fertile and well-drained soil, which should be planted in the spring and autumn, and should be turned over for 1 to 2 years. The small root of miniature rose plant is shallow, and the management of water and fertilizer is the key to daily maintenance. Water once a day in spring and autumn, once or twice a day in summer, and once from 3 to 5 days in winter and early spring.

During the growth period, liquid fertilizer was applied once from 10 days to 15 days, or compound fertilizer was applied once in January, less fertilizer was applied in summer and stopped in summer. Miniature rose has strong germinating power and should be pruned. During the flowering period, cut off 8 cm to 12 cm with the branches under each crop of flowers. Should be re-cut before spring germination, generally leaving only 3 to 4 main branches, leaving 3 cm to 5 cm at the base of each branch. Like big flower rose, miniature rose is prone to powdery mildew and black spot. On the basis of comprehensive control, 5 degrees of stone-sulfur mixture can be sprayed before germination, and 800 times of methyl topiramate can be sprayed every half a month after germination, which has a better preventive effect.

Culture method of miniature rose: pruning

1. Winter pruning is heavy pruning, which will be cut to the root 5CM or even shorter, the main purpose is to dwarf the plant and control the plant type, of course, tree type rose and rattan rose are not this case. Tree rose and Fujimoto rose only need to cut off the tender tip, 1/3 light cut. Micro-month pruning is mainly plastic surgery, first cut off withered branches, disease and insect branches, cross thin and weak branches, for strong growth, symmetrical plant type, cut off the whole plant 1max 3. For the plants with weak growth, about 2 prime 3 of the whole plant was cut off, leaving 3 strong main branches.

2. There should be a pruning after flowering in spring. The second leaf can be trimmed lightly after flowering, and lateral branches will be sent out after pruning. Most varieties will begin to bud in about 40 days (the lateral branches are covered with seven leaves).

3. There should be another pruning before the coming of autumn to make the autumn flowers more and bigger. this time, the third batch of side branches should be cut off, cut short on the main branches, leaving about the length of 20CM, so that they can send thick branches.

Culture method of miniature Chinese rose: daily management

Potted plants should be planted in pots with loose, fertile and well-drained soil, and should be turned over for 1 to 2 years. The small root of miniature rose plant is shallow, and the management of water and fertilizer is the key to daily maintenance. Water once a day in spring and autumn, once or twice a day in summer, and once from 3 to 5 days in winter and early spring.

During the growth period, liquid fertilizer was applied once from 10 days to 15 days, or compound fertilizer was applied once in January, less fertilizer was applied in summer and stopped in summer. Miniature rose has strong germinating power and should be pruned. During the flowering period, cut off 8 cm to 12 cm with the branches under each crop of flowers. Should be re-cut before spring germination, generally leaving only 3 to 4 main branches, leaving 3 cm to 5 cm at the base of each branch. Like big flower rose, miniature rose is prone to powdery mildew and black spot. On the basis of comprehensive control, 5 degrees of stone-sulfur mixture can be sprayed before germination, and 800 times of methyl topiramate can be sprayed every half a month after germination, which has a better preventive effect.

Propagation methods of rose culture

(1) the method of sowing and propagation of Chinese rose.

Sowing and propagation are mainly used to reproduce rootstock seedlings and breed new varieties. Plants sown in spring can blossom in the autumn of the same year. Winter-sown plants need to be covered against the cold in the cold winter. Harvest the fruit during the ripening period from October to November, cool it in the sun for a few days, then crush the pulp with a lighter mill, wash the seeds out with water, and store them in the sand.

Rose is sown indoors from December to February of the following year. Before sowing, prepare the soil, apply sufficient base fertilizer, and form a 1m wide bed. The row spacing of sowing is 20cm, the plant spacing is 4~5cm, the optimum temperature for germination is 22-25 ℃, and the seedlings germinate in about 30 days. Flowers can be planted from May to June of that year. In order to promote the robust development of seedlings, the flowers should be removed when they appear in bud and can be grafted one year after emergence.

(2) the method of cutting propagation of rose.

Cuttage is the main method of propagation of Chinese rose, and twigs can be cut in spring and autumn in the south. Spring planting takes place from March to April, when the relative humidity is high, it can take root 25 days after planting, and the survival rate is high. Autumn planting begins in late August and ends at the end of October, when the rooting period is 10 to 15 days longer than that of spring planting.

In addition, it can be combined with a large number of branches cut in winter at the end of autumn for winter hardwood protection, and cuttings in the south can be cut in the open field, preferably in the greenhouse. Most of the cuttings in the north are in spring. If you want to cut in autumn or winter, you should cultivate them in a greenhouse or sub-cold bed. When cutting is treated with hormone, it can promote rooting.

(3) the method of grafting and propagation of Chinese rose.

Grafting is also a common method in production, especially for excellent varieties whose cuttings are difficult to take root. Rootstocks should choose species with strong adaptability and resistance to powdery mildew and brown spot, such as wild rose, pink rose, thorn rose and so on. Multi-use branch grafting or bud grafting.

Branch grafting should be carried out in the dormant period, mostly from December to February in the south, and before leaf buds sprouting in spring in the north. Bud grafting can be carried out in the growing period, and September is suitable for multi-branch bud grafting of different varieties on tall rootstocks, so as to cultivate tree-like rose.

(4) the method of striping propagation of Chinese rose.

Rose flowers are carried out in the period of exuberant growth, and can take root in 1 month. After rooting, they can be cut off from the mother and planted with soil. Rattan or semi-rattan rose uses wavy crimping method. Bend the branches wavily in the pit, cut the lower end of the branches into the pit with a sharp knife, and press them to maintain the soil moisture.

The new root can be cut off from the mother plant after 25-30 days, and the seedlings can be formed independently. The upright rose adopts the high-altitude striping method. From the top 20cm, 0.5cm was peeled and covered with rotten leaf soil and plastic sheet. it could take root in about 30-40 days, and the pot culture was cut off directly.

(5) the method of ramet propagation of Chinese rose.

It is often used for varieties that are difficult to survive by cutting. when the month is in a subordinate state, the soil buds grow into new branches and dig up the surrounding soil. for example, when there are more fibrous roots at the base of the new branches, they can be cut with scissors and potted respectively. At the same time, the aboveground part was trimmed to reduce water evaporation and improve the survival rate of transplanting.
