A woman must raise roses once in her life. How can she raise big and beautiful roses? Friends, let Huahua take you to learn! How to cut flowers in January? Generally, when roses are dormant in early spring or late autumn, mature branches with 3 to 4 buds are cut for cutting. If Twig Cutting, shade properly and keep the seedbed moist. Generally, rooting can take place 30 days after cutting, and the survival rate is 70% to 80%. When cutting, the survival rate is higher if rooting powder is dipped in branches& lt; Prophase rooting & gt; Preparation of materials:
A bottle of mineral water, a bag of rooting powder and a section of rose branches
Operation steps:
1. First dissolve the rooting powder with sterile boiling water; After mixing, dip the pruned branches (preferably 5-8cm) into the base for 2-3cm. Soak for 10-15 seconds.
2. The mouth of the mineral water bottle is cut into a small triangular mouth with a knife for cutting.
3. Put the soaked branches into mineral water with a depth of about 1 / 3. Do not cover the bottle mouth, place it on the windowsill and other places with light.
Note: you don't need to add water on the way, just wait for it to take root; The water temperature must be well controlled, and the bottom of the bottle can be properly shaded; There is no need to change water in the whole cutting cycle.
Late transplanting
Mineral water cutting is only to improve the survival and rooting rate of rose. When the branches grow roots, they need to be transplanted into the soil（ According to experience, the best way is to add soil to the water instead of adding water to the soil)
Preparation of materials:
Disposable plastic cup, normal temperature water.
Operation steps:
(1) Add about 1 / 2 of water to the disposable cup;
(2) Put the large granular soil at the bottom, then put the branches at the appropriate position (ensure that the root system is in the water), slowly put the powdered garden soil, and put the planting soil 2-3cm above the root system;
(3) Add water to the full, and then put it in the sun, no tube;
(4) When the soil in the cup is dry to about 80%, you can tear off the cup and transplant it with a soil ball.
2. Maintenance method of rose
Breeding methods and precautions
1. Temperature: like warmth, afraid of heat, more resistant to cold. 22-25 ℃ is the most suitable temperature. If the high temperature lasts above 30 ℃ in summer, the flowering will be reduced, and the quality of rose flowers will be reduced and enter a semi dormant state.
2. Sunshine: like sunny, well ventilated, well drained and windproof environment, avoid dark and humid breeding environment. Shade in summer, otherwise the flowers are easy to lose water and dry.
3. Moisture: like humid environment, the relative humidity of the air is best controlled between 75% - 80%. Can withstand a certain degree of drought. In summer, it is best to spray water once in the morning and evening to maintain a humid environment and promote the growth of flowers and leaves. Water should be dried water to reduce the temperature difference between basin soil and water.
4. Soil: the soil should preferably contain organic matter, fertile, loose, acidic and good drainage. Hardened soil and calcareous soil are not conducive to the growth of rose.
5. Fertilization: thin fertilizer should be applied every 10 days during summer flowering, or soybean cake and poultry manure can be soaked in water and mixed with water for topdressing after closed fermentation, so as to make the plants flourish and break the dormancy state of rose in summer.
6. Pruning: remove diseased branches, weak branches and degraded branches in time, and properly adjust the plant height. At the initial stage of germination, the buds should be sparse, and the side buds and auxiliary buds on the flower branches should be removed in time, so as not to disperse the nutrition.
3 diseases and insect pests
① Aphid disease
It mainly sucks the juice of rose leaves, especially the young leaves and shoots. The leaves of the affected plants wither and fall off, and their excreta can also induce coal pollution disease. They are the main pests transmitting the virus.
Prevention methods:
1. Use the yellow plastic plate to induce adhesion after oiling.
2. Spraying 80% dichlorvos 500 times solution during the occurrence period; Or spray 40% Omethoate 1000 times.
3. 44z% ethylammonium phosphate 50-100 times solution can be applied to rose stems.
4. Protect and use natural enemies to kill, such as ladybug, aphid lion, aphid Apodemus, etc.
② Botrytis cinerea
The diseased buds are gray and black, which can prevent the diseased buds from turning brown and dying as soon as the flowers open. When the flower is invaded, some petals turn brown, shrink and corrupt.
Prevention methods:
1. The diseased part shall be removed in time to reduce the source of infection, and the withered rose shall also be cut off in time.
2. Proper ventilation shall be conducted to avoid excessive temperature difference between day and night and high humidity. When watering, pour it from the edge of the basin, and do not make the leaves and flowers retain water.
3. Spraying protection at the beginning of onset. When using 1:1:100 times Bordeaux solution, it can be sprayed once every 2 weeks.
4, spray method: can use 50% speed Kling wet powder 2000 times liquid, or 50% carbendazim 500 times liquid spray 7~10 days once, continuously 2~3 times, each time spray liquid quantity is not less than 50~60 kg per 67m2. ③ Dead branch disease
It usually occurs in the branches and stems. The disease spot is initially a small red spot, gradually expands into dark color, the center of the disease spot becomes light brown, and the brown and purple edges around the disease spot are obviously compared with the green of the stem.
Prevention methods:
1. Autumn did not collect the diseased dead branches and burned them.
2. Pruning shall be carried out on sunny days.
3. When the disease occurs, it can be prevented and treated by spraying 50% rujunte wettable powder, 70% chlorothalonil wettable powder, or 1000 times of 50% carbendazim wettable powder.
