What are the pruning methods of Phyllostachys pubescens? Phyllostachys pubescens is an indoor potted plant and a very popular foliage plant. Very suitable for beautifying and decorating the home environment. Bamboo needs pruning when it grows vigorously. What are the pruning methods of Phyllostachys pubescens?
What are the pruning methods of Phyllostachys pubescens? 1 Phyllostachys pubescens stems and leaves grow too densely. When branches and vines grow too fast, pay attention to pruning the whole plant to make it natural and beautiful. Cut off the base 2-3 cm away from it with a sharp knife. Do not use scissors. Incision will make the wound squeeze and wet, making it difficult to heal.
Usually, bamboo is not suitable for pruning, because there is only one growth point, and pruning is only possible unless the main stem is about three centimeters thick and there are buds on the stem. Even if there is a new branch, the original one is gone. There is only one way to become a cauldron, that is, to raise three or four trees in a cauldron, which will look full of flowers when they grow.
Propagation method of Phyllostachys pubescens
1, ramet propagation: In summer and autumn, the lateral branches of a large area of Phyllostachys pubescens are cut off as a whole, with some aerial roots, and planted directly in wooden barrels or bowls, which not only has high survival rate, but also has quick forming effect. This is one of the simple methods used in the propagation of Phyllostachys pubescens.
2. Cutting propagation: Dendrocalamus latiflorus can be cut in spring and autumn, with cutting effect in April-May in spring and 9-65438+1October in autumn. Cutting because the temperature is suitable during this period, the cutting of stem nodes heals and takes root, and the survival is fast. The cuttings are annual lateral branches with rich stem tissue and vigorous growth, and the cuttings are 20-25 cm long, and the leaves at the base are cut off. Retaining upper leaflets, cutting off long aerial roots and retaining short aerial roots to absorb water are beneficial to rooting.
Seedbed planting is carried out with a mixed substrate of coarse sand and peat or humus soil. After planting, it takes about 1 month to maintain 25-27 degrees Celsius and high air humidity. After the cuttings take root, the axillary buds on the stem nodes also begin to germinate and spread the leaves. In order to accelerate the growth of seedlings, the room temperature should be kept above 65438 00 degrees Celsius, and the management of fertilizer and water should be strengthened. The seedlings can be made into commodities in the second year after cutting.
3. Seeding propagation: Seed sowing is also a common propagation method of Phyllostachys praecox, but it is less used than the first two methods. Phyllostachys praecox blooms in summer. In order to improve the seed setting rate, artificial pollination is needed, and secondary pollination is carried out at 9- 10 in the morning and 3-4 in the afternoon, with high pollination success rate. It takes 15 months from pollination to seed maturity, and attention should be paid to ventilation and fertilizer and water management in the seed development stage to promote full fruiting.
Before sowing, soak the seeds in warm water at 40 degrees Celsius for 10 hour, and sterilize the sowing soil at high temperature. Phyllostachys praecox has large seeds and can be planted as needed. After sowing, the room temperature is kept at 20-25 degrees Celsius, the box mouth is covered with plastic film, and the humidity is kept above 80%. Generally, it germinates 20-25 days after sowing. If the room temperature is too low when sowing, it will not only affect the emergence of seedlings, but even cause waterlogging and rot of seeds.
Cultivation method of bamboo
1, illumination: Kikkomania likes warm and humid environment, and avoids drought and direct sunlight, otherwise it is easy to cause dead leaves. In summer, bamboo should be placed indoors or under a shade shed, not exposed to the sun on the balcony, which is easy to die. When the temperature drops to 6 degrees Celsius in winter, bamboo should be moved indoors to keep warm.
2. Watering: The water content of Phyllostachys pubescens should be sufficient, and the cultivated soil must always be moist. During the summer growth period, water 1 time in the morning and evening, and water the leaves frequently to keep the leaves bright and the air moist. If the water evaporates slowly in winter, water it 1 time every 3-4 days and 1 time every day.
3. Fertilization: Bambusa bambusa is a fertilizer-loving plant, so we should pay attention to proper fertilization. During the growth of Phyllostachys praecox, 1 times pancake fertilizer should be applied every half month. If the fertilizer is sufficient and appropriate, Phyllostachys praecox will grow a pleasant leaf color.
4. Pests and diseases: Phyllostachys pubescens is vulnerable to scale insects, and its stems and leaves are vulnerable to scale insects. It can be cleaned with an old toothbrush and sprayed with 40% omethoate 1000 times. The common diseases of Phyllostachys pubescens include leaf spot, gray spot and stem blight, so attention should be paid to timely prevention and control.
5. Pot changing: Potted bamboo needs to be changed once a year, and the pot changing time is from March to April. When changing pots, remove the old soil, cut off the dead roots of Phyllostachys praecox, and then add decomposed organic fertilizer or phosphorus and potassium fertilizer as base fertilizer.
What are the pruning methods of Phyllostachys pubescens? 2 1, the whole plant is pruned.
When domestic Phyllostachys pubescens grows vigorously, a clean and sharp gardening scissors should be prepared, and branches and leaves should be cut off 2-3 cm away from the root of the plant, so as to help Phyllostachys pubescens form a strong root system, and the cut branches and leaves can be used for cutting propagation.
2, top processing
During the curing period of Phyllostachys pubescens, it can also be cut with a sharp knife. When this pruning method is adopted, because the nutrients will be dispersed from the top to the base, it can promote the plants to sprout too many green branches and leaves and keep the plants round and beautiful.
Step 3 trim and reshape
Under uneven illumination, bamboo bends easily. At this time, plants will lose their original beauty and need to be trimmed and reshaped immediately. You can use a clean knife to cut off the redundant lateral buds on the big bamboo wood, and straighten the main stem with a piece of cloth to restore the upright posture.
4. Preventive measures
If there is only one growing point, it is not suitable for excessive pruning, otherwise the growth of the plant will weaken or even die. When the main stem grows to 3 cm thick and buds have grown on the branches, pay attention to pruning and apply disinfectant to the wound.
5. Trim diseased leaves
Yellow leaves will inevitably appear in the process of bamboo cultivation, so it should be pruned in time when it is found. Of course, diseased leaves should also be cut off, and diseased leaves and dead branches should be trimmed in time to avoid infection. When pruning, use a special knife to cut directly from the yellow leaves and the base of the diseased leaves. If the condition is serious, take the pot and cut it off together with the rotten roots to avoid deterioration.
Step 6 Trim the side buds
Bamboo will grow many lateral buds during its growth, which will make the whole plant look bloated and reduce its ornamental value. Therefore, the lateral buds should be cut off with scissors after they grow out, so that the plant type will look better, save a lot of nutrition and be beneficial to its growth.
7. Whole pruning
If it is found that the overall plant type of Phyllostachys pubescens is poor and the plants are long, all the long branches should be cut short to control their height. For the branches that grow too densely, thinning treatment should be carried out to keep the proper thinning degree, so that pruning treatment can save a lot of nutrients and promote better growth.
