Rubber tree pruning plastic pruning, rubber tree is a very famous foliage plant, but also a common outdoor plant. Its appearance is very atmospheric and beautiful, and many people make small potted plants and plant them indoors, which has high ornamental value. The following is the understanding of rubber tree pruning, shaping and pruning.

Rubber tree pruning 1 1, coring, that is, the method of removing the terminal bud of the branch or cutting off the top of the branch to promote the germination of its lateral branches.

Principle: remove the terminal bud of the main branch, eliminate the top advantage, and make the lateral buds germinate and grow.

2. Short cutting is a method of cutting off 1/3 or 1/2 on the upper part of the whole main branch to promote the germination of side branches of the main branch.

Principle: cut off the top branches, eliminate the top advantages, and let the cut lateral buds germinate and grow.

3. Bud carving is a method of carving in the exposed part of the main branch to promote the lower bud to germinate at the carving part and form the side branch, which is called bud carving.

Principle: Incision hinders the transport of nutrients and water, generally inhibits the growth of the upper part of the wound and strengthens the growth of the lower part of the wound. It is best to carve buds in spring (mid-April), when 3 ~ 4 leaves of lateral branches can be formed.

4. Pulling branches is to change the extension direction of branches in space with the help of external forces. The principle is to change the polarity of branches by pulling branches, that is, to weaken or eliminate the top advantage of terminal buds. The greater the angle of branch pulling, the stronger the top advantage will be weakened. If it is pulled to a horizontal state, the top advantage will be completely eliminated.

Because the bud tip advantage is enhanced where the angle of branch pulling changes greatly, this kind of bud is easy to germinate and form branches, that is, the bud at the back bend of branch is easy to form tip advantage and sprout to form side branches. The specific operation is: pull the bud-promoting part into an arc shape, so that the bud-promoting part is at the top advantage. If the branch is pulled in spring, it can promote the formation of lateral branches in that year.

Four-season maintenance method of rubber tree

1, rubber tree spring maintenance skills

Rubber trees are robust in nature and simple in management. Put plants in bright places in spring, keep the soil moist, and often sprinkle water around plants to increase air humidity. According to the growth of plants, appropriate fertilization. The temperature rises gradually in late spring, so rubber trees can be moved to semi-light environment or scattered light indoor for maintenance.

2, rubber tree summer maintenance method

Rubber trees can withstand high temperature and scorching sun, but too strong light will also make the leaves lose their luster, which is not conducive to viewing. Rubber trees can be placed in bright light or directly exposed to the sun, but they should be properly shaded at noon to provide enough water for plants to promote their growth.

3, rubber tree autumn maintenance method

When the light is weak in autumn, you can move the rubber tree to a well-lit windowsill or balcony to keep the basin soil moist. In autumn, it is necessary to properly enhance its cold resistance. You can exercise outdoors at low temperature for a while, but you can't frost. Move indoors in time before frosting.

4, rubber tree winter maintenance skills

Rubber trees are not cold-tolerant, and can withstand short-term low temperature of 0℃. But the indoor temperature should be kept at about 5℃. At this time, the growth of rubber trees is at a standstill. It is necessary to ensure sufficient light to make the basin soil dry and wet, and the basin soil is too wet and easy to rot. When the temperature is high at noon, spray water on its surroundings and leaves several times.

Rubber tree pruning plastic pruning 2 rubber tree pruning method:

1. Newly planted cuttings can be cored at one time to promote the growth of 3-4 branches at the base. If the branches are uneven or insufficient, they can be selectively cored again to form a larger and more uniform crown width.

2. Rubber trees grow fast, so they can be pruned again when changing pots every spring, and the vigorous branches can be shortened, and the distribution of branches can be readjusted to inhibit their growth. During the growth period, you can also properly pick the heart, restrain the strong and help the weak, and form a complete and unified plant shape.

3. When the rubber tree is too high, it is not suitable for indoor layout. Tall rubber trees can be pruned again in spring, leaving only 3 ~ 5 branches with a length of 5 ~ 10 cm at the base to reduce the height. After leaf regeneration, a short and strong plant shape can be formed by properly removing the core 1 ~ 2 times.

4. Older and stout plants are not suitable for home layout and can be replaced by new cuttings.

The top of the rubber tree has a strong advantage. If it is not pruned, the terminal bud can germinate continuously, making the trunk grow continuously, while the axillary bud is dormant for a long time and can't pull out the side branches, thus growing into a unique one with poor ornamental value. Therefore, in order to form a round crown, the stem is usually fixed when the cutting seedling grows to about 1 m high. First, the trunk is cut short, and the height is not more than 80 cm.

The axillary buds can germinate quickly after being cut short, and multiple lateral branches can germinate at the same time, and three branches in different directions are selected as the lateral main branches, that is, the primary trunk branches of the tree; After 1 ~ 2 years of growth, when its length reaches 80 cm, it will be cut short again, and the branch length will not exceed 60 cm. Three lateral branches are also selected on both sides of the main branch to form a secondary backbone branch, which can create a "three rights and nine tops" plant shape.

After the tree is formed, it should be pruned frequently to reduce the volume of the crown, and the branches that grow too long should be truncated to maintain the round crown, and at the same time, it can promote the germination of the lateral branches and prevent the cavities from appearing in the tree. If you want to use pruned branches for cutting, you should prune them in early and middle May, when the survival rate of cutting is high.

After many years, the small lateral branches in the tree cavity will become longer and denser, which will affect ventilation and light transmission. The over-dense horizontal branches, parallel branches and inward branches should be drained, and the dead branches should be cut off at the same time to promote the germination of hidden buds and update the crown. When pruning, a large amount of milk will flow out of the incision, so you can quickly seal the incision with cement to prevent excessive milk overflow.

Rubber tree pruning, shaping and pruning 3. Rubber tree propagation method

When rubber trees are sown and propagated, the seeds are germinated first, then inserted into wet soil and covered with a plastic film. If the cutting method is used, it is best to choose thick branches, then cut them into 3-5 branches with scissors and insert them in the sand bed to keep the soil moist every day.

1, sowing and breeding

Rubber trees grow well and can reproduce, mainly by sowing. First, we should select full and robust seeds, and then soak them to accelerate germination. After two days, the surface of seed coat becomes soft, then they are inserted into a wet sand bed, covered with a plastic film, and placed in a warm and humid environment for about 25-30 days to germinate and take root.

2. Cutting

If you want to make the propagation of rubber trees easier, you can use cutting. First, you can choose thick branches, then cut them into 3-5 branches with scissors, and keep the bud ends on the branches. Then, you can insert the branches into a wet transplanting bed, put them in an indoor greenhouse, water them once a day, and transplant them after the seedlings are unearthed, and they can germinate and take root again in about 3-4 weeks.

3. Layered propagation

Layering propagation is also a common propagation method of rubber trees, which is usually carried out in the vigorous growth period of rubber trees, mainly in June and July in summer. Cut off the perennial branches, disinfect them with a small amount of potassium permanganate solution, then coat some plant ash-wrapped incisions, seal them with plastic film, insert them into the wet sand bed, compact them gently by hand, keep the soil moist every day, and take root and sprout about 1 month.
