Culture methods and matters needing attention of the latest rubber trees

Rubber tree is a famous potted foliage plant, also known as rubber tree, Brazilian rubber and so on. It is a large tree of the genus Ficus of Moraceae. It has high ornamental value and is very suitable for indoor beautification. Small and medium-sized plants are often used to beautify the living room and study. Medium and large plants are suitable to be arranged on both sides of the foyer of large buildings and in the center of the lobby. Let's take a look at the breeding methods and points for attention of rubber trees.

Growth habits of rubber trees

Rubber tree is native to Brazil and is widely cultivated in tropical Asia. It is cultivated in Taiwan, southern Fujian, Guangdong, Guangxi, Hainan and southern Yunnan, especially in Hainan and Yunnan. Sex like high temperature, humid, sunny environment, suitable growth temperature 20: 25 ℃, avoid direct sunlight. It is also shady but not cold-resistant, and the safe overwintering temperature is 5 ℃. Resistant to air dryness. Avoid clayey soil, not resistant to barren and drought, like loose, fertile and well-drained slightly acidic soil.

Propagation methods of rubber trees

1. Cutting method: the cutting time is in late spring and early summer, which can be combined with pruning. Cuttings often choose one-year-old semi-lignified middle branches, and the wound should be sealed in time with cement or plant ash. The length of cuttings is to keep 3 buds as the standard, cut off the lower leaf, close the upper two leaves, and tie them with a thin plastic rope. The cuttings are then cut on a bed with plain sand or frog stone as the substrate. Keep the plug-in bed with high humidity after insertion, but do not accumulate water, the suitable temperature is 18-25 ℃, often sprinkle water to the ground to improve air humidity, and do a good job of shading and ventilation, it can take root in about 2-3 weeks.

2. Striping method: select 2-year-old branches with appropriate size, good development and abundant tissue, and make a light circular peeling of about 1 cm in width in the predetermined part of the soil, and apply 30~50ppm 's naphthalene acetic acid solution, then wrap the ring cutting part with wet soil or moss mixture or vermiculite that absorbs enough water, wrap it with plastic film on the outside, tie it tightly at the lower end, and leave holes at the upper end to facilitate ventilation and irrigation. Pay attention to maintenance, pressing in June and rooting from July to August. After taking root, the potted plant can be cut off.

Culture methods of rubber trees

1. Temperature: the rubber tree has the best temperature of 20-25 degrees, even if it is above 30 degrees, it can grow well, but in winter, if the temperature is too low, the rubber tree will produce a large number of fallen leaves and its cold tolerance is very poor. Northern China needs to spend the winter in a greenhouse.

2. Lighting: it is really good to say that sunlight is the food of plants, and sunshine is also a treasure in the cultivation of rubber trees. giving it enough sunlight can make it thrive and give it proper shade from May to September.

3. Fertilization: the existence of fertilizer is like calcium supplement, which can enhance its "health". Fertilization is also one of the key points in the cultivation methods of rubber trees, which can reduce the occurrence of markings and make the leaves bright. Just use nitrogen fertilizer. Stop fertilizing in winter.

4. Pruning: when it's time to prune the rubber tree, cut off the branches inside the crown, inward branches and thin branches to maintain its internal ventilation, good light transmission and overall shape. Usually, in the cultivation method of rubber tree, the basin must be turned once every 2 years, and materials such as rotten leaf soil are added to reconfigure it. It likes loam soil with loose and good drainage.

5. Soil: rubber trees like fertile, loose and slightly acidic soil, and basin soil should be prepared with 4 parts of rotten leaf soil, grass ash soil plus about one part of river sand and a small amount of base fertilizer.

6. Watering: when it is hot in summer, the rubber tree grows faster and should be fertile and watery, but to avoid stagnant water in the basin. Gradually reduce watering after entering autumn, promote plant growth and enrichment, which is conducive to its overwintering.

Matters needing attention in the culture of rubber trees

1. The suitable temperature for rubber tree growth is 25: 30 ℃. If the leaf is lower than 3 ℃ in winter, the leaves will turn yellow and fall off, so it should be placed in the sunny place indoors in winter and keep the room temperature above 10 ℃. When more than 35 ℃ in summer, the plant should be moved to a cool and ventilated place for maintenance, and timely water spray to cool down.

2. Rubber tree is a plant of Moraceae, and the whole plant contains milk. Therefore, immediately after each pruning, the incision should be blocked with cement or coated with charcoal powder, so as not to drain too much juice and cause water loss and death.

3. The rubber tree needs to change the direction of the basin regularly in the seedling stage, in order to prevent the plant from growing on one side, resulting in small and correct plant shape and beautiful appearance.

4. After the general rubber tree seedlings, due to the larger and larger roots, resulting in soil consolidation, hindering soil ventilation, resulting in rubber trees yellowing, serious may die. It is appropriate to change the basin before the new buds grow in spring every year. Loosen the soil every 15 to 20 days until it returns to normal growth.
