Rubber leaves are plump and beautiful, with broad and beautiful leaves and luster. The red top bud looks like a cloud, and the stipules are like red tassels falling down after splitting, which is quite charming. It is a famous potted foliage plant. Here are the propagation methods of rubber trees:
The propagation method of cutting rubber tree 1. Cutting method: this method is easy to operate, easy to survive and fast to grow.
(1) The cutting time is at the end of spring and early summer, which can be combined with pruning. The middle branch of 1-year-old semi lignified is mostly selected for cutting.
(2) After cutting, in order to prevent too much milk from flowing out of the cut and affect the survival, the cut should be sealed in time with plaster or grass ash.
(3) The length of the cuttings is based on the standard of keeping 3 buds. Cut off the lower leaf, close the upper two leaves, and bind them with fine plastic rope to reduce the evaporation of the leaf surface. Then, the cuttings are placed on the cutting bed with plain sand or frog stone as the substrate.
(4) After transplanting, keep the transplanting bed with high humidity, but do not accumulate water. The suitable temperature is 18-25 ℃. Sprinkle water on the ground frequently to improve the air humidity, and do a good job in shading and ventilation. Take root in about 2-3 weeks. After potting, put a little shade, and gradually increase the light after the sprouting of new buds.
2. High branch pressing method (diagram): it is more convenient for family flower breeders to propagate with high branch pressing method, and the success rate is also higher.
Prepare scissors, ropes, media and water
When peeling, you can use a knife to carve a circle at the upper and lower ends of the branch
Use a knife to gently peel and scrape the selected part from top to bottom
Wrap the peeled part into a cylinder with plastic wrap
Fasten with string at the lower end
Slowly add the loose and moist nutrient soil into the plastic cylinder
Tie the upper end with string, and then tie a circle in the middle 1. The specific method is as follows: select 2-year-old branches with proper size, well-developed and full tissue, make light ring peeling with a width of about 1cm at the site to be covered with soil, and apply 30-50ppm NAA solution, then wrap up the ring cutting site with wet soil or moss mixture or vermiculite with sufficient moisture, wrap the outside with plastic film, tie the lower end tightly, and leave holes at the upper end, so as to facilitate Aeration and irrigation. Then put it outside in the sunshine to strengthen the daily maintenance of the mother plant. At ordinary times, pay attention to check the humidity of the package. If it is too dry, inject water with a syringe, or loosen the upper string to inject water, and then tie it firmly to ensure that it is wet. Do not dry or over wet, and do not apply fertilizer. Pay attention to maintenance, strip in June and root in July August. After rooting, the potted plant can be cut. 2. Check for rooting: it can be seen through the plastic film that the bag is full of root whiskers, and even the root system will penetrate out of the bag. At this time, the plastic film can be cut together. Then remove the string and plastic film, grow them together with the mud in the flowerpot, place them in the shade for maintenance, and carry out normal management after serving the flowerpot. 3. It has been proved that the high pressure method is convenient for management and the survival rate is 95%.
