The cutting method of the latest rubber tree

Rubber tree is native to Brazil and is now widely cultivated in tropical Asia. It is cultivated in Taiwan, southern Fujian, Guangdong, Guangxi, Hainan and southern Yunnan. Hainan and Yunnan are planted more often, and cutting methods are commonly used to propagate. It is easy to survive and grow fast. Let's take a look at the cutting methods of rubber trees.

Treatment of rubber tree cuttings

The cutting time of rubber tree is in late spring and early summer, when the air humidity is relatively high, the cuttings are easy to survive, which can be combined with pruning. The quality of rubber tree cuttings has a direct impact on the survival rate of cuttings, generally choose the sturdy branches which are completely lignified at the end of the surface every other year as cuttings, this kind of branches have sufficient nutrients, so they are easy to take root and have strong disease resistance. The length of cuttings is based on the retention of three buds, cut off the lower leaf, close the upper two leaves, and tie them with thin plastic rope to reduce leaf evaporation.

Cutting method of rubber tree

Rubber tree cuttings are cut on the bed with plain sandy soil or frog stone as substrate. Keep the bed with high humidity after cutting, but do not accumulate water. The suitable temperature is 18-25 ℃. Water is often sprinkled to the ground to improve air humidity, shading and ventilation are done well, and it can take root in about 2-3 weeks. Put it in a shaded place after the pot, and then gradually increase the light after the new buds sprout.

Water insertion method of rubber tree

Rubber tree water insertion is usually at the end of April or early May, the sturdy rubber tree old strip is cut into 10-12 cm segments as cuttings, each leaving 2-3 nodes, the cut is best in the upper and lower part of the bud, cutting off the leaves. Then put the insert in an empty glass bottle, each bottle about 10 pieces, until full. Inject 25ppmABT rooting solution into the bottle, soak the cuttings 1 / 2 in the solution, soak for 20 / 24 hours, pour the rooting solution and replace it with clean water. After that, change the water every 2-3 days and put it indoors. About 10 days later, the cortex of the submerged branches of the rubber tree will appear white dots, which is the budding root tip. After the root grows, it grows rapidly, and the buds at the top of the cuttings begin to sprout, which can be put on the pot in 20 days.
