How to breed and cultivate rubber trees?

Rubber trees are generally propagated by cuttings and striping. During the growing period of spring and summer, the middle and upper biennial robust branches should be selected as cuttings. Cut in autumn, select the Lignified branches of the current year as cuttings. As long as the bed temperature can be kept above 15 ℃, the cutting time is unlimited. In addition to cutting in the bed, water cutting can also be carried out. From April to May, take the long branches of the same year's 15cm, remove the lower leaves, wait for the cut to dry, insert them into a glass bottle filled with water, put them in the place of scattered light, change the water once a week, and take root after about one month.

Rubber trees are cultivated in the open field in South China, and most of them are pot ornamental and indoor furnishings in Guizhou Province. It is necessary to maintain a temperature of 5: 10 ℃ for winter indoors. The slightly acidic culture soil rich in humus, loose and fertile and well ventilated should be selected and put on the basin or change the basin before Frosts Descent in autumn or before sprouting in spring.

Adult plants change pots once a year, cut off koji roots and add fertilizer, and apply liquid fertilizer dominated by nitrogen fertilizer twice a month during the growing period. And keep the basin soil moist at any time, pay attention to watering and spraying more than 2 times a day in spring drought and summer days, but pay attention to the basin soil can not accumulate water. It is necessary to control the water in autumn and winter, and the basin soil is not dry or watered.

When the plant grows to about 80cm, it is necessary to remove the heart and promote the lateral branches. For the long branches of 80~100cm, it is necessary to cut short at the full buds to form a plump round crown. When the plant grows to 6 years, it can be transferred to wooden barrel or large vat for cultivation, instead of pouring the pot, just change the soil, add base fertilizer and cut off the curved root system.

For the long branches of 80~lOOcm, it is necessary to cut short at the full buds to form a plump round crown. When the plant grows to 6 years later, it can be cultivated in wooden barrels or large vats, instead of pouring the pot, just change the soil, add base fertilizer and cut off the curved roots.

Propagation and cultivation of Rubber Tree

Rubber tree, also known as Indian rubber tree, gum banyan, is Moraceae, banyan evergreen trees. The tree is tall and strong, with a height of up to 30 meters. Leaf blade large, oval, leathery, shiny, densely alternate. Because the petiole is small and the leaf is slightly drooping, it is also called vertical leaf rubber. Common varieties are: Phnom Penh rubber tree, leaf margin is golden; flower-leaf rubber tree, leaves with many irregular yellow-white patches; white-spotted rubber trees, leaves with many white patches; red-bud rubber trees, leaves thick, dark green with red, leaf bracts red; yellow-spotted rubber trees, leaves green with irregular yellow-green spots; Lilia rubber trees, leaves are dark green, the main veins and leaf bracts are bright red. American leaf rubber tree with pinkish new leaves and dark green near the main vein of mature leaves surrounded by milky white; Venus broad-leaved rubber tree whose leaves are reddish green when young and reddish brown after growth.

Cuttings and high branch pressing methods are usually used to propagate, mainly cuttings, twigs and old branches can be cut alive, each section has 4 sections, the lower leaves are removed, and the top two leaves are tied together to reduce transpiration. The cut is sealed with plant ash or plaster to prevent milk from flowing out. It is better to cut from May to September, and it is easy to cause cuttings rot in hot summer. The best cutting medium is river sand and peat, and the cuttings are about 1 beat 2 deep in soil. The cuttings are maintained under the shade shed at a suitable temperature of 25 ℃. The cuttings can take root in pot after 6 weeks. Weak species or horticultural varieties can be propagated by pressing, peeling in a ring of cadres, covering the moss to keep moist, rooting in about 3-4 weeks, and putting on the basin after cutting off. Water insertion method can also be used to tie 10 cuttings together, insert them into water 1 stroke 3, change water once a day, and take root 50 days later.

Rubber trees like high temperature, humidity and sunlight. The temperature above 25 ℃ is very beneficial to the growth. Cold resistance is also strong, in Fujian, Guangdong area can spend the winter outdoors in winter. Generally, the overwintering temperature should be above 3 ℃. The leaves are thick, leathery and can withstand strong sunlight. But direct sunlight in summer can lead to a lack of gloss on the leaves. Putting it in too much shade will cause fallen leaves. When placing the room, you should choose a bright place as much as possible. It grows rapidly and needs a lot of fertilizer. It is best to choose garden soil, rotten leaf soil and put some base fertilizer at the bottom of the basin. Liquid fertilizer can be applied once a month during the growth period. Powdery mildew and brown spot are easy to occur in patients with poor ventilation.

The diseases include wind anthracnose, leaf spot and gray mold, which are sprayed with 65% Dysen zinc 500 times; pests are harmful to scale insects and thrips, and are sprayed with 40% omethoate EC 1000 times.

Rubber tree is a large evergreen foliage plant, green all the year round, beautiful and generous, is a common courtyard tree and pot ornamental plant. It can be planted as street trees and courtyard trees in Guangxi and Fujian, and as the main display in many planting pots in northern gardens. The growing season of large and medium-sized potted plants can be arranged on both sides of the foyer and square of large buildings and arranged into flower beds. In winter, it can be decorated in the hall.
