How to cut rubber trees is of high ornamental value. Rubber trees are generally propagated by cutting. It is not difficult to improve the survival rate of rubber trees as long as the technical essentials of cutting are mastered. Let's see how to cut the rubber tree.

Hevea brasiliensis 1 How to propagate Hevea brasiliensis by cutting? Cutting method is widely used, simple to operate and fast to grow.

Combined with pruning and cutting in summer, the highest temperature during the day is about 30℃, and at night it is about 15℃, which is the easiest to take root. In winter, cuttings can be pruned by new plants that survived that year, and cut indoors around New Year's Day, and the temperature is kept above 65438 08℃.

Plain clay or sand is used to cut basin soil. Plain clay is easy to fix short cuttings without lodging, but it has poor air permeability, so the basin bottom needs to be padded with drainage layer, and plain sand can be used to erect columns to prevent lodging.

In summer, it is best to choose biennial semi-lignified intermediate branches, and the survival rate can reach over 90%. The survival rate of annual cuttings in winter is low, generally below 60%. In order to prevent excessive milk outflow from affecting survival, it should be sealed with cement or plant ash immediately after cutting. Cutting length is based on three buds. Cut off the bottom 1 leaf, seal the top two leaves, and tie them tightly with plastic rope or iris to reduce leaf evaporation. Keep the soil moist, but don't accumulate water. Sprinkle water on the ground frequently to increase the air humidity and do a good job of shading.

Single-bud propagation of rubber tree saves cuttings, has a large number of propagation and a high survival rate.

In the north, combined with indoor heating in winter, from June 165438+ 10 to February of the following year, seedlings are cut in shallow pots or blank pots, and the soil is cultivated and flattened every other year.

Select the robust regenerated branches of the year, each node 1 leaf (bud eye is in leaf axil), cut into several sections for cutting, and leave 0.5 ~ 1cm above the bud when cutting to prevent the bud from wilting, and all the leaves below the bud point are reserved. The cut cuttings should be put into clean water, the white milk at the incision should be washed away, the petiole should be directly tied to the stem with thin thread, and then the cuttings should be cut according to the plant spacing of 5 cm. The cutting depth should be slightly exposed to the soil surface. After inserting, cover the plastic cover, put the basin in front of the sunshine window or in a warm place and put it on the radiator with a wooden board to keep it at 20~25℃. When the soil is white, water it with a watering can and keep it moist. It will take root in 20~30 days.

Roots grow rapidly after cutting. In early April, it can be put into a pot filled with fertilized culture soil, and it can be moved to the outdoor for maintenance in mid-May.

How to cut the rubber tree 2 There are wonderful ways to cut the rubber tree.

First, the cutting time

The cutting time is selected in summer, generally from the end of June to the end of July. At this time, the temperature is high, the air humidity is relatively high, and the cuttings are easy to survive.

Second, the choice of cuttings

The quality of cuttings directly affects the survival rate of cuttings, so it is necessary to strictly choose cuttings for cutting, and generally choose thick branches with incomplete lignification on the surface every other year as cuttings. This branch is rich in nutrition, easy to take root and strong in disease resistance. On the other hand, if you choose too woody branches, it is difficult to take root and survive, while if you choose too delicate branches, it is easy to rot.

Third, the preparation work before cutting

One alcohol lamp (or a cup of boiled water), several sterilized cans (boiled water) and one cutting bed can be replaced by wooden cases (the length of wooden cases depends on the number of cuttings, and the depth is 15cm). Drill holes evenly at the bottom of the wooden box for water seepage, and then spread 5cm thick coarse river sand (washed) and coarse sand.

Fourth, the operation method

Quickly cut the selected robust branches into sections of 12 ~ 15 cm, and quickly put them on alcohol lamp (or boiling water) to burn (or scald) the cut parts, as long as the white juice of rubber trees in the tower does not continue to overflow (note: this is the key to the survival of cuttings. The cut part of a burn or scald has two purposes. One is to burn or scald the cutting site. The second is to prevent the bacteria in the sand or air of the cutting bed from infecting the wound and causing decay. )

Remove the redundant leaves, leaving only two leaves, put them in cans and bottles, fill them with clear water (water should be dried 2-3 days in advance), and put them in sunny places. Spray clean water on the leaves 2-3 times a day, reduce the temperature and change the bottle of water every 2-4 days. Cutting in sunny days at high temperature for 8 ~ 10 days can produce white roots. When the roots grow to 3 ~ 5 mm long, they can be planted in a wooden box filled with river sand, with a planting depth of 7 ~ 9 cm, and can be directly inserted.

After spraying enough water, cover it with a plastic cover and spray clean water once a day in the morning and evening. 10 ~ 15 days later, you can put the cuttings in a flowerpot with plain soil in the shade, take root after half a month, break off the extra axillary buds, leave two, water them with dilute fertilizer, and gradually move them from the shade to the full light.

How to cut rubber tree 3? When was the rubber tree cut?

Cuttings of rubber trees from June to July

The pruning time of rubber trees is usually between June and July. At this time, the air humidity is high and the climate is warm, which can increase the chances of rubber trees to survive and adapt to the surrounding environment in a short time. The south can also choose to cut or survive in May.

Cutting method of rubber tree

1, leaf cutting

Pruning a healthy leaf on a rubber tree as a cutting, drying it in a bright environment for a period of time, choosing loose and breathable sand and adding some carbendazim to the prepared soil for disinfection can reduce the chance of getting sick every day.

2. Cutting process

Cut the leaves of rubber trees into the soil to a depth of about 2 cm. Cutting too deep will affect the growth of root system, and then watering will keep the soil moist, but water accumulation should be avoided. After cutting, put it in a good environment and wait for about 45 days to take root.

3. Maintenance after cutting

In the process of rooting, the leaves of rubber trees should be kept at about 30℃ and sprayed with water regularly. In the later stage of cultivation, the yellow leaves should be pruned in time to reduce nutrient consumption, and at the same time, the water should be watered according to the dry and wet conditions of the soil, so that there can be no water accumulation.
