Introduction of cuttage methods of Eucalyptus: soilless cutting and water cutting

It is one of the most popular indoor plants in the world. The main propagation methods are sowing and cutting. The following small series will explain the cutting propagation method and the management after cutting.

Vigorous growth of Eucalyptus

The cutting propagation method was soilless cutting

From the mother plant which has been growing for several years, 6-8 cm of annual branches are cut, or combined with changing pots and re cutting in spring, the cuttings are used as cutting materials. Remove the inserted part of the leaves, cutting in the previous use of water bubble perlite as the matrix, diameter of 15 ~ 20 cm plastic flowerpots, pot bottom with a tray, in order to receive exudate. Each pot of 3 or single plant, about 1.5 months after cutting can take root, after cutting, often water to keep moist. After transplanting, it should be placed in the indoor weak light place to strengthen the management of fertilizer and water. After rooting, the nutrient solution should be poured in the pot once a week, and 100ml each time.

Note: do not replenish water on the same day to avoid affecting the concentration of nutrient solution. The bottom hole is blocked with a small stone. The perlite or fine sand is placed in the middle. The rock surface or sand surface is low and the basin side is 1 cm high. If perlite is used for potting, it is better to press a layer of river sand on the top (to increase the compactness). At this time, 10 cm-12 cm cuttings can be cut from the adult duck foot wood, and the bottom is cut into an inclined plane. If there is rooting powder, it can be dipped in a little or not Insert 2 / 3 of cuttings into sand or perlite, 3-4 plants in each pot, and then pour water through the basin. Place the basin in a plastic basin or other container containing water. The water level in the container should always be 1 / 2 higher than that in the cutting basin. Then, place a large transparent plastic cover on the cutting basin and place it in a bright place with scattered light. The temperature is kept at 15 ℃ - 25 ℃ for 30-40 days The seedlings can be transplanted into a 6-8-inch pot. The soil should be filled with fine screened high-quality agricultural fertilizer, humus soil and fine sand. The soil should be well mixed with fertile and nutritious soil at the ratio of 3:2:1. After planting, it should be watered and placed in a semi shady place for 7 days, and then transferred to a bright place for management.

Soilless cutting of Eucalyptus

Water cutting: take a large bottle of empty Coca Cola, high foot glass bottle, big mouth cup, etc. for water cutting, wash it clean, and fill it with clean water (tap water). The cuttage is mainly carried out in spring. The annual branches are cut 8-10 cm, the lower leaves are removed, and fixed and inserted into the bottle (the bottom of the cuttings is 1 cm away from the bottom of the bottle). Each bottle can be inserted with 2-3 branches of transparent plastic After 30-35 days, white roots with a length of 0.5 cm-1 cm will grow at the bottom of the cuttings. At this time, they can be removed from the upper pot according to the above method.

The cultivation and management of the cuttage branches of the tree: the soil for pot planting is composed of peat soil, rotten leaf soil, 1 / 3 perlite and a small amount of base fertilizer, and can also be potted in fine sand. Indoor cultivation can see about 4 hours of direct sunlight every day can grow well, in bright indoor can watch for a long time. The amount of water to be watered depends on the season. More water is needed in summer. Water once a day to keep the soil moist. In spring and autumn, water every 3-4 days. If too much water or waterlogging, easy to cause root rot.

During the growth period of summer, the fertilizer should be applied once a week, and the amount of nitrogen, phosphorus and potassium can be used after loosening the soil. In contrast, nitrogen fertilizer was applied less in leaf spot species, while excessive nitrogen fertilizer would cause the patch to fade and turn green. It grows slowly and tends to have long branches, so it is necessary to shape and trim it regularly. Every spring before the germination of new buds should be changed pot, remove part of the old soil, potted with new soil. When it is too large to grow in the laboratory, it can be pruned by changing pots.
