Melaleuca przewalskii is one of the most popular tree species. It has elegant tree shape and beautiful and unique flower shape. It can be planted alone to show its individual beauty, and it is also suitable for piece planting and viewing. Especially in the open lawn to plant in groups, can highlight its landscape effect. So, how is red Melaleuca cultivated? What matters should be paid attention to in breeding red Melaleuca? Come and have a look.
Cultivation methods of Melaleuca koraiensis (basic knowledge): the best growing soil: cultivated substrate of Melaleuca koraiensis likes rich and humid acid soil, but also can tolerate barren and arid soil. Potted cultivation soil with loose water permeability and water and fertilizer conservation was applied.
Growth humidity requirements: keep the soil moist in spring and autumn, strengthen watering in midsummer, and sprinkle water on the ground around the basin. Watering 1-2 times a day after planting of Melaleuca rosea should be done through the soil layer, and at the same time, the branches and leaves should be watered to keep the branches and leaves moist, which has an important role in reducing water transpiration and maintaining the water balance in the plant. Spraying water on branches and leaves is another important link for survival after planting. Some plants can survive even if some soil is scattered.
The best growth temperature: Callistemon paniculata is a positive tree species, which can tolerate - 5 ℃ low temperature and 45 ℃ high temperature, and the suitable growth temperature is about 25 ℃.
The best growth light: Melaleuca is a neutral plant, but the sunshine is sufficient and the growth is vigorous. It needs a long time of light to promote its growth.
Notes on Cultivation of Melaleuca koraiensis: application of fertilizer: fertilization is very important for the rapid recovery of plant growth. It can be applied with a thin amount of nitrogen 15 days after planting, and high-quality organic fertilizer once a month later. After that, high quality organic fertilizer can be applied once or twice a year.
Key points of watering: watering 1 ~ 2 times a day after planting should be done through the soil layer, and at the same time, the branches and leaves should be sprayed to keep the branches and leaves moist, which can reduce water transpiration and maintain the water balance in the plant. Spraying water on branches and leaves is another important link for survival after planting. Some plants can survive if some soil is scattered. If the water is sprayed on the branches and leaves, they can survive. They can be transplanted between June and September. At this time, the weather is hot and the water evaporation is large. Therefore, the frequency of spraying water on the branches and leaves should be appropriately increased.
Pruning tips: after transplanting, the water balance will not return to normal soon. Pruning before seedling emergence is an effective measure to reduce water transpiration. It is beneficial to keep the water balance in the plant, especially in the hot summer. The pruned branches and leaves account for about one-third of the whole plant, mainly inner bore branches (shade branches) and fresh shoots. When transplanted in winter and spring, the top branches with flower buds should be reserved so that they can blossom in summer after transplanting and receive greening effect.
Breeding points: the main propagation method of Melaleuca crassifolia is sowing and cutting. Because the seeds are very small. Small seed sowing method should be adopted. The seedlings germinated about 10 days after sowing and could be transplanted when the seedling height was 3 cm. It is suitable for transplanting in spring and autumn. When the temperature is high in summer, the branches should be pruned properly and the seedlings should bloom 45 days after transplanting. Cutting propagation should be carried out from June to August, and the cuttings should be semi mature branches, about 8 ~ 10cm long. At the base of cuttings, the mature technique of the previous year was slightly carried. Set up shade shed for slotting bed and keep the environment moist.
Pest control: stem rot is the main disease of Melaleuca rosea. It is advisable to remove the diseased seedlings and spray Bordeaux solution for control. The pests include tiger, mole cricket, green weevil and so on, which can be controlled by 1000 times of trichlorfon or 1000 times of dichlorvos. Spray once every 7 days, 2-3 times continuously.
Experience of culturing Melaleuca: pay attention to the following points in culturing Melaleuca:
1. Cultivation medium: mud carbon soil, straw mushroom mud, river sand, red mud, pond mud, etc. can be used. The proportion of 8 parts of mud carbon soil, 2 parts of river sand or 8 parts of fermented straw mushroom mud and 2 parts of river sand can grow well. The medium-sized seedlings grow well, and can be planted with 7 parts of argillaceous soil or fermented straw mushroom mud, three parts of red mud and pond mud.
2. In the process of management, the soil should be kept moist. Generally, the seedlings should be drenched with 1000 times of urea water, once every half a month. The medium seedlings should be mixed with peanut skin and Norwegian compound fertilizer once a month.
3. It is necessary to insert bamboos for supporting; the vertical branches are more colorful, and the thousand layer branches are relatively soft, and the length is about 50 cm. Therefore, it is necessary to insert bamboo for supporting, so that the main stem is obvious and the plant shape is plump.
4. According to its use, it can be trimmed into cylindrical, spherical, tower and natural shape. According to the modeling requirements, the corresponding pruning method is adopted.
5. More attention should be paid to pest control.
Conclusion: through understanding the growth habits, breeding methods and precautions of Aquilaria erythrophylla, we can better cultivate beautiful plants.
