Azalea culture method

China's top ten famous flowers - azaleas, also known as Yingshanhong, won the praise of the ancients: "The two branches are held in the hand, the fine does not seem to be human, the flower is this thing, the whip is the mother." The rhododendron is called "Shanke", and it is called "Panhua Five Sisters" with Camellia, Cyclamen, Shilahong, and Bells. Today, Xiaobian simply introduces the breeding method of azaleas .

1. Site cultivation Xiqiao requires indoor and outdoor environments: indoors are used for winter cold protection, the coldest is not less than one 2C - one 3C, outdoor is to spend the summer, Jiangnan area from mid-April to early November Raised outdoors, requires the natural shade of deciduous trees, or artificially set up the shade to create a semi-rainy and cool growing environment. The ground should have a drainage slope and the flower pots should rest on the shelf.

2. The basins are all made of pots with good ventilation and low price. Large-scale production can also be used in hard plastic basins, beautiful and convenient, and convenient for transportation. It is used by foreign and domestic large enterprises. The roots of Rhododendron are shallow and the expansion is slow. The cultivation should use small pots as much as possible to avoid uncontrolled watering and unfavorable growth.

3. Commonly used black soil, commonly known as orchid mud, can also be used peat soil, Huangshan soil, humus soil, pine needle soil, sawed sawdust, etc., PH5 ~ PH6.5, transparent drainage, rich in humus, can be.

4. The upper basin is generally carried out when the house is out in the spring or when it enters the house in the autumn. The bottom of the basin is filled with the drainage layer of coarse-grained soil, and the upper basin is placed in the shade for a few days, and then moved to the appropriate position. The number of pots changed during seedling period is once every 1 to 2 years. After 10 years, it can be changed once every 3 to 5 years. As long as there is no problem with the old tree, it can be changed for many years.

5. Watering should be based on the weather conditions, plant size, dry and wet soil, growth and development needs, flexible control. The water quality should be alkaline. If you use tap water to water the flowers, it is best to store them in the tank for 1-2 days. The water temperature should be close to the potting soil temperature. After November, the temperature will drop, the amount of water required will be small, and it will not be a problem if the room is not warmed for 3 to 5 days. After the end of February, it is necessary to increase the amount of watering appropriately. From March to June, the flowering tips are large, the water demand is large, and the daily watering is done once a day. When it is insufficient, it is necessary to replenish water in the evening. During the rainy season, it is rainy day, and the water should be poured into the side basin in time. During the hot season from July to August, it is necessary to carry along with the dry, in the afternoon and evening to spray water on the ground and leaves, to cool down and humidify. The weather is still hot from September to October, and watering cannot be slow.

6. Fertilization Xiqiao requires thin fertilizer and diligent application. Commonly used fertilizers are grass juice water, fish water, and rapeseed cake. The grass juice is made of tender grass and vegetable leaves, which can be poured into water. The fish gills are mixed with water 10 times, sealed and fermented for more than half a year, and should be watered when applied. The concentration is preferably 3% to 5%. This fertilizer is rich in phosphorus, which can make the leaves bright, but the next day should be washed once with water. Rapeseed cake is a comprehensive fertilizer, which should be cooked for several months and applied with water. Large-scale production of azalea potted flowers, compound fertilizer or slow-applying fertilizer can be used, one or two times a year.

7. Shading Xiqiao should be shaded from May to November. The height of the shed is 2 meters. The light transmittance of the shade net is 20% to 30%.

8. After pruning the seedlings within 2 to 4 years, in order to accelerate the formation of the skeleton, the flower buds are often removed, and the hearts are often picked up to promote the germination of the lateral branches. After growing into large trees, the branches are mainly cut off, weak schools and branches of disordered trees. Mainly based on sparse.

9. Flowering management and flowering control Xiqiao is placed indoors during flowering and is not exposed to the sun and rain, and can last for one month. If the indoor ventilation is poor, it should not be put on for a long time, and should be exchanged in one or two weeks. After flower bud differentiation of rhododendron, it can be flowered in 20C environment for about 2 weeks, but the varieties vary greatly.
