Northern cultivation of azaleas

In recent years, azaleas have become more common in northern regions. First, reproductive technology: 1. Cutting propagation: Generally, the most robust semi-lignified shoots are cut from May to June, about 5-8 cm long, and the lower leaves are cut off, leaving 2-3 leaves of the parietal lobe as cuttings. The base of the cuttings is preferably soaked with a solution of indole butyric acid or ABT rooting powder, and the cuttings are then placed in a loose, air permeable, humus-rich acidic soil. The temperature is maintained at 20-25 degrees Celsius, shaded and often spray moisturized. 2. Twig splicing: For rare species that are difficult to survive, such as Xijing, cut the twigs for about 3-4 centimeters for the scion, and use a knife to cut the base into wedges. Use ranunculus for rootstocks and use tender twigs. Then use a plastic film under the shady shelf and use a plastic bag to cover the skin with the scion and the rootstock. Second, fertilizer and water management: Due to the more acidic soil in the north, so basin soil must be mixed with humus soil such as decomposed pine needles. When applying fertilizers, follow the principle of timely, appropriate, and diligent application. A phosphate fertilizer can be topdressed once a month in spring. After flowering, 1-2 times of nitrogen-phosphorus-based compound fertilizers were applied, and during the period of 9-10 months, 1-2 phosphate fertilizers were applied during the buds. Azaleas prefer a cool, moist environment. The climate in the north is dry and should be watered and sprayed in time to maintain high air humidity. Watering plants should be treated with fertilizer and rainwater. For example, use common water to add a small amount of ferrous sulfate and vinegar, or cut the watermelon or tomato into small pieces. This has a good effect on improving the quality of soil and flowers. Third, the plastic trim: To accelerate the formation of plants, azalea often through the heart to trigger new branches. For the flowers clustering, affect the flower shape can be prematurely bud. Pruning is generally carried out in the spring after flowering and in autumn. Cut dead branches, oblique branches, leggy branches, diseased shoots and some cross branches. Fourth, flowering control: Du Fu in the autumn flower bud differentiation, through refrigeration and heating treatment, you can artificially control buds. To enable the cuckoo to flower in advance, it can be moved to the greenhouse for cultivation, controlled at 20-25 degrees Celsius, and maintained at a relative humidity of over 80%. It can bloom after one and a half months. To delay the flowering of the azaleas, the azaleas that form the buds can be kept at a low temperature, keeping the temperature at 2-4 degrees Celsius, watering when the plants are dry, and moving outdoors in summer and autumn, and flowering after 2 weeks.
