First, the planting environment of cold-resistant rose has a strong adaptability to the cold-season rose, and the environment is sunny, leeward and air circulation. The suitable temperature for growth is 8-25°C, the optimum relative humidity for growth is 75-80%, and it can withstand -35°C low temperature in winter. The cold-tolerant roses are suitable for planting greenery or potted plants. They are fertile and loose, have good drainage and ventilation, and are rich in humus-rich loam or light clay.
Second, cultivation technology
1. Site preparation: Planting in nursery or greenery, first leveling up the well-turned land, applying sufficient base fertilizer, and using the farmyard fertilizer as a predominant fertilizer. Add a small amount of diammonium as appropriate. The row spacing for planting roses is generally 40 centimeters and 50 centimeters. In order to facilitate day-to-day management, each plant should be planted with two kinds of behaviors, with a width of 40 cm, and about 3,400 plants per acre.
2, pruning and disinfection of seedlings: Rose is best to dig with the planting, before planting, the seedlings once trimmed, cut off diseased branches, dry branches, weak branches and damage roots and long roots. The pruned roses were soaked with ABT3 rooting powder for 0.5-2 hours and then sprayed with chlorothalonil or carbendazim wettable powder 600 times for 1-2 times.
3. Planting: Put the plants into the hole when planting, lightly raise, carry out the soil, and water, so that the soil is fully wetted, and finally the soil inside the hole is full and practical.
Third, daily management
1. Irrigation: The root soil of the Chinese rose should be kept moist. The number and time of watering should be controlled according to the climatic conditions. The principle of not pouring or pouring should be adhered to. The best time to water is to water in the early morning or near late afternoon.
2. Fertilization: In the case of proper fertilization, the Chinese rose will bloom beautifully and it will also enhance the plant's ability to resist diseases, pests, and cold-resistance. Before the germination of the early spring rose, an inorganic fertilizer should be applied to promote early growth. In cold regions, one and a half months before the autumn frost, spraying with potassium dihydrogen phosphate at a concentration of 1.5-3 ppm for fine foliar spraying can promote rose branching and improve cold resistance. During the growing season, top dressing is performed once a month, so that thin fertilizers are applied more frequently and the fertility is even. Apply 0.15-0.1 kg of compound fertilizer per square meter.
3. Pruning: The growth period of the Chinese rose from spring budding to dormancy in early winter. Before and after each flowering period, pruning should be carried out properly. For newly planted young plants, buds should be picked in time to promote the accumulation of buds. Raise branches and send flowers. Every time after the flowers are cut off, they are cut off. In the pruning of the growing season, in order to prevent the plants from sprouting in the inappropriate position, buds in other parts of the shoots should also be promptly removed. For the robust tree rose, in addition to cutting away dead branches, diseased branches, and injured branches during each pruning process, some thin, weak, messy and overcrowded side branches should be trimmed to make the whole The plants form an inverted umbrella. The winter shears are mainly strong shears, and they are all cut at 3-6 cm from the base, leaving only about 10 buds at the base of the main branch.
IV. Pest Control
1. Powdery mildew: A layer of white powder appears on the lesions on the back of the leaves, and the whole leaf is covered with a layer of white powder. Control methods: (1) Strengthen cultivation management, increase phosphorus and potassium fertilizers appropriately, and increase resistance to disease. Improve ventilation and light transmission between plants. (2) Reduce the source of infection, cut sick branches, diseased shoots and diseased leaves. (3) At the beginning of the disease, 3500 times of powder can be sprayed, or 15% of triadimefon can be used as 1000 times of liquid, sprayed once every 7 days, and even sprayed 3-4 times, the treatment effect is better.
2. Melasma: Rose black spot, also known as brown spot, usually occurs on the surface of the leaves. Control methods: (1) Clean the leaves at any time, remove the diseased leaves, and thoroughly remove them after the fall to reduce the source of infection. (2) Before germination in early spring, spray 5 degrees lime sulfur to eradicate germs. At the beginning of the disease, 75% chlorothalonil 500 times solution or 72% Kelu wettable powder 600 times solution was sprayed. These agents can be used alternately, sprayed once every 5-7 days, and sprayed 2-3 times.
3. Botrytis cinerea: Botrytis cinerea at the margins and tip of leaves occurs as water-stained light brown spots. Control methods: (1) eliminate diseased parts in time, remove stray flowers, and reduce the source of infection. (2) planting should not be too dense, should be air and light. (3) Prevention with 70% dexamethasone zinc 500 times spray, 64% antiviral WP 500 times, 75% chlorothalonil 500 times, spray once every 7-10 days, and even spray 2 -3 times.
4. Oriental scarab: Prevention methods: (1) According to its habit of biting can be organized manually captured. (2) Plant cabbage in the trenches ahead of time and spray Wanling on cabbage to kill them. (3) Spray the ground with 50% phoxim 1000 times liquid at dusk to kill the underground pests.
