Seven links in cultivation and Management of planting Rose

1. Site selection for garden construction: mountain areas should make full use of Weir and soil slope, which can not only increase economic benefits, but also consolidate soil and protect Weir and prevent soil erosion. A special rose garden should be built on the plain. However, no matter in the mountains or plains, do not plant on the sticky and heavy waterlogged land.

2. Soil treatment: soil disinfection is carried out before planting, mainly by steam disinfection, and can be fumigated with chloropicrin unconditionally. After chloropicrin fumigation, it should be turned deeply for many times to avoid drug damage affecting the development of plant roots. Then apply 20 cm thick farm manure for ploughing. The plain land is formed into a high border with a width of 200 cm and a height of 15-20 cm.

3. Planting: the planting row spacing is 2-2.5 meters, the plant spacing is 1-1.5 meters, and the plant row spacing can be increased appropriately in the plain. Dig the planting pit (60 cm in length, width and depth), put it into the seedlings, fill the soil firmly and water it.

4. Fertilization: fertilization can be carried out in two stages. Once in late autumn, combined with deep ploughing, 3000-3300 kg of farm manure per mu was applied; the other time, 5-25 kg of diammonium phosphate or other compound fertilizer was applied per mu after flowering.

5. Pruning: roses have strong sprouting ability. If they are not pruned in time, the branches will grow thin and withered because of the closeness of the plants. Pruning should be carried out according to plant age, growth status, fertilizer and water and management conditions, and the principle of thinning mainly and cutting short should be adopted, so that the old branches are not old, many branches are not dense, ventilated and transparent. The old branches of more than 5 years should be thinned in time to support the growth of new branches. For roses whose growth is weak and basically lose their ability to blossom, they can be re-cut and promote the growth of new branches.

6. pest control: the main diseases of roses are rust, powdery mildew and brown spot. The prevention and control of rust can remove the disease buds and bury them deeply. Before and during the onset of rust, powdery mildew and brown spot, trimethoprim, trimethoprim or chlorothalonil were sprayed once a month, which had a good effect on preventing the spread of the disease. The main pests of roses are beetles, big bag moth, red spiders, aphids, scale insects, longicorn beetles and so on. Beetles and pouch moths mainly harm the young shoots and leaves of roses, which can be sprayed with phoxim and enemy during the occurrence period; red spiders, aphids and scale insects mainly feed on rose juice, causing growth weakness, and can be controlled by spraying internal insecticides such as dimethoate and monocrotophos; longicorn beetles are destructive pests, so their adults should be killed and the nectar plants that absorb nutrients should be eliminated to inhibit their occurrence.

7. Harvest: the harvest time of roses is different, and there is a great difference in yield and quality. Usually the rose bud should be harvested before opening, that is, the harvest is best when the longitudinal diameter of the bud is 3 times of the calyx, the yield decreases prematurely, and the late blooming affects the quality. In the middle of the flowering period, strong and full buds are selected, and the petals of other weak buds are picked after they are fully opened. Flowers that bloom sporadically at other times also wait for full bloom to pick petals.
