The seven links of rose cultivation management

1. Choose the land to build the garden: The mountain area should make full use of the mantle and the slope of the soil. This will not only increase the economic benefits, but also can protect the soil and prevent soil erosion. Plains should be built into a special rose garden. However, regardless of mountainous areas and plains, avoid planting on viscous water.

2. Soil treatment: Soil disinfection prior to planting is mainly based on steam disinfection. When it is unconditional, chloropicrin can be used for fumigation. After chlorpyrifos fumigation, it should be deep-frozen for several times to prevent the development of plant roots. Then apply 20 cm thick farmyard fertilizer and plow. The plain is 200 centimeters wide with a width of 15-20 centimeters.

3, planting: planting spacing of 2-2.5 meters, spacing of 1-1.5 meters, the plain can be increased spacing. Dig wells for planting (60 centimeters long, wide and deep) and put them in seedlings.

4, fertilization: fertilization can be divided into 2 times. One time at the end of autumn, in combination with deep turning, 3000-3300 kg of farmyard manure was applied per acre; another time after flowering, combined with loose soil, 5-25 kg of diammonium phosphate or other compound fertilizer was applied per acre.

5, pruning: rose sprouting power, if not timely pruning, often due to the closure of the branches caused by the growth of branches and thin dead. Pruning should be based on plant age, growth status, fertilizer and water management conditions, and adopt the principle of sparse shearing, supplemented by short cuts, to reach the old branch of the plant is not old, many branches are not dense, air and light. Old branches older than 5 years should be removed in time to support the growth of new branches. Roses that have lost their ability to blossom can be re-cut and promote new branches.

6. Pest control: The main diseases of roses are rust, powdery mildew, and brown spot. Prevention and treatment of rust can be removed from the buds. Spraying Triadimefon, Trichoderma, or Chlorothalonil once every two weeks before the onset of rust, powdery mildew, and brown spot, and has good effect on preventing the spread of disease. The main pests of roses are scarabs, big moths, red spiders, aphids, scale insects, and long-horned cows. The beetle and big moth mainly harm the young shoots and leaves of roses, and can spray phoxim and dinos during the occurrence; spider mites, aphids, and scale insects mainly suck rose juice, causing weak growth, and can spray dimethoate and monocrotophos. Insecticides such as insecticides are used to prevent and control; Celestine is a devastating pest, should kill its adult and remove its nutrient-absorbing nectar plants to inhibit its occurrence.

7. Harvest: Rose harvest time is different, yield and quality are quite different. Usually rose buds should be harvested before opening, ie when the buds are 3 times longer than the calyx, harvesting is best, premature yields are reduced, and flowers have been opened late to affect quality. During the flowering period, strong and full buds were selected for picking, and other fine buds were left open to pick the petals. Sporadic flower blooms at other times are still open after the petals are picked.
