Ventilation to the sun, good irrigation and drainage conditions, moderately alkaline or slightly alkaline soil is the most suitable, and slightly acidic soil can also be used. However, no matter in mountainous areas or plains, it is forbidden to plant on sticky and stagnant land.
Second, soil treatment.
Disinfect the soil before planting, mainly steam disinfection, and plough deeply for many times to avoid phytotoxicity affecting the development of plant roots. Then apply 20 cm thick farmyard manure for ploughing. In the plain, the border is 200 cm wide and 15-20 cm high.
Third, colonization.
The planting row spacing is 2-2.5m, and the plant spacing is1-1.5m. The plant spacing can be appropriately increased in plain land. Dig a planting pit (60 cm long, 60 cm wide and 60 cm deep), put in the seedlings, fill the soil and water it.
Fourth, fertilization.
Fertilization can be carried out in two stages. Once at the end of autumn, combined with deep ploughing, apply 3000-3300 kg of farmyard manure per mu; Another time, after flowering, 5-25 kilograms of diammonium phosphate or other compound fertilizers were applied per mu with loosening soil.
Verb (short for verb) pruning
Pruning should be carried out according to plant age, growth condition, fertilizer and water and management conditions, with thinning as the main method and short cutting as the supplement, so as to achieve the purpose of not aging old branches, not dense branches, ventilation and light transmission. Old branches over 5 years old should be thinned in time to support the growth of new branches.
Extended data:
Rose grafting:
1, budding method. Every 5-9 days, plump buds are selected from the improved parent plants, and 1-2 buds are grafted on the Tang white jade or rose rootstock, or one bud is grafted on the long branch of the rootstock every 8- 10 cm. After grafting, the branch with a grafted bud is cut into segments and inserted into a sand bed or container like a general cutting method.
2. Grafting method. Every spring, the rootstocks of Rose and Tang Baiyu can be grafted with improved branches by cutting, tongue grafting and abdomen grafting.
3. Rooting method. In winter and spring, when the rose is dormant, the scion will be attached to the indoor rose or one of the Tang Baiyu, tied and tied at the bottom, and kept moist in a medium-temperature greenhouse, and then put into a pot or planted after the joint is healed.
