Fenghua rose is a new rose variety successfully cultivated by means of hybridization. This breed passed the provincial appraisal in Shandong in 1998.
The range of suitable species Fenghua Rose is suitable for a wide geographical area and strong environmental adaptability. The annual average temperature can be planted in the regions from -7°C to +15°C, and the temperature is higher than 35°C, which is lower than -28°C and is vulnerable to freezing. .
Quality characteristics Fenghua rose can bloom many times a year, and the amount of flower production is the largest from May to June. The flower is extremely heavy, the flower color is purple, the flower does not reveal the core is like the peony flower, but also has the name of "peony rose". Single flower stem 8 cm, single flower weight more than 3 grams, the most weight up to 4.5 grams. Fenghua Rose has pure aroma, high oil yield and strong disease resistance. The arbors are not very open, they have obvious short branch traits, and they have strong three-dimensional flowering ability. Under general management conditions, the per mu flowers can reach 500 kg to 600 kg. Fenghua Rose is not only a fine tree species in mountainous areas, sand prevention, sand and soil conservation, but also a precious Chinese herbal medicine, an important raw material for the food industry and the spice industry, and a flower species commonly used in landscaping.
Planting methods Fenghua Rose is mainly grafted and planted, and it is used as a rootstock with cuttings and roses. It can be carried out in spring, summer and autumn. Grafting buds, branches, embryo graft, stigma and so on. Bud grafting has the advantages of economy of scion, easy healing, firm bonding, high survival rate, easy operation, high work efficiency, long period of accessibility, and non-viable connection. Fenghua Rose is the most suitable cultivation period before the fall of the leaves in autumn and before the sprouting in spring. It is the best period from the time of deciduous to freezing, and there are specific requirements for planting in different seasons. Spring planting: After the soil is thawed, the roses are planted in the early spring before sprouting. From late February to early March is the right time for spring planting. At this point, the rose root has begun to grow, the branches have not yet been sprouted on the ground, and the roots that have been damaged after transplanting are quickly healed and roots are easily healed. The survival rate of transplanting is high. The spring planting ends before the bud of the rose, otherwise it will affect the survival rate. Summer planting: The use of continuous rainy season in the rainy season, moist soil, and high humidity conditions to transplant roses. At this time, during the high temperature season, the roses are in the season of growing, and the evaporating amount of the leaves and leaves is large. In the summer planting, it is necessary to seize the favorable opportunity of continuous rain and rain in summer, otherwise the survival rate is low. This method is only applicable to the drought-prone mountains in winter and spring. Autumn planting: Planting time is generally from mid-October to early November. During this period, the rose leaves have begun to fall off, and nutrients have returned to the root system and nutrients have increased. However, due to the high ground temperature and the roots are still in the growing stage, the roots can be completely healed after transplanting, and the roots can be completely healed before winter and roots can be issued.
Fertilizer management is dominated by the application of nitrogen fertilizers, but also available nitrogen and phosphorus available fertilizers, such as urea, diammonium phosphate, etc., or the application of biological bacteria fertilizer, organic compound fertilizer, etc., to promote the growth of young leaves. From budding to flowering, if there is insufficient fertilizer, it will directly affect the yield and quality of the flowers, making them small and thin, low oil content, and causing a large number of buds. Experiments show that the spring application of bud fertilizer, the bud stage to the flowering period generally does not lack of fertilizer, if this period of soil drought, irrigation should be poured before the flowering period, flowering should not be watering, so as not to affect the flower.
Pest control diseases are rust, lime sulfur can be sprayed Baume 3 degrees to 4 degrees in the early spring before sprouting, growing season with 25% triadimefon 1000 times spraying according to the disease. There are more than pests with yellow beetles and rose three sawfly. Harm to the yellow multi-band longhorned beetle, should seize the pupation, emergence and climbed out during the pupal chamber prevention and treatment, carried out rhizosphere earth, weeding and renewal pruning, increase the resistance, and to protect the natural enemies wide beak bugs, ants and cricket; winter turning the soil around the plant, can destroy part of the three winter rose sawfly insect source, in early August, sawfly larvae can be sprayed 2.5% of young Decis 2000 times control.
