The rose is a deciduous shrub of the Rosaceae. Its flowers can be extracted from essential oils, tea, wine, medicine, food, and sauces. The fruit is ripe after edible. It is an important raw material for extracting vitamin C. It is an ornamental, medicinal and gourmet food. Flowers and trees. After several decades of intensive research, researchers at the Institute of Rose Research in Shandong Pingyin succeeded in breeding a new species of purple twig rose, named after its bright reddish-purple after the frosted branches were harvested. This was Pingyin rose, which was hybridized in 1980. It was selected as an excellent single plant in 1983 and it was planted in a hybrid garden in 1987. After more than ten years of observation, the purple twig rose shows good growth traits, large flowers, pure aroma, multiple flowering and other good traits, and various traits are very stable. Because of its great differences in biological properties from other rose species, rose experts have designated it as a separate subspecies of rose species. According to the color of the petal, the purple branch is divided into three varieties: purple, pink and pink. The pink one has double and single petals. At present, a large area is planted with pink purple rose branches. The purple rose bud has a long flowering period. It blooms from the end of April to the fallen leaves, enjoys flowers in the summer and autumn, sees fruit in autumn and winter, and enjoys the winter and spring. It can be enjoyed in four seasons. The purple branch rose has a more open shape. The culm is as high as 2 meters. The pods are 20-140 centimeters in diameter. The branches are finer. Hammer hurried?

Purple rose starts to sprout in mid-February from normal level, leaves in mid-March, buds in early April, flowers in late April, full bloom in early May, late flower in mid-May, and second full bloom in mid-to-late June. After that, it can continue to flower every month. The peak flowering period is from May to June. The purple branch rose has a similar flowering habit to the rose, and has the characteristics of flowering when the branches are pulled. Therefore, the key to cultivation is to promote new branches. Purple rose buds are resistant to cold (-18°C), drought tolerant, thin and resistant to pruning, and can grow in slightly acidic and slightly alkaline soils, but fertile slightly alkaline soils are preferred. Strong habits, hi light, strong adaptability, rapid growth, new shoots, strong growth, multiple flowering characteristics of obvious performance, but let it grow naturally, five or six years after only two flowers in May and June, multiple flowering The characteristics are almost lost. Therefore, pruning should be based on heavy cutting, short cuts, sparse 4 years old branches and thin branches, pests and branches, to prevent bald upper part of the shoots, in order to promote multiple branches of new shoots. Fertilization should be dominated by nitrogen fertilizer, combined use of nitrogen, phosphorus and potassium, especially organic fertilizer, in order to promote new shoots, display its multiple flowering characteristics. After 4 years of colonization, the purple rose buds are less susceptible because of their strong growth, and leaves more than 5 years old are susceptible to black spot, causing early defoliation. Control method is the first time after flowering, spray once every two weeks times Bordeaux mixture 100 times liquid, even spray 3-4 times; if you have been sick, you can first spray 50% carbendazim 600 times. Zizhi rose is propagated by cutting or grafting methods. Because of its strong rooting ability, the simple and quick cutting method is often used. Spring, summer, autumn and autumn can be inserted, and conditions can also be winter. Hardwood cuttings are combined with pruning after falling leaves in autumn and before budding in spring. The bright purple-red branches with short internodes and axillary buds are cut and cut into small segments of 5-20 cm in length, inserted loose and fertile. In the soil, the plant spacing is 10 centimeters in length, 0 centimeters in the core, and 0 centimeters in the core. It is practical, irrigated with water, keeps the soil moist, and survives when the ground temperature rises. The survival rate is 80%. Twig cuttings should be carried out in June-August. Cut short, vigorously growing, full-vein buds, and semi-lignified branches without pests and diseases. Cut into 8-10 cm long sections. Cut on the upper side and cut obliquely on the lower side. The upper 2 compound leaves, each compound leaves retain 2-4 leaflets, insert with 3% high manganese potassium solution to eliminate toxic sand or vermiculite, spacing 5 cm ~ 5 cm. Spray water after inserting, maintain the temperature and humidity according to the weather changes, keep the leaves without losing water. After 15 days of rooting, 35 days of root development can be completely transplanted into soil with sufficient water and fertilizer, and the survival rate is more than 90%. If management is strengthened, it can bloom in May of the following year, and it can be as high as 1 meter in the autumn. The grafting of the purple twig rose is selected as the rootstock with the same roots as the roots of the same genus and the growing season. Select the sprigs that are robust, free of pests and diseases, full of buds, and purple-brown shoots as the scion, and then use sprouts or xylem buds to save time and the survival rate is high. When the grafted purple rose grows up, the clusters are inverted conical and the roots are free from sprouting, which is easy to manage and has a longer life than the cutting seedlings.
Auxiliaries (Additives) are defined in medicine as excipients and additives used in the production of drugs and prescriptions, that is, all materials except the main active ingredients of drugs, are important components of pharmaceutical preparations. In industrial production, auxiliary chemicals added to improve the production process, improve product quality and yield, or to endow the product with a specific application performance. It is also called additive. However, as an important component of the product matrix, large doses of additives, which have a significant impact on the shape, structure and performance of the product, are generally not included in the category of additives.
