There are many monsoons in spring and autumn, and it is hot and rainy in summer. The urban area occupies more than 20 square kilometers, of which the green area accounts for 4 square kilometers. In this environment, in order to further improve the city appearance, optimize the road network structure of xinzheng city, improve the road traffic function, enhance the carrying capacity of the city, better beautify the city image, and improve the city grade and investment environment. Because Chinese rose has strong adaptability, cold tolerance and drought tolerance. The requirements for soil are not strict. It also has the characteristics of continuous flowering. It is an evergreen or deciduous shrub with rich colors and fragrant flowers. Known as the "queen" in flowers. Chinese rose, also known as "moon red", "longevity flower" and "fighting blood red", is one of the most popular and widely cultivated flowers in Xinzheng. In Xinhua Road, Zhenghan Road, Xú Zhēng Road, Cishan Road, Liuyuan, Zhengfeng Garden, Lotus Garden, Jujube Garden, Moon Bay, Yanhuang Square, Tengfei Turntable and other places, different areas of Chinese rose were planted. This is very important and necessary to improve the overall quality of society. 1 Chinese rose cultivation techniques Spring is the season when Chinese rose is loose in a large area, and it is also the best time for Chinese rose fertilization. Fertilizing rose when there is water can not only enhance the loose ventilation performance of soil, but also promote the normal growth of root system. At the same time, Chinese rose aphids mostly occur in spring, and it is very effective to prepare 10% imidacloprid 20g/ mu and 4.5% cypermethrin 45ml/ mu with a big water wheel. One drug is only used once, and the next drug is replaced when the control effect is not good, so as to find and prevent it in time. Weeds grow in the longitudinal season of summer. At this time, it is necessary to clean up the weeds every half month, so as not to affect the growth of Chinese rose, and at the same time, protect its water. Due to the large number of flowering times of Chinese rose, it is necessary to supply sufficient nutrients and water to ensure vigorous growth. In summer, evaporation is large, consumption is large, and it grows rapidly. Apply thin fertilizer every 10 day in flowering period to make the plants flourish and break the dormant state of Chinese rose in summer. You should also spray more water, preferably once in the morning and once in the afternoon, to create a humid environment and promote the growth of flowers and leaves. After the first batch of flowers opens in May, cut off the middle branches and leave 3 ~ 4 buds on the branches; Cut the weak branches again, leaving 1 to 2 buds; Strong branches are lightly cut, leaving 5 buds and appropriately inhibiting growth. The second flowering should be lightly cut, only the residual flowers should be cut off at the top of the second leaf, and the axillary buds of the second leaf should be kept. This kind of bud has the best growth and development advantage, occupying the dominant position of the whole plant. Cutting off this bud will affect the next flowering period, the quality of flowers and the growth of plants. Rose sawfly mostly occurs in May-August, and it is controlled in the waterwheel with 480g/L of Lexben 1000 times solution in mid-May. Chinese rose scale insects mostly occur in August-165438+1October, which is often judged as a disease and should be paid attention to. Drug control can choose 40% fast culling 3000 times solution for prevention and treatment. Pruning after flowering in early autumn (the third batch of flowers) adopts intermediate cutting, leaving 3-4 buds on each branch. In order to take care of the balance of plant shape, you can also retreat to the last batch of flowering branches and trim them up and down. Cut off overlapping branches, cross branches, too dense branches, long branches, etc. , in order to facilitate ventilation and light transmission and plant shape symmetry. In addition, it is not advisable to leave too many flowers in each crop, otherwise the nutrients are too scattered and the flowers are small, which will affect the flowering of the next crop. In winter, the Chinese rose is dormant and needs pruning once a year: according to the root of 10 cm, leave a few thick branches. The common diseases of rose mainly include black spot, powdery mildew and branch blight. The occurrence of black spot disease has a great relationship with the environment. Residual branches, rotten leaves and dead flowers are the soil where germs breed, and high humidity and fog are the causes of the disease. 75% chlorothalonil powder mixed with 1 1,000 times solution can prevent and treat 1 time at the initial stage, with an interval of half a month 1-2 times, which can effectively prevent and treat. Powdery mildew often occurs in places with high planting density, poor ventilation and light transmission, and more shade. It can be prevented and eliminated by spraying 1000 times liquid twice 15% fenxiuning powder. Branch blight is mostly induced by wound infection such as poor nursing and excessive pruning. Strengthening nursing and pruning in sunny days can reduce the incidence rate, and 500 times of 50% bacteria-returning powder can be prevented and treated. The use of Chinese rose in February The roots, leaves and flowers of Chinese rose can be used as medicine, which has the effects of promoting blood circulation, detoxicating and reducing swelling. Fragrant varieties can also be extracted and eaten. Chinese rose can treat common gynecological diseases, and its remedies and prescriptions are also very effective. In addition, women often use rose petals soaked in water as tea, or drink them in other bodybuilding teas, which can also promote blood circulation and beauty beauty, and make people stay young for a long time. More importantly, it can beautify the city, bring people a green world and make people feel relaxed and happy. Conclusion In a word, Chinese rose has strong adaptability and is easy to breed and manage. Roots, leaves and flowers can also be used as Chinese herbal medicines, which can beautify the environment and give people a fresh and pleasant feeling.
