There's a plant in the heat of summer that blooms undauntedly. It's violet. And the colours of the dust add to the sight of shin in the summer。
Violet is a chrysanthemum of chrysanthemum leaves or little chombers, also called 100 days of red, full of red, itch trees, etc. It is called "100-day red" because it has a long flowering period, and from june to september it has been open for hundreds of days, and "who spends a hundred days, and the six-monthly flowering of the verbs" is a compliment. And the alias "the itch tree" is the result of the smooth, light touch of the purple tree's trunk, and the twitching of its leaves as if it were itching。
Purple flowers have a deep cultural foundation in china. Our ancient people have divided the sky into three star regions, the forbidden planet, and the city of tiancheng, the core of which is the purple microstar, the "beidou star", which is considered the "ocean star". In the year of the founding of tang, the ministry of reformed studies and research is the department of ultra-violent, the order of the ministry of foreign affairs and culture, and it is grown in large numbers in the premises. At the time, there was a rumour that “black flowers were planted in front of the door, and the family was rich and flourishing”, which made them “rich flowers”。
The purple flowers are rich in colours, such as purple, neptunium, red, light red, dark powder and white. Its petals are wrinkled and thin, and the breeze is passing, and its flowers shake gently as a dancing fairy. In the greening of the garden, violet is an excellent flower-looking, dry-tree species that can be planted on their own, planted or made into a basin view. With its rich colour and months of flowering, it occupies a unique place in the summer urban landscape。
As one of the most important flowers in the summer, the maintenance of the purple is essential for its growth and beauty. In the spring, water is poured in the bud in combination with the planting of pine fields and the application of balanced complex fertilizers. At this point, if there are too many sproutings, it is necessary to leave each branch with three to five large sprouts in the right direction, all the rest of which will be removed to ensure a concentrated supply of nutrients. In the summer heat, water needs to be replenished in a timely manner in order to avoid the damage to plants caused by watering during high temperatures. In mid-august, the second flower for the national day was to be cut with controlled flowers, followed by high levels of potassium phosphorus fertilizer to facilitate thawing. After the flower (early august), the thin and sick branches are trimmed, then cut off the flowers and shrink the branches back to the second bud under the flower handle. After the second flower, it is also important to cut the flowers in time. Different cut-off times have an impact on the timing of the second flowering period of the violet, which, depending on the temperature and variety of the year, can generally reach a second flowering period of 25 to 35 days; during winter cut-off, two-thirds of the year-long branches have been trimmed, prompting the second year to grow strong, while cutting out the long branches, dry branches, down branches, disease branches, fibrous branches and internal branches, maintaining the beauty of trees and concentration of nutrients. When trimming, care is taken to retain and nurture branches in various directions, so that, in keeping with the requirements of growing space, the outer contours can form a whole arc, thus ensuring consistency in the appearance and growth of each branch, and, in the end, almost at the same time, each bud enters a flowering period, thus producing a similar view of the umbrella。
Pest and pest control is also the focus of purple conservation. The most common pests in the shanghai region are aphids, violet elephants, purple velvet, powdery and coal pollution. Timely treatment is required according to the pattern of disease and pest occurrence, such as regular inspections, which, if aphids are found, can be treated with sprays such as aphids, and, for vervamins, with pyrophos during infestation. Through integrated shear conservation measures, violet continues to shine in the shanghai region, adding glamour to the urban landscape。
At the shanghai botanical garden, there is a violet in the four seasons of the greenhouses, which, by carefully trimmed, forms a wide and slightly arc-shaped whole-faced, flowering like a large umbrella, attracts a large number of tourists to view. It's in the basin park. It's the violet view tree. A hundred years of southern violet is on fire, and the white flowers bring light. The strong and powerful rods of the tails of the north, which show a unique fragrance, are the hot spots of the garden, and welcome to take pictures of this beautiful flower, to feel its charm, and to leave the best memories of the summer
