The United States is a genus of deciduous vines of the family Asteraceae. When it enters the summer, it will draw a cluster of orange-red flowers on the branchlets that year, and will be the first to open. It will be even more impressive to see the velvet vines. Most of its leaflets are 11-13 pieces. The corolla is dark orange, and the corrugated tube has no edges. Its thickness is thick and smooth, and its flowering is luxuriant. The flowering period is widely cultivated throughout China in October. The flowers of the genus Campsis, which belong to the American Ling Xiao, contain 7-11 leaflets, most of which are 9. The flowers are slightly larger, the funnel-shaped bell-shaped bell-shaped and the upper five ribs are the characteristics of this flower. The United States of America Ling Xiao originates in North America, hi warm, good sunshine, with many clusters of aerial roots, climbing ability, can climb in the trees, the wall grows upward. It is relatively hardy and does not require strict soil requirements. It can grow strong and strong in moist and fertile soil. The breeding of American crickets can use cuttings, ramets and sowing. The cutting method is to cut the roots of the aerial roots in the growing season to cut the seedlings, pay attention to shade, moisturize, and it is easy to take root and survive. In early spring, cuttings of 20 cm in annual branches can also be cut. About 2 months after the rooting. In addition, root cuttings that are yellowed in their soil are also prone to rooting. In the early spring, pick up the underground root, cut it into 10 cm long pieces, bury it in the earth, and pour water. A large number of seedlings sprout from the underground root system in the United States. Until March-April, dig it up and plant it. The method of using the squeezing bar is generally performed from May to June. If the method of squeezing the bar is correct, each section can take root. Because American Ling has a strong ability to climb, flower growers often make flower racks or materials for vertical climbing. Climbing on the balcony or in the west to climb the wall can not only beautify the environment, but also can block the intense summer sun and reduce the indoor temperature. This flower is also suitable for ornamental viewing in pots. In order to obtain a good ornamental effect, bamboo or other materials can be used to construct a variety of figures or animal shapes, and then the dendrite needs to be supported, guided and fixed during the growth process to make it suitable for humans. Willing to climb, you can grow into a beautiful body. For natural drape culture, let the plants hang down from high places and grow into blue-leaved neroli orange flowers that sway with the wind and have no taste. The United States Ling stay daily maintenance is relatively simple. If there is a lot of flowering, let it receive more sunlight. During the growth and flowering period, apply 20% of the cake water every month. Watering should master the principle of asking the Pavilion to ask for wetness. After the first batch of flowers in summer, the branches can be recut, leaving only one or two knots to make them sprout new. After pruning, add the compound fertilizer 2-3 times to achieve the purpose of flowering. Due to the large pith in the American twigs, the old branches tend to be hollow. After winter, there will be a lot of dead branches that should be trimmed before sprouting in the spring. And sparsely cut the dense branches. However, the branches are generally not cropped because their flower buds are mainly distributed on the top of the last year's shoots. Usually only after the flowering of the strong growth techniques, promote secondary flowers or cultivate new techniques for the next year to prepare for flowering. In addition, excessive old roots should be properly removed during the growing season. China Agricultural Network Editor
