Capsule yellow-brown, 3-4 mm long.
Flowers bloom in April. Ecological habit: I like warm to high temperature and plenty of sunshine.
Pruning can be done after defoliation in winter. Drought-resistant, water-resistant and moisture-resistant, it is a wet-born positive tree species.
I like to be born in wetlands on both sides of the river bank, and I won't die if I am flooded for a short time. High dry land and calcareous soil can also adapt.
Germination early, defoliation late, growth fast, but not as cold-resistant as Salix matsudana. Short life span, aging gradually after 30 years.
Propagation and cultivation: Cutting propagation is often used to maintain the excellent characteristics of the mother tree. Cutting propagation is the main method, and sowing can also be used to raise seedlings.
Cuttings are carried out in early spring. Select excellent plants with fast growth and few pests and diseases as cutting mother trees. Before germination, 2-3-year-old branches were cut and cut into cuttings with the length of 15- 17 cm. The row spacing of cutting seedlings is 20 * 30cm. After cutting, fully water the soil, often keep the soil moist, wipe the buds and weed in time, and topdressing for 3-4 times after rooting. The seedlings are vulnerable to weevils, aphids and willow beetles.
Sowing and seedling-raising seeds are harvested in April and sown at the time of collection. The 1000-grain weight is 0.4 g, the germination rate is 70-80%, the sowing amount per mu is about 0.25 kg, and the seedling height in that year is 80- 100 cm.
Transplanting should be done after defoliation in winter and before bud germination in early spring of the following year. After planting, fully water and erect pillars.

2. How to manage willow trees
Willow, Salix, and Sophora japonica are common in life. Perhaps it is because of its commonness that it proves that people prefer to plant willows. Therefore, the management of willow in the later period is also very important. Let's share the knowledge of willow.
Be sure to pay attention to the management of willow in the later period, such as watering and fertilizing willow. These are very important steps, and special attention should be paid to the prevention and control of pests and diseases. It is best to prevent this situation in advance. Especially in winter, we must strengthen the warmth of willow trees.
What kind of warm-keeping methods do people use? White lime water is recommended by Wang Miao to keep warm. This method is also widely used. it wont hurt you to try it Pay attention to all the points mentioned above. Of course, not only willows should do this, but also elms, locust trees and fast-growing willows can do the same.
Wang seedling planting base in Hebei Province is the largest seedling planting base in North China, with many years of planting experience. Moreover, the geographical location is convenient for transportation and the environment is good. The survival rate of seedlings such as elm, willow and Sophora japonica planted is high, and the price of weeping willow is favorable. We have contracted a large number of purple plum wholesale, which has won unanimous praise from new and old customers. Welcome to visit and buy.
3. What are the characteristics of willow?
The characteristics of willow are as follows:
1. popularization:
Willow is a very common tree species, which can be seen almost everywhere in daily life. It has the characteristics of "common people": ordinary, simple and not luxurious, but it is flourishing and full of vitality.
2. full of energy:
As the saying goes, "if you have a heart, you can't plant flowers." Willow represents exuberant vitality-it can grow from a humble branch into a towering tree without deliberate care-isn't this what our educational philosophy matches? Believe in children's self-development ability and give them space to explore and develop themselves. We are their assistants on the road to growth, not the givers.
3. Ability to adapt to the environment:
Willow trees can be seen almost anywhere in the country, town, south or north: by the river, by the road, in front of and behind the house. Willow has a strong adaptability to the environment, which is exactly the purpose of our education-we don't want children to be flowers in a greenhouse and know everything, but they can't adapt to society, but we hope that every child can live independently, stand on his own feet, be optimistic and cheerful, and make contributions to the family and society.
4. Easy-going and tough:
I'm afraid wicker is the most flexible branch. It moves with the wind, so it is easy. Therefore, wicker has become children's favorite toys: whip, wicker hat, wicker whistle … wicker is not a "strong" tree, but it has its own patience and persistence.
Willow, or willow, is a general term for willow plants. There are more than 400 species of Salix, which are common in cold regions and moist soils in temperate regions of the northern hemisphere.
Salix plants are easy to hybridize, and both natural hybridization and artificial hybridization are common. A famous example of ornamental plants is weeping willows, which is a hybrid of weeping willows from Bai Liu and China in Europe.
In ancient China, willow was regarded as a tree of military camp or a tree accompanied by hermits. Because of its strong vitality and fast growth, willow is often planted around military camps as a barrier. Therefore, the military camp is also called Liu Ying. Today, the name of Liucheng is all over China.
Weeping willows are loved by ancient hermits because of their lush. Ji Kang, one of the seven sages of bamboo forest in the Western Jin Dynasty, was both a hermit and a rebel. In summer, he likes to put water around the big willow trees in the yard, and then squat down in the shade to cast swords. Zhong Hui, a captain of Li Si, visited him politely, but he was still immersed in smelting and ignoring him. Later, it was framed by Zhonghui organization.
Liu Ye is the object that many poets love to quote, such as The Biography of Mr. Wuliu written by Tao Yuanming, a poet in the Eastern Jin Dynasty, to show his ambition. Li Bai in the Tang Dynasty and Lu Fangweng in the Song Dynasty both had poems related to willows.
