Ecological habits like light, slightly tolerant of shade, slightly cold, afraid of waterlogging. It can overwinter in the open air in North China and Yanling, which requires warm and humid climate, loose and fertile sandy soil, good drainage, vigorous growth in acidic soil and poor growth in alkaline soil. The roots germinate vigorously. The landing part of the branch takes root easily.
Cutting is the most common propagation method. Select 1 annual branches, cut them into 15cm long, water the whole seedbed, and then cut them. You can also dry-cut, that is, cut the whole seedbed and then irrigate it with water. Cutting can be carried out from the middle of 10 of 65438 to the middle of 10 of 65438 or in spring. After rooting, it can be planted alone, divided into plants or propagated in layers.
Cultivation modeling: Yingchun forms flower buds on 1 annual branches and blooms in the next spring. Therefore, after the flowers wither every year, all the branches should be cut short to promote the growth of more lateral branches, increase the amount of flowers and strengthen the management of fertilizer and water.
In Gao Qian, water wax seedlings above DBH 2cm can be selected for spring cultivation, and abdominal grafting can be carried out at 1m or a certain height when budding in early spring. Take the branches of Jasminum nudiflorum as scions, with the length of 8- 10 cm, and carry out grafting. Then tie it tightly with a film, wrap it in a plastic bag, and gradually tear the bag after the branches survive, so that they can breathe freely to exercise seedlings, pick their hearts to promote side branches and cultivate crown shapes.

Related legends
There is a northeast and southwest ravine between Hutou Peak and Wansui Peak in Songshan Mountain. There are two millstones at the mouth of the ravine, and each millstone has a round pit, which looks like a horseshoe. Locals call these two pits "horseshoe pits" and these two stones "horseshoe stones". It is said that these are horseshoe prints left by Dayu when he was controlling water.
According to legend, what horse did Dayu ride? It has great strength, runs fast and can climb mountains and mountains. Dayu survived many difficulties with it. Shenma's ears are also very sensitive, which can distinguish the size of the wind and predict the climate change. Whenever there is a strong wind, it will stop its hoof, open its mouth, look at its owner and shout "Hui, Hui, Hui" three times.
It is said that Dayu treated floods in other places first, and put his hometown Songshan area last. After controlling the flood, Dayu is going to rest at home for a while, one is to make up for his wife's feelings, and the other is to educate him. Who knows that Dayu just stayed at home for three days when news came that the Yellow River at the northern foot of Songshan began to flood again, with huge waves and flooding in Yingze. If it breaks down, the consequences will be unimaginable.
Dayu once again bid farewell to Tushanyao. Tu Shanyao looked at Dayu anxiously, and said with distress and irritation, "Hey, you are so angry and left like this. Songshan is so big, can you fly with your wings? " The speaker has no intention, but the listener has intention. Dayu thought, yes, if you can fly over Songshan at once, you can save a lot of time.
Dayu touched Shenma's head and said, "Can you carry me to the northern foot of Songshan Mountain?" Who knows what nodded in agreement, Dayu was extremely happy. So Dayu rode out of the house.
Dayu wanted to see the water potential in Yingze first, so he came to Caoling Slope and was about to ride over Songshan Mountain. Unexpectedly, Shenma stopped and shouted "Hui, Hui, Hui". Soon, a strong wind blew, and the yellow sand in Xiaoyao Valley filled the sky, which fascinated Shenma's eyes. Dayu had to turn his horse's head and retreat. After the wind stopped, Dayu got on his horse again and prepared to leap over Songshan Mountain. Who knows the horse stopped again and shouted "Hui, Hui, Hui". Dayu saw the fog rolling in the western world, and the fog wrapped Shaoshi Mountain at once, and it was foggy for a while, so that God could not see clearly the east, west, north and south, and Dayu had to endure it.
After waiting for a long time, the fog finally cleared away. As the saying goes, things are only three. Dayu patted the horse's head and said, "Come on, you must fly there this time!" " Shenma understood the master's meaning, nodded and looked at the terrain carefully. He found two huge stones in the ravine between Hutou Peak and Viva Peak. He immediately raised his neck and stepped on it with his front hoof. Dayu also held his breath and clung to the reins. Then Shenma stepped on the boulder with his front hoof, jumped up with all his strength, flew over Songshan Mountain and landed safely at the northern foot of Songshan Mountain.
Because the horse used too much force, a pair of front hooves kicked out two horseshoe-shaped nests on the boulder. Later, the masses called these two stones horseshoe stones and this ravine horseshoe ditch. winter jasmine
A long time ago, there was a flood on the ground, crops were flooded, houses collapsed and people had to gather at the top of the mountain. All day long, the world is chaotic, and even the spring and autumn seasons can't be distinguished.
At that time, the emperor called Shun, and Shun asked his minister Gun to lead people to control water. After several years of treatment, the water is getting bigger and bigger. Gun died, and his son Yu provoked the heavy burden of water control.
When Yu took people to find waterways, he met a girl in Tushan. The girl boiled water for them and helped them point out the water source. Dayu was very grateful to the girl, and the girl liked Yu very much, so they got married. Yu was so busy managing the water that they broke up after a few days together. When she left, the girl sent her to one journey after another. When he came to a mountain, Yu said to her, "that depends on when it will be delivered!" Water control will not look back. " The girl looked at Yu with tears in her eyes and said, "Go ahead, I'll stand here and come back for me when you calm down the flood." When Dayu left, he untied the vines around his waist and gave them to the girl. The girl touched the vine belt and said, "Go ahead, I'll stand here and wait until the vine blooms, the flood stops and people live and work in peace."
When Dayu left the girl, he led everyone around Kyushu and dug rivers. A few years later, the river was dredged, floods returned to the sea, crops were unearthed, willows sprouted, and finally people settled. Dayu happily came back overnight to find his beloved girl. Far away, he saw the girl holding the bunch of vines and standing on the high mountain waiting for him, but when he saw it, it turned out that the girl had already turned into a stone statue.
It turns out that since Dayu left, the girl has stood on this mountain every day and looked around. Rain or shine, freezing cold, never disappear. Later, the awl of grass penetrated her feet, and the seeds of grass sprouted and took root on her. She still held up the vine and looked around. Over time, the girl turned into a stone statue, with vines in her hands and vines in her blood. I don't know how long it took, but the vines turned green and tender, and new branches were sent out. I went forward to call his beloved girl, and tears fell from her eyes. At the moment, Jing Teng actually opened a golden flower.
Vitex negundo blooms and floods disappear. In order to commemorate the girl's heart, Dayu named the vine flower "Winter jasmine".
Propagation cultivation
Cutting is the main method, and layering and ramet propagation can also be used. Cutting can be done in spring, summer and autumn. Semi-lignified branches, with the length of 12- 15 cm, were inserted into sandy soil, kept moist, and took root about 15. Layering: Bury the longer branches in the sand without being scratched, take root after 40-50 days, and transplant them separately from the mother plant in the next spring. The division of plants can be carried out when they sprout in spring. When transplanting in spring, some overground branches should be cut off and lodging soil should be brought. During the growth process, pay attention to the fact that the soil can't accumulate water and be excessively dry, and properly fertilize 2-3 times before and after flowering. Prune and reshape in autumn and winter to keep more new flowers. Pests and diseases often occur leaf spot disease and dead branch disease, and 1500 times of 50% bactericidal wettable powder can be sprayed. Insect pests do great harm to aphids and giant salamander, spraying 50% phoxim EC 1000 times.
Jasminum nudiflorum likes warm and cold, and it can safely overwinter outdoors in Beijing and its south area, whether planted in ground or potted. Only potted plants can be planted in the north of Beijing, and they will be moved to a low greenhouse (5 ~ 10℃) to overwinter at -5℃. The flowering period of the Spring Festival is affected by the temperature, and1opens from south to north from late October to April. If you want to blossom in the Spring Festival, you can move the flower buds into the sunny room at 12 ~ 16℃ 2 ~ 3 weeks before the Spring Festival, and water them for 3 days 1 time, and often spray water on the branches and leaves.
