Shyness of flower language
Gently touching the leaves of this plant will immediately close and droop, even if a gust of wind blows, just like a shy girl. So its flower language is-shyness. People born with this flower blessing are very shy and timid. I feel particularly keen and have strong self-esteem. However, it will be much easier if you are with people who know yourself. Making friends is more important than quality. You like the feeling of running water.

The origin of the name mimosa
Unlike animals, plants have no nervous system and muscles, and will not feel external stimuli. Different from ordinary plants, mimosa will lower its petiole and close its small leaves when exposed to the outside world. This action is understood as "shyness", so it is called mimosa.
The legend of mimosa
Once upon a time, there was a very handsome young man who often went out fishing. One day, he saw an old man sitting by the river and said to himself, "Fishing! Fishing! Fishing! Small fish never come, big fish come. " Said the big fish really swam to the old man. The young man said to the old man, "shall I learn fishing from you?" The old man said, "There is nothing to learn about fishing. It seems that you are honest. Let me tell you a secret. As long as you keep walking along this river bank, something good will happen. " When the old man finished, he disappeared.
The young man was very happy and thought, I must have met a fairy, so I walked along the coast. It's getting dark, so let's move on. There is a big bay full of lotus flowers in front of us. At the water's edge, the door of a family was open and the lights were on. A young girl is sitting knitting silk. Before leaving, the young man asked, "Excuse me, what is this place? I have lost my way. " The Weaver Girl said, "This is the Lotus Village, and I am the Lotus Girl. If you are tired from walking, you can come in and have a rest. " The young man sat for a while and was about to leave, but the lotus girl never gave up and sent him out of the door. When the young man came home, he was crazy and thought that the lotus girl must be a fairy. The old fisherman said that something good will happen if you go forward. Maybe the fairy came down to earth and wanted to marry her. The next morning, the young man walked along the river bank again, and when it was dark, he arrived at Lianhua Village. The Lotus girl was still there, and her attitude was much more intimate than yesterday. She told the young man to take off his tattered jacket and mend it for him. The young man said, "I am alone!" " "Lotus girl didn't hear. Mend the clothes and send the young man out. It was already midnight when the young man got home. He couldn't sit still and stood still. He just turned and ran to the river, and then went to Lianhua Bay. He saw a big lotus in the bay, so he called the lotus girl. Sure enough, the lotus girl came in waves. She said, "My father forbade me to associate with mortals. From now on, we will never meet again. The young man cried, crying very sadly. Miss Lian comforted: "As long as you are sincere, I will elope with you." The young man swore to heaven that he would never change his mind. Miss Lian took the young man to the depths of the jungle on the horizon, and a small bridge went straight to the door of the hut. They crossed the bridge and entered the house. Everything in the house is fully equipped, and there is a loom. They got married there. The young man goes out hunting every day, and he can hunt some mountain rabbits and pheasants without much effort. In his spare time, he goes sightseeing in the mountains. Miss Lian is very hard. Every day, besides weaving, she has to go to the mountains to plant mulberry.
Year after year, Miss Lian's hair is not so bright, and her rosy face is not so cute. The young man said to him, "You are too tired, you are old, take a rest!" " "Lotus Girl shook her head and said," Look, how beautiful it would be if many barren hills turned into mulberry forests! "Lotus Girl pulled out a needle from her head and handed it to the young man, saying," This needle is a treasure that can subdue wild animals. You should use this precious needle to turn this uninhabited mountain area occupied by killed animals into a paradise for the people. Note that this precious needle must not fall into the hands of others. "One day, the young man went hunting in a distant wild mountain and found a dark hole. He felt very strange. When he entered the hole, a tiger came at him. He pointed to the precious needle that Lotus Girl gave him, and the tiger ran away. There is a gate in front. When you pushed open the door, the light came on. A young girl is sitting on the kang. She is much more beautiful than Lotus Girl. The girl welcomed him and sat on the kang with food and drink. They became close. Three days later, the girl said that she wanted to go out to visit relatives, but she was afraid of being hurt by tigers and wolves. The young man said, "I have a precious needle." "You can defeat all the wild animals." Then he handed the precious needle to the girl. Who knows that as soon as the girl walked out of the hole, the hole was tightly closed and the young man was forbidden to enter the hole. He remembered what Lotus Girl said, and it was too late to regret it. When Miss Lian saw that the young man didn't come back, she pinched her fingers and counted. She knew in her heart that the young man had become an ungrateful person and could not help crying. On second thought, save his life! She also has a treasure, which is the key to this mountain. Miss Lian arrived at the entrance of the cave and pointed the key at the mountain. The cave door was wide open, and the young man was ashamed and uneasy. Miss Lian said in tears, "I never dreamed that you were such an ungrateful person!" " They were walking back when the girl caught up with them and shouted, "Young man, come back!" " "Lotus girl said to the young man," you can't look back at her. As long as you look back, you will die. " The girl still shouted at the back: "Young man, think about it, where are you going to find a lovely beauty like me?" The young man was tempted and looked back. The girl took advantage of the moment when his mind was shaken, waving a handkerchief and turning the young man into a weak grass growing on the ground.
Miss Lian stared at the grass, and all the leaves of the grass agreed, like crossing their hands and confessing, and immediately hung down her petiole shyly to show her mistake. Miss Lian said, "Young man, you can still be ashamed to admit your mistake." Later, people called it "mimosa" and it became a favorite grass.
The reason why mimosa is "shy"
The research team led by Takashi Tsuya, a Japanese professor at sophia university, uncovered the mystery of the closed movement of mimosa: the cells of mimosa are supported by tiny reticular protein "actin". When the closed movement occurs, the phosphoric acid of actin will fall off. As long as the mimosa is allowed to absorb the compound that does not let the phosphoric acid fall off, it will not change after contact. Professor Tsuya pointed out that when actin bundles are dispersed, cells are destroyed, resulting in water depletion and closed movement. Femoral actin generally exists in animal muscle fibers and is related to muscle contraction. I didn't expect it to be found in mimosa. It's quite rare.

3. Predict earthquakes. According to Turkish seismologist Erjiang, a few hours before a strong earthquake, the leaves of mimosa, which are sensitive to external touch, will suddenly shrink and then wither. In earthquake-prone Japan, scientists found that mimosa blooms during the day and closes at night under normal circumstances. If the leaves of mimosa are closed during the day and open at night, it is a precursor to an earthquake. For example:1938 65438+1October1At 7: 00 in the morning, the mimosa began to bloom, but by 10, all the leaves suddenly closed. Sure enough, 13 had a strong effect. During the period of 1976, members of Japan Earthquake Club observed the abnormal closure of mimosa leaves many times, and then an earthquake occurred.
Mimosa planting
The planting technology of mimosa is simple and the management is extensive. The requirements for climate, sunshine and soil are not strict, but the fertile and loose sandy loam is better, and the warm and humid environment is better.
1, planting method. Generally sow and propagate, and sow from late March to early April. Spread the seeds evenly on the fine soil, covering about 65,438+0.5 cm. When the temperature is about 65,438+08℃, the seedlings can emerge in about 65,438+00 days (usually they will grow after being buried without special management). Seedling growth is slow, and it can be planted when it is 7-8 cm.
2. On-site management. Plant spacing is 25-30cm, loosen soil, weed and water in time. Potted indoors, watered every day in summer 1 time. Fertilize every month 1 time. If you don't want the plant shape to be too big, you should reduce the amount of fertilization or even don't need fertilization.
3, pest control: basically no pests and diseases. If there are slugs, they can be controlled with fresh lime powder in the morning.
