Plant war without gunpowder

  In order to expand the territory, mankind has not stopped the war for thousands of years; the lions of the animal kingdom are fighting for territory at all costs. The same goes for plants. In order to expand their territory, they use various “tactics” to stage a battle without gunpowder. Let’s take a look at how these “plant kings” have made many tricks to “dominate the world.”
  ”Air-ground double-click” Solidago canadensis dominate
  there is a plant used to be famous, called Solidago canadensis, plant height of 1.5 meters to 3 meters, highly reproductive, spread fast, and the sun around the plant fight, fight fertilizers, turf war, It can be said that “after my flowers bloom, a hundred flowers kill”. This kind of flower can be seen in river beaches, wastelands, both sides of roads, empty homesteads and other places. The sea of ​​flowers rolls like a blazing flame, and the array is as dense as a battlefield. It poses a serious threat to biodiversity and is called an “ecological killer.” “, “Overlord Flower”.
  So, what is the secret weapon that allowed Canada to sweep the army and dominate the world?
  It turned out that the Canadian Goldenrod’s “land-air double-tap tactics” made it utterly unstoppable. Solidago canadensis is native to North America, also known as Solidago canadensis. It was first introduced to my country in the 1930s. It was originally planted in Shanghai. It was a perennial herbaceous plant of the Compositae family. It was originally only planted in the garden and has a strong competition for sunlight and nutrients. , The power of moisture. Unexpectedly, the “ambitious” Solidago canadensis is not reconciled to staying at the small door forever. It yearns for a broader sky of nature, so it uses wind, birds and other “air forces” to bring the seeds it produces to all directions. Soon, its people settled in other places. By the 1980s, my country’s Zhejiang, Jiangsu, Anhui, Jiangxi, Guizhou, Hunan, Hubei, Guangdong, Guangxi and other places were full of them. Moreover, they are still spreading to other suitable growth areas at a staggering rate. Not only do they have the “military power” of more than 20,000 seeds per plant, they also engage in root propagation, forming new plants on the roots, woven into a super powerful reproduction network, wherever they go, other crops and weeds do not fight against themselves. If you lose, all will die.
  Scientists have investigated that the roots of Solidago canadensis secrete some substances, which can inhibit the growth of sugar maple and other plant seedlings, and also inhibit the germination of herb plants including itself. In Denmark, studies have shown that acetylene gas still exists in its root system, and acetylene gas is also a killer that inhibits the growth of other species. It is with the power of a land-air two-headed force that Canada Goldenrod has become unscrupulous. According to an investigation conducted by relevant experts in Zhejiang, it was discovered that a small group of six Canadian yellow flowers had evolved into a large group of more than 1,400 plants 8 years later. Solidago canadensis has severely damaged the natural vegetation and ecosystem, posing a great threat to agricultural and forestry crops. At present, it has been listed as a key control target by the agriculture and forestry department.
  ”Revival” ragweed expansion Dafa
  addition Solidago canadensis by “air-ground tactics” to dominate, become a serious threat to biodiversity “plant killer”, the plant kingdom there is another “common enemies” of the plant killer – Ragweed, its way of dominating is also very interesting.
  Ambrosia ragweed, also known as ragweed ragweed and American wormwood, is a wild vicious weed from North America. It invaded my country in the 1930s and is one of the ten most vicious invasive weeds announced by the Ministry of Agriculture. It has a strong “exclusive” nature. , Where it grows, it is difficult for other plants to survive. Experiments show that if two or three ragweed plants are mixed in a square meter of corn field, the corn yield will be reduced by 30%. If more than ten plants are mixed, there will be no grain.
  In order to “dominate the country”, ragweed produces a peculiar seed, which can bear the burden of humiliation, “salary and taste the courage”, only when the time is right, it will regenerate from its cocoon and endanger the rivers and lakes.
  We know that seeds have a lifespan, and ordinary seeds lose their vitality after a certain number of years. The lifespan of willow seeds is extremely short, and they can germinate only within 12 hours after maturity. The lifespan of poplar seeds is generally not more than a few weeks. The lifespan of most crop seeds is only 1-3 years under normal storage conditions. But the seed of ragweed is different. It has a tenacious vitality, and it will not “snap eyes” for 30-40 years.
  Each plant of ragweed bears at least tens of thousands of seeds, which can be spread in the wind, with the soles of the birds, with the soles of people, or in water, vehicles, etc. They all have hooks and can be attached to people’s clothes or packaging sacks, and travel at will. Among the spreading seeds, about 70% of the seeds germinated and grew under the conditions of suitable moisture, soil, and temperature, and 30% of the seeds were temporarily sleeping. They were indignant about the “eccentricity” of moisture, soil, and temperature. Sleeping without dying, even 30 or 40 years, will make a comeback. With these stubborn seeds, can ragweed still not dominate the world?
  Dandelion by “Dongfeng” seats and seize territory
  to the family and will not be other alien plants “punish clan”, they will try every means plants accounted for the hills, seats and seize territory, until gain a place in nature.
  The little dandelion is a model of territorial expansion. When the dandelion seeds are mature, they must leave the plant and take root and germinate elsewhere. However, they are single and weak, have no feet or legs, and have no artificial planting. How can they seize the ground and take root? Don’t worry, Dandelion is already familiar with Zhuge Liang’s tactics of “borrowing the east wind” to burn Cao Ying. Through the wind, his children and grandchildren can multiply everywhere.
  Dandelion knows that it is only a weak plant among herbaceous plants, so it produces the fruit as “achene”, which is small and light, easy to spread, and then grows some parachute-like crests from the top, which is more convenient for sailing. In this way, after the seeds mature, they fly far away when the wind blows. When these fruits fall to the ground and meet suitable conditions for germination, they will immediately sprout and grow into new dandelions.
  Similarly, plants that “borrow the east wind” include willow, cotton, and zelkova. Their seeds are hairy and can fly far away in the wind.
  However, the seeds of plants such as elm and maple trees are hairless and cannot be scattered with the wind, but in order to seize the country, they are very “cunning”. They grow small horns like “wings” on the fruit, and use the wind to “glide. ” So they can also slide far to breed.
  There are some plants in the grassland and desert, such as Salsola, Gypsophila, etc. Their plants have countless branching branches, forming a spherical shape. When the seeds mature, the base of the plant will naturally break off, and the whole plant can roll with the wind like a ball, and the small seeds can be scattered on the ground.
  Bidens immigrants move “animal soldiers”
  plants with high IQ survival wisdom. Plants such as dandelions use the wind to spread tiny seeds to compete for territories, so how do plants whose seeds cannot be blown away by a strong wind “migrate”? Don’t worry, they have their own brilliant tricks. If you can’t rely on the east wind, then move their troops! What soldiers to move? Of course it is an active soldier, an animal soldier!
  In late autumn, if you travel in the woods in the wild, you will find that many weeds or seeds are stuck on your clothes and socks. These little things are difficult to remove even if you beat them with your hands or brush them. Who are they? Why do they stick to us so affectionately? It turns out that they are the fruits of high “IQ” plants such as cocklebur, bidens, pigs, and tribulus. Plants such as cocklebur and bidens grow these fruits with some hooks and thorns. As long as you get close to them, they will hook firmly to you or the animal. When you carry them around unintentionally, they have already taken root in those places without knowing it!
  What about seeds without hooks or thorns? Smart plants have their own solutions. Wild fruits in the forest, such as mountain sandalwood, grapes, cherries, pears, apples and other fleshy plants, have a coup. They grow brilliant and delicious fruits that attract people and animals to come and taste. After the seeds of these plants are swallowed by animals, they are difficult to digest in the animal’s gastrointestinal tract. They will be excreted with animal feces and can germinate as long as they are not broken. In this way, after wild fruits are swallowed by animals and then excreted with feces, these seeds have found a new destination.
  The fruits of some wild plants and cultivated plants mature at the same time, and their survival methods are even more scheming. They are “mixed with fish and pearls” and spread through human sowing and harvesting. For example, the fruit of barnyardgrass matures at the same time as rice, and it spreads with the planting and harvest of rice. It is a famous weed in rice cultivation.
