It seems a bit inappropriate to compare a weed that everyone hates with a great man that everyone admires. Some people may think it's blasphemy. However, I don't mean to disrespect Dr. Bai here. On the contrary, I admire his selfless spirit of "being selfless and benefiting others". From the perspective of my Buddha: all beings are equal. Man is life, so is grass. There is no distinction between nobility and inferiority in essence. What can distinguish the high and low is their behavior, or spirit.
When people invite peanuts, they are regarded as distinguished guests. At that time, during the Great Leap Forward, the whole country was surging and thriving, and people's enthusiasm for socialism was unprecedented. The agricultural policy at that time was "grain as the key link". If you want to get more food, you have to accumulate more fat, accumulate more fat and raise more pigs. Whether pigs can be raised well depends on whether there is enough feed. The emergence of Alternanthera philoxeroides came into being at the right time. People took a fancy to its characteristics of vigorous vitality, large grass yield and forage grass, and introduced it widely, hoping to help more food production. However, people always ignore one thing. Alternanthera philoxeroides has all the advantages people want, but it also has a fatal disadvantage, that is, its vitality is too strong. Perhaps some readers are a little strange to see here: strong vitality should be a good thing, just feed it. How can it be considered a shortcoming? This is the problem. Generally, a strong vitality will be an advantage, but if it is strong enough to occupy other people's territory, destroy other species, affect the ecological balance and affect the normal life of mankind, it is definitely not a good thing. This is the case with Alternanthera philoxeroides, which has been widely introduced and spread rapidly by virtue of its superior reproductive ability, covering the water surface, blocking waterways, engulfing farmland and strangling crops. Wherever it can reach, it is its own, and it is quite arrogant and unified.
This situation is quite similar to water hyacinth, and the ending is naturally no different. Together with Eupatorium adenophorum, Spartina odoratum and other *** 16 species, it was included in the list of the first batch of exotic species that invaded China by the State Environmental Protection Administration on March 6, 2003. The state called on the people of China to kill anyone who saw this 16 species and put an end to all evils.
However, it is easier said than done. Water peanuts are determined to take root and settle down in this land. Whether you eradicate it manually, poison it with drugs, or surround it with natural enemies, you will always stubbornly resist and refuse to give up the occupied position. So until today, people are still struggling with these foreign invaders. It is foreseeable that this tug-of-war will last at least a long time in the future. Think about it, too. A single spark can start a prairie fire. How easy is it to put it out? This is an old saying of China: "It is easier to ask God than to send him away". If I know today, why should I know? If we can conduct in-depth investigation and study before the introduction and find out the details, we will not lead the wolf into the room. Why is such a big blow having little effect now? However, everything in the world is sold, but there is no regret medicine. Water under the bridge, you can't go back in time.
It is wishful thinking to say that biological invasion is just a step that people have found for themselves. At first, peanuts and water hyacinth stayed well in their hometown of South America. Although life is hard and they are not rich, it is not surprising that they can always lead a so-so life. They don't necessarily have the idea of leaving their hometown to seek development abroad. Therefore, it may not be their intention for Wan Li to come to China not far away. If they can speak, they need to ask their opinions. Whether they will come is uncertain. Therefore, they will say: it's not that I want to covet your good things, but that I have long been greedy, and I ... >>

English name: Alligator Weed
Chinese synonyms: Alternanthera philoxeroides, Alternanthera philoxeroides
Taxonomic status: Amaranthaceae
Identification characteristics: aquatic plants have no root hair, and the stem length is1.5-2.5m; Terrestrial plants can form fleshy storage roots with a diameter of about 1cm, hairy roots, a plant height of 30 fa m, solid stems, the longest internodes 15cm, a diameter of 3-5mm and a small pith cavity. Leaves opposite, oblong to obovate-lanceolate. Head peduncle 1.5-3 cm.
Biological characteristics: perennial herbs, asexual propagation with stem nodes; Dry land type fleshy storage roots can produce adventitious buds when they touch * * *. They can grow 2-4 cm a day during the peak growth period. Flowering in May-10, they often do not bear fruit. Origin: South America; It is widely distributed in temperate and subtropical regions of the world. Distribution of China: Almost all over the south of the Yellow River Basin in China. In recent years, naturalized plants have also been discovered in Tianjin.
Causes and hazards of introduction and diffusion: 1892 appeared on an island near Shanghai. It was planted as pig feed in 1950s, and then escaped, causing a grass disaster. The specific manifestations are as follows:
(1) blocking the waterway and affecting water traffic;
(2) crowding out other plants to make the community species single;
(3) Covering the water surface, affecting the growth and fishing of fish;
(4) endangering farmland crops and causing yield loss;
(5) A large number of ditches proliferate in the field, which affects the irrigation and drainage of farmland;
(6) encroaching on wetlands and lawns and destroying the landscape;
(7) Mosquitoes and flies breed, which is harmful to human health.
Control method:
(1) Agasicles hygrophila, an exclusive natural enemy insect in South America, has a good control effect on aquatic plants, but its control effect on terrestrial plants is not obvious.
(2) Mechanical and artificial control is suitable for low density or newly invaded populations.
(3) Herbicides such as glyphosate, roundup, Alternanthera philoxeroides, etc. Used for chemical control, it is effective on the aboveground parts in a short time.
Question 9: What are the disadvantages of water peanuts? You mean a plant, right? This plant has a strong vitality and can grow well under harsh conditions. If you encounter good climate and water and soil conditions, you will expand the area and absorb nutrients. What are the consequences of this? Other plants are at a disadvantage in the competition and are eliminated by natural selection. Finally, a large area of Alternanthera philoxeroides was left ... Diversity and balance were destroyed.
Question 10: characteristics of Alternanthera philoxeroides: characteristics, harm performance and control methods of Alternanthera philoxeroides.
Characteristics of Alternanthera philoxeroides: aquatic plants have no root hairs, and their stems are as long as1.5-2.5m; Terrestrial plants can form fleshy storage roots, with a diameter of about 1cm, hairy roots, a plant height of 30cm, a solid stem, the longest internode 15cm, a pith cavity of 3-5mm, opposite leaves, oblong to obovate-lanceolate, a total stalk 1.5-3cm, and white or pink flowers.
Biological characteristics: perennial herbs, asexual propagation with stem nodes; Dry land type fleshy storage roots can produce adventitious buds when they touch * * *. They can grow 2-4 cm a day during the peak growth period. Flowering in May-10, they often do not bear fruit.

(3) Herbicides such as glyphosate, roundup and Alternanthera philoxeroides are used as chemical control, which are effective for aboveground parts in a short time. Monopterus albus can live in the underwater stem where water peanuts creep and spread in the water, and water peanuts are the first choice for raising eels.
Alternanthera philoxeroides has strong adaptability, and its cold resistance exceeds that of water hyacinth, water hyacinth and other aquatic plants. It can overwinter naturally, germinate and grow when the temperature rises to 65438 00℃, and the optimum temperature is 22~32℃. When the temperature is lower than 5℃, the above-water part withers, but the underwater stem can still stay underwater without shrinking. When raising eels, the clustered water peanuts are put into the pond, and the fibrous roots on the underwater stems can absorb the nutrients in the water and grow. Generally, the area for stocking water peanuts can be 30%~50% of the pond area. In the management of water peanuts in eel ponds, when it is found that the vitality of water peanuts is declining and shrinking, water peanuts in ponds can be fished out and replaced with water peanuts grown in ditches with strong vitality. When changing, the eel will hide in the water peanuts in the pool, so it is necessary to fish the water peanuts to the edge of the pool, turn over and let the eel climb into the pool by itself.
