Why are the weeds in the field so tenacious?

Because weeds naturally have an advantage that other crops do not have, the crops we grow are left behind after artificial selection, although the yield is high, but the stress resistance may be poor. Weeds are eliminated by themselves, and the rest are drought-tolerant, barren, and spread in a variety of ways.

First of all, weeds have amazing fecundity. Weeds not only produce more seeds, but also have a long seed lifespan and can germinate in the soil for many years. The lifespan of seeds in general crops is only a few years, and it is very difficult to find a crop that grows on its own every other year.

Secondly, weeds have a tenacious vitality. Some weeds are drought-tolerant, cold-tolerant, and salinity-tolerant; Some weeds are resistant to waterlogging and barrenness.

Because every living being has a living consciousness. So they will keep growing, some small grasses will grow in the gaps, and their roots and stems will become very strong, so the vitality is also very strong. I was amazed at the tenacious vitality of the grass, it does not have the beauty of flowers, nor the tallness and uprightness of trees, but it has the spirit of obscurity and dedication, and has the tenacious vitality of "wildfires are inexhaustible, and the spring breeze blows and grows".

It is willing to decorate the world with its body, and the grass is nobler than the peony and nobler than the lotus. It grows in mountains, rivers and plains; It flourishes in ponds and marshes, river banks. Even in forgotten corners, potholes, and dark places, it can grow tenaciously and silently withstand the wind and rain.

It only relied on the thin loess to wrestle with fate, compete with stubborn stones, and after tenacious struggle, finally showed up in the bright world with hope.

The vitality of weeds is much more tenacious than that of these flowers, the main reason is that weeds have low requirements for the natural growth environment, and can survive in places with soil, water and sunlight, even if there is no water for a long time, they can survive tenaciously for several days.

Because weeds are very fecund, there are many species, and they are widely distributed on the earth. They generally produce a large number of seeds, and some can reproduce two or three generations a year, which is a surprising number. The roots and stems of some weeds are also the main reproductive organs, and often we remove the grass from the ground, and it doesn't take long for new grass to grow on the rhizomes underground.

Weeds also have tenacious vitality, drought tolerance, waterlogging resistance, cold tolerance, salinity tolerance, etc., so they can be found everywhere on the earth. Weeds not only have a large number of seeds and are particularly vigorous, but they also spread in a variety of ways, making it impossible to get rid of weeds. The seeds of some weeds germinate even after years in the soil or water.

The seeds of many weeds are small and light, and when blown by the wind, they float in all directions and make their homes everywhere to multiply.

Because weeds are very fecund, there are many species, and the roots and stems of some weeds are also the main reproductive organs. In addition, weeds also have tenacious vitality, drought resistance, waterlogging resistance, cold resistance, salt and alkali resistance, etc. Finally, weeds can spread in multiple ways, making it impossible to get rid of them.

March 25, 2020: In addition to their ability to grow in particularly harsh natural environments, weeds are so tenacious because they grow in particularly fertile soils, and these natural fertilizers are.

The wildfire blows inexhaustibly, and the spring breeze blows and grows. This sentence is a representative description of the tenacity of the vitality of wild grasses, because wild grasses grow on the mountains and grow on grass, so their vitality is very tenacious.

As long as there is soil, there are nutrients, it will breed some wild grasses. Because weeds are the ones that draw nutrients from the soil at the point of growth.

All things in nature are natural selection, and only the fittest can survive. Wild grasses are able to survive in the natural environment of jasmine because they understand this natural law.

Because this is the survival strategy of wild grasses, sowing more seeds to survive.

The vitality of the weeds itself is relatively tenacious, or how can there be a poem, the wildfire is not burned and the spring breeze blows and grows.

Because it is a weed, it has a tenacious vitality.

<> because weeds are very fecund, there are many species, and the roots and stems of some weeds are also the main reproductive organs. In addition, weeds also have tenacious life balance, drought resistance, waterlogging resistance, cold resistance, salt and alkali tolerance, etc. Finally, weeds can spread in multiple ways, making it impossible to get rid of them.

Weeds are mostly small-seeded herbaceous plants with seeds distributed on the surface of the soil, while crop seeds are mostly sown deeper than the seeds. Therefore, weeds are easier to grow first, and when weeds grow, they cover the light and space needed by crops, so crops are buried by weeds, and weeds grow faster than crops.

The growth of weeds is not conducive to the growth of food, and weeds in farmland compete with crops for fertilizer, light, water and space. Farmland weeds can also reduce the yield and quality of crops, such as the toxic effect of wheat mixed with wheat and the flour that is ground into it. Farmland weeds can also breed pests and diseases, and some weeds are infected by insects, and then insects can spread the virus from the weeds to crops.

A herbaceous plant endemic to the western region of the camel thorn, on the Gobi Desert, no matter how harsh the ecosystem and living environment are, it can tenaciously survive and expand its living range.

Curly cypress is also known as "Nine Dead Soul Grass", and its vitality is extremely strong. You don't water it for a month, and it's just curled up; When you water it again, it immediately relaxes as if nothing had happened.

The most tenacious plant.

In the plant world, lichens are the most tenacious. According to experiments, lichens can grow at a low temperature of -273 degrees Celsius, maintain vitality after 6 years in a vacuum, and survive at temperatures twice as high as boiling water. Therefore, it can grow in the desert, Antarctica, the Arctic, and even on the back of a large sea turtle.

Why do lichens have such tenacious vitality? After a long period of research, people finally found it"Mystery"。It turns out that lichen is not a simple plant, it is composed of two types of plants"Partnership"Composition, one is fungi and the other is algae.

The fungus has a great ability to absorb water and inorganic matter, algae have chlorophyll, which uses the water, inorganic matter and carbon dioxide in the air absorbed by the fungus as raw materials, and uses sunlight for photosynthesis to make nutrients, which can be enjoyed together with the fungus. This close cooperation is the secret of the tenacious vitality of lichens.

Camel grass, in the Gobi Desert, camel grass has the most tenacious vitality.

Cactus, in fact, there are very few plants that meet your requirements

The plant has no emotion, no thought, it develops from itself, to adapt, to resist, there is only one goal, it is towards the pursuit of strength is often better than character, the structure of the grass itself, the body, etc., help it grow in the predicament.
