There are a lot of weeds growing in the yard, and they are still growing with herbicides, what shoul

Weeds are very vital, and if not rooted, new grass will grow within a few days. Weeds not only absorb nutrients from the soil, but also affect the growth of seedlings, as well as water infiltration and soil porosity. When weeding, some farmers will encounter weeds, no matter how they spray the medicine, they will not die, and they can't be eliminated, so what should they do to kill the weeds?

When weeding, don't hit big, hit small. When weeds first emerge, don't rush to take medicine, wait until a while before taking medicine. The area of grass contact with the liquid medicine is relatively small, and even if the drug is injected, it is not easy to die, and it is easy to **.

However, the weeds should not be too large, and if the resistance is too great, it is best to use the medicine in 2-4 leaves.

Fight inseparable. If there are some weeds growing in the ground, don't rush to take medicine first, and wait until the grass grows densely before fighting. When it is too thin, it is easy to cause waste of land and has no effect on ungrown grass, so when the grass is dense, it can achieve the effect of "annihilation in one fell swoop".

Neither wet nor dry. It is not dry when it is wet, and it is sprayed according to the moisture of the nursery. When the weather is dry, try not to take medicine.

Due to the dry weather, the weeds may lack water, and at this time the pores can be closed, and the injected drugs will not be absorbed a lot, the effect is not good, and the weeds are not easy to die. At this time, the weed already has 2 or 4 leaves, and if it is dense, two measures can be taken. Irrigate and water the seedlings, and secondly, drink more water when taking medicine, but do not reduce the overall concentration of the solution.

Otherwise, it won't work well.

It may also be a bad choice. If you choose the right herbicide that will effectively remove weeds, which herbicide is more suitable? To prevent broadleaf weeds, do not use white grass tracks, banda pine, krill.

2A 4 goats and so on are used in nursery forests and horseshoe meadows.

In order to control gramineous weeds, post-seedling herbicides for the prevention and control of gramineous weeds can be used, such as efficient grass energy, stable killing, real grass, catching, receptacle, and spraying. This agent cannot be used on grasses and meadows. This herbicide can also cause damage to the lawn while controlling grass weeds.

In order to choose a long-lasting herbicide, it is necessary to use green snow, methyl snow, benzyl, pila, soybean, amine, phenyl ether, and already trapped ketone herbicides (such as general killing, etc.); Heterocyclic herbicides, such as quick killing, light extinguishing order, etc. This herbicide lasts too long in the soil, but flower saplings planted after three years in nurseries using this herbicide can be harmed, so be careful.

Weeds are very vigorous, if not rooted, new grass will grow within a few days, and we can use herbicides that last longer. However, the effect of this herbicide remains for a long time. may cause an impact on other plants in the garden.

First of all, you can uproot them, so that they have no chance to grow again, but also use a hoe to hoe the ground loose, turn out the seeds remaining in the ground and throw them away, you can also choose the right herbicide, choose the right time to spray.

It is more convenient to use a weeder and is suitable for large areas of weeds, but the weeds between plants are not easy to clean; Splashing the weeds with salted water from pickled vegetables or duck eggs 3-4 times will inhibit weed growth.

As the saying goes, we must remove the roots of weeding, we can't just remove the surface, the main thing is to remove the root of the grass, otherwise the wildfire will not burn out, and the spring breeze will blow and grow, so we must find the right way.

Hello, the following is the answer to your query, I hope it will help you, the yard can be cleared with herbicides, but you need to choose different herbicides according to different situations. Generally speaking, herbicides are divided into organic herbicides and chemical herbicides, organic herbicides are more friendly to the environment, but the weeding effect is slow, and chemical herbicides have a better weeding effect, but there is a certain harm to the environment. Therefore, when choosing herbicides, we should comprehensively consider factors such as yard area, lawn species, weeding period, and **, and choose carefully.

The above is all my reply, I hope I can help you, I wish you a happy life

1.Methods include chemical weeding, manual weeding, mechanical weeding, physical weeding, etc.

2.Chemical weeding is the use of herbicides to control weeds.

3.Manual weeding includes manual weeding and the use of simple farm tools to weed.

4.Mechanical weeding is a weeding machine that uses animal power or mechanical power traction.

5.Physical weeding is the use of water, light, heat and other physical factors for weeding, such as covering the soil surface with dark plastic film to shade and increase the temperature of weeding.

Before weeds grow, the land can be covered with mulch, and the lack of light will inhibit the growth of weeds. If there are many weeds in the yard, you can use glyphosate and other agents to spray weeds to remove weeds. If the weeds in the yard are drought-tolerant and water-tolerant plants, you can give the weeds a lot of water, which can cause their roots to rot and gradually die in the later stage.

During the Spring Festival, weeds will grow in the yard, which can be more troublesome to deal with. In the spring, herbicides can be sprayed on the ground before weeds grow, which can inhibit the growth of weeds. Common herbicides include glyphosate, diluted with water, sprayed on the leaves of weeds, generally sprayed 3 or 4 times in a row, can get rid of weeds.

Weeds are very vigorous, but the number of weeds in the yard is not very large, so we can use the primitive method of pulling weeds to remove weeds, and we need to uproot weeds. Weeds can grow in a warm and sunny environment, and it is necessary to spread a layer of mulch on the ground to block the light, and insufficient light can prevent the rapid growth of weeds.

Some weeds can be used as feed for animals and can be eaten by animals such as rabbits or poultry. Destroying the growth environment of weeds can cause weeds to die, such as drought-tolerant weeds, plants are afraid of waterlogging, and can give weeds a lot of water, so that their roots are damaged and cannot continue to grow in the later stage. Weeding with fire, in a high temperature environment, weeds can no longer grow.

Weeds generally germinate in spring, have tenacious vitality, rapid growth rate, and strong reproductive ability. Plants generally grow on the roadside, in the field, in the forest and in the yard, and are distributed in various places. Weeds grow in the field and compete for nutrients and water for crops, which is not conducive to the growth of crops.

People usually use weeding tools or chemicals to control weeds.

Get rid of yard weeds:

If the garden has been abandoned for a long time, it is necessary to clean up the weeds, roots, seeds, and gravel in the soil before replanting. Weeds should be uprooted, because the roots that remain in the soil will germinate again with perennial weeds. You can turn the soil first and pour plenty of water to make the soil soft, so that the weeds are less laborious to uproot.

If the quantity is too large or cannot be cleaned, herbicides can be used; However, if a natural and non-toxic method is used, it can be removed by fire.

If the area is large, herbicides can be used to control weeds, but because different herbicides are suitable for crops and control objects, it is necessary to figure out what weeds and main plants grow in the courtyard before purchasing. According to the growth of weeds and plants, go to the agricultural material company to buy suitable herbicides, and prepare the concentration according to the instructions for weeding.

Second, there is one question that we still need to understand is:Due to the soil conditions and the climate environment suitable for long grass, we can plant grass on dirt roads. Of course, the climatic environment could not be changed artificially at that time, but it was possible to change the climatic environment by changing the soil. Where conditions permit, possible pastures should be eradicated.

If the raw soil is made into mature soil by some method, it is not possible to have the conditions for growing grass.

This is because there are people living in them, so there are no weeds.

The yard of the farmhouse is basically a hardened floor. Occasionally, some grass grows in the corners and will be pulled out at any time. Over time, no ripe grass seeds appeared.

There will be no grass growth. On the other hand, if no one cleans the place where you don't live for a long time, grass will grow over time.

Because there are always people in that yard doing activities. Grass will not grow.

Lu Xun didn't have a saying that there is no road in the world, and the more people walk, the more people who walk, the more roads they have.

I think it's because weeding is often done in rural yards, so we don't use herbicides.
