What kind of weeding is used in the orchard to control weeds safely, efficiently, and effectively wi

The method of orchard weeding, if you pay attention to high efficiency and safety, weeding is still the main weeding method in the current orchard management, through weeding not only reduces weeds, but also loosens the soil, but the disadvantage is that it is time-consuming and laborious, and long-term tillage is not conducive to the ecology of the soil. When it comes to weeding in orchards, I have the following opinions.

1. Weeds should be removed in seasons

For orchard weeding, in general, the main thing is to do a good job of weeding in spring, after entering the summer, there is no need to carry out excessive weeding, when the weeds cover the ground, which can not only reduce the temperature in the orchard, but also play a role in maintaining soil ecology. In autumn, another weeding operation can be carried out to reduce the consumption of nutrients by weeds in the soil, and at the same time, the weeds can be made into organic fertilizer and returned to the soil.

2. Manual weeding is safe and efficient

If in the case of abundant labor, the method of adopting manual weeding is also the safest and most efficient, but it is more labor-intensive and laborious, if the orchard area is relatively small, the method of manually removing weeds can be taken, and the weeds that can be removed can be covered with grass in some places of the orchard, not only safe and efficient, but also will not pose a hazard to the soil and the root system of fruit trees.

3. Use machinery to remove weeds

At present, there are some relatively light weeding equipment, such as weeding machines, which can be operated by one person, and the speed of weeding is much faster than that of simple manual work, and basically will not cause damage to fruit trees and soil, which can also be called a way of safe and efficient weeding.

4. Weeding with grass

The way of weeding with grass is to plant a kind of grass in the orchard, this grass can inhibit the growth of other weeds, wait until this grass grows to a certain height, after using machinery to knock down at one time, do not need to clean up, this grass covers the ground in the orchard, can not only play the role of suppressing the growth of other weeds, but also can reduce the evaporation of soil moisture, maintain soil moisture, is conducive to the growth of fruit trees, this method is also a very good weeding measure.

5. Other weeding methods

Usually the method of weeding in the orchard is spraying herbicides, which is simple and efficient, but it is prone to pesticide damage and long-term use will cause damage to the soil ecology. In addition, there is also the method of three-dimensional farming in the orchard, which means that by raising poultry in the orchard, it can also play a role in removing weeds, but the quality and quality of the fruit will be affected by the increase of flies.

To sum up, what kind of weeding method is safe and efficient, and the above corresponding weeding methods can also be combined with the actual situation of the orchard itself.

At this time, you can choose the way of manual weeding, you can choose herbicides, you must choose the right pesticides according to the variety of crops, you must choose pre-budding herbicides, you should usually water and fertilize frequently, and then you should improve the yield of crops.

I think it's best to use a slightly toxic herbicide, which will completely remove the weeds without harming other plants and soil.

I think it's better to use a herbicide with a cover grass. And it is also possible to use a weeder. Most people now use weeders.

I think I can keep a flock of ducks in stock, so that we can weed efficiently and without harming the soil.

Weeding in the orchard orchard is good. For fruit growers, the orchard is overgrown with weeds and grows quickly. How to manage weeds in an orchard is a very headache topic.

Some people say that the weeds in the orchard need to be completely removed, otherwise the weeds will compete with the fruit trees for nutrients and growth space, resulting in poor fruit trees, low yield, and poor quality.

<>So, should the cause of the orchard be cleared out? What are some commonly used and effective methods of weeding, and what are the advantages and disadvantages of each? The practice of planting grass in the orchard is good, what are the methods when planting grass in the orchard, and what management links should be paid attention to?

Any herbicide has a very great lethality to the root system, especially shallow root crops, such as peaches and pears, the root system is easily damaged, which seriously affects the fertilizer and water absorption rate, so it affects the growth, and has a greater impact on the yield and quality, especially on the young peaches, pears, plums, pomegranates, and the growth is stunted, or dies.

It should be noted that when the grass grows to a certain height, the grass must be pruned back into the field in time to avoid affecting the growth of fruit trees, whether through artificial planting or natural grass. Normally, when the good grass in the orchard is to be planted to a height of 30-40 cm, the grass needs to be mowed, the height of the mowing stubble is about 5-8 cm, according to the mowing twice a year, it is recommended to cover the weeds evenly on the tree tray when mowing, or collect compost for use in the orchard.

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me a lot, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you. That's all for sharing, if you like me, please follow me. If you guys have any ideas, you can let us know in the comments below.

I think it's better to weed. Weeding can be done by using some herbicides, which will not harm the fruit trees and can be better supplemented with fertilizer.

It is good to grow grass, which can avoid the appearance of sunburn, can help the growth of fruit trees to become shallower, and can also enhance the endurance of the soil.

In the orchard, I think it's better to weed, we can buy a weeding machine to remove the corresponding grass, so that we can also increase the yield of the fruit trees.

It should be better to control weeds, which is beneficial to fruit trees and can increase yields.

Plant grass to avoid sunburn, help fruit trees grow shallow, and increase soil tolerance.

Chemical weeding is also what we often say about herbicides, because this method saves time and effort, and is economical and efficient, so it has been used since the introduction of China in the 50s of the last century.

Advantages: At present, the most widely used herbicide is glyphosate, the period of application of glyphosate is good in the middle of weed growth, when the weeds have a certain height, the liquid medicine is easy to be absorbed, the weeds are sensitive to drugs, and the grass seeds have basically come out, and the weeds decay and decompose in the rainy season after they die, which is conducive to killing more weeds at a time.

Disadvantages: Although glyphosate is easy to use, it will easily cause pesticide damage to fruit trees if used improperly, especially there are several points to pay special attention to.

When using glyphosate, the nozzle must be facing downward, and the spraying should be even, so that the leaf surface of the weeds does not drip out;

Do not reduce or increase the dosage at will, because the dosage is too high, the aerial part of the weed will die quickly, lose the absorption and conduction function, affect the elimination of the weed root system, the dosage is too low, and the effect is not good;

If it rains within 8 hours of spraying, it needs to be sprayed again;

Glyphosate is acidic, and the sprayer must be washed with water after spraying;

Do not mow the grass before and after spraying, otherwise it will affect the effect, such as spraying after mowing, wait until it grows to more than 40 centimeters before spraying;

Do not spray in the morning when the wind exceeds level 3, the dew is heavy, and on rainy days;

Glyphosate will decompose when exposed to soil, so don't spray glyphosate directly on the ground.

In the orchards of the north, there are generally 29 families and more than 80 species of common weeds, including Matang, ox tendon grass, dogtail grass, teff, wild oats, white hair, spiny cabbage, bitter wheat cabbage, mugwort, dandelion, mustard greens, purslane, nightshade, iron amaranth, triangular grass, plantain and so on.

In general, orchard weeds are mainly annual and biennial weeds, and perennial root-based weeds also occur to a certain extent. Annual and biennial weeds are divided into spring grass and summer grass. Spring grass begins to grow in early spring, peaks in May, and withers after June.

Summer grass begins to grow in mid-to-late May, peaks in July and August, and dies in late autumn.

So what herbicides can orchards use? Paraquat gum

Paraquat is currently banned and the only one that can be legally used is paraquat gum, which will expire on 25 September 2018. The cost of paraquat gum is 10-12 yuan per mu, it needs to be diluted twice, it is not very convenient to use, it is not suitable for large growers, paraquat gum is fast, has a wide grass killing spectrum, has an effect on small flying peng, does not hurt the root system, and is suitable for orchards.

Glufosinate-ammonium

The cost of use is very high, generally 10-15 yuan per mu, weeding is effective in about 3 days, 7 days of dead grass, the time to control weeds is not as good as glyphosate, and it is effective for small flying peng, cow tendon grass, etc., glufosinate-ammonium does not hurt the root system, and is suitable for orchard use.

Diquat fast

Generally, the cost per mu is 8-10 yuan. The weeding mechanism is similar to paraquat, but the herbicide spectrum and weeding effect are not as good as paraquat, the dead grass is fast, the green is faster, and the green begins to return in 10 days, the cost of this herbicide is relatively high, and the ideal weeding effect will be achieved when the amount per mu is large.

It is best not to use glyphosate in the orchard, because glyphosate is more toxic and may cause the fruit tree to die.

The orchard is a glyphosate, which is not very concentrated, and can be done with a little paraquat or something.

Orchards can not use glyphosate, glyphosate will reduce the iron and zinc in the soil, and spraying glyphosate will be directly absorbed by fruit trees, resulting in rot in the roots of fruit trees, leaf yellow, etc., orchards can use glufosinate-ammonium, glufosinate-ammonium has no effect on the root system of plants, and can remove weeds.

Orchards are an important part of agricultural production, but weeds in orchards are also a problem that cannot be ignored. Weeds compete for nutrients and water in fruit trees, affecting the growth and yield of fruit trees, and also causing great difficulties in orchard management. Therefore, orchard managers need to take measures to control the growth of weeds.

Among them, the use of herbicides is a common method. So, what herbicide to use in the orchard to eradicate quickly and roots?

First of all, we need to classify the herbicide. Herbicides can be divided into two types: non-selective herbicides and selective herbicides. Non-selective herbicides can kill all plants, including fruit trees and weeds, whereas selective herbicides can only kill weeds and have no effect on fruit trees.

Therefore, the use of selective herbicides in orchards is a more appropriate choice.

At present, there are many selective herbicides on the market, such as glyphosate, fluoroxalic acid, glufosinate, etc. Each of these herbicides has its advantages and disadvantages, but the most widely used in orchards is glyphosate.

Glyphosate is a broad-spectrum, non-selective herbicide that kills most herbaceous plants and some woody plants. It has the advantage of killing weeds quickly, and can completely eliminate weeds in a few days. At the same time, glyphosate also kills the root system of weeds, thus preventing weeds from growing again.

In addition, glyphosate has a low impact on the environment and does not pollute soil and water sources.

When using glyphosate in an orchard, there are a few things to keep in mind:

Before using glyphosate, you need to read the instructions carefully and use them according to the method and dosage on the instructions.

When using glyphosate, you need to be safe and avoid contact** and eyes.

When using glyphosate, you need to pay attention to the wind direction to avoid the glyphosate drifting to the fruit trees.

After using glyphosate, it is necessary to pay attention to the observation to avoid affecting the fruit trees.

In conclusion, the use of glyphosate in orchards is a fast, effective, and safe way to control weeds. However, it is necessary to pay attention to safety and proper use of glyphosate when using it to avoid adverse effects on fruit trees and the environment.

Glyphosate herbicides can be used in orchards, leaving no pesticide residues after spraying; Glufosinate-ammonium herbicide can also be used, which will not affect the root system of fruit trees; Acetochlor herbicide can also be used in orchards, which has the characteristics of not being volatile; Alachlor is also a common herbicide and does not worry about weather conditions after use.

After the use of glyphosate, pesticide residues are generally not left on the fruit trees, even if the fruit sprayed with glyphosate is eaten, it will not affect the human body, which can ensure health and safety; Adding an appropriate amount of dish soap to the glyphosate solution can strengthen the efficacy of the drug and cut off the signs of weed growth.

The weeds that grow next to the fruit trees often rob them of nutrients and affect the fruit yield, so what herbicide is good for the orchard, glyphosate is generally used, this herbicide will not cause any harm to the root system of the fruit tree, and it has a very good effect on stubborn weeds.

Acetochlor is one of the most widely used herbicide varieties in the world, the liquid state is pale yellow, it should not be volatile in the sun, and the storage time of acetochlor is up to 5 years, and it will not expire easily; It can remove common weeds such as dogtail grass and wild oats, and the weeds will not regenerate.

Alachlor is also a common herbicide for fruit trees, which has very low harm to humans and animals, is negligible, and is not easily soluble in water, so there is no need to worry about weather conditions; Spraying ahead of time can prevent semi-annual weeds and annual broadleaf weeds.
