Weeds are very harmful to orchards, what are the common weeds in orchards and the methods of weeding

The general weeds are vine and shrub weeds; If the area of weeds is not large, you can use manual uprooting, if the area is too large, you can use pesticides to spray, or you can use a shovel to turn the weeds into the land, so as to ** fertilizer for the orchard.

After the seedlings grow to five centimeters, they will control the weeds that have not yet been unearthed or just unearthed, and can be mixed with 40 kilograms of sieved soil per mu to make medicinal soil according to the agent and amount used before the seedlings emerge, and then the door is evenly screened on the bed surface with a fine sieve, and the medicinal soil that falls on the seedlings is removed by means of tree strips. When there are many grasses and weeds, the cover grass can be used in the 3-5 leaf stage of weeds with 50-80 ml of emulsifiable concentrate per mu, and the stems and leaves of weeds in wind and rain. If there are broad-leaved weeds or mixed with grassy weeds, 30 ml of 24% fruit emulsifiable concentrate can be used at the 2-4 leaf stage of these weeds, and 4 ml of emulsifiable concentrate can be added per mu to prepare the solution, and a protective cover should be added to the spray head when spraying.

Baimai root, dogtail grass, cow tendon grass, large teff, purslane, can be sprayed with some pesticides appropriately, but be sure to pay attention to the concentration of herbicides and ***.

The grass in the orchard grows vigorously, one day at a time, a few days of hard work will grow very tall, at this time the weeding of the orchard is indeed a very troublesome thing, so some fruit farmers have come up with a once and for all solution: herbicides, this method is indeed time-saving and labor-saving, but it is the most undesirable. In agricultural cultivation, weeding is key.

In addition to the crops, the orchard is also full of weeds.

But people rarely have a good way to get rid of weeds without harming the plants and soil, and people start to think of various ways to get rid of weeds, so what are the best ways? Glyphosate is still used more in orchards, and many fruit farmers are also accustomed to using glyphosate, but if glyphosate is not applied properly, it will cause damage to the root system of fruit trees, and the metal elements in the soil will be fixed. Glufosinate-ammonium is less harmful to the root system of fruit trees and is relatively safe for fruit trees.

Do ecological planting and the like, carry out manual or mechanical weeding.

But the area is large, this practice is not realistic, after all, the weeds grow quickly after being mowed, and they can grow again in 7-10 days, so it is not recommended to mow the grass in large orchards, unless your fruit can be sold very highly. High humidity, grass warblers fly, manual weeding including mechanical weeding is laborious and labor-intensive, labor is not easy to find, chemical weeding is not safe and environmentally friendly, but also harms the soil and fruit trees, how to scientifically and reasonably solve the problem of orchard weeding? In practice, many people have also explored a lot of ingenious methods, when the grass is in contact, only the part that is in contact with the agent is killed, which plays a local killing role, and the plant cannot conduct it in the body.

It can only kill the aboveground part of the weed, and the effect is less effective on the underground part of the weed or perennial deep-rooted weed with underground stems. Such as herbicidal ether, paraquat, etc.

The question of length of time. The problem is that as long as the spray will drift, so the weeding is safe and efficient, the effect is good and does not hurt the soil Why not choose the following methods: manual weeding, orchard grass, weeding and weeding!

Glyphosate herbicide. After the use of glyphosate herbicide, there is generally no residue left on the fruit tree, even after the fruit is ripe, after eating the fruit sprayed with glyphosate herbicide, it will not affect the human body, which can ensure the health and safety of the fruit.

Biocidal herbicides also have a killing effect on the stems and leaves of fruit trees, so it is necessary to avoid splashing the liquid on the stems and leaves. When there is no wind, the nozzle spray is lowered, and a protective cover is added to the nozzle for directional spraying, which can avoid the splashing of the liquid and reduce the damage of the pesticide. Glyphosate and paraquat do not harm the root system.

The residual effect period of soil sealant is long, and improper application will cause damage to the roots, so as to avoid irrigation after application to leach the drug into the deep layer of the soil. Some soil sealants are only effective against broadleaf weeds, and care should be taken when choosing. Mixing or combining the two types of herbicides can achieve better weeding results.

I only know about paraquat and I don't know the rest of the herbicides. I feel like a lot of people use paraquat, and it's very useful.

Manual weeding: From April to September, manual weeding is carried out in combination with cultivators, and weeds are removed with the help of hoes, sickles and other tools, or directly pulled by hand.

Chemical weeding: Buy herbicides, dilute the drug with water, mix it into a certain proportion of the solution, and then spray it with a sprayer.

Machine weeding: Purchase a special weeding machine, which can save labor and effort, and can quickly weed, and can generally use this method for larger orchards.

Mulching and weeding: Mulching or straw in the orchard to inhibit weeding and growth.

1. The most effective method of weeding in the orchard

1. Manual weeding.

1) From April to September, manual weeding is carried out in combination with the cultivation work, and weeds can be removed with the help of hoes, sickles and other tools, or they can be directly pulled out by hand.

2) This method can completely clean up the weeds in the orchard without causing adverse effects on the fruit trees, but the disadvantage is that it is time-consuming and labor-intensive.

2. Chemical weeding.

1) Buy herbicides in pesticide stores, then dilute the drugs with water, mix them into a certain proportion of liquid medicine, and then spray them with a sprayer.

2) This method has less work and can quickly control weeds, but it is easy to cause pesticide damage if used improperly, and long-term use will also enhance the resistance of weeds.

3. Machine weeding.

1) Purchase a special weeding machine, which can generally be used in larger orchards, which has the advantage of saving labor and effort and can quickly weed.

2) The disadvantage of this method is that the input cost is larger, and the weeder can only remove the upper part of the weeds, and the weeds in the corner still have to be manually cleared.

4. Mulching and weeding.

1) Cover the orchard with mulch, weeding cloth, or evenly cover a layer of straw and straw with a thickness of 6-8 cm to inhibit the emergence and growth of weeds.

2) The use of this method can not only achieve the purpose of weeding, but also play the role of heat preservation, moisturizing, fertilizer and moisture preservation, which is conducive to promoting the growth of fruit trees.

Second, the role of weeding cloth

1. Inhibit the growth of weeds.

After covering the weeding cloth, the weeds cannot get sunlight and therefore cannot photosynthesize, and after a period of time they die.

2. Increase ground temperature.

The weeding cloth can absorb sunlight and block the heat from the ground from dissipating outward, so as to achieve the effect of heat insulation.

3. Water and fertilizer retention.

Weeding cloth can reduce the evaporation of groundwater, and in the rainy season, it can also prevent the soil from being washed away by rain, reducing nutrient loss.

4. Reduce pests and diseases.

Weeds on the ground are the main overwintering sites for pests and germs, and covering with weeding cloth can prevent weeds from growing, thereby reducing the base number of pests and pathogens.

The weed control of orchards should be based on chemical weeding, and various means should be comprehensively used according to the ecological and environmental conditions of different regions, such as mechanical cultivation, intercropping, grass method, and mulching to cover the surface. This can reduce the amount of herbicide used, reduce the degree of environmental pollution, protect natural enemies and the ecological environment, and increase revenue and reduce expenditure.

Many fruit farmers have explored some feasible methods in production practice, such as the intercropping of fruit vegetables, fruit grains and fruit beans for young orchards, which not only increases income but also reduces the area of herbicide application. Planting leguminous forage grasses such as alfalfa and white clover between the rows of fruit trees can inhibit the growth of weeds, increase soil nitrogen fertilizer, and can also be used as livestock feed. Cultivating Poaceae between the rows of fruit trees has a good inhibitory effect on the growth of weeds.

Mulching the rows of fruit trees with field wastes such as wheat straw is also one of the ways to control weeds. In areas where labor is scarce, the use of mechanical tillage for weeding is also an effective method.

Laying of anti-weed cloth. Laying weed-proof cloth between the orchard rows can effectively inhibit the growth of weeds, and greatly reduce the fatigue and lack of time for manual weeding. Environmental pollution caused by herbicides can also be avoided.

But there is one problem that cannot be avoided, pie does not fall from the sky, and laying straw cloth in the orchard is not a small expense. The effect can but requires manual maintenance later to prevent trampling and damage. Orchard management machine.

Orchard managers are a good way to do weeding. No herbicides, energy saving and environmental protection, small investment.

It is managed two to three times a year with almost no grass damage. Weeds in the orchard, in addition to plant diseases and pests, is also a headache, too many weeds point out the fertility of the land, if it is not clear, it may greatly reduce the crop yield, and a lot of trouble, will use a large number of herbicides to deal with it, but herbicides are chemicals, long-term use will cause pollution of the land, and even agricultural products will have drug residues, therefore, spraying herbicides is not an effective method of weeding.

An effective way to protect the environment is: cover it with plastic sheeting: on the ground of the orchard, cover it with a thick layer of plastic sheeting to cover the ground under the fruit trees, so that the grass on the land will not grow, it can also kill the grass buds, and it can also maintain the temperature to provide temperature and retain moisture for the growth of the fruit trees.

Cultivating and weeding: Some people continue to cultivate the land after autumn to increase the softness of the orchard soil, so that the weeds rot and become fertilizer to remove weeds. Manual mechanical weeding:

Small and medium-sized weeders can be used for manual weeding.

Poultry such as chickens and ducks can be raised in the orchard to reduce the production of weeds, and the excrement of poultry can also be used as fertilizer for the orchard, and the dead weeds with seeds in the orchard can be removed in time to lay the foundation for weeding in the coming year. The development of orchard weeding is really a headache. Manual weeding is too troublesome, and the orchard can use less manual weeding.

If the orchard area is large, manual weeding is too late, and the effect is not ideal. The use of herbicides has a good effect, a good effect of saving labor and effort, and it comes quickly. But there are also pros and cons.

Herbicides are effective, but they can pollute the environment and pollute the soil. Long-term use can also affect the quality of the fruit. So is there a way to get rid of weeds without using herbicides that is both environmentally friendly and easy.

Weeding can be done with a weed-proof cloth.

The purpose of weeding is to help plants grow, and weeds in the field will compete with crops for nutrients if not removed in time. The use of herbicides can effectively kill weeds, but it will also produce pesticide damage, which not only destroys the ecological environment, but also absorbs the residues on crops by the human body, which is harmful to the human body.

The use of weed-proof cloth is a green, healthy and environmentally friendly way of weeding, which will neither damage the ecological environment nor cause harm to the soil.

After covering the weed-proof cloth, it can improve the soil environment, not only has a good inhibitory effect on weeds, but also moisturizes and retains fertilizer, breathes and seeps, will not cause harm to the orchard land, and will not produce chemical pollution!

It can also be covered with black film for weeding, or it can be weeded manually, but it is more troublesome.

Weeding can be done manually. Use a hoe every other month to get rid of the weeds under the fruit trees, which can also help the fruit trees loosen the soil, which is pollution-free.

Covered with black mulch, it has good weed inhibition, and it is very prominent in the weed growth stage of the orchard, especially in the apple orchard of the small tree that has just been planted, it must be covered with black mulch.

Weeding with a small rotary tiller is OK.

The orchard is now a dozen acres, or even dozens of acres, at every turn. The scale is larger, because the area is smaller, the income of the fruit farmers is less, and if there is a bad year, the fruit farmers are not guaranteed. Or a bumper harvest but can't sell at a good price.

The main reason for the lack of income is that the quality of the fruit cannot be improved, and there is no pricing power. Therefore, fruit farmers want to increase both production and income.

First of all, to ensure the greening of fruits, then no pesticides can be used, including herbicides to remove weeds in orchards. Herbicides are very powerful, and in addition to removing weeds, they are also harmful to the soil and other plants and fruit trees. On the surface, it does work quickly and economically.

But in the long run, it is the growers who will suffer. Herbicides can compact the soil and be absorbed by fruit trees, and pesticide residues can last for more than five years. Remove every year, grow every year, and increase the amount of herbicides every year.

Do you think the soil can stand it? Moreover, the amount of fertilizer applied is increased every year. It has virtually increased investment and affected the quality of fruits.

Nowadays, many fruit farmers think that weeds will absorb nutrients from fruit trees, and they all hope that their orchards will not grow a single grass. Imagine that when the soil does not grow any grass plants, do you think such land can still be used? Originally, the symbiosis of plants and trees is the law of nature.

Grass in the orchard actually has many benefits. 1. It can keep warm, and the soil under the grass is moist in high temperature weather, which can preserve the moisture of fruit trees. 2. It can naturally fertilize fruit trees, and it becomes fertilizer for fruit trees after the grass dies every year.

3. It can be used as auxiliary feed for poultry.

If you really want to get rid of it, manual weeding is recommended. While this will increase your investment in the short term, you will increase your unexpected income in the long run. The method of stopping the seed can be used.

1. The grass in the canopy remains. Moisturizing, heat preservation, fertilizing. This is because most of the root system of fruit trees is within the canopy.

2. The use of agricultural machinery is fast and labor-saving. 3. Engage in some breeding under the fruit trees, put some chickens, geese and other animals to weed, and the manure is a good organic fertilizer.
