How to make the land grass free and at the lowest cost

Herbicide spraying should be in high temperature, dry, windless, sunny weather, 10 a.m. to 4 p.m. Experiments have shown that spraying herbicides at wind speeds of more than 8-10 m/s can reduce the efficacy of herbicides by about 5%. In case of rain 6 hours after application, the efficacy of the drug will be reduced, and it should be properly sprayed.

corn herbicide).

The soil should be kept moist before and after spraying to improve the efficacy. After the application of pesticides, pay attention to drainage if it rains to avoid pesticide damage.

I seem to have seen a philosophical question before, and it is also like this, which says: The best way to keep the land from growing grass is to plant crops, which is actually quite practical d can be sold after harvesting and saving costs Hehe.

If you mash the battery and put it on, Enyin shouldn't have grown anything, and it won't cost a few dollars.

Raise a few cows from local materials.

Stone wooden, sealed with cement.

Buying a little lamb is environmentally friendly and profitable

Sprinkle with lime.

But you don't know what this question is for.

When it was time for the peasants to plough in the spring, the seeds that had been sown sprouted, and the grass in the field also sprouted, and the weeds in the field also sprouted.

growth, will absorb a part of the nutrients of the land. The problem of growing grass in the field is the most worrying thing for the farmer's uncle. The harm of weeds is great, and the impact of weeds is greater than that of pests, which is an important hazard to crops. So how can we stop grass from growing in the field? <>

When it comes to weeds, many people would recommend using herbicides.

But this is not a long-term solution, herbicides are chemical agents that, if used for a long time, will not only damage the land, but also cause air pollution. This is not feasible for farmers who have been farming for a long time. Once the land is damaged, the grain production will be greatly reduced.

There is a high probability that a year's hard work will be wasted. <>

It is suggested that if you are planting an orchard, you can use a thicker plastic sheet to cover it, and there are more weeds in the orchard, because the fruit falls to the ground in autumn, which is equivalent to fertilizing the land once, and the growth rate of weeds is greater than that of ordinary cultivated land when the land is nutritious. Spread a thick plastic film on top of the weeds, the weeds will not grow, and it will also maintain the temperature of the land, the plastic will not reflect the sunlight, and the fruit trees will receive enough sunlight, and the fruits will be bigger and sweeter. This method not only reduces weeds, but also supports increased yields, which is considered a good idea.

Some studies have also found that there is a chemical fertilizer on the market. This fertilizer not only keeps the weeds rotting on the ground, but also makes the land more fertile, and the rotten grass fertilizes the land. When ploughing the ground in autumn, sprinkle some chemical fertilizer, the next year's land will not grow grass, and the step of fertilizing the land is omitted.

Chemical fertilizers also do not pollute the air and do not cause damage to the land. This method is suitable for ordinary arable land. Remember that the land needs to be maintained, and any fertilizer is available.

You can remove the grass from the land first, then sprinkle lime on the land, and turn the soil frequently, so that the land does not grow grass.

Choose to keep the land grass-free by physically mulching. The land is covered with plastic film, straw or other hay to reduce the sunlight or air of the covered land, thereby inhibiting the growth of grass and achieving the effect of weeding.

The use of lime and the water in the land to produce a chemical reaction, the soil is suitable for the growth of nutrients to destroy and corrode away, suitable for the land does not continue to be used for planting.

Weeds can be pulled out regularly, or the soil can be ploughed regularly, and some herbicides can be sprayed.

We can spray some herbicides on the land, or use some chemicals, these methods can inhibit the growth of grass in the soil, which can better protect our crops, or use a weed wedge to clean up the grass on the land.

I think you can sprinkle some salt, sulfuric acid, lime, vinegar, or chemical fertilizer on the land to stop grass from growing on the land, because the land environment has been polluted.

You can use herbicides, then you can let poultry plants or sheep graze, you can raise chickens or ducks in the area, or you can choose to physically cover it with a layer of plastic wrap.

Is there any way to keep the land from growing weeds? Most plots with a large amount of grass have formed a vicious circle, and the growth of grass is increasing year by year. Except for some grasses that can basically survive the winter, most of them are due to the maturity of various grass seeds in the previous year, which were not removed in time, and many people even want to use withered grass as fertilizer.

1. Find natural enemies of weeds for weeding. This method is relatively simple, that is, to find the natural enemies of weeds, plant this crop in a place where there are many weeds, and achieve the purpose of weeding through the incompatibility of plants and the use of two opposing characteristics. For example, planting sunflowers can remove purslane.

Sorghum can remove the big mango, and mango can remove the bamboo whip. It is believed that this method has been used by many people. It is based on the principle of mutual restraint and killing among living beings.

2. Cover with thick plastic sheeting. This method is suitable for orchards. There are many weeds in the orchard.

Covering the ground under fruit trees with plastic sheeting can not only cover the land so that the grass cannot grow, and many young grasses will be killed, but also maintain the ground temperature and provide temperature for the growth of the fruit tree. Reflected radiation can enhance the radiation of fruit trees, which has a good effect on the sweetness and ripening of fruits. Use opaque sheets.

Such as canvas, black plastic sheets, wood, etc., cover the crop ridge with opaque items of size and other areas. When planting crops after spring ploughing, the ridges of the crops are generally covered together in order to cover the unearthed grass, so that the grass does not get light and has no photosynthesis.

The grass is difficult to grow and slowly dies.

3. Chemical fertilizer weeding. Scientific experiments have shown that certain amino acids.

Not only can it remove weeds, but it can also improve soil fertility. Some people continue to plow the land after the fall, which allows the weeds to rot and turn into fertilizer, which completely removes the weeds. In many agricultural fertilizers, there are many amino acids, a class containing amino and carboxyl groups.

A general term for organic compounds. It has a good effect on the growth and nutrition of plants. At the same time, it also has a weeding effect. Fertilizers rich in amino acids can be used more for crop field management.

Frequent renovation of the land is a very good way to keep the land free of weeds, remove the roots of the weeds, and eliminate the weeds at the source. In addition, herbicides such as paraquat are sprayed with the help of chemicals to keep the land free of weeds.

Pesticides can be sprayed, cleaning can be done on time, and food cannot grow on land that does not grow weeds.

Herbicides can be used to control weeds. Manual weeding can also be used. Just after the rain or just after watering, use a hoe to go to the surface of the slippery ground to get out the grass.

1. Weeding frequently.

2. Grow crops on the land.

3. Use glyphant.

4. Make the land into a concrete floor.

5. Sprinkle sodium coltan to ensure that no grass grows.

Only by planting crops can weeds not grow in the field.

In a broad sense, weeds are defined as all plants that grow on sites that are detrimental to human activities or harmful to production sites. It is mainly herbaceous, but also includes some small shrubs, ferns and algae. There are more than 300,000 species of plants that have been named in the world, and about 8,000 species of plants that have been identified as weeds. There are more than 36,000 plant names that can be found in books and periodicals in China, and more than 1,200 kinds of plants in 119 families are identified as weeds.

In addition to being classified according to botanical methods, it can also be divided into aquatic, swamp, wet and xerophytic according to its adaptability to water, and can be divided into grasses, sedges and broad-leaved grasses according to the needs of chemical control, and can also be classified according to the nutritional type, growth habit and reproduction mode of weeds. Its biological characteristics are as follows: many modes of propagation, strong reproduction and regeneration, life cycle is generally shorter than that of crops, mature seeds fall with maturity, strong resistance to stress, and high photosynthesis efficiency.

The main pests of farmland weeds are: competing with crops for nutrients, water, sunlight and space, hindering field ventilation and light transmission, increasing local climate temperature, and some are intermediate hosts of pests and diseases, promoting the occurrence of pests and diseases; Parasitic weeds absorb nutrients directly from the crop, reducing the yield and quality of the crop. In addition, the seeds or pollen of some weeds contain toxins that can poison humans and animals.

Farmland ecology is affected by both nature and tillage, and the groups and occurrence dynamics of weeds are different, and it is often difficult to obtain a good control effect with a single weeding measure. At the same time, various methods of weed control also have their own advantages and disadvantages. Comprehensive prevention and eradication is to comprehensively use the complementary and coordinated effects of various measures according to local conditions to achieve the goal of efficient and stable prevention and elimination. For example, chemical control measures can be used to control weeds in the early stage of crops, combined with cultivation management to promote crop growth advantages, which can inhibit the weeds that occur in the middle and late stages of crop growth. In tea, mulberry, orchards and rubber plantations, perennial weeds can be controlled with conductive herbicides, and the continuous occurrence of weeds can be inhibited by planting green manure to cover the surface.

Since the 70s of the 20th century, some countries have carried out comprehensive management of diseases, insects, weeds and other pests on the basis of ecology, studied and explored the occurrence of various types of weeds and the threshold of economic losses under certain tillage conditions, and organically combined various weeding measures according to the place and time to create a reasonable agricultural ecological system, which is possible to control the occurrence of weeds and the degree of harm within the minimum limit to ensure the continuous high yield of crops.

1. Methods of chemical weeding of cultivated land. If it is arable land, herbicides can be selected according to the crop for closed weeding and post-seedling stem and leaf treatment. Generally, corn fields can be used for closed weeding, or with z-chlor and thiensulfuron-methyl closed weeding, or nicosulfuron and atrazine can also be used for post-emergence weeding.

If it is a soybean field, it can be used for closed weeding such as prochlor and thiensulfuron, and it can also be treated with quinoxalin and flusulfafen stems and leaves. If it is other crops, you can choose suitable pesticides to spray weeds according to different crops.

Second, the method of tillage and weeding. The principle is to implement the combination of deep ploughing, rotary and harrowing of the land through a reasonable land rotation system and scientific farming, and at the same time, it is also necessary to combine it with shoveling to carry out manual weeding in a timely manner. The process of weeding is indispensable, whether it is manual weeding or machine weeding, as long as the purpose of weeding can be achieved.

However, the effect of manual weeding is the best, the general farmer planted his own vegetable plot is not large, if you have time, you can use a hoe to weed, the effect will be more obvious.

3. Other methods of chemical weeding of land. In the case of woodlands and other abandoned lands, paddy fields and ponds, etc., we can use herbicides to use gray grass. For example, herbicides such as Roundup, Grass Dry, and Glyphosate can be used for incidal weeding.

However, if it is woodland, do not spray it on the trees to avoid causing harm to the trees. If it is a paddy field ridge, you must pay attention to the medication, Ke in windy weather, the medicine is that the nozzle should be close to the pond ridge, not too high, to rabbits to cause rice pesticide damage.

Fourth, first remove the grass seeds from the land. We all know very well that if weeds need to grow, there must be seeds and an environment to grow, and if we can remove weed seeds, we can naturally reduce the growth of weeds. The seeds of a wild grass are very reproductive, and as long as there is the right rain and temperature, it can grow a large area.

Therefore, it is necessary to remove weed seeds in a targeted manner.

5. The land is covered with straw or mulch. The function of mulch is like the quilt we sleep on, which can increase the temperature and control the moisture of the soil, and the high temperature environment is not suitable for the growth of weeds, so as to achieve the purpose of controlling their growth. The purpose of mulching straw is the same as mulching, but no matter what kind of thing it is, it should not be mulched on the land for a long time, otherwise it will also affect the growth of crops.

Plough the land and use pesticides. The best way is to plough more land or weed, if too many pesticides are used, the crops will not meet the requirements, and the pesticide content is too high.

Herbicides can be sprayed on the land on a regular basis, so that the weeds can be easily eliminated and continue to be sprayed when the weeds want to grow.

The weeding effect can be achieved by hoeing and plowing the land. Another convenient way is to apply pesticides to the land regularly to avoid weeds.

It is generally impossible to achieve, even with the use of pesticides, after a period of time after the effect has passed, weeds will still grow; It can be planted with mulch, but the cost will increase accordingly. In addition, it is manual weeding, which will be less after many times of finishing.

Lack of water, lack of fertilizer, the use of herbicides, etc., strong acid, strong alkali is also feasible. Plant growth requires some necessary conditions, while rejecting some harsh conditions. This can be achieved by depriving the soil of the conditions necessary for plant growth, or by creating harsh conditions.

Chemical weeding after sowing to before emergence is the method of using time difference selection method to weed, which is sprayed with herbicides after soaking seeds and before the seedlings are unearthed, and weeds germinate early, and will die quickly after encountering pesticides to achieve the purpose of weeding. The commonly used chemical weeding methods for sorghum fields and before seedlings after sowing are:

1) 25% green melon wettable powder, 200 grams per 667 square meters, 300 grams, mixed with 50kg of water, evenly sprayed on the soil surface.

2) 25% green melon wettable powder, 150 grams per 667 square meters, plus 150ml of 50% herbicidalan EC, or 50ml of 60% butachlor EC, mixed with 45kg of water, sprayed on the surface of the soil.
