Is there any way to stop grass growing on the land?

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.

The land is extremely polluted.

The geographical environment makes it impossible for all living things to survive. I think that the seeds that do not grow in the ground are the quality of the seeds, and the soil is the problem. The cause of the soil, the soil is too dry, or too wet, which is not conducive to the absorption of water and nutrients by crops, so it does not grow.

The solution is to water the soil that is too dry frequently to keep the soil moist and ensure the water needed by the crops. Excessively wet soil should be ridged and ditched for drainage. Pesticide.

When using pesticides, we should use them in strict accordance with its instructions for use, do not increase the concentration without authorization, and use drugs according to the disease.

1. The fields are full of crops.

Weeds and crops grow at the expense of the other, and when crops grow vigorously in the field, weeds will be genus.

Control, because the crop grows vigorously, not only has a strong ability to absorb nutrients, but also can block the sun from irradiating weeds, weeds can not get sunlight under the crop, and will gradually wither, but this is not absolute, often the ability of weeds to compete for glory and fertilizer is stronger than that of crops.

2. Biocidal herbicides.

Generally refers to glyphosate, glufosinate, etc., now take glyphosate as an example to illustrate, glyphosate for all kinds of weeds are more effective, and can die roots, after spraying glyphosate, can control weeds for about 20-30 days, later or need crops to control weeds.

3. Industrial herbicides.

The more famous is metsulfuron, this herbicide is effective on large trees, and after spraying metsulfuron, it can control weeds for about 2-3 years, so metsulfuron is forbidden to be used in cultivated areas, generally in wasteland, away from water sources. Another herbicide is cycloazinone, which can be used to eliminate weeds such as bamboo, and is also an industrial herbicide.

4. Cover with bark or leaves.

Spreading a layer of mulch on the soil surface can inhibit the growth of weeds and can retain moisture in the soil, which is conducive to the cooling of the roots, which is very beneficial for the growth of plants.

5. Remove with cleaning substances.

Common bleach, vinegar and baking soda can remove weeds, they can be sprinkled directly on the place where weeds grow, and they are especially effective in killing weed seedlings, but they are generally used to remove weeds in rock crevices.

After weeding, spray with a variety of herbicides separately to avoid regeneration.

It's OK to turn the land into a desert.

Spread a layer of fine sand on the surface, so that it has an inhibiting effect.

Rip off the ground!

This is also a philosophical answer.

Sprinkle with quicklime and salt, then water or wait for rain.

If you are tamp, the seedlings will not be able to get out.

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.
