For the majority of farmers and friends, in addition to pests and diseases to reduce the yield of crops in their own fields, the weeds that grow everywhere may greatly reduce the yield of crops if they are not removed, and the weeds are rampant to occupy the fertilizer in the land. On this issue, I believe that many friends are very interested in the same way as me, if there is a way to make the land free of weeds, not only save money on buying herbicides, but also have great benefits for the growth of crops.
There is no way to make the land free of weeds, mainly soil, water, oxygen, sunlight and other conditions, weeds can grow in the soil (of course, there are exceptions, such as in the laboratory, or in a vacuum environment, etc., these are experiments carried out under specific conditions, can not be used as a reference), what we are talking about is in the natural environment, obviously it is impossible not to grow a little weeds.
In the process of agricultural planting, growers want to be free of weeds in the field, and we all know that this is impossible, so what can be done is to reduce the occurrence of weeds and reduce the harm of weeds.
In the actual planting process, for different crops, there will be corresponding herbicides, some growers like the combination of pre-seedling closure + post-emergence weeding, some farmers will choose to use post-seedling herbicides alone, and some will be manually pulled.
As for some wasteland or plots without crops, the use of glyphosate and glufosinate ammonium is the choice of most people, in addition, some orchards, lawns, etc., will have weeding machines, under specific conditions, the choice of methods is different.
A friend said that if weeds don't grow on the land, then crops won't grow here, and in some cases, weeds are more vigorous than crops.
Therefore, to sum up, in the natural environment, the situation that no weeds grow on the land is unlikely to occur, if in agriculture, what we need to do is to minimize the harm of weeds to crops.

You can walk more where the grass grows, and the ground will harden after walking, and the grass will not grow on the hardened land, so there will be no grass.

As a graduate of agriculture, grass will grow as long as the external conditions such as temperature, humidity, and light are suitable.

Spray pesticides, pesticides can kill weeds so that no grass grows in the ground.

1. You can first remove the original grass in the land, and then sprinkle lime in the land, and turn the soil frequently, so that the land will not grow grass.
2. The above method is to use lime to produce a chemical reaction with the water in the land to destroy and corrode the nutrients suitable for the growth of grass in the land, which is suitable for the situation that the land does not continue to be used as planting land.
3. If you just don't let grass grow on the surface of the land, you can raise poultry or cattle and sheep on the land that you don't want to grow grass to weed, which is a natural and pollution-free method to make the land not grow grass. Animal manure also makes the land more nutritious and suitable for growing crops.
4. You can also choose to make the land grass not grow through physical 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 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.
