CATDOLL : CATDOLL: I find that there are very few earthworms in the fields now. Why is that?

Now I find that there are very few earthworms in the fields. Why is this?

Earthworms are annelids, and they mainly feed on humus in the soil. Earthworms are also called earthworms. According to the Compendium of Materia Medica, earthworms are also a kind of Chinese medicinal material in Chinese medicine. The excrement of earthworms is a good fertilizer. In soils that are fertile and rich in organic matter, the number of earthworms is also large. Earthworms can move slowly in the soil and do not eat the roots of crops, so they do not affect the normal growth of the roots of crops. On the contrary, the feces excreted by earthworms provide good nutrients for crops. The loose soil and good air permeability will significantly increase the yield of crops.

I don't know when it started, but the earthworms in the farmland are getting fewer and fewer. Many fishing enthusiasts like to make earthworms into bait to catch big fish. Therefore, fishermen call earthworms fishing worms. In the past, you could find thick, long and fat earthworms in the fields. Now the earthworms in the fields seem to be hidden more tightly. Occasionally, there are earthworms, but they are obviously thin and small. Earthworms have the ability to regenerate after being cut off. Theoretically, earthworms can become two individuals after being cut off. Will there be more and more earthworms? Unfortunately, the earthworms in the soil are not increasing as we imagined, but are decreasing. Why is this? Who should we blame?

1. Pesticides are rampant. my country's rapid economic development in recent years and extensive development will inevitably bring about bad consequences that we do not want to see. Environmental pollution and soil pollution are all urgent problems that need to be solved. Fortunately, the state has been very practical in this regard. The large-scale use of pesticides and fertilizers has caused excessive pesticide content in the soil. Large amounts of fertilizers have caused the soil to become compacted and the air permeability to deteriorate. Such an environment has brought great challenges to the survival of earthworms. Therefore, earthworms will appear less and less in the soil.

2. The degree of soil acidification increases. Long-term and large-scale application of chemical fertilizers will cause the soil to become acidic, and earthworms cannot adapt to it, so their number can only decrease.

3. Insufficient organic matter content. With the quickening pace of life, agricultural crops are no longer the only option for farmers to survive. In order to earn more money, capable people have gone out to work. Due to the lack of strong labor, less and less farmyard manure is applied to the fields. The soil lacks organic matter and is no longer as loose as before. Without food, earthworms have a sharp decline in number.

4. Excessive application of pesticides and repeated cropping for many years have led to frequent pests and diseases. In order to control pests and diseases, highly toxic pesticides are flushed into the fields. While preventing and controlling pests and diseases, earthworms are also killed. Farmers use highly toxic pesticides to fight pests and diseases, but in the end, earthworms are the losers.

Knowing these reasons, everyone must also know how to improve soil fertility and increase the number of earthworms in the field:

1. Increase the application of organic fertilizers. Farmyard manure is stable and rich in organic matter. It is a good food for earthworms. If it is used as base fertilizer every year, the number of earthworms will gradually increase. In the soil, increase the use of beneficial microbial fertilizers.

2. Reduce the use of pesticides, especially some highly toxic pesticides. Try not to use them. If pests appear in the fields, in order to prevent and control the pests, try to choose pesticides that are highly effective and low in toxicity, or choose biological agents.

3. Return the straw to the field. This should be done for several years. The organic matter content in the soil will increase and the soil will gradually become fertile. Planting green manure is also one of the foods that earthworms like. Well, that’s all for today’s sharing. Welcome to follow us. If you like it, please give a thumbs up before leaving.

Because people spray a lot of pesticides when they farm, the earthworms are killed.

Because now farmers will add some fertilizers and pesticides to ensure the quality of crops. In this way, a lot of fertilizers and pesticides will remain on the land and penetrate into the soil. Earthworms live on soil, so many earthworms are poisoned to death by pesticides.

It is found that there are more and more pesticide residues and heavy metal residues in the fields. The toxic and heavy metal pollution in the fields is becoming more and more serious, making it increasingly difficult for earthworms to survive in the fields, so there are fewer and fewer of them.

If you find that there are fewer earthworms in the field, then it must be a problem with the soil, because earthworms need good soil to survive.

What kind of animal can burrow into the soil? Is it similar to Tuxingsun?

It is an earthworm, or a field mouse or a subway. Thanks for accepting my answer.
