The silt cleared out of the fish pond is said to be cool, and the crops do not like to grow, how to

Born in the 80s and growing up in the countryside, more or less understand the use of pond silt as farm fertilizer, and the application of pond silt to the soil to increase the fertility of the land, which is conducive to the growth of crops. At that time, the utilization rate of farm manure was very high, and people often used pond mud to make organic fertilizer. At present, the sludge of high-density aquaculture ponds, fish ponds, especially fish ponds, is rich in organic matter, which is mainly caused by fish manure and feed residues and sediments.

It is a very good fertilizer and a good choice as a farmyard fertilizer. However, some people will find that if such pond mud is directly applied to the field, it cannot play the role of farm fertilizer, and it is often counterproductive and not conducive to the growth of crops. The reason is that the sludge cleaned up from the fish pond is rich in organic matter, similar to "raw manure", and needs to be properly treated in order to become a high-quality organic fertilizer.

In fact, the sludge from the fish pond contains a large amount of fish excrement and some feed residues, etc. Since fish excrement and feed residues are mostly organic, they can be detected by some microorganisms or even parasites.

Decomposition survives, so the sludge at the bottom of the fish pond also contains a large number of microorganisms and bacteria. A large number of microorganisms live and breathe in the silt at the bottom of the fish pond, they need to consume a lot of oxygen in the water and can seriously affect the growth of fish.

As a result, many fishponders use quicklime after pumping out the fish at the end of the year.

to clean and disinfect the silt in the fish pond. Due to the long-term deposition of fish ponds, fish excrement and feed waste, the sludge at the bottom of the fish pond not only ages, but also increases the oxygen consumption of the pond, releases toxic and harmful gases, and breeds a large number of microbial parasites, which has a great impact on the fish pond.

Therefore, it is necessary to carry out sludge clean-up work in fish ponds. General sludge amendments do not have much effect, and the most effective way is to dig out the sludge. The dug pond mud should be said to be a very good fertilizer, because the pond mud contains a lot of organic matter, especially nitrogen, phosphorus, potassium, which are all nutrients necessary for the growth of crops.

It can be said that it is very beneficial to the growth of crops.

First of all, the mud can be exposed to the sun and cracked, and then after the rain, then the silt soil will naturally mature, and it can be used for cultivation normally in the future, and secondly, the silt can be pumped to the flat ground before winter, blocked with soil, do not let the silt flow away, and then after low temperature freezing and sun exposure, it can be cultivated normally next year.

You can dry the pond mud directly by the pond, or pull it to the field to dry the pond mud, and finally close the compost pile with pond mud or fine soil to make a farmhouse manure fermentation pile and let it fully rot.

In such a situation, you should retranslate the soil, and then add some fertilizer, which can have a good effect.

The sludge removed from the fish pond cannot be used directly for crop cultivation because the sludge is rich in fish excrement and various plant decay materials, and has a strong fertility. If it is used directly in crop planting, it will burn the seedlings due to excessive fertility, resulting in the death of the crops. In addition, because the sludge contains various bacteria and microorganisms, direct fertilization is easy to produce pests and diseases, resulting in reduced crop yield.

Of course, you can, because the sludge contains fish excrement and uneaten feed, which falls in the mud and after a long fermentation, it is very nutritious and can make the crops grow better.

The fish soil leached in the fish pond can be used to grow crops, because there are many microorganisms and fish in the water, and there is a large biosphere, and they will discharge their own fertilizer, which will form nutrients in the land, so it is said that crops can be grown.

Yes, these silts used to raise some fish, so there are many fish excrements in it that are more nutritious, and it is easier to grow crops more.

Silt is perfectly used to grow crops, but it's also a good fertilizer, with fish excrement and a variety of algae, which is rich in nutrients.

Answer: Pond soil is humus containing a certain amount of organic matter, which has been deposited in ponds or fish ponds for a long time; The pond soil is rich in residues, fish and shrimp droppings, duck and goose droppings, rotting branches, dead leaves, weeds and reeds, as well as toploam containing humus material washed down by rainwater; The longer the pond siltation time, the darker the soil color of the pond and the higher the fertilizer energy. The soil in the pond is like a pile of compost under water. After years of humic acid accumulation, it has become a complete organic fertilizer with comprehensive nutrition and rich nutrients. Among them, the content of nitrogen, phosphorus and potassium is the highest, and other trace elements are also balanced; There used to be a saying in the countryside:

To grow crops well, one season of pond mud, two seasons of fertilizer"; This proverb has two main meanings; First, pond mud is used as the base fertilizer for planting crops, and one season can play a fertilizer effect in two seasons; There is also a meaning that if you want to use pond silt as fertilizer for growing crops, you need to make adequate improvements to the pond silt collected. This improvement process takes time and can be used when planting crops in the second season, so that the fertilizer can be fully utilized. Although this mud has been accumulated for a long time, its nutritional value, fertilizer composition, and organic fertilizer are still relatively high.

But it can be present and contain a lot of bacteria, and this problem is unavoidable. So on this issue, almost no one wants to clean up the mud in the countryside. This is the main reason, but what we want to use is very simple, it needs to be exposed to the sun and then disinfected with quicklime.

Basically, if the weather is good, spread out the mud and dry it. Once the water inside has evaporated, it is ready to use. But you can't put too much fertilizer, and if you put too much fertilizer, it will cause a lot of problems.

Farmers in rural areas generally do not use the sludge removed from fishponds. Why not? One of the important reasons is that there is no waiting time, because the exposure time is too long, and it takes a month or two months to be fully sterilized after the race.

So for this problem, even if the sludge from the fish pond is cleaned up in the countryside, it will not be used easily, because if the crops are not mastered well, there may be more problems, which may cause various chain reactions.

Pond soil is a good fertilizer for fertile land. However, pond soil is used as fertilizer, and it needs to be improved into high-quality organic fertilizer in order to play the role of fertilizing and nourishing the soil."

Many farmers choose to breed fish ponds to make a fortune, so what other uses can be used after the silt in the fish pond is cleaned up? Let's **** together. If there is too much silt, the amount of water in the pond will be reduced, which is harmful to the fish farm.

In the past, when there was no chemical fertilizer, the silt from the fish pond could be used as fertilizer to irrigate the fields, and this sludge was rich in trace elements.

and organic matter, which can be used as fertilizer for crop growth after decaying in water.

When used as fertilizer, the sludge is not directly put into the field, but is processed by the farmer. Because there are heavy metals or some pathogenic bacteria in the newly cleared sludge, these toxic and harmful substances, if directly used in crops, may have adverse effects on human health. There is a lot of organic matter in the sludge, especially nitrogen, phosphorus and potassium.

These are very high levels, and these are the nutrients that crops need, so it is said that silt can be used as fertilizer for crops.

The untreated sludge is very sticky, and if it is directly spread in the field, it is easy to cause the sludge to harden on the soil of crops after drying, which will affect the growth of crops and lose the role of silt fertility. Moreover, the fertility of these sludges is particularly large, and if they are not treated and used directly, it will also lead to the burning of seedlings of some crops because they are not tolerant to fertilizer.

Therefore, the soil dug out of the fish pond should be dried until it is dry, and after drying, the silt can be used to cover the dry straw and cow dung, and then leave a gap for ignition. As the fire grows bigger. As the burning becomes more concentrated, some of the gases burned by the straw and cow dung will be absorbed by the sludge on it, and when these things are burned, the soil can be shoveled away, and then the manure water can be used to add a little plant ash.

Once saved, it can be used to irrigate crops. This method of burning and drying can remove the coolness of the sludge and turn the useless sludge into a fertilizer for crops.

This sludge can be used as farmyard fertilizer, as it is rich in organic matter, which can be evenly mixed with crushed straw and used after proper decomposition.

In such cases, if you want to treat it effectively, dry the silt as much as possible, and then burn the manure.

The fish pond can be cleaned, or treated according to the properties of the soil, and the silt can be removed.

The sludge at the bottom of the fishing pond is not only the sludge that has been blistered by small water, but also the excrement of aquatic plants and fish that have rotted into mud for a long time. Therefore, the sludge soil at the bottom of the fishing pond has a variety of organic matter and elements such as phosphorus and potassium, but because it is soaked in water for a long time, the nitrogen content of the sludge soil is low. The sludge at the bottom of the pond is very low in nitrogen and the sludge is not sufficiently alcoholized.

Infinitely close to "raw manure", if it is used to grow crops, not only is it not conducive to the growth and development of crops, but because of the environmental temperature formed by its secondary fermentation, it will cause harm to crops. As a result, food crops grown on the soil here do not like to grow. Through a winter of wind and sun, freezing and freezing, the whole process of natural fermentation is virtually completed.

In addition, many diseases are also cold to death by prolonged ultra-low temperatures. Waste such as manure and concentrate feed of fish fingerlings in fishing ponds accumulate over a long period of time.

As a result, the sludge at the bottom of the fishing pond not only senesces, but also increases the oxygen consumption of the pond, releases toxic and harmful gases, and many microbial species of schizocephalic larvae grow, which is very harmful to the fishing pond. Therefore, it is necessary to carry out the sludge cleaning work of the fishing pond, the effect of the general sludge bread improver is not too large, and the most effective way is to dig out the sludge. The sludge is made from the living soil and fertile soil washed out by precipitation in the fields, which contains a lot of organic matter, plus fish fingerlings in the ponds and ditches, and the excrement left by the ducks and geese raised by each family in the ponds.

Therefore, it is also a better chemical fertilizer in the field, in the countryside of Jilin Province, in the stage of the production team, each production team is doing this, because the organic fertilizer has not been applied at that time, this way, not only to remove the sludge of the fishing pond and ditch, but also to solve the phenomenon of shortage of chemical fertilizer in the field, therefore, the sludge cleared out of the fishing pond is to wash out the field with the organic matter of the organic matter of the living soil, fertile soil, cooked soilThis kind of will not have any problem of cool soil, and it will promote the growth and development of food crops!

You can loosen the soil in time, and then you can put more earthworms, and then you have to put in some fertilizer. Then be sure to let the sun shine more.

Crops do not grow because the soil in the field has been damaged, and some garbage can be cleaned up properly, as well as some irrigation and fertilization of the soil, so that the soil can be guaranteed to get nutrients.

The silt cleared out of the fish pond is an important part of farm fertilizer. Because silt soil is rich in organic matter, it is actually a good fertilizer for crops. The only thing to be aware of is that adding a lot of silt will make the soil very sticky.

If the soil is too sticky, it is not conducive to root respiration for most crops. So I suggest that you don't add a lot of silt directly to the ground. First, the silt soil is evenly mixed with the crushed straw, and after it is properly decomposed, the dense viscosity of the silt is changed.

When it becomes more loose and breathable, it becomes a highly fertile organic fertilizer.

Summary. If the fish pond has not been treated for many years, it can lead to excessive sediment accumulation, and traditional dredging methods alone may not be effective, or require more effort. In this case, you can consider using professional fish pond dredging equipment and technology, such as slurry separators, sludge removal machines, etc.

These equipment can efficiently separate sediment and water, quickly remove sediment, and ensure the safety and stability of fish pond water quality. In addition, it is also necessary to take appropriate maintenance measures according to the specific situation of the fish pond, such as adjusting the feeding density and improving the breeding environment. In short, for severely silted fish ponds, it is recommended to adopt professional dredging equipment and technology, and carry out regular maintenance to ensure the normal operation of fish ponds and water quality safety.

Originally, the rice fields had been abandoned for many years, and I dug up the fish farming, and after a few years, I cleaned up the silt in the fish pond.

Before proceeding with the use and change of land use, you should first understand the relevant laws and regulations of the local government, and obtain the necessary permits and approvals. Changing the use of land or using land without obtaining the relevant permits and approvals may be considered an illegal act, resulting in legal liability and penalties. In your case, if you have carried out the act of converting rice fields to fish ponds and cleaned up the silt in the fish ponds without obtaining the relevant permits and approvals from the local **, it may be considered an illegal offence.

If the local ** is dissatisfied with this and believes that your behavior has caused damage to the environment or affected the interests of the surrounding people, you may be punished or held accountable by corresponding administrative or legal measures. Therefore, in order to avoid unnecessary legal risks and disputes, it is advisable to consult with the relevant local authorities and obtain relevant permits and approvals before proceeding with any land use or change of land use.
