Is rice fish farming reliable? What kind of fish can you keep in a rice field?

Reliable, fish farming in rice fields can make money. Rice and fish farming is actually using the water in the rice field to raise fish, from which the fish can be used to eat the pests and weeds in the rice field.

Defecation and fertilization make rice grow better, and fish products can also be obtained, which is also one of the methods of fish farming in rural areas. There are a variety of fish stocked in the rice fields, and most fish farmers in the rice fields will stock crucian carp, carp, grass carp, loach, and silver carp.

Wait, usually the water in the rice field is relatively shallow, and the types of mixed culture should not be too much, and it should be properly matched, and the amount of fish stocking should be determined according to the rice field. In the process of rice planting, increase the spacing between rice plants, can strengthen the ventilation of the rice field, can also make room for more activities for the fish, rice not only will not reduce the yield, but also do not need to fertilize, spray pesticides to remove insects, save time and effort, if the management is good, one acre of field.

100 catties of fish and 1,000 catties of grain are sold for more than 10,000 yuan.

Rice and fish farming is certainly reliable, as there have been many examples of this before. China's traditional agriculture to apply organic fertilizer, such as human and animal manure, rice stalks, green manure, etc., when organic fertilizer applied to human paddy fields, there will be a lot of microorganisms and plankton breeding, which are good material for fish. The fish raised in the rice fields feed on plankton and weeds in the fields, and the fish not only do not compete with the rice for fertilizer, but also provide the rice with organic fertilizers such as manure and food residues.

Reliable. There is a kind of fish called Hehua fish, which is raised in rice fields. Hehua fish is a kind of carp species with a dark and translucent body color, that is, black carp.

Hehua fish takes fish fry and breeds them in rice fields, because they grow up after eating the grass flowers that fall into the water, and the fish meat has the fragrance of grass flowers.

Hehua fish has miscellaneous food, fast growth, strong reproductive ability, generally weighs 50-250 grams, has fewer spines and more meat, delicate meat, soft bones without fishy smell, and high nutritional content.

Of course, fish farming in rice fields is very reliable, there is sufficient water in the rice fields, and there are many nutrients in the rice fields, and fish can also absorb these nutrients. This is a very good way to breed.

It is still feasible to raise fish in rice fields, after all, there are a lot of organic matter in rice field fish farming, which can meet the bait of fish, and fish feces can also be used as rice fields. Fertilizer is arguably the best of both worlds.

First of all, it is safe to say that "fish can be raised in rice fields"! In fact, it is not uncommon to raise fish in rice fields, this way can make greater use of the space of rice fields, achieve a win-win situation between fish and rice, and is a new model of planting and breeding industry! However, in the actual operation process, there are "three contradictions" that need to be solved, and this is also the key to the success or failure of rice and fish farming!

Contradiction. First, the contradiction between fish farming and drying land!

As we all know, for paddy fields, after rice seedlings are planted, the water in the paddy field should be emptied and the land should be sunburned! However, for fish, water is inseparable all the time, and this has become a pair of contradictions! How to solve it?

Under normal circumstances, everyone uses the way of digging fish pits or ditches in rice fields, and the width and depth of a ditch are about 50 60cm, which are staggered vertically and horizontally in the rice field to form a "tic-tac-toe" or "field"! For the fish pit, each square is roughly 2 meters * 2 meters * 1 meter, and it is connected from end to end! When the water is drained, the fish can have time to dodge and achieve a win-win situation in the fish and rice industry!

Contradiction. Second, the contradiction between fertilization and fish farming!

For fish, the requirements for water quality are very high, so it is unlikely that chemical fertilizers will be used for fertilization in rice fields! So, how do you strike a balance between the two? In the author's opinion, replace chemical fertilizers with organic fertilizers!

If the fertilization is farmyard fertilizer, the amount of fertilizer should generally be controlled, and the farmhouse fertilizer must be fully rotted!

Contradiction. 3. The contradiction between rice field disease control and fish farming!

Of course, for rice and fish farming, the degree of harm caused by pests and diseases in general rice fields is much lower than that of just rice field cultivation! In general, the use of pesticides for disease prevention and control in the process of rice and fish farming is not considered! However, if the disease in the paddy field is serious and it is really necessary to use drugs for prevention and control, it is generally necessary to choose and control the dosage of drugs, and it is necessary to use agents that are less harmful to fish for spraying!

And it is required that the water level of the rice field should reach more than 20 cm, and it is generally necessary to spray it for breakfast!

Fish farming in rice fields is a more reliable thing, because the ecological environment in the rice fields is relatively good, and fish can also provide corresponding nutrients for the rice fields.

I think that fish farming in rice fields is still more reliable, because rice fields need nutrients, fish feces and water quality in the pond are nutrients absorbed by rice grains, and rice is the carbon dioxide and oxygen released, which are also needed by the fish in the pond to complement each other's needs, so that the rice fields grow more vigorously and the fish are fatter.

Fish farming in rice fields is unreliable, and rice fields need to be fertilized and insecticidal, which has a great impact on fish.

In some respects, the benefits of rice fish and shrimp farming are particularly many for rice farmers, but rice fish and shrimp farming also has a fatal flaw, if farmers ignore it, it can easily lead to the reduction or even extinction of sick rice production at home. This defect is that pesticides cannot be used. In recent years, the slogan of ecological agriculture and organic agriculture has been shouted very loudly, and some people have called on farmers not to use pesticides to reduce pesticide residues in various crops and fruits and protect everyone's health.

As we all know, in recent years, the cost of farming has been very high, and if pesticides are not used, the crop yield will be reduced on a large scale, and the grain harvested by the peasants may not even be able to return to its original cost at that time.

Then again, the use of pesticides is indispensable in rice fields, but when there are fish and shrimp in the field, the spraying is very restricted, and many pesticides can not be played, because a dozen, but where there are pesticides falling on the water, all pesticides are basically toxic, some are very toxic, and it is difficult for fish and shrimp to survive if they are eaten.

It can be said that there are advantages and disadvantages to raising fish and shrimp in rice fields, and farmers should decide whether to breed fish and shrimp according to their own needs.

Rice paddy fish farming is reliable because there are many pests or other plankton in the rice paddy fields, as well as duckweed, which are particularly suitable for raising omnivorous fish such as carp. In this way, the fish manure can fertilize the fields and then eliminate some pests.

Rice and fish farming are reliable. On the one hand, it can provide nutrients for the growth and development of rice fields, on the other hand, fish will also have feed to eat, which can save the cost of feeding, which can be described as the best of both worlds, but there must be a scientific and reasonable breeding method, so as to achieve the effect of booking and be profitable.

China's traditional agricultural fertilizer to apply organic fertilizer, such as human and animal manure, rice stalks, green manure, etc., when organic fertilizer applied to human paddy field, there will be a lot of microorganisms and plankton breeding, which are good fish material. The fish raised in the rice fields feed on plankton and weeds in the fields, and the fish not only do not compete with the rice for fertilizer, but also provide the rice with organic fertilizers such as manure and food residues. It's like building your own ecosystem.

As a result, rice raises fish, fish raises rice, and the rice field becomes a "fish and rice field". Rice field fish farming, pests living in the water or falling into the water can be preyed on by fish, thereby reducing the degree of rice damage, reducing chemical pesticides, and alleviating the pollution of farmland environment. Therefore, as a measure of biological control, rice and fish farming can play a role in improving the farmland environment and maintaining ecological balance.

Rice field fish farming is more reliable, and it has been proposed, but in the actual breeding process, there will be many problems, which will eventually lead to the reduction of rice field yield, the slow growth rate of fish fry, and not meet good expectations, so the method of rice field fish farming is not widely accepted, and it takes time to precipitate.

Rice and fish farming is very reliable. That's killing two birds with one stone. Some pests in rice paddies can be removed. Fish droppings. It will raise the nutrition of the rice field by itself, so it will kill two birds with one stone. Measure.

Reliable, that is, if you raise fish, the rice field can not be fertilized and sprayed, green planting, green breeding, the yield should be lower than the general rice field, but the highest high, green ecological rice, is also very popular now, fish is also favored by a lot, and now they are not willing to eat food with more pesticide residues, which just meets people's requirements!

Yes, there will be no problem with raising fish in the rice field, as long as the fish are adaptable, they can survive in a relatively poor environment to the end, and the environment itself is still relatively harmonious for the fish, and there will be no problems in surviving in it.

Rice and fish farming is still very reliable, and this kind of ecological environment can convert the maximum components of nutrients and substances into energy.

In the past, fish farming in paddy fields only raised a small number of species such as carp, crucian carp and grass carp, but now it has developed to stocking tilapia, silver carp, bighead carp, bream, catfish, river crab, loach, giant river prawn, green shrimp and other varieties, and can also develop the production of pingping, bamboo shoots, vegetables, edible fungi and other production for comprehensive aquaculture.

Stocked breeds can be selected according to different conditions in different regions.

In principle, all species suitable for pond culture can be cultured in rice paddy fields, but rice paddy fields are generally dominated by carp, and some crucian carp, tilapia, etc. can also be raised.

Carp can grow well in shallow water, omnivorous, can eat weed seeds, young roots, shoots, small underground stems, as well as some filamentous algae and various insects, mollusks, earthworms, zooplankton, etc.

The fish suitable for raising in the rice fields are: grass carp, carp, crucian carp, and tilapia.

Hehua carp, carp are generally raised in rice fields, crucian carp can be, too big is not good.

In the rice fields, grass carp can be raised, and loaches can be raised.

The cost of breeding these aquatic products in the rice field is low and the benefits are high: 1, the rice field fish farming rice field fish farming is mainly rice, taking into account the fish farming, not only can obtain fish products, but also can use the fish to eat the pests and weeds in the rice field, at the same time the fish excretion manure and turning the soil to promote the decomposition of fertilizer to create good conditions for the growth of rice, to achieve the purpose of increasing the yield of rice and fish, generally can increase the yield of rice by about one percent, the fish can be cultured to grass carp, carp, etc. 2. Rice field shrimp farming in the paddy field around the excavation of the ring ditch and the use of the shallow water environment of the rice field, both planting rice and breeding crayfish, rice in late April to early May under the planting of seedlings, in the end of May to early June began to plant seedlings, the use of shallow water, wide rows, dense plant planting methods, and appropriately increase the planting density on both sides of the ring ditch on the inner side of the ridge to play the marginal advantage.

The stocking size of crayfish is 200 300 kilograms, the density is 3000400 acres, and the time is in April and May. 3. Rice loach farming is a relatively simple way of raising loach in rice field, but it is necessary to heighten and strengthen the ridge, do a good job of anti-escape facilities at the inlet and drainage, dig a "well" shaped ditch in the field, 30 40 cm wide, 50 cm deep, 1000 2000 loach seedlings per mu, use livestock manure and compost as base fertilizer, feed soybean cakes, vegetable cakes, rice bran, etc. every day, field management according to ordinary rice field management, each mu can produce loach in more than 50 kg. Farmers breed these kinds of aquatic products in the rice fields, with low cost and high efficiency!

4. Rice field crab farming is a kind of rice and crab symbiosis planting and breeding mode, rice planting adopts large ridge double row, side row encryption, soil testing and fertilization, biological pest control and other technical methods, so that the crab rice field has sufficient sunlight and reduces diseases, which not only ensures rice yield, but also produces high-quality rice. River crab breeding adopts early temporary breeding, early feeding and early entry into the field, which can not only remove weeds in the paddy field and prevent rice insect pests, but also improve soil fertility with manure. 5. Rice field frog farming is a kind of rice frog symbiosis planting and breeding mode, which can not only control the harm of rice field pests, reduce the amount of pesticides, but also maintain the natural state of frog survival, which is conducive to the growth and development of frogs and saves the cost of raising.

At the same time, the increase in the income of frog farming in paddy fields is obvious, and the utilization rate of rice planting in paddy fields with free-range frogs is about 80%, although the total rice yield is reduced by about 20% due to the reduction of effective planting area, but the economic benefits are greatly increased. 6. The breeding mode of eel in paddy field is to use the paddy field with better water retention performance as a breeding base after a little transformation, and the transformation of the paddy field is mainly to dig one or several small eel ditches in the paddy field, and lay an anti-escape net on the paddy ridge. There are many advantages of eel farming in paddy fields, which do not affect the cultivation, management and harvesting of rice, and can also take advantage of the good shallow water conditions and shady environment in rice fields to carry out semi-artificial and semi-wild breeding of yellow eel, so as to improve the yield of farmland.

100 kg of fish fry are put into one acre of rice field fish farming. When the water depth is about 30cm, a single fry weighing 75-100g can be stocked with 450-500 fish per hectare of paddy field. When the water depth is 35-50cm, a single fry weighing 100-150g can be stocked with 500-600 fish per hectare of paddy field.

Fish farming in paddy fields can promote rice production. Rice and fish farming allows for the reuse of resources without the need for additional arable land. The development of fish farming in paddy fields will not only not affect rice yield, but can also promote and bury rice to increase production.

Fish farming in rice fields can increase farmers' incomes. Fish farming in paddy fields can not only increase grain but also increase fish, and can make paddy fields less chemical fertilizer and less pesticide spraying.

Design method of fish farming in rice field

1. The fish species that are more suitable for raising in rice fields are herbivorous and omnivorous fish, such as grass carp, carp, crucian carp, tilapia, etc. Bighead carp can also be stocked, but bream cannot be stocked. If fish are raised in double-cropping paddy fields, the stocking specifications per mu are:

There are 300 carp, 100 crucian carp, 100 grass carp, and 50 bighead carp, and about 75 kilograms of wild ants can be harvested per mu with appropriate bait.

2. Fish fertilization in paddy fields is mainly based on farmhouse fertilizer and basal ridge fertilizer. When using fertilizer, it is necessary to grasp the safe concentration, and the fertilizer can not be sprinkled directly into the fish ditch, and it can also be applied in rotation in half a field.

3. Before applying pesticides, the fish ditch must be dredged and the water level deepened.
