How can a loach be best used in a rice field?

We only need to sprinkle some dried shrimp in the rice field, because the loach eats sand rice and soil, and the rice field can also allow the loach to breathe better, so the farmed loach will also have a higher survival rate.

Plant a rice field, then put the loaches in the water and feed them some food often, so that the loaches can grow better.

To make the paddy field have enough oxygen, the water should have a certain depth, there should be some feed, the water quality should be better, and some better varieties should be selected.

If loaches are raised in the paddy fields, there is no need to fertilize the paddy fields, because the manure of the loaches is a natural nutrient and is enough for the growth of the paddy fields. There is also a nice way to cooperate in the cultivation of loaches in the rice fields, called "symbiotic relationship", where the loaches provide nutrients to the rice fields, and the microorganisms in the rice are the food of the loaches.

The paddy farming of loaches has great advantages. The use of rice paddy fields to raise loaches can save water surface and obtain food. It has the advantages of low cost and easy management. This is one of the measures for the peasants to get rich.

1. Adapt to the living environment of loaches. On the one hand, the loach is a warm-water fish, and the surface temperature of the rice fields is ideal for the growth of the loach: on the other hand, the loach prefers to inhabit the mud surface of the saprophytic soil at the bottom.

At the same time, it is also an omnivorous fish. The paddy field has a shallow water level and a fertile bottom, which is just enough to meet the requirements.

Second, without destroying the original ecosystem of paddy fields and increasing the utilization of water resources, we should realize the dual use of one water and the double harvest of one land, and directly improve economic benefits.

Third, make the ecological effect more prominent. Rice fields provide a good ecological environment for loach breeding and habitat. Loaches live in rice fields, and can directly eat all kinds of biological bait in rice fields, including earthworms, water insects, midgeid larvae, cladoperans and purple-backed duckweed, weeds in the field and some pests in rice fields, even if they are not fed, they can also obtain better economic benefits.

It plays a role in biological pest control, pesticide conservation and food contamination reduction.

Fourth, the combination of planting and breeding has been realized, and the utilization rate of cultivated land has been improved. Loach culture is a new type of breeding mode that uses paddy fields to realize the combination of planting and breeding. Rice loach aquaculture can make full use of the advantages of space, temperature, water source and bait in paddy fields, promote the symbiosis and mutual benefit of rice loach, enrich rice, increase loach, and greatly improve the comprehensive economic benefits of paddy fields.

5. Loaches have the habit of looking for benthic organisms in the sediment. Its foraging process can play a role in loosening the soil, thereby promoting the microbial activity of rice roots, accelerating the formation of rice branching roots, and strengthening the root system. Fifth, the cost reduction and efficiency improvement are obvious.

On the one hand, using paddy fields to breed loaches instead of opening fish ponds to save land and water is one of the options for protecting the environment and developing the economy. It is conducive to growth, which can reduce farmers' investment in pesticides and fertilizers in rice fields and reduce costs.

6. Loaches move up and down in the shallow water of paddy fields, which can promote convection and material exchange in the water layer, especially increase dissolved oxygen in bottom water.

7. Carbon dioxide produced by loach metabolism is an indispensable nutrient for rice photosynthesis.

Because there is the nutrients that loaches need in the rice field, and the loaches can also shuttle freely in the rice field, it is more comfortable, so the loaches will be easier to raise. Loaches are also very fond of life in the rice fields.

Because loaches can ensure the fertility of the soil and loosen the soil, it can improve the yield and quality of crops.

Because raising loaches in the rice field can make the loaches have a good living environment, the rice field can play a good role in protecting the loaches, and the rice fields have the nutrients that the loaches need, and also provide enough food for the loaches, the loaches like to live in a cool and humid place, and the rice fields also provide the loaches with the right temperature and humidity.

1. Paddy field conditions and reconstruction methods.

Loaches can be cultivated in all muddy, weakly alkaline and non-cold soaked paddy fields. The area of paddy fields selected for loach breeding should not be too large, generally about 1000m2. The ridge should be reinforced, and the mesh or plastic sheet should be buried to prevent the loach from escaping, and the inlet and outlet should be equipped with a net barrage, and a number of pits with an area of 2 3 m2 and a depth of more than 60cm should be excavated in the field.

Communicate with the pit, excavate several ditches vertically and horizontally, the width and depth of the ditch are 30 40cm, the area of the pit and the ditch accounts for about 10 of the total area of the paddy field, it is the habitat of loach when the summer high temperature, the application of pesticides and fertilizers and the rice drying field, and is convenient for concentrated fishing.

2. Stocking. The stocking time of loach seeds is suitable after the first rice planting is in the field, 3 4 days before the stocking, 40kg of rotten livestock fertilizer 100 m2 is applied in the pit and ditch to fertilize the water quality, and then 20,000 loach seeds of 3 4cm are put every 667 m2.

3. Feeding. After the loach species are stocked, feed bran bran, dry cake, earthworm, silkworm chrysalis powder, animal offal, etc., the early daily feeding amount is 5 8 of the loach weight, and then about 5, and the feed is put in the ditch and pit. At the same time, according to the water quality conditions, the fertilizer should be applied in time, and the amount of top dressing is 15kg 100 m2 each time. Rice fields should use as few pesticides as possible, choose high-efficiency and low-toxicity pesticides if necessary, and spray them on cloudy days.

At the same time, keep the water quality fresh to prevent excessive fertilization from affecting the water quality.

First, the selection of loach paddy fields: choose paddy fields with good water quality, good water retention performance, convenient drainage and irrigation, sufficient sunshine, warm ventilation and convenient transportation for loach breeding. The soil quality is clayey soil, high maturity and high fertility.

Second, heightened and reinforced ridges:

1.Time. In order to heighten and strengthen the ridges, it is generally carried out in combination with the winter farmland consolidation, and it can also be used to heighten and strengthen the ridges when the fields are ploughed up when the fields are prepared before transplanting.

2.Ridge height, width. Generally, it is required to increase the height of the ridge to 50 100 cm, and the top of the ridge to about 50 cm.

3.Tamp. After the ridge is heightened and widened, it must be compacted to prevent heavy rain from collapsing or leaking water.

4.Slope protection. If possible, you can plant some grass, melon, beans and other crops on both sides and the top of the ridge, use its root system to achieve the purpose of slope protection, if there are conditions, you can also use civil building materials such as slate, cement board and other civil building materials for slope protection, so as to ensure that the ridge is firm and firm, durable, and can effectively prevent water snakes, voles, lobsters and other holes, affect the fastness of the ridge, and is also an effective measure to prevent loaches from burrowing and escaping.

3. Excavation of fish ditches and fish slips: excavation in winter and spring agricultural seasons. The fish ditch is 80 150 cm wide and 60 90 cm deep.

Excavation perpendicular to the direction of the ditch. For smaller paddy fields, only 1 2 fish ditches need to be excavated; In large paddy fields, a fish trench is usually dug in the shape of a mouth or field around the paddy field. The fish slip varies from 5 to 6 square meters and has a depth of 60 to 90 cm.

The shape is square, round, rectangular, and other shapes. It is best to choose a location that is convenient for feeding management, such as the edge of the ridge or the inlet and outlet of the field, or the intersection of the fish ditch. It is also possible to be in the field of **.

In order to reduce the excavation area of paddy fields, ditches and ponds should be used as much as possible. The excavation area of fish ditch and fish slip generally does not exceed 5% to 7% of the area of rice fields

Fourth, excavation injection, drainage and device fish trap: the injection and drainage of the paddy field should be opened at the diagonal angle on both sides of the paddy field, and the larger area of the paddy field should be opened a few more injections and drains. All injection and drainage outlets must be equipped with fish traps to prevent loaches from escaping and predators from entering the rice fields.

The commonly used fish trap is made of Junich net, bamboo strips, branches, wicker, etc. to form a curtain, which is arc-shaped, inserted into the mud, sealed and drained, and its convex surface faces the direction of the reverse water flow, that is, the convex surface of the fish trap of the water inlet is facing the outside of the field, and the convex surface of the fish trap of the outlet is facing the field. The pore size of the fish trap is based on the fact that the loach cannot pass through.

If plastic nets and barbed wire are used as fishing fences, wooden frames should be embedded around them and buried in the mud at the injection and drainage outlets. The fish trap must be higher than the ridge, and the soil, weeds and other debris at the injection and drainage outlets should be removed frequently, so as to facilitate the smooth flow of water.

5. Flat water shortage: Flat water shortage is generally built on the ridge next to the drainage ditch, and its height is determined according to the water level of the paddy field. When the rice is transplanted, the drain is made of bricks, and two whole bricks are laid vertically.

The tiled bricks are always level with the water surface in the rice paddies, and the mouth width is about 30 cm. After the flat water shortage is done, the fish trap is installed on the outside. 9i

The most important thing in raising loaches in rice fields is to prevent escape, and to prevent loaches from escaping when the water rises. The surrounding area of the field must be heightened, and the miscellaneous insects in the field must be killed when the seedlings are planted (with crystal trichlorfon)!

1. Loaches can be raised in rice fields.

2. Transformation of paddy fields for loach farming:

The choice of rice fields. All muddy and weakly alkaline rice fields can be raised with loaches.

The area of the paddy field selected for loach breeding should be 1000 square meters, the ridge should be reinforced, the inlet and outlet should be equipped with a net fence, and a number of pits should be excavated in the field, with an area of 2 3 square meters and a depth of more than 60 centimeters. Communicate with the pit, excavate several longitudinal and horizontal ditches with width and depth of 30 40 centimeters, and the area of the pit and ditch accounts for about 10 of the total area of the paddy field.

3. One acre of land is suitable for breeding 20,000 loach seedlings of 3 4 cm.

It depends on how dense you are? Whether the survival rate is high or not, the quality of seedlings is directly related to the income.

In 1983, Ning Zhuangzhi, Anhua County, Hunan Province, used the rice field of 4 points of "late rice seedling field - late rice" to raise loaches, and in one year, 1,500 kg of loach and 350 kg of rice were harvested, equivalent to 3,750 kg of loach and 875 kg of rice per mu.

The loach has a strong ability to adapt to the environment, because the loach burrows the mud to loosen the soil and eats to remove pests, it can promote the decomposition of fertilizer, which is conducive to the growth of rice. Therefore, loach cultivation in paddy fields can not only increase the yield of commercial loach, but also promote the increase of rice yield, so as to achieve the goal of double harvest of loach and rice.

First, the selection of paddy fields for loach breeding paddy fields with weak acidity, less sediment, good water retention, and no overflow during rainfall are preferred. The paddy fields should be surrounded by high ridges, and two nets should be set up at the inlet and drainage outlets to prevent loaches from escaping. At the same time, dig some fish traps in the middle of the field or in the four corners to facilitate future fishing.

2. Transformation of paddy fields Excavate frame-type "field" shaped fish ditches and fish pits in the field. The depth of the fish ditch is 30 50 cm, the depth of the fish pit is 50 70 cm, and the area of the fish ditch and the fish pit accounts for about 20% of the field. When excavating the fish trench, the soil can be used to widen and raise the ridge, so that the ridge is 40 to 60 cm above the water surface.

3. Prepare before stocking 15 days before the loach species are stocked, 50 100 kilograms of quicklime are splashed with water per mu to kill viruses, wild trash fish, water snakes and other enemies. After 7 days, fill 20 30 cm of fresh water, and apply 200 400 kg of cow and chicken manure per mu in the sunny place, so that the loach seeds can be stocked with fertilizer water.

Fourth, put the fish fingerlings loach stocking time in April and May, the specification is 200 240 per kilogram, and the stocking amount per mu is about 20,000. The loach seeds are not fed for 7 days after stocking, and then they are fed with soybean cakes, fish meal, vegetable powder, vegetable cakes, cereal flour and other powdered materials. Live bait can be fed to earthworms, maggots, mealworms, snails, etc.

Feeding twice a day, at 8 9 a.m. and 4 5 p.m., the daily feeding amount accounts for 2% of the loach body weight. At the same time of feeding, cattle, pig and chicken manure should be applied every 10 15 days, 200 300 kg per mu, or stacked rice stalks to rot to cultivate plankton and maintain a certain fertility in water quality.

5. Strengthen water quality management at ordinary times, pay attention to replacing pool water, and change water once a week and once a week in high temperature seasons. When rice is used to control pests and diseases, it is necessary to fill the paddy field with fresh water first, and then discharge the surface water to the normal water level after using the medicine. Spraying pesticides should be sprayed directly on the rice leaves and avoid spraying into water.

It is necessary to choose pesticides that are less toxic to fish and can be digested quickly. At the same time, the pond should be inspected twice a day in the morning and evening to check whether the inlet and drainage outlets are in good condition to prevent loaches from escaping and ensure a bumper harvest of rice and fish.

6. Predators The main predators of loaches are frogs, aquatic insects, birds and ferocious carnivorous fish. Treatment:1

Remove weeds at the edge of the pond, compare the breeding environment environmentally, strictly prevent frogs from invading, find that frogs should be caught in time, and frog eggs should be removed in time; 2.The water inlet should be blocked with a sieve silk net to prevent wild trash fish from entering the pond with the water; 3.Spot birds and drive them away in time.

The standard practice is to "stock 100 kg of seed per mu". When it comes to harvesting, "500 kilograms of loaches will be harvested according to the five-fold increase in yield, and after November and during the Spring Festival, it can be sold for 15,000 yuan." If the cost is removed, it includes 4,400 yuan for 100 kg of seedlings, about 4,000 yuan for feed, 100 yuan for medicine, 300 yuan and 500 yuan for anti-escape nets (replaced once in 3 years), and about 200 yuan for ditching in the paddy field (only in the first year).

In the first year of release, the net income of loach in 1 mu of paddy field can reach 5,800 yuan. Clause.

In two or three years, the net income is expected to reach more than 6,500 yuan.
