How to raise green lobsters in rice fields, and can you raise lobsters in rice fields? How does it w

Choose fields with good water quality, sufficient water, no pollution sources around, strong water retention capacity, convenient drainage and irrigation, and not flooded for shrimp farming in paddy fields, with an area of as little as a few acres, as many as dozens of acres or hundreds of acres. Along the inner side of the ridge of the paddy field to excavate the shrimp ditch, the ditch is 1 meter wide, 1 meter deep, the field area is larger, but also in the middle of the field to dig the field ditch, the field ditch is 1 meter wide, 0 meters deep5 meters, the area of shrimp ditch and field ditch accounts for about 20% of the total area of paddy field.

Use the excavated shrimp ditch to reinforce the ridge, level the field, and tamp each layer of soil when the ridge is reinforced, so as to prevent the ridge from collapsing during a big storm. The width of the ridge is more than 3 meters, and the height of the ridge is 1 meter. The inlet and drainage outlets should be fenced with barbed wire or fences to prevent crayfish from escaping and enemies from entering.

The water inlet channel is built on the ridge, and the drainage outlet is built at the lowest part of the shrimp ditch, according to the pattern of high irrigation and low drainage, to ensure that the irrigation can be carried out and discharged. At 1 meter away from the ridge, every 3 meters to make a meter-high pile, erected with bamboo, plant melons, beans, gourds, etc. on the edge of the ridge, wait for the vines to be on the shelf, in the hot summer to play the role of shade and heat. In the shrimp ditch and the field to transplant aquatic plants, such as bitter grass, black algae, goldfish algae and other submerged plants, aquatic weeds coverage of 30% is appropriate, and sporadic and scattered is better, which is conducive to the smooth flow of water in the shrimp ditch without blockage.

Use plastic film, cement board, asbestos tile or calcium-plastic board to build an escape wall around the field to prevent crayfish from escaping.

The lobster market has not been hot all these years. Who would have thought that alien species would have been consumed by a lot of ink before they were majestic in China. In the end, it is up to the mayor's market to be sustained by food**.

So how do you raise lobsters in rice fields? The "paddy lobster" tumor model increases farmers' income, and the "paddy lobster" breeding model that makes farmers' pockets fuller is one of the most popular and efficient ecological breeding methods in recent years, and it is also a good means for people to plant and breed economy. There are two general "paddy lobster" farming modes, one is the "planting-farming" continuous farming mode.

One is to work together, that is, on the co-working model of shrimp. Check whether the environment of the field is suitable for shrimp farming. First of all, choose the field where the lobster is grown, confirm whether it is suitable for lobster farming, and after confirming whether it can be farmed, start digging circular ditches and shrimp walls.

Many friends ask why they dig ring ditches and shrimp walls. To better farm lobsters, of course.

Rice and lobster live in different environments, so we wanted to create a more suitable environment between the two. Dig annular ditches and shrimp walls in the paddy fields: After the rice planting period, we can dig annular furrows.

It can be excavated about a meter from the ridge, and the inclination ratio of the ridge and the annular ditch is about 1:. Usually use the small word "Tian" to dig the field or use the word "well" to dig the field, mainly according to the size of the field to dig, the large one is dug with the word "well", and the small one is dug with the word "Tian".

The annular ditch of normal lobster culture is 1 meter wide and about 1 meter deep. The area of the shrimp wall is most suitable or meters. Ridge width and space utilization:

The difference between the ridges of farmed lobsters and the general ridges is that the width, height, and thickness increase significantly. Generally speaking, the ridge is more than a meter tall than the field, and the width of the top is about 2 meters, and depending on the season, plants such as parts and melons can be planted. It is necessary to do a good job in the layout of the drainage and water inlets of the ridges.

Generally speaking, diagonal cultivation in rice paddies is conducive to the smooth flow of water. The entrance and exit are usually surrounded by barbed wire about 40 50 cm high or a double wheat net of 20 purposes. Rice field disinfection and lobster seedlings:

After the field is selected for lobster farming, disinfection work begins, and the field is generally disinfected with disinfectant powder 6 months before the lobster is cast. For example, disinfecting the fields with bleaching powder, quicklime, trichlorfon, etc., and then basking in the sun for a few days to better ensure that lobsters are less affected by diseases in the later stage. Keep the water clean and plenty of feed:

After disinfecting the sea, new water is used to drain it to ensure that the water source of the field is sufficient and the water quality is clean. Rice and shrimp farming is not to throw shrimp in the water, but everything is fine, and attention should be paid to putting soybeans and animal feed in the breeding process. At the same time, lobsters are naturally more capable of climbing, so pay attention to escape management.

The water quality should be kept clean at all times during the breeding process. Otherwise, lobsters are prone to mass mortality.

You can raise lobsters in the rice field, put a lot of water in the rice field, and then put the lobster into the rice field, and put food in the rice field every once in a while.

OK. Carefully plough out the vertical and horizontal ravines, refill the water, you can insert rice seedlings, and then put lobster seedlings.

1. Paddy field condition requirements.

It is required that there is no pollution of water source, sufficient water volume, convenient drainage and irrigation of paddy fields, the altitude is below 300 meters is preferred, and the scale of water inlet and outlet application is 20 mesh bags or mesh filtration; The soil quality is better than loam, and sandy soil is not suitable for development; Water, electricity, road three links, farmland water conservancy engineering facilities, convenient drainage and irrigation. However, some farmers have transformed the rice fields that are not suitable for shrimp farming to raise shrimp, and the result often leads to more gains than losses.

2. Rice field transformation standards.

Dig shrimp ditches with a width of 2-4 meters around the field, and set up anti-escape facilities with high meters around the perimeter; Shrimp-rice symbiosis must be dominated by rice, and the area of shrimp ditch should not exceed 10% when transforming rice fields. However, in actual production, some farmers open ring ditches around the rice fields, and the width of the ditch is 3 4 meters, 5 6 meters, and even 7 8 meters, and the area of the shrimp ditch is more than 20% or even more.

3. Paddy field management.

Before planting, the field should be exposed to the sun for several days, and every 667 square meters should be splashed with quicklime water throughout the field, and after disinfection, human and animal manure should be used to prepare the base fertilizer in the field; When the paddy field is dry, the water can not be completely opened, the paddy field should generally use organic fertilizer, do not use fertilizer that is harmful to the crayfish, and drive the crayfish to the ditch dug in advance when fertilizing. Crayfish are sensitive to pesticides, so try to use biological pesticides. Sprinkle quicklime water every half month for disinfection.

The water in the rice fields should be changed frequently.

4. Selection of rice seeds.

Rice seeds should be selected with disease resistance, insect resistance, lodging resistance large spike type, rice quality is good. For rice varieties, you can choose the one with a better taste, such as Nanjing. Increase the amount of seeds, the basic amount of seedlings is about 2 kilograms;

5. Stocking of juvenile shrimp.

Before stocking, the juvenile shrimp should be soaked in 3%-5% salt water for 3-5min to kill parasites and pathogenic bacteria, and then soaked in the pool water for 1min, lifted and set aside for 2min-3min, and then soaked for 1min, so repeated 2-3 times, so that the juvenile shrimp body surface and gill cavity absorb enough water before stocking; In spring, 5,000 can be put per acre, because the profit of spring seedlings is not as large as that of shrimp seeds in autumn, so try not to put too much. In autumn, 15-25 kg per mu can be released. In the future, some species of shrimp can be supplemented according to the situation, or even not supplemented, which can be judged by the number of shrimp holes.

If there is too much, it can not be supplemented, otherwise, new seedlings should be put appropriately.

To breed crayfish in the rice field, then you should choose a sticky field with abundant water source and fertile soil to breed, first dig a trench in the rice field, and then need to disinfect with quicklime, and you need to apply base fertilizer in the rice field to supplement the fertility, and finally put the crayfish in the rice field to breed.

1. Field selection

If you want to raise crayfish in the paddy field, then we had better choose a viscous field with abundant water sources, convenient drainage and irrigation, clean water quality, fertile soil and strong water retention for breeding, the larger the area of the general rice field, the better, must not be bred in the dry field, otherwise the crayfish will not survive and grow.

2. Rice field treatment

Before breeding crayfish, it is necessary to dig a ditch on the paddy field now, generally can be excavated on the inner side of the ridge, the ditch is 1-2 meters wide, deep meters, slope ratio 1: can be, if the paddy field is relatively large, then the middle of the paddy field should also add a few ridges, pay attention to the ridge after digging.

3. Disinfection and fertilization

After the rice field is dug up, it is also necessary to use quicklime for disinfection to prevent a large number of pathogenic bacteria in the rice field from causing crayfish to get sick, and after disinfection, it is also necessary to apply base fertilizer in the rice field to make the fertility in the rice field more sufficient, and then the crayfish can grow more vigorously.

4. Carry out stocking

After the preparation of the rice field is done, you can put the crayfish into the breeding, one is to put the mature crayfish in August and September of the first year, let it reproduce and grow naturally, and you can also put the crayfish seedlings into the rice field when the water temperature rises to more than 15 in the spring.

To raise crayfish in rice fields, it is necessary to choose sticky fields with abundant water sources and fertile soil.

When selecting paddy fields, select areas with good water source irrigation conditions, relatively flat land and good soil water retention, and stay away from water bodies or regional rice fields with pollution sources to breed crayfish. In the paddy field of shrimp and rice rotation, a 2-3 meter wide breeding ditch can be excavated or not excavated, and the embankment can be broken, so as to play the role of water storage and escape.

The cultivation of aquatic plants in crayfish farming is very important, on the one hand, aquatic plants can provide a place to inhabit and shell, on the other hand, the photosynthesis of aquatic plants produces oxygen, which can improve the dissolved oxygen of the water body, in addition, aquatic plants also provide sufficient natural bait for the growth of crayfish, which greatly reduces the feed cost of aquaculture.

Advantages of raising crayfish in rice fields

The first shipment is early, **good, when breeding crayfish in the rice field, after harvesting the rice, there are many crayfish on the egg, it has come to the time to leave the mother, add water shallow and long fast, earlier than the pond shipment time, can catch up with the good**.

Second, the cost is low, no pollution, rice farming after half a year of sun sterilization, this is no cost, no pollution, unlike the pond every two or three months to be disinfected, it is really a waste of money, the effect is not very good.

The third hard soil, convenient for crayfish to make holes, crayfish like to make holes in the hard soil to build nests, rice fields are full of hard soil, very suitable for crayfish living conditions, this is the pond can not be compared.
