How to raise Ma Huang, how to breed Ma Huang

Select a pond to build a pool: choose a location with convenient drainage, shelter from the wind and the sun to build the pool, and put stones and branches at the bottom of the pool. Stocking seedlings:

Choose a robust and large horse yellow to put in the pond water. Bait feeding: Feed snails, frogs, earthworms, etc. in the pool, and you can also feed animal blood.

Post-management: ensure the cleanliness of the water quality.

1. Select a place to build a pool

Large-scale breeding of Ma Huang, to choose a convenient drainage, shelter from the wind and sun to build a pond, about 3 meters wide, 1 meter deep, the length is not limited, the bottom of the pond needs to put stones and branches, to provide a place for Ma Huang to perch, if small-scale breeding, you can choose ponds, puddles, etc.

2. Put seedlings

Choose to grow robust, large size of Ma Huang put in the pool water, each cubic meter can put about 10,000 Ma Huang, and it likes a warm environment, generally choose to put in early spring, to October, can be sold in the market.

3. Bait feeding

Ma Huang needs to provide a lot of food for it during the growth period, you can feed snails, frogs, earthworms, etc. in the pool, and you can also feed animal blood, animal blood is generally fed once a week, pay attention to the completion of feeding, to clean up the residue, so as not to be infected with diseases.

4. Post-management

When Ma Huang is breeding, it is necessary to pay attention to regulating the water quality, even if it can grow in sewage, if the density of breeding is too large, the water must be changed regularly to keep the water clean, and also to ensure that there is a certain amount of dissolved oxygen in the water, when the oxygen content is less than 2 mg per liter, Ma Huang will be uneasy.

Ma Huang is also known as leeches. Leech breeding skills: choose a place that is sheltered from the wind and the sun, and the drainage and irrigation are convenient to build a pond.

The pool is 3 meters wide and 1 meter deep, and there is no limit to the length. Leeches feed on snails, mussels, frogs, turtles, earthworms and mammals.

Captivity can use a variety of blood-mixed feed, grass meal, and even manure. When the temperature of the thermal insulation pond is above 15 in winter, leeches can feed and grow, so as to shorten the breeding cycle and achieve the purpose of year-round feeding. When the water temperature of the feeding pond is 15 30, the leeches grow well, stop feeding below 10 digging, and affect the longevity of the students above 35.

In recent years, it has been newly discovered that the preparation of rhizome has special effects in the prevention and treatment of cardiovascular and cerebrovascular diseases and anti-cancer.

It is mainly natural fishing in history, due to the abuse of pesticides and fertilizers in recent years, as well as the pollution of the environment by the "three wastes" of industry and agriculture, the wild natural resources have decreased sharply, and with the in-depth development of the medicinal value of leeches, its market demand potential is huge.

Ma Huang is a delicious aquatic product with high protein and low fat, and it is also relatively high. Therefore, horse yellow breeding has attracted more and more attention.

The first step is to buy fish fry. High-quality yellow croaker fry have the characteristics of strong vitality, no obvious symptoms, complete scales, and no obvious wounds or traces of disease visible to the naked eye on the fish body.

The second step is to prepare the farm. A reasonable breeding site must have a good water quality environment, the water temperature is stable between 20 and 30, the pH value is between, the transparency reaches more than 30cm, and the hypoxia index is below 3.

The third step is to feed reasonably. Ma Huang is an omnivorous fish, should be fed 3 4 times a week, the feeding amount is suitable for the appetite of the fish. At the beginning of breeding, they should be fed in small quantities and many times to adapt to their appetite, and the amount of feeding can also be gradually increased, and the overfeeding should be strictly controlled.

The fourth step is to eliminate the skin and clean it regularly. Regularly change the water in the breeding pond, and constantly clean up the fish manure and bait residues to ensure that the water quality is clean and excellent.

Fifth, pay attention to disease prevention. If abnormal symptoms are found in the fish during the breeding process, they should be prevented and treated in time, and drugs such as pathogen inactivators should be used reasonably.

The breeding of Ma Huang has a certain technical content, and it needs to be carefully taken care of in order to obtain better breeding results.

1. Pay attention to escape: build an anti-escape wall around the pond, with a height of more than 80 90 cm. The inside of the wall is plastered with cement and sand.

2. A large number of aquatic plants are stocked: mainly water hyacinth and duckweed. Leeches are afraid of direct sunlight, so a large number of aquatic plants can be used as fodder for snails, as well as shading, and leeches can also lay eggs on them.

3. Provide sufficient feed: about 50 kg of snails should be put into every 667 square meters of water surface. In addition, leeches should be given livestock and poultry blood clots once a week, but the blood clots should not contain salt.

In order not to affect the water quality, blood clots cannot be thrown directly into the water. A blood clot can be placed on a wooden block to float on the water. Leeches can climb up to feed after smelling, and the blood clot should not be left for more than two days.

4. Leeches should not be directly put into the pond after introduction: because the leeches themselves will produce a layer of mucosa as a protective film during transportation. Choose a cool, damp area around the pond and place the leeches in it and let them climb into the pond on their own to reduce death.

5. Pay attention to observation: leeches breed in the soil under the cover, not in the water. During the breeding period, if the water overflows the soil bed for about 7 days, the leech eggs will die due to lack of oxygen, so attention should be paid to ensure the success of breeding.

6. Timely capture: The capture period is generally in October. The salvaged leeches are divided into large, medium and small.

The large ones are screened out and put back into the pond to be kept as leech seeds; The small ones are also placed in a pond to continue to be raised, so that they can be salvaged when they are raised to more than 15 grams in the second year**; Medium ones should be processed into dry products immediately after processing**.
