What are the characteristics of outdoor leech rice farming?

Leech, also known as leech, has been a precious medicinal material since ancient times, and it can be used for angina pectoris and brain.

Stroke, bruises, etc. At present, the resources of wild leeches are becoming less and less, and Japan has to take it from our country every year.

Imports of thousands of tons of leeches have led to a rising number of leeches. Leech farming is low cost and quick effect. Here is a brief introduction.

Ecological breeding technology of leech paddy field, for reference.

1. Paddy field conditions require sufficient water sources, convenient drainage and irrigation, good water quality, good water retention, and surface.

A total area of 667 1334 square meters is appropriate.

2 Main facilities ditch. Dig a trench around the field, 1 2 meters deep and 2 0 meters wide, another.

A number of tunnels with a depth of 0 4 0 5 meters and a width of 0 6 0 8 meters are excavated in the field to communicate with the ditch to form a "well" and "abundant" shape. The ditch area accounts for about 25 of the total area of the field. Dike. The embankment is 1 m wide and 0 6 m high. Escape walls and inlet and drain outlets. The field is surrounded by plastic film with a height of 0 3 meters.

wall, inlet and drain are equipped with nylon nets to prevent leeches from escaping.

3. Rice transplanting Select rice products with long growth period, hard stems, resistance to diseases and insects, and strong tillering.

Planting. 4 Leech seed stocking Leech seed stocking 10 days before leech seed stocking apply 300 kg per 667 square meters.

Decomposed organic fertilizer, and at the same time put aquatic plants such as black algae and water peanuts to cultivate microorganisms and aquatic weeds, so as to ensure that the leech seeds can be eaten as soon as they are stocked. Leech seeds can be purchased from the farm, or they can be purchased.

In spring and summer, pigs' blood-soaked grass is used to trap them from natural waters, stocked at 800 1 per square meter of water surface

000 tails. 5 Usual management of bait. Leeches are omnivorous and animal-eating, and their staple food is microorganisms in water

Floating algae, love to eat snail meat, pork liver minced, hobby to suck animal blood. Artificial breeding can be mixed with livestock and poultry blood.

Ingredients or grass powder, etc., meat and vegetables are matched. Mussels or snails can also be put into the ditch to allow them to reproduce naturally.

Leech feeding. Feeding should pay attention to the "four determinations". "Timed", once a day in the morning and once in the afternoon; "Positioning", Tanaka's shallow water's edge; "Qualitative", fresh bait, timely removal of residual bait; "Quantitative", according to the water temperature, etc.

Adjust the amount of feed until you are full. Fertilize. The paddy field was fully applied with organic fertilizer at one time, and 667 square meters were applied.

3000 kg. When the fertility decreases, rapeseed cake powder can be applied, and 10 kg can be applied to 667 square meters, which is supplemented.

The leech bait is also used as top dressing, a small amount and many times. Medication. Due to the fact that leeches are extremely resistant to disease, coupled with rice fields.

Therefore, rice and leeches rarely suffer from diseases. Medication is usually not necessary. Water quality. Peacetime.

The water layer is maintained at about 20 cm, and new water is filled every 5 7 days. Escape prevention. Patrol the pond every day, find that there are problems with the embankment, escape wall, and inlet and drainage facilities, and repair them in time.

6 Processing and sales Leeches can reach commercial specifications after half a year of raising, and they can be harvested after rice.

Capture processing, catch the big and keep the small. Put the caught leeches into a container with 5 10 salt water, let them all die, then rinse them with clean water, spread them on a bamboo curtain or mat to dry**. Excellent.

The standard of dried leeches is: neat specifications, no impurities, and a moisture content of less than 20%.

It doesn't make the slightest sense! The water level requirement for leech culture is 40 to 80 centimeters, and most of the water level requirements for the growing season are above 60 centimeters. The place where you can grow rice is not suitable for leeches, and the place where you can grow leeches is not suitable for rice, and if you change the pond to look like what the upstairs said, the area where leeches and rice grow at the same time will shrink, and of course the yield will also shrink.

In addition, it is impossible to have a harvest without several toxic pesticides in the growing season! You can't breed leeches with medicated leeches! Another is that there are many small thorns on the leaves of rice, and leeches will climb up to aquatic plants and ponds when it is hot and the water lacks oxygen, which will also hurt leeches.

The above points are my experience summarized in breeding, so there is no point in saying it. FYI. Anhui Friendship Leech Farm.

Rice farmingLeechesIt is an ecological breeding method.

Rice field breeding leeches need to be transformed to the rice field, digging ditches around the area and **, and dividing it. Fertilize properly, and plant some aquatic plants, which will provide bait for leeches. Leeches can be put into the rice field, 800-1000 can be put per square meter, fed twice a day, snail mussel meat can be fed, and a certain amount of animal blood can be put every week.

Leech farming precautions

Leech (Locust.

They prefer to survive in rocky water, with a firm bottom and shore of the pond, which gathers on shallow aquatic plants in the coastal zone or in moist soil or grass on the shore, which provide them with a sessile entity and a place for defense.

Harmful substances in the air will not have a direct impact on the water quality of the pond, but they will also have indirect effects, such as the toxic substances in the toxic air dissolved in the water through the air flow, although they will not cause the death of leeches, but will affect the quality of leeches. Some also have a direct impact on the water quality, such as sulfur dioxide.

Dissolving into water lowers the pH of the water.

Causing effects on leeches.

Leeches, also known as leeches, are a valuable Chinese medicinal material

That's a lot to say, there is money to invest, there are people to manage, there are skills. That's it! Don't do anything else...

AbstractWhen stocking leeches, the water depth of the cement pond should be controlled at about 25cm. Before stocking leech seedlings, some damaged, malformed, hybrid, and sick leech seedlings should be eliminated. The body length of the leech is about 2cm, and 70 -100 leech seedlings can be put per square meter.

Because cement pond culture is not suitable for leeches to reproduce naturally, so do not need to put leeches, basically based on young leeches, it is best to choose more than two months of healthy leeches as seedlings, the larger and more robust the individual of the young leeches, the higher their survival rate, the faster the growth, the larger the individual of the commercial leeche, and the more popular with the market.

Can snails reproduce on concrete floors, what do they eat, viviparous, eggs are fertilized and developed in the mother's nursery, and they are excreted only after they grow into larvae. Snails generally have only 3-7 embryos per litter. Snails reproduce throughout the year in spring, summer, autumn and winter.

The snail eats microorganisms in the water, the relatively young stems and leaves of aquatic plants, and organic detritus, which is omnivorous.

Thank you for your question.

No need to reply anymore, thanks.

1. The pond water is drained and exposed to the sun (using 20 kg of quicklime to throw the whole pond, and then ploughing. This is effective in killing bacteria at the bottom of the pool).

2. After entering 20-30 cm of water, use 40 kg of chlorine dioxide for disinfection at the bottom of the pool, and after 4-5 days, use [detoxification leech Shuang (1 mu bottle)] + sodium thiosulfate 1 kg mu] for water detoxification The next day sprinkled grass seeds, and then use [leech water fertilizer (2 mu bottle)] for fertilizer water, so that the operation is not easy to moss, and the aquatic plants are vigorous.

Note: If fertilizer and water are difficult, cooperate with [Leech Stimulation Stop (2 mu bottle)] + detoxification Leech An (mu bottle)] to supplement the trace elements of the water body and quickly fertilize.

Note: Vibrio vermiculi for disinfection of cocoon production pond (2 acres bottle).
