Analysis on the requirements of raising snails in Paddy Field

Raising field snails in rice fields is not unfamiliar to snail farmers. This is the most frequently used method of raising field snails at present, because on the one hand, it can increase the yield of rice fields, and on the other hand, it can also raise field snails. This method of killing two birds with one stone has been adopted by many people.

Analysis on the requirements of raising snails in Paddy Field

1. Rice field requirements: Rice fields used to raise snails are required not to dry up all the year round, and pesticides cannot be used in electricity.

2. Rice field arrangement: Rice leaves a hole when transplanting, and the trench is dug within 1 week after transplanting, with a width of 20cm, a depth of 13cm and a depth of 17cm. After releasing the snail in the rice field, a fence or polyethylene screen with smaller holes is set up at the inlet and outlet of the paddy field, and the ridges around the field strictly prevent the leakage of rats and snakes, so as to prevent the snails from escaping.

3. Timely stocking: from tillering to long heading stage, that is, from late June (15 days after rice planting) to early August, 20004000 young snails weighing 4g per mu are generally released in 1 mu of paddy field. If the natural bait is rich, it can be put more appropriately, otherwise, it can be put less appropriately. If duckweed is raised in rice field, the stocking density can be increased to 8000000.

4. Proper feeding: the amount of natural feed in general rice fields decreases about 25 days after snail culture. For fields with obvious insufficient feed, land grass, vegetable leaves and melon peel can be used in the ditch to meet the snail food.

5. Timely harvest: it can be harvested in 50 days after stocking. Before fishing, drain the surface water of the field, lead the snail in the trench or trap it with bait, the catch is large and small, it can be put in once and caught many times.

6. Scientific fertilization, reasonable disease prevention and pest control: Rice fertilizer in snail field should be applied once before planting, supplemented by topdressing properly. Low-toxic and high-efficiency pesticides such as chlordimeform, Shachongshuang and Jinggangmycin are selected for disease control and pest control in paddy fields.

Prospect of field snail culture

Snail meat is a kind of nutritious natural health food, and it is also known as beauty food abroad. It contains 10.3% protein and 1.2% fat, as well as vitamins, calcium, iron and other essential elements. The nutrition of field snail meat is better than that of chickens, ducks, geese and pigs, and is no less than that of crucian carp and sea cucumbers. Snail meat can nourish kidney yin, clear eyes and clear brain, enhance muscle elasticity, delicate skin and so on.

Field snail can be used as home meat, can also be processed into a series of food, cooking a variety of medicinal meals, disease prevention and treatment. At present, the natural growth of field snail is far from being able to meet the market demand, and the field snail culture grows fast, the yield is high, and there is a wide range of ways to cultivate field snail "money".

High-yield culture techniques of field snail

First, choose the venue.

Snails have strong vitality and disease resistance, and ditches, paddy fields and shallow ponds with living water sources can be stocked. Generally, pond farming is adopted. The snail pond is generally 2 meters wide and 10 meters long, with a ridge around the pond, 0.7 meters high, and a fence net around it to prevent the snails from escaping. The bottom of the pool is covered with 20 cm thick mud, injected with new water, and the water surface is stocked with water floating lotus, small gourd, red duckweed and so on. Feed for field snails, and insert small bamboo poles or wooden strips in the pond for snail habitat and spawning.

Second, put in the seedlings.

Select snails or young snails and put them into the pool. After the pond is built, it is generally chosen to put into seedling culture from April to November. From June to September every year, a large number of field snails lay eggs, which can be picked up in rice fields and ditches, or bought in the market. the female snails are characterized by light brown color, thin shell, round body and blunt tail. The female snails of 15ml and 20g are selected and put into the pool, generally 10 female snails per square meter. Those who choose young snails as seedlings. It is released according to the ratio of male and female at 2:1. The female snail is larger, the snail body is round, and the shell is concave; the male snail is smaller, the snail body is longer, and the shell is protruding. Young snails can be caught and put on the market after about a year of breeding.

Third, feeding and management.

The snail is rich in bait, and the microorganisms, organic matter and young stems and leaves of aquatic plants are its main food. During the peak growing season of young snails, rice bran, wheat husk, bean curd, cooked sweet potatoes, small insects, small fish and shrimp and animal offal are fed every year between April and November. Can also be fed with formula feed. The feeding time is 8-9 o'clock every day, and the large bait should be chopped and fed. The daily feeding amount is about 1.5% of the snail body. Change the fresh water regularly to keep the water fresh, about once every 10 days. When the water temperature is above 30 ℃, new water should be injected frequently to deepen the water level. It is better to keep the water depth at 30 cm at ordinary times. In winter, the water level is lowered and the light is increased during the day. The water level deepens at night. Thus heat preservation, and combined with the application of some pig manure, stable fertilizer, in order to increase the temperature and improve the water quality. Snails are sensitive to pesticides and industrial sewage. We should pay attention to avoid and pay attention to the harm of ducks.

Fourth, fishing on the market.

After a year of breeding, those with a body weight of more than 15 grams can be caught and listed on the market. The fishing method can be either dry pond fishing or shallow water fishing. At the same time, attention should be paid to keeping some female snails to prepare for the cultivation of young snails next year.

Fifth, overwintering management.

When the water temperature dropped to 8 ℃, the snail began to hibernate. During hibernation, the snail drilled into the hole, leaving a small hole in the soil and bubbling from time to time. Don't eat or move at this time. The water depth should be kept at 10ml 15cm, and the water should be changed every 5 days to increase the oxygen content so that the snail can survive the winter safely.

Field snail culture cost

Because the snail culture does not need to feed a lot of bait, the cost of the bait is also very low. Therefore, basically does not need much cost, as long as you have a field in your home, then the rest is snail seedlings.

The benefit of breeding field snail is remarkable. 667m2 can produce 400kg in specializing in field snail. At present, the market price is 30.4 yuan / kg. Calculated by 3.5yuan / kg, the output value of 667m2 can reach 1400 yuan. In addition, a small amount of grass carp can be mixed in Tianluo pond to increase the benefit per unit area of snail pond. Because the snail culture does not need to feed a lot of bait, the cost of the bait is also very low. Therefore, the net profit of snail culture is about 1000 yuan / 667m2, and the benefit is considerable.

Although the method of raising snails in rice fields is very good, if the effect is good, one field can be used for multiple purposes, and a piece of land can create double or even more profits. However, raising snails in paddy fields also needs to master certain techniques and methods, and it will also double the loss if it is not handled properly.
