The technique of how to cultivate field snail

Farmers can obtain considerable economic benefits by using small water surface or paddy fields to cultivate field snails. The techniques of field snail culture are introduced as follows:

First, the field snail culture site selection field snail culture site should choose the place with sufficient water source, good water quality, humus soil and convenient transportation. There better be running water.

The construction of culture ponds. The specification of the snail pool is generally 1.5 li 1.6 m wide and 10 mi 15 m long, and the topography can also prevail. There is a ridge around the pool, which is about 50 centimeters high. There are water inlet and outlet at both ends of the pool, and a block is installed to prevent the snail from escaping. At the same time, the sparse planting of Zizania caduciflora and other aquatic plants in the middle of the culture pond can not only increase the land yield, but also create a good ecological environment for the growth of snails.

2. Stocking quantity and feeding management

The main results are as follows: 1. The stocking density of field snails is generally 100 per square meter. At the same time, about 5 silver carp and bighead carp fingerlings in summer flowers are cultured in the main body. The stocking time of field snails is usually in March.

2. Fertilizing and baiting. The aquaculture pond first applies some feces to cultivate plankton to provide bait for field snails. The amount of fertilizer application depends on the fat and thin of the bottom material of the snail pond. After the snail is put into the pond, it is fed to green vegetables, rice bran, fish offal or vegetable cake, bean cake and so on. Green horn, fish offal should be chopped and rice bran and other feed mix well. Vegetable cakes and bean cakes should be soaked and softened to facilitate snail feeding. The amount of feeding depends on the feeding situation of field snails, which is generally calculated according to 1% of the total amount of field snails, which is fed once every 3 days. Feeding time every morning, the position of feeding does not have to be fixed, feed is put in every other day. When the temperature is lower than 15 ℃ or higher than 30 ℃, no baiting is needed.

3. Water quality regulation. First, the snail pond should often inject new water to regulate the water quality, especially in the breeding season, it is best to keep the pond water flow, especially in the high temperature season, the effect of running water culture is better. It is better to breed in micro-running water in spring and autumn. The water depth of the snail pond should always be kept at about 30 cm. The second is to adjust the acidity and alkalinity of water. When the PH value of the pool water is on the low side, 0.15 Mel 0.18 kg of quicklime is applied per square meter and sprinkled every 10 mi 15 days, so that the PH value of the pond water is kept at 7 Mel 8.

4. Overwintering management of field snail. When the water temperature dropped to 8 ℃, the snail began to hibernate. During hibernation, the snail drilled the soil with the top of the shell, leaving only a small round hole in the soil surface, and bubbles appeared from time to time to breathe. Field snails do not eat during the overwintering period, but the culture pond still needs to maintain a water depth of 10 Mel 15 cm. Generally, water is exchanged every 4 days to maintain a proper oxygen content.
