Rice field turtle snails turtle breeding technology with the field

Loach, snail, and green prawns have strong fertility. They can be reared in paddy fields to breed a large number of larvae for turtle feeding. They are all omnivorous animals, mainly feeding on stems and leaves, plankton, etc. Purification of water quality has no major conflict with the competition of the food. In the paddy field, the polyculture of cockroaches, snails, shrimps and turtles is a new method of breeding cockroaches by breeding cockroaches, snails and shrimps as breeding sources. It is beneficial to increase the yield of rice and put turtles weighing 100-150 grams in paddy fields, which can grow to 300-350 grams in that year. The technical points are now described as follows:

1. Well-established infrastructure Paddy fields have good conditions for water sources. They can discharge energy, flood waters, and paddy fields where there is no shortage of water, and require easy care. The construction of infrastructure is similar to the cultivation of turtles in rice fields. Paddy fields must be built around anti-escape facilities. The entrance and exit must be blocked with wire mesh or plastic mesh. The turtles should be excavated in the field to facilitate turtle activity and wintering. Tianbiangou can be used instead. 3 meters wide, 2 meters wide at the end, 1.5 meters deep ditch, the ditch length with the field may be. The ratio of the ditch area to the rice paddy area is 2:8. The central spawning sand beach is 5 meters long and 1 meter wide at the center and is 0.8 meters above the normal water surface. The turtle ditch can be planted with a water lotus, and some apricots are stocked on the field for turtles, snails, clams and shrimps. Water quality requires fertilizer, live, tender and cool, with a pH of about 7.5.

2. Selection of breeding stock turtle species to choose colorful turtles or tortoises, etc.; shrimp species, require egg-holding shrimp, strong reproduction; snails, alfalfa is best to ditch, canal, pond and other natural water collection, field snail requirements A large, round shape, thin shells of meat, dark gray shell, less thread; muddy species require dark yellow color, robust, and neat specifications. Rice varieties require lodging resistance, disease resistance, and high yields.

3. Early stocking of single-season paddy fields and rearing of larval shrimp snail species; winter free field first stocking and rearing. In general, a total of 0.7-10,000 locust species of 3-5 centimeters, 2000 snails (not suitable for stocking snails), 3,000 shrimps, and 500-800 turtles of more than 2 years old are stocked. If breeding turtles, 50-60 turtles are added and placed, and snails, clams, and shrimps continue to breed larvae, allowing the turtles to eat freely, reducing or eliminating artificial feed. Seedlings were bathed with 3% saline for 3-5 minutes before stocking.

4. Feeding management 1 fertilization water quality. Cultured snails, clams, and shrimps weigh in water quality. Before transplanting rice, 250-400 kilograms of rotting plant per acre is used as a base fertilizer. After that, according to water quality, fertilizer is applied once every 30-40 days. The transparency of water is controlled by 30 cm, and the water color is yellow-green. Water quality Water temperature has a great influence on the growth and development of turtles. Attention should be paid to observe water quality and change water in a timely manner, pay attention to controlling the water level, adjust the water temperature, keep the water depth of rice paddy 15-20 cm, and deepen properly in high temperature season. Do not use blocks under field blisters. 2 feed feeding. Using this culture method, live baits (larvae, snails, and shrimp larvae) are abundant in paddy fields, and generally it is not necessary to feed animal feed for turtles; if supplements are used, artificial feeds can be used or special feed for turtles can be used. The feeding amount is 5% of the total weight, and is appropriately adjusted according to water quality, weather, food intake, etc. In the peak season of July-September, the daily feeding volume is increased to 10%, and it strives to achieve the "four definite" feeding method. . 3 disease prevention. Grasp the principle of “comprehensive prevention, active treatment, and prevention-oriented treatment”, strengthen feeding management, regularly sterilize water bodies and reduce the occurrence of diseases; try to avoid pest control and avoid pesticide hazards. Adhere to the field of early patrols, pay attention to preventing escape, leaking, preventing poisoning and preventing snake and rodent creatures from harming.
