Detailed Explanation of the Forcing Cultivation Techniques for Softening-Type Chicory
After the roots are harvested, it is best to subject them to a period of low-temperature treatment before carrying out forcing cultivation. The duration of the low-temperature treatment varies by variety; early-maturing varieties can be treated for a shorter time, while late-maturing varieties should be treated for a longer time, so that tighter chicons can be formed. The methods of forcing cultivation are quite flexible and can be broadly divided into the soil culture method and the water culture method. The soil culture method is a relatively traditional cultivation method and can be carried out by digging trenches in the ground inside plastic tunnels or greenhouses. Its characteristics are low cost and simple operation, but the fact that the chicons formed are not clean is its greatest drawback. The water culture method requires specialized

Detailed Explanation of Key Technical Points for Disease Prevention and Control in Soft-Shelled Turtles
In zoological classification, the soft-shelled turtle belongs to the phylum Vertebrata, class Reptilia, order Testudines, family Trionychidae, genus Pelodiscus. It has strong adaptability to the external environment and great vitality, and is distributed across temperate and subtropical regions worldwide, as well as commonly found throughout China. The soft-shelled turtle is an amphibian that breathes with its lungs, mainly living in water, occasionally coming ashore to rest, or swimming to the water's surface with its head extended above the water to breathe. The ecological habits of the soft-shelled turtle are characterized by three likes and three fears. First, it likes quiet and fears disturbance; second, it likes sunlight and fears wind; third, it likes cleanliness and fears dirt. The soft-shelled turtle is naturally timid,

What practical cold-proof measures are there for fish and soft-shelled turtle farming
1. Pond selection Choose a deep-water (over 2 m) pond sheltered from the wind and facing the sun for natural overwintering. The water in the overwintering pond should not remain stagnant for long periods; usually replace part of the pond water every 20 to 30 days, each time replacing 1/4 to 1/5 of the total pond water, to prevent pond water contamination. 2. Set up windbreak walls and cold-shelter holes On the north side of the pond, a 2 m high windbreak barrier can be built with straw or earth, and on the east and west sides build earthen walls sloping toward the south, forming a winnowing-basket shape, to reduce attacks by the north wind, so that when a cold wave strikes the water temperature will not drop noticeably. Around the pond, drainage

Construction Methods and Technical Points for Soft-Shelled Turtle Ponds
1. Hatchling turtle pond: Those from just hatched to under 10 grams are called hatchlings. The pond area is 2 sq m to 8 sq m, rectangular, with a depth of 0.3 m to 0.4 m. The water depth is maintained at 0.1 m to 0.15 m, the pond bottom is covered with fine sand, and a shade shed 1 to 1.5 m above the top of the pond is built over it. Resting platforms about 20 cm wide need to be built at both ends. At the junction of the resting platform and the water surface, build a 30° slope so they can climb up and down. 2. Juvenile turtle pond: Those weighing about 10 grams to 100 grams are called juveniles. The pond area is 20 sq m to

Methods for determining drug dosage in soft-shelled turtle (Pelodiscus sinensis) farming
1. Determination of dosage for external-use drugs (1) Determine the drug concentration to be used (ppm) based on the safe concentration of a certain drug for soft-shelled turtles and the lethal concentration of the drug against pathogens. (2) Accurately measure the volume of the turtle pond or determine the volume of water for immersion bathing. Calculation method for water volume: water volume (m^3) = area (m^2) x average water depth (m). (3) Calculate the drug dosage: dosage (g) = concentration of the drug to be used (ppm, i.e., g/m^3) x water volume (m^3). 2. Internal
