Problems solved by technology

Judging from the existing information reports and practices, the existing overwintering test methods of artificially cultured leeches all have problems such as low overwintering survival, and have no effect on improving production.
Partially adopt the indoor water tank constant temperature wintering method, the manual labor intensity such as changing water and dredging is relatively high, and the mortality rate is relatively high. In the case of large-scale production, most of the survival rates are lower than 60%, and the cost of wintering is high, which is not conducive to production.
Existing reported methods are difficult to apply in actual large-scale production
The high overwintering mortality rate of Hirudo phenatus artificially has always been a problem in the breeding industry. It is of great significance to provide a method of overwintering suitable for large-scale artificial breeding of Hirudo philippines with simple facilities.

Embodiment 1

[0033] A method for overwintering in a greenhouse for artificially cultivating the phenanthrene, comprising the following steps:

[0034] 1) if figure 1 As shown, an earthen pit is dug on the ground 1 inside the greenhouse 7, the overwintering container 2 matching the size of the earthen pit is placed in the earthen pit, and earth 4 is laid on the bottom of the overwintering container 2 so that the earth 4 can survive the winter. The bottom of the container 2 forms a slope;

[0035] 2) Add water to the bottom of the overwintering container 2, that is, add water at the bottom of the slope to keep the soil 4 moist, and filter the healthy leeches that have no damage in appearance and no lumps in the body segments and put them on the surface of the soil 4 to make the leeches Drill freely into the dirt 4;

[0036] 3) During the overwintering period, control the temperature of the greenhouse 7 and the humidity of the soil 4, and take out the leeches after the overwintering is over...

Abstract

The invention provides a greenhouse overwintering method for artificially-bred poecilobdella manillensis lesson. The method includes steps: 1) digging a pit in a greenhouse, arranging an overwinteringcontainer matched with the pit in the pit, and laying soil at the bottom of the overwintering container to form a slope at the bottom of the overwintering container; 2) adding water to the bottom ofthe overwintering container to keep the soil wet, and releasing poecilobdella manillensis lesson to the soil surface to allow the poecilobdella manillensis lesson to freely enter the soil; 3) in an overwintering period, controlling the temperature of the greenhouse and the temperature of the soil, and taking out poecilobdella manillensis lesson after overwintering is completed. The method has advantages of easiness in operation, sharp reduction of labor, high overwintering survival rate and the like.

Description

technical field [0001] The invention belongs to the field of breeding of leeches phenanthae. More specifically, the present invention relates to a method for overwintering in greenhouses for artificially breeding B. phenantha. Background technique [0002] The Philippine leech is a species of the genus Hirudophyllidae in the class of Hirudophyllidae. It is commonly known as the Phnom Penh leech. It is mainly distributed in coastal areas such as Guangxi, Guangdong, and Hainan in southern China. The Philippine leech feeds on the blood of vertebrates such as livestock and poultry. Hirudo phenanthrene is rich in antithrombin and has a strong effect of promoting blood circulation and removing blood stasis. Currently, it is mainly used to treat cardiovascular and cerebrovascular diseases such as cerebral infarction, arteriosclerosis, high blood viscosity, high blood fat, and high cholesterol. In 2011, it was successfully included in the second volume of "Quality Standards for Zh...
