Abstract
The invention provides a new method for overwintering of blood-sucking leeches during indoor culture. The method is an indoor soilless overwintering form, and comprises the main processes of: screening an organic fertilizer with a certain thickness, humidity and particle size to serve as an overwintering bed body for the leeches in winter, filling an existing bricked cement culture pond or a special overwintering box with the organic fertilizer, determining the put weight of bloodworms according to a certain weight ratio on the basis of body sizes of the blood-sucking leeches, putting the blood-sucking leeches and the bloodworms into the bed body successively, and manually maintaining a suitable temperature and humidity to ensure that the blood-sucking leeches can overwinter safely. The new method integrates the advantages of two types of common overwintering methods namely an outdoor soil overwintering method and an indoor soilless overwintering method of the leeches, provides an unique mode of overwintering of the leeches with the assistance of the bloodworms, and has the advantages of simple and low-price material manufacturing, high unit put density of the leeches, high system integration degree, convenient and accurate control on the overwintering environment, high overwintering survival rate of the leeches, and the like.
Description
Technical field
The present invention relates to aquaculture and special animals cultivates the new method survived the winter without soil in field, specifically hirudinaria manillensis.
Background technology
Leech is the medicinal aquatic animal of special type that China is traditional, effects such as having treatment apoplexy, hypertension, the clear stasis of blood, amenorrhoea, traumatic injury of being used as medicine, and modern medicine proves leech particularly hirudinaria manillensis, has significant curative effect at aspects such as prevention and control cardiovascular and cerebrovascular diseases.
In recent years, along with human lives's pressure aggravates, cardiovascular and cerebrovascular disease is occurred frequently, and the market demand of hirudinaria manillensis rises year by year, and price also increases to 280 yuan every kilogram in 2013 from 80 in 1998 yuan every kilogram, but also usually supply falls short of demand.Due to the pollution of long-term overfishing and agricultural chemicals, chemical fertilizer, biology etc., wild leech resource reduces year by year.The source of the most domestic hirudinaria manillensis the most progressively turns to and propagates artificially.
Current leech is propagated artificially and is broadly divided into two big classes, and leech seedling is survived the winter and also had nothing in common with each other.
One class is that outdoor manually has soil cultivation, is divided into excavation ditching type cultivation and semi-artificial net cage pond culture.Manually there is soil cultivation outdoor, in autumn after leech results, typically take remaining leech kind is to arrange special region of surviving the winter on cultivation limit, pool or Tu Chi bank, allows leech specially enter natural hibernation in earth, and takes certain heat and moisture preserving measure to assist leech to survive the winter.
Another kind of is indoor soil-less breeding, and main employing masonry and cement are built into special cultivation great Chi, and part additionally uses net cage subregion in pond, to realize the subregion cultivation of all ages and classes leech.The leech kind of indoor soil-less breeding is survived the winter, water layer anhydrous or very thin in general employing culturing pool, and the intensive input of leech seedling covers the insulation material such as felt or plastic foil above.
Analyze this two classes leech Wintering Methods, outdoor breeding survive the winter owing to utilizing existing pool and irrigation canals and ditches soil bank, there is the scale of surviving the winter big, the advantage that poultry feeders workload is less, but owing to the compartmentalization difference of district's edaphic condition of surviving the winter exists, there are bury unbalanced, the seedling data of surviving the winter in the time of surviving the winter and space of leech and be difficult to inferior positions such as gathering, environment temperature and the humidity etc. of surviving the winter factor is difficult to control to, belong to the most extensive Wintering Methods.Although current indoor anhydrous cultivation achieves the synchronization of leech hibernation time, hibernation data are easy to gather, but exist owing to leech body directly contacts with cement pit, the unfavorable factors such as the fluctuation of leech hibernation temperature, humidity, oxygen content etc. is excessive, regulation difficulty.
Summary of the invention
How the technological difficulties that the invention solves the problems that is not increasing excessive cost if being that, survive the winter as main purpose with leech, and on the premise of not considering bloodworm survival rate, the hibernation for hirudinaria manillensis provides excellent environment of surviving the winter as far as possible.The parameters such as the oxygen content mainly including stable temperature, humidity and abundance.
Present invention utilizes the fertilizer through screening and preparatory processing to survive the winter bed body as leech, one has support force and the internal void of abundance through the fertilizer of dealing with earthworm, two changes that can greatly buffer ambient temperature and humidity, and sufficient oxygen exchange space is provided, meet the condition that high density leech survives the winter.
The carrier of bed body of surviving the winter both can utilize existing cement culturing pool to transform, it is also possible to utilizes the special case of surviving the winter made to carry out.The former can carry out the comprehensive utilization of culturing pool on the premise of not increasing cost, the making raw material that the latter uses is mainly based on daily seen PVC board, foamed plastics and heat insulation asbestos gauge etc., input cost is little, but compares cement pit and can realize the control of more preferable temperature and humidity.
What the present invention was crucial is a little the hibernation property difference by leech and bloodworm, it is proposed that bloodworm works in coordination with the method that leech survives the winter.
Leech especially hirudinaria manillensis, below 15 DEG C, liveness is greatly lowered, especially feed and mating behavior, when ambient temperature 10 DEG C or less, entering earth hibernation, it is the loose soil property having certain wettability that the earth of hibernation requires, and has enough gas permeabilities.
And common bloodworm, below 15 DEG C, become inactive equally, but its temperature range normally entering hibernation period is at 0 DEG C to 5 DEG C, less than 0 DEG C of death, between 5 DEG C to 10 DEG C, although bloodworm liveness becomes significantly to glide, but also it is to maintain suitable activity.In addition, between earth water content 30% to 40%, bloodworm has best liveness.
What the present invention proposed utilizes foregoing through screening the buffer medium as temperature and humidity of the fertilizer with preliminary working, and control earth temperature 5 DEG C to 10 DEG C scopes, fertilizer humidity (water content) is in 30% to 35% scope, make use of the difference of both hibernation characteristic just, define bloodworm and work in coordination with the method that hirudinaria manillensis is survived the winter.
Specifically, under said temperature and soil moisture, hirudinaria manillensis is stopped action entrance hibernation period substantially, and bloodworm does not still enter into hibernation period, although energy significantly glides, but still remains a small amount of daily routines behavior, including feed, wriggling etc..The organic matter of fertilizer is that the daily of bloodworm brings nutrition, and the activity of the bloodworm bed body that then makes to survive the winter can avoid local the driest and the hardest, remains characteristic loose, moistening, that breathe freely.
The leech survived the winter both can be the seedling in maturity period, it is also possible to be in the young leech in growth period, and both are different throwing in density, thus the input weight of bloodworm is the most different.This ratio is maintained at 30: 1 to 15: 1, and the time difference throwing in leech and bloodworm is to ensure that at 2～3 days leech has the time of abundance pierce earth deep layer and enter hibernation-like state.
This method combines leech outdoor and buries and survive the winter and the advantage of indoor two kinds of common wintering methods of surviving the winter without soil, survive the winter as main purpose with leech, on the premise of not considering bloodworm overwintering survival rate, propose and utilize bloodworm to work in coordination with the unique pattern that leech survives the winter, have material making cheap and simple, density is big, level of integrated system is high for the input of hibernation leech unit, environmental Kuznets Curves of surviving the winter is convenient accurately, leech overwintering survival rate advantages of higher.
