Background
Insect larvae, such as hermetia illucens (Black Soldier Fly) larvae, belonging to the family of the soldier fly, are able to feed on livestock manure and kitchen waste, thereby producing high-priced animal protein feed. And because the black soldier fly has the characteristics of rapid propagation, wide feeding habit, high conversion rate, easy management, low feeding cost, good animal palatability and the like, and the fat white larva body has the advantages of higher nutrition value and the like, the black soldier fly is widely applied to the treatment of kitchen solid residues, livestock and poultry manure and the like by various large environment-friendly enterprises and breeding enterprises since 2016.
At present, when insect larvae are cultivated, an integrated environment control scheme is generally adopted, namely insect larvae in different growth stages are uniformly placed in a cultivation workshop or a cultivation farm, the cultivation environment is controlled through equipment such as natural ventilation, a central air conditioner, a radiator, a fan, a water curtain and the like, and the environment integrated control scheme has the following problems:
1. the heat, odor and water vapor generated by the insect larvae in the growth and the cooperation process with microorganisms and evaporated materials are scattered randomly until the whole cultivation workshop/farm is filled, and at the moment, the environment control space is larger, so that the environmental control energy consumption is higher, and the cultivation cost of the insect larvae is greatly increased;
2. insect larvae take food the activity different under different temperatures, and along with the continuous activity of insect larvae in breeding the box, the insect larvae of different activities, its suitable ambient temperature, oxygen concentration, humidity etc. are also all different, and the growth of different activity insect larvae is difficult to guarantee to the scheme of environment integration control, also is unfavorable for breeding the separation of worm material in the later stage breed box.
3. In cold seasons, the raising environment needs to be heated to ensure the activity of larvae, and the integral control scheme has large heating space, so that the heating cost is increased.
4. When insect larvae are in the fast-feeding and fast-growing stage, the materials produce a large amount of heat and evaporate a large amount of water vapor into the air, and the moisture needs to be discharged through ventilation or dehumidified through a dehumidification system. In the integrated control scheme, the water vapor is emitted to the first, second and third airtight cultivation areas, the overall ventilation and dehumidification difficulty is high, and the cost is high.
5. In the later growth stage of insect larvae, the heat of the materials is gradually reduced, the temperature of the materials is also reduced, and a large amount of moisture generated in the earlier stage easily causes moisture regain of the materials to influence the subsequent screening of insects and insect manure.

Detailed Description
The invention will be further described with reference to specific embodiments, and advantages and features of the invention will become apparent from the description. These examples are merely exemplary and do not limit the scope of the invention in any way. It will be understood by those skilled in the art that various changes and substitutions of details and forms of the technical solution of the present invention may be made without departing from the spirit and scope of the present invention, but these changes and substitutions fall within the scope of the present invention.
It is well known that the growth and development rate of organisms is closely related to the environmental conditions in which they are exposed, and that different types of insect larvae can grow rapidly under their optimal cultivation conditions (e.g., temperature, humidity, oxygen demand, etc.). For example, the growth of the hermetia illucens larvae has a higher tolerance range to the environmental temperature, and the normal growth can be realized at the environmental temperature ranging from 15 ℃ to 40 ℃, so that the feeding and growth conditions can be inhibited when the environmental temperature is low, and the insect larvae can escape and even die when the environmental temperature is too high.
Therefore, according to the growth characteristics of the insect larvae, the invention designs an insect larva cultivation method and an insect larva cultivation system based on zonal environment control, which are designed based on the idea of environment zonal control, and the cultivation method and the cultivation system of the invention are described below through specific embodiments.
An embodiment of the invention discloses an insect larva breeding method based on zonal environmental control, which is shown in fig. 1, and comprises the following steps:
step 1, dividing the cultivation process of the insect larvae into a plurality of cultivation stages according to the growth and development characteristics of the insect larvae in a cultivation production period.
A dividing method for a plurality of cultivation stages in the insect larva cultivation process comprises the following steps: according to the activity of the insect larvae in the breeding feed, the activity of microorganisms in the feed and the temperature change rule of the breeding feed, the breeding process of the insect larvae is divided into a plurality of breeding stages.
In the invention, the black soldier fly larvae are cultivated as an example, and belong to cold blood animals, and the feeding activity of the larvae is not high at the initial cultivation stage when the environmental temperature and the cultivation feed temperature are low; in the middle period of cultivation, along with the continuous movement of the larvae in the cultivation feed and the growth of microorganisms in the cultivation feed, the environment temperature and the cultivation feed temperature are continuously increased, so that the feeding activity of the larvae is continuously increased and reaches a steady state, the moisture in the cultivation feed is continuously evaporated, and the moisture in the environment is increased and the humidity is increased; in the later period of cultivation, along with the reduction of nutrient substances in the cultivation feed, the activity of the larvae and the growth speed of microorganisms are slowly reduced, and at the moment, the environment temperature and the temperature of the cultivation feed are gradually reduced until the cultivation process of the larvae is completed. In this embodiment, according to the characteristics of the hermetia illucens larvae, the cultivation stage can be divided into a start-up stage, a heating stage and a cooling stage, and the characteristics of each cultivation stage are as follows:
a start period: after the hermetia illucens larvae are put into the culture feed, the temperature of the feed is approximately equal to the ambient temperature, and the activity of the hermetia illucens larvae is low, so that the first activity, the first culture temperature and the first culture ambient air humidity of the insect larvae at the stage can be defined, the temperature of the culture feed is defined as the first culture temperature, and the change rule of the first culture temperature is gradually increased.
Heating period: along with the enhancement of feeding activities of the black soldier fly larvae, the larvae grow and develop rapidly and continuously creep in the cultivation feed, the increase of the oxygen content in the cultivation feed accelerates the reproduction of aerobic microorganisms in the cultivation feed, so that the temperature of the cultivation feed is continuously increased, the insect larvae at the stage can be defined to be at the second activity, the second cultivation temperature and the second cultivation environment air humidity, the temperature of the cultivation feed is defined to be the second cultivation temperature, and the change rule of the second cultivation temperature is that the second cultivation temperature starts to fall after gradually rising.
Cooling period: along with the consumption of nutrient substances in the cultured feed, the nutrient substances which can be fed by the black soldier fly larvae and maintain the microbial activity are gradually reduced, the feed begins to cool until finally returning to the room temperature, and along with the cooling of the materials in the process, water vapor in the environment can be adsorbed into the feed again to cause the moisture regain of the materials, the adhesion condition of the insect materials can occur, and the separation of the insect materials is affected. Therefore, the insect larvae at the stage can be defined to be in third liveness, third cultivation temperature and third cultivation environment air humidity, the temperature of the cultivation feed is defined to be the third cultivation temperature, and the change rule of the third cultivation temperature is gradually reduced.
According to the characteristics of the three stages, the first activity degree is more than or equal to 0 and less than or equal to the second activity degree, the third activity degree is more than or equal to 0 and less than or equal to the second activity degree, the first culture temperature is less than or equal to the second culture temperature, the third culture temperature is less than or equal to the second culture temperature, the first culture environment air humidity is less than or equal to the second culture environment air humidity, and the third culture environment air humidity is less than or equal to the second culture environment air humidity.
It should be noted that the breeding stage of the insect larvae can be divided into 2, 4 or other numbers according to the characteristics of different insects, and the invention is not limited thereto.
And 2, setting closed culture areas corresponding to the culture stages in the culture places.
In this step, taking three cultivation stages of the hermetia illucens larva in step 1 as an example, the closed cultivation area comprises a first closed cultivation area, a second closed cultivation area and a third closed cultivation area with relatively independent physical space, the first closed cultivation area is used for cultivating the insect larva in the starting stage, the second closed cultivation area is used for cultivating the insect larva in the heating stage, and the third closed cultivation area is used for cultivating the insect larva in the cooling stage.
And 3, designing an environment control target of each closed culture area based on any one or two of the growth environment requirement and the culture process requirement of the insect larvae.
The method for designing the environment control target of the closed culture area in the step comprises the following steps:
the method comprises the steps of designing an environment temperature target and an environment humidity control target of a closed culture area based on any one or more of insect larva culture temperature requirements, insect larva culture environment air humidity requirements and insect material separation humidity requirements.
For example, when the hermetia illucens larvae are cultivated, the environmental control targets of the three closed cultivation areas designed in the step 2 are respectively:
the first airtight cultivation area: the black soldier fly larvae in the starting period are cultivated in the region, the environmental temperature in the period is basically the same as the temperature of the cultivated feed and is usually about 20 ℃, meanwhile, the activity of the larvae is relatively low when the larvae are just added with the feed, the environmental temperature in the region needs to be concerned at the moment, the environmental temperature is regulated and controlled, the region is insulated or heated to improve the environmental temperature and the feed temperature, the temperature of the region is stabilized at 25-35 ℃, and the feeding activity of the larvae is gradually improved.
The second airtight cultivation area: the black soldier fly larvae in the heating period are cultivated in the region, along with the cultivation of the larvae in the starting period, the feeding activity of the larvae is increased, meanwhile, the larvae move in the feed and the microorganisms in the feed grow, at the moment, the total environment temperature and the feed temperature of the region can be increased continuously or even exceed 60 ℃, the waste gas amount in the environment can be increased, and the moisture of the materials is evaporated by the increase of the feed temperature, so that the environment humidity and the waste gas can be increased correspondingly. In this area, if the temperature is continuously increased, the larva will escape or die due to injury, so that the environmental temperature, the environmental oxygen content, the waste gas content, etc. in this area need to be concerned, and the environmental temperature, the environmental humidity, the environmental oxygen content, etc. in this area need to be regulated and controlled, so that the environmental temperature and the feed temperature in this area are stabilized at 25-40 ℃ (optimal 35 ℃), the environmental oxygen content is greater than about 16%, the environmental humidity is less than or equal to 95%, so as to ensure that there is enough oxygen supply in this area, the environmental temperature is not too high, and the concentration of metabolic waste gas is not harmful to the larva, so as to ensure the feeding activity of the larva.
The third airtight cultivation area: along with the consumption of nutrients in the feed, the nutrients for feeding larvae and microbial activity are gradually reduced, the temperature of the feed begins to be reduced and returns to the room temperature, and along with the temperature reduction of the materials in the process, water vapor in the environment can be re-adsorbed into the feed to cause moisture regain of the materials, the adhesion condition of the materials can occur, and the separation of the materials is influenced, so that the temperature and the humidity of the area need to be regulated and controlled, and the environmental temperature and the temperature of the feed are stabilized at 20-25 ℃, and the environmental humidity is less than or equal to 80%.
And 4, regulating and controlling the environmental data of each closed culture area according to the environmental control targets of each closed culture area.
In the step, one method for regulating and controlling the environmental data of each closed culture area is as follows: environmental data of each closed culture area are collected in real time, the environmental data are compared with environmental control targets of each closed culture area, and environmental conditions of the closed culture areas are regulated and controlled according to comparison results. The real-time collection of the environmental data of each closed culture area comprises the following steps: and collecting environmental temperature data of the closed culture area outside the culture box, feed temperature data in the culture box and air humidity data of the closed culture area outside the culture box.
Taking environmental control as an example in the black soldier fly larva breeding process, the regulation and control modes of three sealed areas are illustrated:
the first airtight cultivation area: the environmental temperature data of the area is collected in real time, and compared with the target value set in the step 3, for example, when the temperature of the area is low, the area is heated.
The second airtight cultivation area: and (3) collecting data such as the ambient temperature, the feed temperature, the ambient humidity, the ambient oxygen content and the like of the area in real time, comparing the data with the target value set in the step (3), and regulating and controlling the temperature reduction, the dehumidification, the ventilation and the like of the area according to a comparison result.
And (3) a third closed culture area, wherein data such as the ambient temperature, the feed temperature, the ambient humidity, the feed humidity and the like of the area are collected in real time, compared with the target value set in the step (3), and the area is subjected to regulation and control such as heating, dehumidification and the like according to the comparison result.
