Description

Green breeding technology of black soldier flies based on solid waste treatment

technical field

The invention relates to a breeding process, in particular to a process for cultivating black soldier flies. During the growth process of black soldier flies, the larvae of the black soldier flies are responsible for solid waste (such as kitchen waste, animal manure, agricultural and forestry waste, etc.) It realizes green and pollution-free waste treatment, and at the same time, the mature larvae are the source of high-quality protein feed, which completely realizes the green and environmental protection industry chain, and belongs to the field of agricultural breeding technology.

Background technique

Black soldier flies (scientific name: Bright spot flat-horned soldier flies) is one of the common types of soldier flies in my country. Black soldier flies are saprophytic insects and eat a wide range of food (feces, kitchen waste, rotting organic matter, fruit and vegetable waste, etc.), The entire life cycle includes four stages: egg stage, larval stage, pupa stage, and adult stage, about 30-40 days. The growth period of larvae treated by cooking is only 5-7 days, but the larvae are rich in nutrients and widely used. Related products It is suitable for commercial development and promotion and sales; at the same time, the biological characteristics of black soldier fly larvae are outstanding, not only can they eat fresh kitchen waste, but also have a wide recipe, large feeding amount, moderate development cycle, easy to raise, larvae Comprehensive nutritional value, high ecological safety, strong stress resistance, insensitivity to oil and salt, etc., make it the most promising biological species in the field of kitchen waste disposal.

Nowadays, the artificial breeding of black soldier flies is a technology and application that has just emerged in China in recent years. It mainly uses the scavenging and biological characteristics of black soldier flies to treat organic solid waste, so as to realize the treatment of kitchen waste or livestock and poultry manure. At the same time, the feces discharged by the black soldier fly can be used as organic fertilizer when eating kitchen waste, and the black soldier fly larva itself is a valuable high-protein raw material. It is more than 45%, the fat content is about 20%, and it is also rich in various vitamins and trace elements required by various animals, which is very suitable for raising animals. According to scientific determination, the black soldier fly larvae have a balanced and comprehensive nutrition, and the animals have good palatability. , especially suitable for raising aquatic animals. Therefore, the use of the breeding process of black soldier flies can not only realize the treatment of kitchen waste, but also the black soldier fly feces produced in the treatment process can be used as an excellent organic fertilizer, and the finally grown black soldier fly larvae can also be used as excellent organic fertilizers. It realizes the pollution-free treatment of kitchen waste and the recycling of resources, which is another major innovation in modern agriculture.

However, in practical applications, it is found that the current black soldier fly culture is in a free-range state, lacking scientific and effective breeding techniques, and conventional breeding only simply puts the black soldier fly larvae into the breeding box for cultivation, such as Chinese invention patent CN201711440173. 5 discloses a kind of "black soldier fly breeding basin and black soldier fly breeding device"; its essence is just a breeding box with simple functions, lacking regulation such as feeding, breeding environment control, and receiving materials, so based on the above-mentioned device. The conventional breeding process has low breeding efficiency and poor effect, and a new breeding process is urgently needed to replace the above-mentioned process.

SUMMARY OF THE INVENTION

The purpose of the present invention is to overcome the above-mentioned deficiencies, and provide a black soldier fly green breeding process based on solid waste treatment, which can form a large-scale breeding method of flow, thereby improving output and garbage disposal capacity.

Step 3, collecting insect material: continue to carry out step 2 until the black soldier fly larvae are mature, and then use a material extractor to collect the mature larvae insect material by vacuum adsorption;

Step 4, material separation: separate a small part of the worm material and enter step 5 to cultivate and lay eggs; the remaining worm material is separated from the worm body and the residue by a screening machine, and the finished worm body after separation is shipped;

Step 5. Cultivate and lay eggs: place the ovipositor on the top of the inducer, and the ovipositor has a dark layer for adults to climb into. After the mature larvae in step 4 break through the pupae and fly out, they will be lured by the inducer. Climb into the dark layer to spawn;

Step 6. Incubation: after shoveling the eggs laid by the adult worms in step 5 onto the hatching bed, place the hatching bed in the worm breeding box, and lay the food on the bottom of the worm breeding box, and place the worm breeding box in the incubator. After the eggs on the hatching bed hatch into larvae, the larvae will climb into the breeding box from the hatching bed to forage on their own; after all the eggs hatch, step 1 is executed in a loop;

The present invention is a green breeding process for black soldier flies based on solid waste treatment. In the above step 2, a weighing sensor is arranged at the bottom of the breeding tank. Realize automated feeding.

The present invention is a green breeding process for black soldier flies based on solid waste treatment. In the above step 2, a temperature and humidity sensor is arranged in the box, and the data obtained by the temperature and humidity sensor controls the amount of heat conduction medium in the heat medium pipe and the opening of the pipe. And closed, and the air intake volume of the air intake mechanism installed on the side wall of the box is controlled by the data obtained by the temperature and humidity sensor.

The present invention is a green breeding process for black soldier flies based on solid waste treatment. In the above step 5, the ovipositor is a structure composed of two parallel wooden boards with a gap layer in the middle.

The present invention is a green breeding process for black soldier flies based on solid waste treatment, and the number of breeding tanks is the same as the number of days required for the growth of cultured black soldier flies larvae.

The present invention is a black soldier fly green breeding process based on solid waste treatment. The growth period of the black soldier fly larvae is seven days, and the culture tank is set to seven layers. After collecting the culture tank where a certain mature larva is located every day, the hatched Water flies larvae were manually put into the emptied breeding tank.

Compared with the prior art, the beneficial effects of the present invention are:

The process of the invention can realize layered and time-sharing cultivation through the multi-layer designed breeding tank, so as to ensure the continuous shipment of larvae on a large scale; at the same time, through the design of the feeding pipe and the feeding pipe, the automatic feeding can be conveniently realized, and the later stage can be used. The automatic quantitative feeding is realized through the weighing sensor installed at the bottom of the breeding tank and the control valve on the feeding pipe; in addition, the temperature and humidity in the box can be easily adjusted through the design of the heat medium pipe, so as to ensure that the larvae are in in the best growth environment.
