Technical Field

The invention relates to the technical field of harmless treatment and resource utilization of livestock farm feces, in particular to a system for treating livestock and poultry feces by breeding hermetia illucens and application thereof.

Background

The black soldier fly is an insect of hermetia illucens of hermetia diptera, and can eat organic waste to produce high-quality organic fertilizer and high-value animal protein after passing through egg, larva, prepupa, pupa, adult and other insect states all the time. The animal manure is utilized to treat and recycle the animal manure due to the characteristics of rapid propagation, large biomass, wide feeding property, high absorption and conversion rate, low feeding cost, good animal palatability and the like. Livestock and poultry manure is treated by the soldier fly larvae, so that manure accumulation can be effectively reduced, odor is reduced, mosquitoes and flies are prevented, organic fertilizer and insect body protein are obtained, and the organic fertilizer and the insect body protein have good environmental benefit and economic benefit. At present, pig manure of a black soldier fly processing farm receives wide attention of breeding enterprises. Because the requirement of ovum hatching and larva feeding on the humiture is higher, the hermetia illucens breeding conditions in different stages all distinguish, if lack of necessary management, excessively rely on the autonomic growth and the self-collection of hermetia illucens, can lead to reducing faecal treatment effeciency, reduce larva output, increase processing cycle to influence the output of polypide protein, and excrement and urine can not in time effectively handle and can lead to stink and fly to obtain effective suppression. Therefore, the method for simply and effectively utilizing the pig manure to breed the hermetia illucens and obtaining the high-quality insect body protein and the organic fertilizer is of great significance.

The temperature in the Yunobu region is proper, the method is suitable for the growth and the propagation of the hermetia illucens, the hermetia illucens larvae or ova can be quickly obtained by artificially breeding the hermetia illucens, and the hermetia illucens can be sold to livestock farms as commodities. However, in the prior art, most of the artificially cultured hermetia illucens adopt a culture room made of a glass material or a daylighting plate at the top, the characteristic of intense sunlight in the cloud and precious regions is ignored, the temperature in the culture room can be raised after sunlight directly irradiates into the culture room in the daytime, the adult is killed due to temperature change, and common workers can frequently enter and exit the adult culture area when feeding the adult, so that the hermetia illucens can accidentally escape in the free space where the workers enter and exit, and the quantity of the hermetia illucens is unnecessarily lost. The heisui river horsefly is bred through breeding the pond mostly, generally breed the pond and build for cement mostly, then drop into the larva of the pig manure thick liquids that the preliminary treatment is good and the worm's ovum hatching, need turn once every day, because worm's excrement volume is bigger than the pig manure, so the material can increase, in time clear up remove, turn over the pond at present and strike off unnecessary material and usually by artifical manual handling, under the condition of breeding in batches, the intensity of labour and the work efficiency that have improved the staff undoubtedly also can't guarantee. Moreover, the material that the pond clearance was come out from breeding is the worm sand, is that the polypide mixes together with the worm excrement, needs to separate the polypide and the separation of worm excrement, and the polypide utilizes as protein feed, and the worm excrement utilizes as the fertilizer, and prior art's separation of worm excrement is mostly through artifical screening, wastes time and energy, can not be fine carry out worm excrement separation work.

						Amount of egg laying (g)	89	142	198	211	92

According to the experiments, the egg amount collected by the treatment groups at 20-24 ℃, 24-28 ℃ and 35-40 ℃ is obviously less than that of the other two groups, the mating condition of adult flies is observed during the experiment, the experimental groups at 20-24 ℃ and 24-32 ℃ are fed at the temperature, the adult flies mate less, the mating quantity of the adult flies in the treatment groups is more and more active and the mating quantity is more, and the treatment groups at 35-40 ℃ are dead first compared with the other three groups when the temperature is 28-32 ℃ and 32-35 ℃. The temperature of 28-35 ℃ is a temperature range suitable for the mating and egg laying of hermetia illucens.

1.2 Effect of different nutrient supplements on egg laying of Hermetia illucens

The hermetia illucens needs to supplement moisture in the adult stage, because the mouth organ degeneration does not eat, nutrient substances mainly depend on the accumulation of larval stage, theoretically, the adult only needs to supplement moisture to complete mating and oviposition, but still needs a period of time from eclosion to mating, oviposition, nutrient substances stored by some adults with dysplasia in larval stage are not enough to support normal life activities, so that the adult can be supplemented with nutrients in water, and brown sugar, honey, milk powder, white sugar and the like can be added as the nutrients. The experiment aims at selecting proper supplementary nutrient substances, putting pupae to be eclosized into 4 adult culture rooms respectively, supplementing nutrient solution 3kg each time every day, preparing 5% of brown sugar water, white granulated sugar water, honey water and milk powder solution respectively, and controlling the temperature at 28-35 ℃. Collecting eggs every day, weighing and counting until all adults die.

			8-12	16.65±0.90	11.82±0.84
12-16	15.43±0.88	10.50±0.70

Experimental results show that when the stacking thickness is 8cm-12cm, the larva grows better than the stacking thickness of 2cm-4cm, 4cm-8cm and 12cm-16 cm. Therefore, the thickness of the pile is selected to be 8cm-12 cm.

4.3 experiment of pig manure addition

When the hermetia illucens larvae begin to eat the pig manure, the feeding amount is gradually increased along with the growth and feed intake of the hermetia illucens until a certain feed intake is reached, and excessive addition can result in excessive pig manure, so that the aim of completely treating the pig manure cannot be fulfilled. The experiment aims to obtain the proper addition amount of the hermetia illucens in the process of feeding the pig manure. The larvae of 3-5 days old are put into a breeding pond which is divided into 1 square, 5g, 10g, 15g, 20g and 25g of larvae hatched by ova are respectively put into the breeding pond, and then the pretreated pig manure slurry is put into the breeding pond. Firstly, adding the feed according to the ratio of 10kg (pig manure)/100 g (ova hatching larvae), continuously feeding the larvae after feeding, adding 0.5kg each time, and culturing for 12 days. In the culture process, the pond is turned over once every day, the height of the stockpile is kept between 8 and 12cm, if the stockpile is too high, redundant insect sand is cleared (generally, the culture pond is cleared once every 2 days after being fully stocked), the pond is turned over, the materials are fed again, and the environmental temperature is kept between 15 and 30 ℃. The daily feeding condition of pig manure is recorded, and the body length of the larvae (10) and the body weight of the hundred worms are recorded after the feeding is finished.

			25g/㎡	16.21±1.54	10.88±0.84
30g/㎡	16.07±1.57	10.72±0.34

The experimental result shows that the density is 5g/m²，10g/m²The larva activity is general, and the growth condition is general. Mainly because larva density is low, and it is not many to throw and feed excrement and urine for when the excrement and urine pile body paved the plastic box, pile body height was less than 8cm, leads to the temperature not high, thereby the larva activity is not strong, if make excrement and urine pile body pile height be greater than 8cm, then only partial region satisfies the condition, can't use the plastic box completely, causes the space extravagant. The density is 15g/m²，20g/m²And when the larvae are active, the excrement is fed for 5 th and 6 th days, the plastic box is fully paved with excrement piles, the height of the piles is greater than 8cm, and the temperature can be kept, so that the larvae are active. The density is 25g/m²，30g/m²Larvae are active but too dense, which can result in excessive temperatures and escape. Therefore, the optimum feed density is 15g/m²-20g/m²。

4.5 Effect of ambient temperature on the larvae

The environmental temperature can influence the growth of hermetia illucens larvae, the efficiency of the hermetia illucens for feeding pig manure is reduced when the temperature is too high or too low, and the death of the hermetia illucens larvae can be influenced even when the temperature is too high. The experiment aims at researching the influence of different environmental temperatures on hermetia illucens larvae, the larvae of 3-5 days old are put into plastic boxes and respectively put into cultivation rooms with controllable temperature for cultivation, 10g of larvae hatched by ova are put into each plastic box, then pretreated pig manure slurry is put into each plastic box, the water content of the slurry is 65% -80%, the temperatures are respectively set to be 10-15 ℃, 15-20 ℃, 20-25 ℃, 25-30 ℃ and 30-35 ℃, and the pig manure slurry is fed every day according to the ingestion condition and is cultivated for 12 days. And (5) observing the growth condition of the hermetia illucens larvae, and recording the body length and the body weight of the larvae (10) after the end of the process.

			10℃-15℃	10.91±1.82	6.49±0.55
15℃-20℃	14.38±1.97	9.57±0.53
			20℃-25℃	14.85±1.28	10.17±0.78
25℃-30℃	15.95±1.20	12.11±0.41
			30℃-35℃	15.41±1.02	10.77±0.56

Experimental results show that when the environmental temperature is 10-15 ℃, the growth condition of larvae is not good, when the environmental temperature is 15-35 ℃, the body length and the body weight of the larvae are not greatly different, but when the environmental temperature is 35 ℃, the larvae die in the later stage. Therefore, the temperature of the hermetia illucens larvae is controlled to be 15-30 ℃ when the pig manure is treated.
