Problems solved by technology

[0003] At home and abroad, the focus of current research on black soldier fly larvae is to increase the yield of black soldier fly larvae and shorten the duration of larvae, but there are few studies on the suitable conditions and specific effects of black soldier fly larvae directly treating dry manure in large-scale pig farms
Moreover, in the existing documents, pig manure is mixed with mixed feed to raise black soldier fly larvae together, which leads to high feeding cost of black soldier fly, and the amount of pig manure that can be ecologically treated is limited, so there are serious shortcomings

Embodiment 1

[0030] A kind of ecological breeding method that black soldier flies process pig manure, comprises the steps:

[0031] (1) Larvae treatment: collect about 20 grams of black soldier fly eggs produced on the same day, and ensure that the difference in spawning time of the collected eggs does not exceed 3 hours. Lay the collected eggs horizontally in the breeding plastic box, and cover the eggs with a layer of gauze, then put the breeding plastic box covered with gauze into the artificial climate box to hatch, and the temperature in the artificial climate box Set to 28-32° with a humidity of 68-70%. After the larvae appear, add bran, alfalfa meal, and corn flour mixed feed (for details of the mixed feed, refer to the article "Black Soldier Fly Artificial Breeding and Its Application" published in "Agricultural Development and Equipment" in 2015 by Tang Xiaoqin, Lu Jie, and "Agricultural Development and Equipment"), And continue to raise to 4 days old.

[0032] (2) Treatment of ...

Embodiment 2

[0035] Steps (1) and (2) of the ecological breeding method for black soldier flies processing pig manure provided in this example are the same as steps (1) and (2) in Example 1. In the step (3) of this embodiment, ensure that the ambient temperature is 30° C., and the rest are the same as in the step (3) in the first embodiment.

Embodiment 3

[0037] The step (1) of the ecological breeding method of the black soldier fly processing pig manure provided in this embodiment is the same as the step (1) in the first embodiment, and the steps (2) and (3) of the present embodiment are as follows:

[0038] (2) Treatment of water content of pig manure: take some fresh manure and bake until the water content is 75%, and the water content of manure is calculated as: water content of manure = (weight of unbaked manure - weight of manure after drying) / unbaked manure Weight × 100%.

[0039] (3) Treatment of pig manure inoculated with larvae: Insert 100 4-day-old larvae in step (1) into the pig manure with a water content of 75% and a weight of 400 g in step (2), and ensure that the treatment environment temperature is 28°C, continuous treatment for 11 days.

Abstract

The present invention discloses an ecological breeding method for treatment of pig manure by employing black soldier fly larvae. The method comprises three steps of: larva processing, pig manure watercontent processing, and larva inoculation pig manure treatment. The black soldier fly larvas produced at the same day are selected and collected to put into a manual climatic box for incubation, andmixed provenders are added to the manual climatic box for breeding of larvas for 4 days after the larvas are produced. A plurality of fresh faeces are taken out to dry to faeces with water content ina range from 70% to 80%, the larvas of 4 days old are accessed on the faeces, the access proportion is that: each 100g of faece dry matters are accessed with 100 larvas of 4 days old, the environmenttemperature is in a range of 28-30 DEG C, and the processing days are 9-11 days. The ecological breeding method for treatment of pig manure by employing black soldier fly larvae employs early-stage larvas of the black soldier fly larvae to simply and effectively treat a lot of fattening house pig manure generated by a large-scale pig farm, does not need addition of any larva diet in the faeces inthe treatment process and does not need grading supplementing of the faeces, and therefore the screened manure treatment condition is less in steps and higher in controllability, and the ecological breeding method for treatment of pig manure by employing black soldier fly larvae is more helpful for popularization and application in the farmers and reduction of the treatment cost.

Description

technical field [0001] The invention belongs to the field of sewage and manure treatment, in particular to a method for treating pig manure. Background technique [0002] In recent years, my country's livestock and poultry breeding industry has developed rapidly and has become a pillar industry for agricultural and rural economic development. However, a large amount of breeding waste has not been effectively treated and applied, which has become a major problem in environmental governance. According to data from the National Bureau of Statistics, at the end of 2017, there were 433.25 million live pigs in my country, and 688.61 million live pigs were sold. Once a large amount of excrement is piled up or handled improperly during the production process, it is very easy to cause serious pollution to the environment. How to adopt an economical, efficient and applicable treatment mode based on fertilizer use has become a hot spot in the research of livestock and poultry manure ...
