Embodiment 1
[0027] The first step is to wash with warm water: put 1.5 kg of bat's eggs in the nylon gauze bag into the Scrub in warm water for 1 to 3 minutes, then remove water. This method is mainly to remove dust, scales and residual wings attached to the egg surface.
[0028] The second step is alkali dipping: first put 5 kg in a plastic bucket Clear water, then put 25 grams of sodium hydroxide into it, stir it with a wooden stick and pour it into a small plastic basin.
[0029] The basin is filled with clear water at 18°C. After that, the operator should wear latex gloves, hold the mouth of the bag, put the bat eggs into a small plastic basin filled with lye, start the timer, and gently rub the bat eggs. The lye rapidly changes from colorless to dark brown. When the timing clock shows the process of soaking in alkali to 55 seconds, the bat's ovum is lifted from the basin to control the alkali solution for 3 seconds and immediately put into the large plastic basin for dealkaliza...
Embodiment 2
[0040] Use 1Kg bat eggs, wash them with warm water, then dilute them with silver hydrogen peroxide ion at a ratio of 1:200, soak for 20 minutes; dry them in the air, and then use hydrochloric acid, formalin and water for disinfection at a ratio of 1:1:18 The liquid is disinfected; the use concentration is 20mg / m 3 The ozone treatment, other temperature and humidity conditions are constant, the average hatching rate of bat eggs is 92.5% (the vast majority of non-hatched bat eggs are non-fertilized eggs), and the hatching rate of removing non-fertilized eggs is 98.9%, depending on for normal hatching.
Embodiment 3
[0042] Use 1Kg bat eggs, wash them with warm water, then dilute them with silver hydrogen peroxide ion at a ratio of 1:150, soak for 20 minutes; dry them, and then use hydrochloric acid, formalin and water for disinfection at a ratio of 1:1:18 The liquid is disinfected; the use concentration is 20mg / m 3 Treated with ozone, the average hatching rate of bat's eggs was 90.4% (the vast majority of non-hatched bat's eggs were non-fertilized eggs), and the hatching rate of removing non-fertilized eggs was 96.8%, which was regarded as normal hatching.

Abstract
The invention discloses a disinfection treatment method for hepialus armoricanus eggs, and relates to the field of artificial cultivation. According to the method, ozone is used for auxiliary disinfection, the concentration of acid and alkali is further reduced, and hurt to operators is further reduced. According to the specific scheme, the disinfection treatment method comprises the following steps: S1, cleaning the hepialus armoricanus eggs with warm water; S2, removing water from the surfaces of the hepialus armoricanus eggs; S3, carrying out alkali leaching by using a sodium hydroxide solution with the mass fraction concentration of 0.2%-0.3%; S4, diluting the hydrogen peroxide silver ion disinfectant stock solution and water according to the ratio of 1:150-1:250, and soaking the hepialus armoricanus eggs for 15-25 minutes; S5, airing the hepialus armoricanus eggs again; and S6, before the hepialus armoricanus eggs are transferred to the ground, adopting ozone with the concentration of 15-25 mg/m<3> to disinfect the ground where the hepialus armoricanus eggs are hatched and provided with plant root systems for 15 minutes, and then transferring the hepialus armoricanus eggs to the underground to be hatched. According to the disinfection treatment method for the hepialus armoricanus eggs, the hepialus armoricanus eggs are disinfected through ozone, and the operation time is short.
Description
technical field [0001] The invention relates to the field of artificial cultivation, more specifically, it relates to a method for disinfecting bat moth eggs. Background technique [0002] Cultivation conditions The artificial cultivation of Cordyceps sinensis mainly involves the preparation of strains and insects. The biggest difficulty is the source of insects. At present, insects are mainly collected in the wild. Artificial propagation of this kind of insects still has certain difficulties, which restricts the progress of artificial cultivation. . [0003] In the prior art, disinfection is mainly carried out by formaldehyde, bleaching powder, hydrochloric acid, sulfuric acid and chlorine dioxide; in the above-mentioned disinfection methods, bleaching powder has the disadvantage of unstable use and is prone to failure; and the use of chlorine dioxide has the disadvantage of unstable use. , and is toxic, causing great damage to operators; in the case of using a mixture of ...
