Description

Sterilization and disinfection method in artificial culture of wild giant silkworm
Technical Field
The invention belongs to a silkworm breeding method, and particularly relates to a sterilization and disinfection method in artificial breeding of wild silkworm.
Background
Since the last 80 years, people are always researching how to introduce wild silkworms into domestic rearing for industrial development so as to bring benefits to human better. However, because the wild silkworms have unique habits, the survival rate of the wild silkworms in the artificial breeding process is hardly over 15 percent, so that the good desire cannot be realized until now.
Disclosure of Invention
The invention aims to provide a sterilization and disinfection method for artificial culture of wild silkworm, which can improve the survival rate.
The technical scheme adopted for realizing the purpose of the invention is as follows:
the sterilization and disinfection method for artificial breeding of wild silkworm comprises a food sterilization and disinfection step, wherein the food sterilization and disinfection step is to regularly sterilize and disinfect the bred wild silkworm edible tree and edible tree leaves before the ants emerge, and the sterilization and disinfection is carried out by spraying potassium permanganate solution and then spraying folium artemisiae argyi solution.
The regular sterilization and disinfection is to perform fixed-point and fixed-stump sterilization and disinfection on the silkworm feeding trees and the leaf feeding trees every two days five days before the ants come out.
The potassium permanganate solution is sprayed to sterilize, and the solid potassium permanganate and the water purifying solution are prepared according to the ratio of 2-5: 1000-1800, and the potassium permanganate solution is sprayed to the root from the upper end of the main root of the single root edible tree.
The folium artemisiae argyi liquid is sprayed with the folium artemisiae argyi liquid to sterilize, and the folium artemisiae argyi liquid is prepared by decocting dry folium artemisiae argyi and a water purification solution according to a ratio of 1: 10-20 to 10-13 kg with fire, filtering the folium artemisiae argyi after cooling, adding 150-240 kg of water, and spraying the upper layer liquid on the branch extending and the branch extending leaves of the single-stump edible tree to sterilize.
The method also comprises an outdoor environment sterilization step, wherein the outdoor environment sterilization step is to sterilize and disinfect the environment around the silkworm house by using medical pasteurization liquid and potassium permanganate solution before and after the ants come out.
The sterilization and disinfection of the silkworm house peripheral environment by the medicinal pasteurization liquid and the potassium permanganate solution before and after the emergence of the ants are respectively realized by disinfecting the silkworm house peripheral environment twice by the medicinal pasteurization liquid three days before the emergence of the ants and disinfecting the silkworm house peripheral environment by the potassium permanganate solution with the concentration of two thousandths to five thousandths of a day every 2 days after the emergence of the ants until the silkworm house peripheral environment is five-year old.
The invention also comprises a disinfection and sterilization step for the indoor culture of the wild silkworms, wherein the disinfection and sterilization step for the indoor culture of the wild silkworms is to close the door and window before and after the ants come out and smoke the dried folium artemisiae argyi.
The door and window is smoked by using the dry folium artemisiae argyi three days before the emergence of the ants, the door and window are closed by using the dry folium artemisiae argyi for 10 to 20 minutes every day, and the door and window are opened for ventilation one day before the emergence of the ants;
the door and window is closed after the ants come out for 5 to 7 days, the door and window is closed after the ants come out, the folium artemisiae argyi is used for fumigation, sterilization and disinfection for 10 to 20 minutes, then the door and window are opened for ventilation, the method is carried out until the silkworms enter into the third-instar stage and are moved to outdoor cultivation, and if the silkworms of 4 to 5 instars are cultivated indoors until cocoons are formed, the method is also used for operation.
The screen door and window are additionally arranged on the door and window to prevent insects such as parasitic wasps, aspongopus and the like from invading the door and window to infringe the tencel silkworms.
The invention also comprises a disinfection and sterilization step for the wild silkworm outdoor culture, wherein the disinfection and sterilization step for the wild silkworm outdoor culture is that young silkworms are moved to the outdoor culture after entering the third-instar period, and all single-stump edible trees eaten by the silkworms are fumigated and sterilized by folium artemisiae argyi; a circle of quicklime is scattered around the young silkworm on the periphery of the feeding single-stump feeding tree, so that the aim of sterilizing and disinfecting soil is fulfilled, and the invasion of centipede worms to the wild silkworm is prevented; the giant silkworm is covered by a nylon net for sensitization and prevention of the invasion of birds to the giant silkworm.
The regular folium artemisiae argyi fumigation and sterilization is to fumigate and sterilize folium artemisiae argyi every 4 to 6 days for 10 to 20 minutes.
The fumigation and sterilization with the folium artemisiae argyi is to shield all single-root edible trees eaten by silkworms with a tent and close a window curtain of the tent.
Advantageous effects
Through long-term observation and research of the inventor, the inventor finds that the survival rate of the wild silkworm is difficult to improve in the prior art, the wild silkworm is suitable for the generation of germs under different environments due to the change of the natural climate and the temperature, so that the bacteria in the air circulation exist on animals and plants and are rapidly transmitted on the animals and plants suitable for the propagation of the germs. And the wild silkworm is a susceptible insect. The mode of culturing the wild silkworm at present is stocking in a mixed forest. There is no disinfection treatment for preventing diseases of wild silkworms in living environment and on the leaves (trees) eaten by the wild silkworms. Therefore, the cocoon forming rate of artificially cultured wild silkworms is low, about fifteen percent, and in most cases, the wild silkworms are covered by the whole army. Resulting in failure to form the amount of cocoon filaments required for the industry chain of the wild silkworm. Therefore, the field and industry of wild silkworms are from the hot stage to the cold stage from research to culture. The method stops the spread of infectious diseases by grasping the key link of sterilization and disinfection of the wild silkworm food, and better solves the problem of low survival rate of the wild silkworm. After years of cultivation experiments, good effects are obtained, and the cocooning rate of the giant silkworm is more than 65%.
The technical scheme of the invention is further illustrated by the following examples.
