The purpose of egg surface disinfection is to kill pathogenic microorganisms attached to the egg surface and prevent the ants from hatching due to egg shells. The egg surface disinfection of spring silkworms is best carried out 1 to 2 days before silkworms are released. Autumn silkworms are best carried out in the afternoon 1 day before the silkworm is out of the silkworm. The eggs are broken directly on the mountain on that day.
The first egg bath with 0.5% sodium hydroxide solution, liquid temperature 18 ~ 20 °C, wash eggs for 1 minute, remove egg surface glue. Then wash with water, control the water, egg surface disinfection. 36% to 38% of formaldehyde solution, 36% concentrated hydrochloric acid, and water were mixed at a ratio of 1:0.5:10. The solution temperature was 23-25° C. and the eggs were immersed for 30 minutes. After several times of decontamination with fresh water, dry it on a plastic gauze.
The formaldehyde solution will produce a precipitate of trioxymethylene when it is exposed to low temperatures. It is insoluble in water and does not provide disinfection. Failure cannot be used. Commercially available alcohol and mercury thermometers have different degrees of difference and must be corrected before use. The liquid temperature must not be lower than 23°C. Below 23 °C, the lower the temperature, the worse the effect. When the egg surface of spring silkworm eggs is sterilized, it often encounters low-temperature weather. In practice, disinfection containers are often placed in warm water that is 1 to 2°C warmer than liquid medicines. Liquid preparation sequence: Inject acid into water and then add formaldehyde. When sterilized, the silkworms instigated the silkworm eggs once every 5 minutes so that the eggs were fully exposed to the liquid. Autumn silkworm should first cut the four sides of spawning paper to enhance the disinfection effect. At the same time, the egg piles on the spawning paper should be scraped off and put into a yarn bag for disinfection. The key step of the disinfection operation is to take 1 spawning paper, put the egg face down and put it into the liquid, gently press the paper back with both hands, wait until the whole spawning paper is completely saturated, and then increase in the same way, until the end. One day before the silkworm emerges from the silkworm, the embryo of the egg has a silkworm shape and the amount of respiration increases. It is necessary to ensure that the egg is dried within 3 hours to prevent the egg hole from being closed by water for a long time and the embryo suffocates. Persons exposed to sterilized eggs should wear clean clothes in advance and wash their hands on the spot to prevent egg surface disinfection and infection by pathogenic microorganisms.
Eggplant is also rich in nutrients, including protein, fat, carbohydrates, vitamins and calcium, phosphorus, iron and other nutrients.Especially high levels of vitamin P.It contains 750 milligrams of vitamin P per 100 grams, more than many fruits and vegetables.Vitamin P can keep hemal wall elasticity and the physiological function, prevent hardening and rupture, so often eat eggplant, contribute to the prevention and treatment of hypertension, coronary heart disease, by the way, we also provide potatoes, carrots, cabbage, red star apple, fresh red Fuji, fresh fruit, crown pear Fresh Sweet Snow Pear, fresh broccoli, eggplant, fresh new potatoes and Garlic, garlic, Ginger, welcome your order.
