How to disinfect silkworm tools in the silkworm room before raising silkworms?

Before raising silkworms, the silkworm room and silkworm tools must be strictly disinfected. After the silkworm becomes ill, it can neither inject nor take medicine, and there is no panacea. For the occurrence of silkworm disease, it is necessary to implement the principle of prevention rather than cure, and completely eliminate pathogenic microorganisms before raising silkworms, which is the key to ensuring good silkworm raising.

The disinfection of the silkworm room should be carried out in the order of one dust, two sweeps, three scrapes, four washes, five brushes, and six eliminations. That is, the silkworm room is thoroughly cleaned first, and then thoroughly cleaned with water to fully expose the pathogen. Paint the walls with fresh weathered lime and then disinfect them with chemicals, never missing or dissipating.

The surrounding environment of the silkworm room should be carefully cleaned, garbage should be removed, weeds should be removed, gutters should be dredged, sewage should be removed, and then sprayed with disinfectant.

Silkworm utensils should be fully washed with water, dried or sun-dried, and then placed in the silkworm room for disinfection together. It is best to use tap water for the dispensing solution.

The liquid used for disinfection is mainly used with ditrain, bleaching powder, etc., which should be sprayed and disinfected. If it is impregnated with lime and alkali, it must be impregnated with lime or alkali for the first time, and then used ditrane and bleaching powder for the second time. Generally, a silkworm room needs 1 set of esulfate (125 main agent + 1 package of auxiliary agent) and 25 kg of water; Kilograms of bleaching powder, 35 kilograms of water, fully stirred, wait for 2 3 hours, take clarified water for disinfection.

Small silkworm tools can be impregnated and disinfected with medicinal solution; Small silkworm nets, silkworm plaques, goose feathers, cover cloths for silkworm raising, etc., can be boiled and sterilized for half an hour or steamed on a steaming rack for 40 minutes.

With the increase of the number of feeding periods, the number of residual pathogens is large and widely distributed, and the resistance of silkworms to pathogenic microorganisms is weak, so the disinfection of silkworm tools in the silkworm room before feeding is an important part of disease prevention. Centralized disinfection of the required room tools before silkworm raising can effectively reduce the amount of pathogen residue and cut off the vertical source of infection, which is conducive to less or no disease during the feeding period. Disinfection before raising silkworms should be carried out about 1 week before feeding, the time is too early, and if the sterilized silkworm room silkworm is not properly managed, it is easy to be polluted by toxic and harmful substances or pathogens.

The specific requirements for disinfection are as follows.

1) The room should be cleaned and washed. Before disinfection, it is necessary to carry out a comprehensive cleaning of the silkworm room silkworm tools (including the surrounding environment) to remove silkworm sand, dead silkworm marks, dust, etc., and then rinse the silkworm room and clean the silkworm tools to reduce the number of pathogenic microorganisms attached to the silkworm room silkworm tools, and fully expose the pathogenic microorganisms to improve the disinfection effect. At the same time, place movable utensils in the sun.

2) The agent should be registered and symptomatic. Broad-spectrum disinfectants should be selected to help kill various pathogenic microorganisms, and the registration concentration and correct use should be used according to the instructions for the use of disinfectants. For a certain type of silkworm disease that is prevalent in the region, targeted agents can be used to focus on disinfection.

3) The dosage should be sufficient and sprayed evenly. When disinfection, a sufficient amount of medicine must be used, and the walls, roofs, floors and surrounding environment of the silkworm room should be sprayed thoughtfully and thoughtfully, leaving no dead ends; Whether the silkworm is impregnated and disinfected or sprayed, it must be soaked and sprayed evenly. It must be kept moist for more than half an hour after disinfection.

4) The room should be completely eliminated and managed. The disinfection before raising silkworms in the production is generally based on the silkworm room, silkworm tools, mulberry storage room and other utensils (the large silkworm room is disinfected before use), and these rooms must be fully disinfected, so that one does not leak, and after disinfection, it should be concentrated in one room for proper storage to avoid re-contamination.

Hello, the silkworm room needs to be disinfected regularly. Disinfection should be disinfected when collecting ants and silkworms of all ages, and if there is a disease during the feeding process, it must be disinfected again in time. Disinfection must be a certain stove is to be faintly regretted without dead ends, and the ratio of potions should be reasonable.

Yes, so that the animals can grow better, under normal circumstances, they need to be disinfected every 7 days.

The first point is that the first type of Sakura must be regularly disinfected to the baby, and the limbs are so effective, and the second point is that the time of basic disinfection is about a month, which is relatively good, and Song Liang is very good.

Da Sleep refers to:The only time in the silkworm stage is that the 4th instar sleepsWhen the silkworm is in the big sleep period, the sleep is slow, and the sleeping time is longer from seeing the sleeping silkworm to all the sleep, if the management of the silkworm farmer is not in placeSome silkworms can only sleep with hunger, which is extremely detrimental to the health of silkworms, and may also cause some silkworms to be old and uneven, or even unable to grow and form cocoonsTherefore, it is very important to deal with the sleeping of silkworms during the period, and I will talk about what problems should be paid attention to in the management of silkworms during this period.

The first thing is to do a good job of pre-sleep treatment。In this step, to make the silkworm full and then sleep, will sleep with the best mulberry leaves for multiple feeding, but each time the amount of mulberry should be properly controlled, mulberry leaves should be selectedFresh leaves, and finely chopped. In addition, the green should be timely to pick out the sleepy and diseased silkworms, so that the silkworms after the green growth and development are neat, which is conducive to the batch management in the later stage.

It is recommended that when the cocoon is applied at the 5th instar stage, it is also applied in batches, so as to alleviate the labor shortage during the cocoon application and make the quality of the cocoon better.

The second is to pay attention to sleep protection. What we should pay attention to here is the control of temperature, the temperature in sleep should be lower than that in the mulberry, the difference between dry and wet is about in the early stage, and about 2 in the later stage, the word I use here is "left and right", and I want to tell you that the specific number is actually just a reference. Sleep protection also includes other elements, such as avoiding strong winds and vibrations, and the light should be evenly dim, etc., to prevent these problems from causing harm.

Finally, I have to talk about food. No matter what kind of environment, the food should be timely, "timely" refers to the time point when the head of the silkworm is basically light brown, after disinfection, the selection of fresh tender mulberry leaves to feed the silkworms, generally about 2 hours after feeding to the second mulberry, to ensure that the mulberry leaves are even, and the amount is sufficient.

It's better for us to grow my own mulberry trees and provide fresh mulberry leaves for silkworms to eat. Now there are also mulberry leaves sold in the market, not to buy too much at one time, mainly to let silkworms eat fresh mulberry leaves.

In the food provided to silkworms, it is necessary to pay attention to the fact that there is no moisture. Mulberry leaves can be washed and dried before being eaten by silkworms, or they can be eaten directly by silkworms without washing, but there can be no moisture.

If it is a large-scale silkworm raiser, it is generally made of bamboo to hold the silkworms. If it is a small one to raise a few silkworms, we can fold a cardboard box with silkworms. Always make sure that the silkworms have enough space to move.

We only need to provide mulberry leaves to the silkworms, but we should pay attention to the amount of each stocking. Too much will lead to waste, too little will lead to starvation. It's important to look for the sweet spot for volume.

In such a situation, I think we must deal with the problem of going to bed, we must let the silkworms eat enough before sleeping, we must choose fresh leaves, we must protect them during sleep, the temperature should be kept at about 3 2, and we must ensure that the mulberry leaves are uniform and sufficient.

First of all, we must ensure the other party's diet, we can't sleep hungry, we need to pay attention to the health of silkworms, pay attention to the cocoons of silkworms, and these are very important.

Attention should be paid to the management of silkworms, the control of temperature, the control of the humidity of silkworms, the treatment of silkworms, and the growth state of silkworms.

Hello, landlord:

Correct disinfection methods and requirements.

In order to improve the disinfection effect, the disinfection steps are required:

A sweep. Thoroughly clean the jamsil and its surroundings).

Second wash. Wash them all.

silkworm tools and cement floors).

Three scrapes. Scrape off the mud from the epidermis of the silkworm chamber).

Match 4. Disinfect the silkworm room with chemicals).

Conditional silkworm room before disinfection.

It can be fully painted once with lime mortar.

In the process of disinfection, it is required to do six things:

The silkworm room should be cleaned:

Thoroughly clean the inside and outside of the silkworm room, so that the disease is not a hiding place, and the dust swept out should be kept away from the pile outside the silkworm room.

Put it and make fertilizer to prevent re-contamination. The requirements are met: there is no dust at the sight, no dust at the touch of the hand, a layer of ground scraping, and the inside and outside are cleaned.

Silkworm utensils should be washed cleanly:

Take all the large and small silkworm tools to the flowing river and wash them thoroughly, and they can be used if possible.

Wash with alkaline water, after washing.

Both large and small silkworm tools are dried. When washing, it is required that silkworm tools do not leave silkworm sand, dead silkworms and stains, and wash them piece by piece. The purpose of sweeping is to remove the pathogen or make.

The pathogen is fully exposed, thus improving the disinfection effect of the agent.

The medicine should be properly dispensed

The drug is prepared according to the standard, grasps the properties of the drug, meets the conditions of action, and gives full play to the efficacy.

The liquid medicine should be sprayed evenly:

Liquid disinfectants, such as disinfection net, lime slurry, etc., are required to be sprayed with a sprayer, the amount should be sufficient, and the spraying should be even.

Seek to be comprehensive, leave no dead corners, and be able to maintain a moist state for half an hour.

When gas disinfection, the gaps between doors and windows should be closed to prevent air leakage.

Disinfection should be comprehensive:

It is required to disinfect the silkworm room, cluster room, etc., and disinfect all kinds of silkworm tools, indoor and outdoor comprehensive disinfection. Disinfection is necessary.

Complete it all at once, and remember to use it as it is used or eliminated a little.

After disinfection, it should be managed well:

After disinfection, it is necessary to prevent the re-invasion of pathogens and minimize contamination.

It is required not to enter and exit the sterilized silkworms casually.

room, mulberry storage place; Unsterilized silkworm tools are not taken into the silkworm room for stacking; Sterilized silkworm tools should not be used arbitrarily.

The tools required for silkworm raising are collectively referred to as silkworm tools. There are many types of silkworm tools that should be prepared before raising silkworms. It can be divided into the following categories according to the application.

1) Disinfection utensils.

Sprayers, buckets (or tanks), leather tubes, sterilizers, brooms, etc.

2) Ant collection utensils.

Silkworm seat paper, silkworm plaque, goose feathers, ant cotton paper, small silkworm nets, etc.

3) Feeding utensils.

Silkworm frame (trapezoidal frame or triangular silkworm platform), silkworm plaque, bamboo pole, plastic film, anti-drying paper, tool, dry and wet thermometer, etc.

4) Give mulberry utensils.

Mulberry cutting knife, mulberry cutting board, scale, mulberry rack, plastic box for mulberry leaves, stepping stool, stepping board, etc.

5) Sand removal and other utensils.

Silkworm nets, sand baskets, buckets, dustpans, brooms, sprayers, etc.

6) Mulberry picking and storage utensils.

Mulberry baskets, mulberry scissors, mulberry storage tanks, air cages, cover mulberry cloth, etc.

7) Wrapping utensils.

Crumbs (checkered or folded or centipedes, etc.), reed curtains, crests, etc.

In addition to the necessary utensils, a certain amount of substances must be consumed: such as silkworm medicine, lime, straw, charred bran, fuel, etc.

A box of silkworm seeds required silkworm tools and consumables for reference.

The mulberry leaves fed by silkworms in each time period are also different, and special attention should be paid to the fact that in order to ensure the initial development, the mulberry leaves in the early stage must be relatively tender.

Silkworms do not need water when feeding, and its water ** all comes from mulberry leaves, so every time it is fed, it is as fresh as possible, and the water of the leaves should be cleaned.

Feeding should pay attention to the mulberry leaves can not be fed all at one time, at least divided into two times in the morning and evening for feeding, feeding time from 7 o'clock in the morning to about 10 o'clock in the evening, feeding 4 to 5 times in the middle, mulberry leaves must be covered on the silkworm body, so that it is conducive to eating, the thickness of 3-4 layers of mulberry leaves.

1. Mulberry leaves should be reasonably collected, transported and stored. Try to pick the leaves in the morning or evening, and transport them with the picking, and loosen them quickly. After the collected mulberry leaves are shaken and loosened, they are put into the mulberry storage pond or mulberry storage room, and stored reasonably to prevent the wind from blowing or accumulating heat and deterioration, resulting in the waste of mulberry leaves.

2. In the juvenile silkworm stage, kang bed (room) and plastic film are used to cover and breed to facilitate heat preservation and moisturizing, so that mulberry leaves can be kept fresh. After feeding the silkworms during the silkworm period, the doors and windows should be closed appropriately, and about 70% of the mulberry leaves should be eaten away, and then the doors and windows should be opened for ventilation, which can effectively prevent the mulberry leaves from withering.

3. The suitable temperature of large and small silkworms is respectively, within the appropriate temperature range, the appetite is strong, the residual mulberry leaves are reduced, and the conversion rate of leaf filaments is improved.

4. Labor-saving sericulture technologies such as small silkworm plane three-dimensional one-time breeding, all-age two-time breeding, and large silkworm strip mulberry breeding not only improve the efficiency of silkworm raising, but also help silkworms eat mulberry, saving about 5% of mulberry leaves compared with ordinary breeding.

Those who eat mulberry leaves are called mulberry silkworms. Those who eat the leaves of the oak tree are called silkworms. When it grows up, it spins silk and forms cocoons and becomes an adult --- silkworm moth.

After receiving the silkworm seeds, place the silkworm seeds in the prepared silkworm box, which is generally an ordinary paper box, but ensure that the silkworm box is clean and odorless. From the date of delivery, the silkworm seeds will hatch naturally into silkworm ants in a room temperature environment with a temperature of 21-29 degrees Celsius, and will naturally hatch into silkworm ants for about 11 days (including the delivery time). Silkworm ants have an appetite about 40 minutes after hatching, and the feeding process begins at this time.

Take out the prepared fresh young mulberry leaves from the refrigerator, wait for the mulberry leaves to return to room temperature, cut them into small pieces with a knife and put them in the silkworm box, and the silkworm ants will automatically climb onto the mulberry leaves to eat. It generally takes about 27 days (divided into 5 instars) for silkworms to hatch and cocoon up the mountain from hatching to hatching. The first to third instar silkworms should be fed with more tender mulberry leaves, and the fourth and fifth instar silkworms can use ordinary mulberry leaves.

Silkworms are suitable for growing in an environment with a temperature range of 22-29 degrees Celsius, and their optimal growth temperature is around 27 degrees Celsius. The mulberry leaves that a silkworm eats in its lifetime are about 25 grams. For example, if you feed 40 silkworms, you only need 1 kg of mulberry leaves.

But in the actual feeding process, there will be some mulberry leaves wasted, so that more mulberry leaves will be needed. After the fifth instar, the silkworm should stop eating mulberry leaves and start looking for a suitable place to spin silk and form a cocoon (also called a mountain cocoon). In rural areas, grassy hills or pine branches made of straw are generally used as silkworm hills.

Silkworms that are fed as pets can be replaced by a cardboard box divided into many small compartments. Precautions for sericulture.

1. Mulberry leaves are kept fresh 1. Place mulberry leaves in the refrigerator (about 5 degrees Celsius) to prevent deterioration. 2. Tie the mouth of the plastic bag tightly to slow down the drying and dehydration time of mulberry leaves.

2. Feeding of silkworms 1. Take out the mulberry leaves from the refrigerator for a few minutes to restore the mulberry leaves to room temperature before feeding. 2. Do not wash mulberry leaves and keep them in a natural state. 3. For the feeding of second-instar silkworms, please choose tender mulberry leaves, 1-2 pieces per day.

4. The feeding time can be selected in the morning or noon.

3. Other precautions 1. Do not catch silkworms by hand, and use the soft bristles of the brush to catch up; 2. Do a good job of cleaning the silkworm house every day.
