Where to raise silkworm seeds, and where is the best place to raise silkworms?

In the shoe box, just feed bamboo shoots or mulberry leaves.

Brighter place.

Silkworms are more sensitive to light and temperature, and the early young silkworms generally need to avoid light exposure, and hatch slowly in the presence of light, and the temperature is controlled at about 25-30. In the early stage of incubation, the temperature should be kept at around 30-33, and the control of light can be slightly loosened at this time, but it is still necessary to try to avoid continuous bright light. In the middle and late stages, the temperature is controlled at about 25, and the environment can be kept bright occasionally, but it is still mainly dim.

Silkworms are generally raised in boxes, which is conducive to management and the growth of silkworms. From the perspective of the fragility of silkworms, first of all, the silkworm box must be disinfected in place, and it is best to use the sun for a few days after disinfection to achieve the effect of natural disinfection.

It's best in the shoe box that you don't use, and there are a few more holes on it.

When I was a child, I raised silkworms in boxes.

It's best to put it in a box that you don't use.

On the ground, I have been raising silkworms for ten years. My family raises more than 20 silkworm eggs at a time.

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 fresh.

1. Place the mulberry leaves in the refrigerator (about 5 degrees Celsius) to prevent spoilage.

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 and wait 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. Don't catch silkworms with your hands, use the soft bristles of the brush to catch up;

2. Do a good job of cleaning the silkworm house every day;

Methods of raising silkworms: 1. Ventilation to raise silkworms. The sericulture room must be ventilated to prevent the silkworms from being hot and stuffy.

Second, the silkworm is not suitable for wetness. The resistance to high temperature and humidity is the weakest in the silkworm stage, the relative humidity needs to be kept at 75%, and the silkworm seat should also be kept dry, which can not only improve environmental hygiene, but also increase the rate of silkworm health.

3. Silkworms should not be fed bad mulberry. The growth and development of silkworms mainly rely on mulberry leaves to provide nutrition, such as feeding poor mulberry leaves, which will affect the normal growth and development of silkworms, and even induce silkworm disease. The main types of bad leaves are:

Immature leaves, old leaves, drought-damaged leaves, steaming leaves, soot leaves, withered leaves, pesticide polluted leaves, etc.

Fourth, the leaf foot mulberry is good to promote satiety. In order to fully feed silkworms, the following tasks must be done: 1

First of all, it is necessary to carry out the first class of mulberry leaf production, do a good job in the balance of leaf silkworms, how many mulberries, how many silkworms to raise, and not to raise too many silkworms, which is the premise. Secondly, according to the mulberry leaf consumption standard of each age, combined with the growth of mulberry trees and the changes of the day, the amount of mulberry picking should be determined according to different ages, and enough mulberry leaves should be prepared every day. 2.

It is necessary to ensure that the leaf quality is good, and make reasonable arrangements for the collection, transportation, storage and feeding of mulberry leaves. In terms of mulberry picking, do it in the morning, eat it during the day, pick it in the evening, eat it at night, and try not to eat overnight leaves. The large silkworm period uses a lot of leaves, and there should be a special mulberry storage room to effectively keep fresh, not wilt and prevent steaming.

In the method of feeding mulberry, it is necessary to pay attention to the silkworm after giving mulberry, close the doors and windows for 1 to 2 hours, about 70% of the mulberry leaves, and then open the window courage, which can reduce water evaporation and help improve the rate of eating less silkworm. 3.It is necessary to do a good job of making up for mulberry.

From the third silkworm of the fifth instar silkworm, it is the period when the amount of mulberry is the highest before the old maturity, and the silk gland grows the fastest at this time, and the amount of foot leaves must be given. After each mulberry, I see that there is a blank space in the silkworm platform, and I want to make up for the mulberry and increase the feeding, and I can't relax.

Fifth, disease prevention and disinfection pay attention to hygiene. During the whole period of silkworm breeding, in addition to doing a good job in the sanitation of the silkworm raising environment and the disinfection of silkworm tools in the silkworm room, it is also necessary to: 1

Silkworm breeders should sprinkle water first and then sweep the floor, wash their hands first and then feed the silkworms, and develop good hygiene habits. 2.During the silkworm period, the silkworm body should be sprayed with fresh lime powder every day, and the silkworm body and silkworm seat should be disinfected once with disinfectants such as the silkworm disease prevention No. 1.

Every few days, the silkworm room, mulberry storage room and silkworm environment are disinfected with bleaching powder to kill pathogenic microorganisms in the silkworm room and its surrounding environment. 3.During the silkworm period, the silkworm sand should be removed frequently, and the dry materials should be used frequently, so as to remove the sand once a day, so as to facilitate moisture absorption and isolation of silkworm sand, so that the silkworm seat is often kept dry and hygienic.

3.It is also necessary to prevent pesticide poisoning and various harmful gases from harming silkworms.

The suitable temperature of the single is 25 to 28 degrees, and the mulberry leaves given to him must not have water, otherwise they will eat bad stomach, and the boat should use relatively tender leaves, and deal with the sick in time to avoid the spread of silkworm disease! Spray insecticides in rooms where silkworms can no longer be raised, and do not turn sleeping silkworms at will.

3.You can also eat elm leaves, dried tea leaves, castor leaves, but if there are really no mulberry leaves

Do a search on the web. "Silkworm breeding"There is an answer.

Generally speaking, it can be stored by refrigeration, it is worth noting that it must be refrigerated, not frozen, because below zero, the silkworms may all die. The method of refrigerated storage is to confirm that the color of the silkworm eggs has changed to diapause ten days after laying eggs, and then put the silkworm eggs in the refrigerator at 5 degrees Celsius, which can be stored in disposable lunch boxes or plastic bags.

When refrigerating in the refrigerator, it is necessary to pay attention to the silkworm eggs to keep them dry, without water droplets, and not in the refrigeration position to prevent freezing.

Generally, after 100 to 120 days of storage, silkworm eggs are basically diapaused. If the silkworm eggs laid in the first half of the year want to be preserved in the second half of the year, the first half of the time can be considered to be stored at room temperature, about the end of the year between October and December can be stored in the refrigerator, to the spring of the next year, when the mulberry leaves germinate, the silkworm eggs can be hatched.

Silkworm nutrients

In addition, the main substances that generally constitute silkworm eggs are 65% water, 20% protein, 10% lipids, 4% carbohydrates, inorganic salts, etc. Protein is the basic unit of amino acids molecule is highly coincident, accounting for the main part of the dry weight, is an important material for the structure of the egg shell or egg cell, in addition to many protein molecules have the role and function of enzymes, the main component of the egg shell chitin, is glycine or histidine and other hard proteins, accounting for 22-29% of the dry weight of the egg shell.

Wrap it in a cotton ball, and put it next to the heater, not too close, and the temperature is moderate, just put it in a box.

Wrap in newspaper, plastic wrap and put in the refrigerator!

Put it in a place where there is no sunlight!

How to preserve silkworm eggs:

After the silkworm eggs are laid, they are treated by bathing and finishing, winter refrigeration, intermediate temperature sensing, etc., and its characteristics are as follows:

1. The first refrigeration of silkworm eggs in winter starts when the embryo is in the early stage of overwintering, the first refrigeration temperature is 0 -1, and the first refrigeration time is 100 120 days;

2. After the end of the first refrigeration, the silkworm eggs are carried out at a temperature of 10 15 for the first intermediate temperature sensing, and the embryo develops to the overwintering stage III IV stage, and then transferred to the second refrigeration, and the refrigeration temperature is 1 5 3 5; During the second refrigeration period, the silkworm eggs required for the use of spring silkworms in late April and early May will be refrigerated 3 5 days in advance, and the embryos will be adjusted to the critical period with a temperature of 10 15 to be used after greening;

In the middle of the month, the second refrigeration is ended, and the second intermediate temperature is sensed for the silkworm eggs with a temperature of 10 15, and after the embryo develops to a critical period, it is returned to the environment with a temperature of 1 5 3 5 for the third refrigeration; During the third refrigeration period, silkworm seeds used in summer silkworms in early mid-June or early autumn silkworms in mid-to-late July should be provided, and the third refrigeration should be directly completed according to the required time, and used after greening;

End the third refrigeration in the first half of the month, use the temperature of 10 15 to carry out the third intermediate temperature sensing of the silkworm species, wait for the embryo to develop to the sulcus emergence stage, and then carry out the fourth refrigeration in the temperature of 3 5 5, until the end of the fourth refrigeration in mid to late September, and use the silkworm in late autumn after the green promotion.

Silkworm babies start eating within 40 minutes of birth, so be sure to sprinkle mulberry leaves on the hatching silkworm eggs first, because maybe they will be born in your dreams.

Newborn silkworm babies are very fragile, so choose fresh and young mulberry leaves, and cut them into strips for them to eat.

In addition to the selection of mulberry leaves, we should also pay attention to not having rotten leaves, moldy leaves, the most important thing is not to have diseased insect leaves, otherwise they will be bitten to death by small insects on mulberry leaves, and when picking mulberry leaves, we should also pay attention to whether mulberry leaves have been sprayed with pesticides, which is also very important to the old key.

Newborn silkworm babies you have to find a comfortable home for them, large-scale breeding will need professional silkworm baskets, how is the family silkworm cartons can be, put in a cool place, room temperature can be kept at 28 degrees Celsius, you can cover the lid to prevent mulberry leaf water evaporation, but you must leave air holes on the lid, open it for a few hours for ventilation, bend high can also not cover, try not to move the silkworm box.

Mulberry leaves are dry to be replaced, we can spread the fresh mulberry leaves on the old mulberry leaves, after an hour or two the energetic silkworm baby will climb on the fresh mulberry leaves, and then take out the fresh mulberry leaves, use a brush to move the silkworm on the dried mulberry leaves to the new mulberry leaves, clean up the silkworm box and put it back. The silkworm box can be cleaned once every two days, and it is not necessary to clean it every time it is fed.

Newborn silkworm babies are not allowed to touch water, and if there are dew drops on the picked mulberry leaves, they should be dried with a towel.

If there are dead silkworms found in the silkworm box, it must be cleaned up in time, and the silkworm box must also be disinfected to avoid infection.

From late January to mid-February (about embryonic development to C1 C2 stage), 2 5 refrigerated silkworm seeds were used, and 25 were used to promote green and ** spring silkworms from late April to early May of the following year. From late December to mid-January, the silkworm eggs are refrigerated at a temperature of about 2 5 and used for intermediate temperature sensing about 1 month before planting. <

1. From late January to mid-February (about embryonic development to C1 C2 stage), start to use 2 5 refrigerated silkworm seeds, and use 25 to promote green with 25 out of the warehouse from late April to early May of the following year.

2. From late December to mid-January, the skin source temperature of about 2 5 refrigerated silkworm eggs is used for intermediate temperature sensing about 1 month before planting. Spring silkworm seed with silkworm seeds, about the beginning of March with a temperature of 10 15 for intermediate temperature sensing, when the embryo develops to a critical period to return to the temperature of 2 5 in the socks refrigerated, late April to early May out of the warehouse to promote the use of green ** spring silkworms; The silkworm eggs used by the summer silkworm are in late April, with a temperature of 10 15 in the middle of the temperature, and the embryo develops to a critical period when the ant returns to the temperature of 2 5 in the refrigeration, and in early June, it is out of the warehouse to promote greening, ** summer silkworm use.
