1. Can you make money by raising silkworms? Please give an example!

The price of silkworm cocoons often fluctuates. When it is high, you can make a lot of money. When it is not, you may lose money. No matter whether you make money or lose money, one thing is certain, that is, raising silkworms is very hard work. You have to work day and night. Whether it is sunny or rainy, you have to pick mulberry leaves to feed them. There are many diseases. People who don’t have certain skills should consider it carefully. For reference.

2. How much land is needed to raise a bed of silkworms? How many mulberry leaves can be harvested from one acre of mulberry land in a year? How many beds of silkworms can be raised in an area of ​​160 square meters?

It is about the same size as a 32K paper. After the third instar, it needs to occupy a room of about 30 square meters. 160 square meters divided by 30 equals 853 sheets. A 160 square meter area can support about 853 silkworms.

Counting from the top of the mulberry branch downwards, the 2nd-3rd leaves are used for ants; the 3rd-4th leaves are used for 1st-instar silkworms; the 4th-5th leaves are used for 2nd-instar silkworms; the 5th-8th leaves are used for 3rd-instar silkworms; and the leaves are collected from the lower part of the mulberry branch upwards from the 4th-instar silkworms. The mulberry leaves for silkworms of each instar must be fresh and tender. 70% of the leaves used for the whole day should be collected in the morning when the dew has just dried, and the remaining 30% should be collected in the evening when dew drops can be seen on the leaf tips. The mulberry leaves should be transported immediately after being collected to prevent them from withering.

Things to note when raising silkworms:

1. Silkworms cannot die of starvation; they will only die if they get sick.

2. Do not touch the silkworms with your hands; wash the mulberry leaves you feed them, but be sure to wipe off the water after washing. Do not let the silkworms touch the water, otherwise they will die. Put them in a paper box or a small sieve for sifting rice. If you use a sieve, put some paper pads at the bottom of the sieve.

3. Silkworms are particularly sensitive to fragrance, so perfume, mosquito coils, air purifiers, scented cosmetics, etc. are not allowed. Any type of pesticide is absolutely prohibited.

4. When the silkworms just hatch from the eggs, you need to be especially careful with them. Feed them with relatively tender mulberry leaves. When changing mulberry leaves, use a very soft brush to move them. Be careful with the force. Sometimes the mulberry leaves are too dry, and if you are not careful, the silkworms will be left on the discarded mulberry leaves during the process of changing mulberry leaves. It is a little difficult to raise them when they are young, but it will be easier when they grow up. When they are about to make cocoons, use some wheat straw to tie them into branches.

The breeding of late autumn silkworms generally lasts from early to mid-September to early to mid-October. Although the breeding time is short, the economic benefits are still good as long as proper measures are taken.

1. Strictly disinfect and control the harm of silkworm diseases. Clean the silkworm room half a month before raising late autumn silkworms, and wash and dry the silkworm tools. Scrape off the topsoil from the floor of the silkworm room and fill it with a new layer of soil, and paint the walls with 20% lime slurry; sprinkle the floor, walls and silkworm tools of the silkworm room with clarified bleach containing 1% effective chlorine, close the doors and windows to keep it moist, and let it dry in the shade. During the breeding process, use bleach containing 0.3% effective chlorine. During the young silkworm stage, use a new towel to dip in clarified liquid and gently wipe both sides of the mulberry leaves before feeding. During the adult silkworm stage, wet the leaves with clarified liquid at noon on a sunny day and feed them to prevent the silkworms from eating pathogens; use anti-rigidity powder once for ant silkworms and silkworms of various ages and silkworms in the prime feeding period to prevent the occurrence of rigor mortis; starting from the 3rd age, add 500 mg/L of chloramphenicol to the silkworms every other day to prevent bacterial and viral diseases; after each sand removal, spray the ground and walls with bleach containing 1% effective chlorine to prevent the spread of silkworm diseases.

Second, adjust the climate and improve the breeding environment. First, adjust the indoor temperature and humidity. The temperature of 1-2-year-old silkworms should be maintained at 27-28℃, and the relative humidity should be maintained at 85-90%. After each additional age, the temperature drops by 1℃ and the humidity drops by 5%. When the silkworms reach the 5th age, the temperature should be maintained at 24-25℃ and the relative humidity should be maintained at 70%. Second, pay attention to the ventilation of the silkworm room. Especially during the adult silkworm period, pay more attention to the ventilation of the silkworm room.

3. Careful feeding to enhance the physique of silkworms

1. Collect the ants at the right time: After getting the silkworm eggs back, pour them out immediately and spread them flat in a silkworm winnowing machine with paper padding. Cover the winnowing machine to block out the light. Open the cover at dawn the next day to allow the silkworm eggs to hatch due to light. When a large number of ants and silkworms hatch, collect them (it is best to collect them before 8 am). After disinfecting the ant bodies, you can feed them with mulberry leaves.

2. Select and pick leaves: Count from the top of the mulberry branch downwards, use the 2nd-3rd leaves for ants; the 3rd-4th leaves for 1st-year silkworms; the 4th-5th leaves for 2nd-year silkworms; the 5th-8th leaves for 3rd-year silkworms; and start picking leaves from the bottom of the mulberry branch upwards for 4th-year silkworms. The mulberry leaves for each age should be fresh and tender. Pick 70% of the leaves for the whole day in the morning when the dew has just dried, and the remaining 30% in the evening when dew drops are slightly visible on the leaf tips. Transport the leaves as you pick them to prevent them from withering.

3. Feed mulberry leaves frequently: When raising late autumn silkworms, you should increase the number of times you feed them mulberry leaves and reduce the amount of mulberry leaves you feed them each time. In particular, you should feed them mulberry leaves at least 6 times a day and night during the growing period. The key to feeding mulberry leaves is during the period of reduced feeding and the period of full feeding. Since late autumn silkworms sleep quickly, if you do not feed them mulberry leaves during the period of reduced feeding, some silkworms will starve and sleep. When the silkworms are about to sleep, in addition to using fresh and tender leaves, you should add floating leaves before sleep in the first two sleeps. When they are about to sleep, you should feed them a thin layer of leaves after they have eaten 2/3 of the food to ensure that they sleep well.

4. Remove silkworm feces frequently: generally, remove it once before the first instar silkworms go to sleep; once each time when the silkworms are woken up and before they go to sleep in the second instar silkworms; once each time when the silkworms are woken up, during feeding, and before they go to sleep in the third instar silkworms; the silkworms of the fourth and fifth instar silkworms must be removed once a day. If it is rainy during the fifth instar silkworm period, it is best to remove it twice a day.

4. Prevent rats and flies to ensure the number of silkworms. During the silkworm rearing period, measures such as raising cats and placing medicines should be taken to prevent rats from eating silkworms. Myiasis is a common disease of late autumn silkworms and should be prevented and treated. First, spray 500 times of silkworm fly killing aqueous solution evenly on mulberry leaves, add food once during the peak feeding period of the 4th instar, and add food every other day from the second day of the 5th instar; second, wash the bright silkworms in 300 times of silkworm fly killing aqueous solution before putting them on the cocoon.

5. Reasonable cocooning to improve the quality of cocoons. The silkworms cocooned should be mature silkworms, with translucent chest, slightly yellowish abdomen, and 2-3 feces visible at the tail anus. When cocooning, lightly catch and lower the silkworms, and 120-150 mature silkworms per meter of cage are suitable. The cocoons of late autumn silkworms can be harvested 7 days after cocooning.

3. Was raising silkworms profitable in the 1980s?

It's quite profitable.

Silkworm cocoon breeding is divided into spring silkworms, dormant silkworms, and autumn silkworms. Autumn silkworms are divided into mid-autumn silkworms and late autumn silkworms. Spring silkworms have the best quality, followed by autumn silkworms. Breeding varieties include Nongsang, Greater China, etc. The growth cycle of silkworm cocoons is limited by temperature. Spring silkworms are bred around April 20th every spring, with a growth cycle of 26-27 days. Summer cutting begins around May 20th. After the mulberry tree grows new leaves again, dormant silkworms are bred around June 25th, with a growth cycle of 24-25 days. Because the interval between mid-autumn silkworms and dormant silkworms is short, it is feared that poor disinfection will affect growth and quality. Mid-autumn silkworms and late autumn silkworms are generally not raised. Due to factors such as temperature, environment, and purchase price, some breeders choose spring and autumn silkworms, while some breeders choose three seasons.
