What do we have to give the silkworm to eat, what can the freshly molted silkworm eat

When the silkworm has just hatched from the egg, you should be especially careful with it, feed it with a relatively tender mulberry, and use a very soft brush to move it when changing mulberry leaves, and pay attention to the strength; Sometimes the mulberry leaves are too dry, and if you are not careful, you will leave the silkworms on the mulberry leaves to be discarded in the process of changing the mulberry. When you are young, it is difficult to raise a little, but it is easier to do when you grow up. When it is about to form cocoons, take some wheat stalks and tie them into the shape of branches.

After breaking out of the cocoon, put them together in a box, they will mate together, and then spawn and spawn to help the bones and blast. Sometimes because there are few silkworms raised, the moths will be left alone when the cocoon is broken, but don't worry, as long as a pair of silkworms is successful, I believe it will be enough for you to raise.

Silkworm babies eat a lot of mulberry, so they grow very quickly and their body color gradually fades. However, its appetite gradually decreases and even fasts completely, it spits out a small amount of silk, fixes its gastropods on the silkworm seat, raises its head and thorax, and no longer moves, as if it is asleep, which is called "sleep". The sleeping silkworm seems to be stationary on the outside, but the body is preparing to shed its skin, and after taking off the old skin, the growth of the silkworm will enter a new age stage, from the ant silkworm to the silkworm cocoon a total of 4 times.

Sleeping is one of the growth characteristics of silkworms, and sleep is a genetic trait of silkworms, which is also affected by the environment. At present, the silkworms raised in China are four-sleeping varieties.

When the silkworm baby reaches the end of the fifth instar, it gradually shows the characteristics of old maturity: first, the excreted feces change from hard to soft, from dark green to leaf green; loss of appetite and decreased amount of mulberry eaten; The anterior digestive canal is empty, and the thorax is hyaline; Then stop eating completely, the body drive is shortened, the abdomen also tends to be transparent, the cephalothorax of the silkworm body is raised, the mouth is spit silk, and the left and right swing up and down to find a place to camp in the cocoon, such a silkworm is called a mature silkworm.

The silkworm baby is dormant. Generally, it takes 4 times of dormancy before forming a cocoon.

The larvae that have gone dormant once are called the second instar larvae, and the larvae that have gone dormant twice are called the third instar larvae, and they only begin to spin silk and form cocoons after a few days after becoming the fifth instar larvae.

Mainly eat mulberry leaves, but you can also eat some lettuce leaves, elm leaves, dandelions. These are all foods that silkworms love to eat.

Silkworms love to eat mulberry leaves, cabbage leaves, or other vegetable leaves, so when raising silkworms, you should prepare enough food.

I love to eat mulberry leaves, and everyone knows that silkworms are mainly mulberry leaves, so I usually like to put some mulberry leaves when raising silkworms.

I like to eat mulberry leaves, which are a very delicious food for silkworms and can also improve their nutrition.

Mulberry leaf. If silkworms are fed with this thing, they can grow up quickly, and the mortality rate is also very low.

This small animal usually prefers lettuce leaves, as well as dandelion, lettuce leaves, and elm leaves.

Silkworms love to eat mulberry leaves, mulberry leaves are the favorite food of silkworms, silkworms are particularly energy and time, is a relatively difficult job.

Silkworms love to eat mulberry leaves, lettuce leaves, dandelions, belong to vegetarian animals, and the process of raising silkworms is very hard.

Of course, their favorite food is mulberry leaves, and it may be their only favorite food.

Silkworms mainly feed on leaves, but different types of silkworms eat different foods. Mulberry silkworms like to eat mulberry leaves, tussah silkworms and silkworms love to eat sharp leaves, and amber silkworms can eat evergreen leaves such as nanmu leaves and tiger thorns.

Mulberry leaves are the most suitable natural food for silkworms to eat, and they are also the most common food eaten by silkworms. However, in addition to mulberry leaves, silkworms can also eat lettuce leaves, elm leaves, dandelions, lettuce leaves, etc.

In fact, silkworms can be divided into many types such as mulberry silkworms, tussah silkworms, sky silkworms and amber silkworms, and the food eaten by different types of silkworms is also different.

Mulberry silkworms like to eat mulberry leaves, and also eat lettuce leaves and lettuce leaves. Silkworms feed on the leaves of plants such as Quercus japonica, Quercus mongolica, Mistletoe, Artemisia willow, pear, apple, etc.

The silkworm mainly feeds on the leaves of Liaodong oak, Mongolian oak, tethered oak, and sharp oak, while the amber silkworm feeds on the leaves of Nanmu, and also eats the leaves of evergreen trees such as tiger thorns.

Silkworms are born without necessarily having to eat mulberry leaves, so far, silkworms can eat no less than 20 kinds of leaves, such as dandelion, elm leaves, lettuce leaves, lettuce leaves and so on. But it is not easy to eat more, these can be used in an emergency, and it is best to use mulberry leaves.

How to raise silkworms.

1. Small silkworm leaf standing sports.

It is a new technology successfully researched by the Sericulture Research Institute of the Chinese Academy of Agricultural Sciences. It has changed the habit of flat feeding for thousands of years, using leaves to wear into a string, hang vertically, stand upright for mulberry, silkworms climb to feed, and silkworm dung falls naturally. According to the survey, the use of this technology can save mulberry leaves 33, the average seed saving leaves, increase the yield of silkworm cocoons, save labor, and save 75 silkworm seat area.

2. Small silkworm plane 2 back breeding.

1) Cover with snakeskin cloth, to adapt to the times, flexible mastery, 1 2 years old upper cover and lower pad.

2) Select suitable mature leaves, cut mulberry can be larger, and grasp a reasonable amount of mulberry.

3) Expand the seat in advance and remove sand in time.

4) In view of the fact that the coverage is easy to increase the humidity of the silkworm seat and the disease is easy to multiply by microorganisms, it is necessary to strengthen the epidemic prevention and sanitation work.

The 4th year old adopts "leaky air and breathable education".

The technology is a new technology that the Chinese Academy of Agricultural Sciences and other units have successfully cooperated in researching, it is the use of plastic folding, wavy folding, moderate branch holes and stretching characteristics, paved into a leaky and breathable silkworm seat, supplemented by the anti-drying measures of the following pad covered with snakeskin cloth, to achieve the purpose of 3 4 instar silkworms to give a day. Because the leaves are on the cluster, the silkworm is in the cluster, and the manure is under the cluster, the pollution of mulberry eating is reduced, and the silkworm is healthy and disease-free. The technology can save 40 labor, save 50 silkworm seat area, save mulberry leaves 20.

The small silkworm sports can be matched with this method to organize 1 4 years old co-breeding or centralized feeding, so that 80 silkworm farmers will focus on the main energy of silkworm raising in the last week, so as to achieve "five years old and one week silkworm raising".
