Sericulture composition

In life, work and study, everyone has been exposed to composition. According to different genres, composition can be divided into narrative, expository, practical and argumentative. There are many points for attention in composition. Are you sure you can write? The following are my collected essays on sericulture for your reference, hoping to help friends in need.

One day, my father bought me a box of small silkworms.

Opening the box, I saw small silkworms in all directions, and black water silkworms were crawling slowly. Ah, it's so cute! You see, they crawl freely, like big bosses. One of the little silkworms held her head high, as if to say, "I am the owner here, and my home is very big!" " "I touched the mulberry leaf next to it. It was dry. I quickly took mulberry leaves out of the refrigerator. It suddenly occurred to me that the science teacher said that the mulberry leaves just taken out of the refrigerator had dew, and silkworms would have diarrhea after eating them.

So, I first wiped the mulberry leaves with paper, and then gave them to my ants. Delicious, delicious, delicious, haha, this is my snack, and they eat it with relish!

A few days later, I found that my silkworm was very different from before. They have skinned these days, and they have changed from "little black" to "little white"!

Ah, I am so happy to watch these lively little silkworms grow up slowly!

Silkworm rearing composition 2 My little silkworm has cocooned!

Early in the morning, when I went to see the silkworm baby after breakfast, the box couldn't be opened, as if it was stuck by something. What happened? I looked in curiously through the tiny gap in the box, but I saw a large piece of white silk covering the box. It turned out that it was silk that stuck the box and lid tightly. Fortunately, there are straws that grandma has already prepared in the box, and I don't know when there are a few round "eggs" between straws. It should be cocoon. Silkworm babies hide in cocoons and wrap themselves up.

So my worry began: isn't the greedy silkworm baby hungry in the cocoon? You won't suffocate, will you But then I thought: this is the packaging of silkworm baby, absolutely no problem. I picked up the box and showed it to grandpa. Grandpa gave me a thumbs-up and praised my skill in sericulture! I was flattered by my grandfather's praise and thought, "Needless to say, I am really good at taking care of silkworm babies."

Don't you know that our classmate's silkworm baby has cocooned? I have to talk to them and see who can take care of the silkworm baby best.

Composition 3 On watching others raise silkworms before raising silkworms, I found it very interesting and decided to raise silkworms myself. After learning about sericulture from my father, I slowly began to raise silkworms. First, I found mulberry leaves and lettuce leaves, then I found silkworm eggs and put them in a small iron box. I drilled holes in the small iron box for ventilation, put some cotton in the box, put the box on my body during the day and put it under the bed at night. After 10 days of incubation, the silkworm baby finally hatched. I quickly opened the box and looked at it, then put it in the box. I am very happy to see the silkworm baby grow fat from a very young age. It wears a white coat and its head is arched.

Adults say that silkworms grow up and silk can be made into many precious things. Since ancient times, there have been many poems praising silkworms. As we all know, as the saying goes, "When the silkworm dies, the night candle tears", the silkworm dedicates all the essence of its body to people to repay their gratitude, which is what all of us should do.

Last spring, my grandmother bought me some small silkworms. Silkworms are very cute, but the biggest problem is that there are no mulberry leaves at home. My father picked many mulberry leaves to support my sericulture.

Every day when I come home from school, I can't wait to send delicious food to the silkworm babies. They ate with relish and my heart was filled with joy.

Among these silkworms, my favorite is a black-and-white tiger-spotted silkworm. It has a good appetite. It keeps eating and eating. Other little silkworms are "going up the mountain", and it is still eating and eating there ... One day when I came home from school, I found it suddenly died. I am sad, but I also wonder why it died. Will it be eaten to death?

In the process of sericulture, there is happiness when you are sad. Soon, the young silkworms turned into moths, came out of their "small houses" and laid many eggs. My mother helps me keep my eggs in the refrigerator.

This year is spring. We took the silkworm eggs out of the refrigerator and put them in a shoe box to bask in the sun. After waiting for many days, the silkworm finally came out. They are black and small, completely different from the "white fat" silkworms I raised last year. Haha, I'm going to start "Silkworm Keeping" in the new year.

Composition of Silkworm Raising 5 My four young silkworms finally got cocoons, and one of them was white in Huang San, which was very beautiful and aroused my great curiosity.

At noon, as soon as I finished eating, I couldn't wait to get ready to break the cocoon with scissors. I want to see what's inside. I took out the yellow cocoon with the longest cocoon forming time and gently cut off the silk with scissors. Next, I didn't dare to make a move, because I was afraid of cutting it to death, so I carefully drew a mark on the cocoon, cut off the silk on the mark, and finally gently cut the cocoon in half. Then I was surprised to find a pupa in it. Pupa is oval, bigger than silkworm, and can't walk. I don't know what to do. Like silkworms, pupae are divided into head, chest and abdomen. Only when you touch it will it move, as if to say, "What are you doing? Don't disturb my sleep. "

Silk can be made into silk, clothes and many beautiful handicrafts. Silkworms are helpful to us. Everyone should take good care of them and never hurt them.

On Friday, I bought some silkworms in the supermarket. As soon as I got home, I opened the box and built a nest for the silkworm baby. Silkworm babies are all dark, small and exquisite, only two millimeters long!

When I got home, the silkworm babies looked at me as if to say, "I'm starving!" " "I woke up immediately, picked some mulberry leaves and put them in the box. However, silkworm babies don't eat, and I secretly scold them for being "picky eaters". At this time, I suddenly remembered what the science teacher said-I have to cut mulberry leaves into strips before silkworms can eat them. I immediately found scissors, cut mulberry leaves into "filaments" and put them in. That's a clever trick. Silkworm babies are scrambling to eat!

Get up the next day and go to "measure the height" of the silkworm babies. Silkworm babies have grown by a millimeter, and the biggest one has grown by two millimeters! After cleaning the "nest" for the silkworm babies, I gave them a "mulberry leaf feast". Afraid that the silkworm babies are too fat, pick mulberry fruits for them to play with and let them exercise.

I really hope that the silkworm babies can grow up quickly!

Composition 7 About Silkworm Breeding Today, many people gathered around. I took a closer look and found that the teacher sent silkworms again. I wanted to keep them, so I went over and asked the teacher to bring me some.

More than a dozen mulberry leaves were put in the evening, and the next morning, there were holes in them. These little silkworms are growing up slowly. The residue will peel off during the growth process, and once peeled off, it will grow for a period of time. Grow up and eat more. During the half hour I watched them, their mouths never stopped. I found a good mulberry leaf. Let's get to work. My mouth clicks from right to left ... I can't stop eating.

Because of eating, mulberry leaves are green, the head is green, and yellow-green will appear on the chubby body. In the process of their growth, not only their body shape will change, but also their appetite and poop will change. When they first came out of seeds, their poop was smaller than a grain of sand, but when they grow up, their poop will be as big as soybeans.

Composition of sericulture 8 In a science class in March this year, the teacher asked, "Who is interested in sericulture?" I raised my hand without hesitation. After a long wait, the silkworm finally came. At first, the baby silkworm was very small, just like a caterpillar. It has a small mouth and many tiny legs. It crawls slowly by crawling of its body. Silkworm's body is round and soft, and it feels as if it has no bones. Silkworm is a very hardworking guy. I seldom see them resting. They chew mulberry leaves every minute of the day. Silkworm babies grow very fast. After only two or three weeks, they became big and fat silkworms. Suddenly one day, I found that the silkworm didn't want to eat mulberry leaves. They supported themselves with the second half of their bodies, their heads and upper bodies standing upright, as if looking for something. Then, I found that their mouths spit out thin silk, one or two. Countless silk wrapped it slowly until it was wrapped in silk until it was out of sight. Cocoon is like an oval egg. Cocoons will turn into moths in two or three weeks. A moth has two big wings. Its body is like a silkworm when it was a child. There is something black in its eyes, which seems to be our eyebrows. The eggs laid by moths are divided into three colors: yellow, red and black. This is my experience in sericulture.

Sericulture composition 9 These days, I have raised several silkworm babies. Every day, I get up early and feed the silkworm babies with mulberry leaves. Listen carefully, and I will hear the rustling sound when the silkworm baby eats mulberry leaves, as if thanking me.

Under my careful care, the silkworm baby grows up day by day.

One morning, I went to feed mulberry leaves to the silkworm baby as usual and found a piece of silk in the box where the silkworm baby was raised. I was curious, so I asked my father. My father smiled and said to me, "Silkworm babies are spinning silk and are going to make cocoons."

When I came home from school, I couldn't wait to see the silkworm baby, but the silkworm baby was gone and I only saw the cocoon. It turns out that the silkworm baby tied herself up. Dad told me that the textile workers processed these cocoons into the clothes we are wearing now.

The dedication of the silkworm baby is really great. It is really "the spring silkworm must weave until it dies"!

Today, I have been raising silkworms for six days. My mother brought back another box. I opened it, and there were some mulberry leaves in it, and there was a bag of silkworm eggs in the corner of the box. When I look carefully, it is not a package of silkworm eggs, but a cocoon with a layer of silk on the surface and another layer of silkworm eggs. I gently tore off the layer of silkworm eggs and peeled off the cocoon. I went to see another box. A big silkworm kept crawling, holding its head high, as if to say, "I am the king of silkworm, I am the king of silkworm."

A few days later, I found that there were always dead silkworms, and several died, from thirteen to seven, a total of six died. I am sad.

After a few days, I finally figured it out, because-mulberry leaves are pesticides.

At dinner today, my father suddenly said, "Xuan Ming, dare you touch the silkworm baby in your hand?" I said, "Ah! Not good, especially bad, very bad! " So the father asked his brother to touch the silkworm baby. My brother tried to touch it with his eyes closed. Suddenly he said, "Wow, it itches!" "When I heard this, I felt even more scared. Dad encouraged me to say, "It's okay, don't be afraid. "

So I closed my eyes and got up the courage to say to my father, "Come on!" "Dad put the silkworm baby in my hand, and I screamed and almost cried. After a while, there was a cold feeling in my palm. Silkworm baby is crawling gently, cold and soft, and has a little itchy feeling. What a lovely silkworm baby, it is looking up and smiling at me. Father, mother and brother all laughed, and so did I.

Actually, the silkworm baby is not so terrible. I like this feeling.
