The next morning, I got out of bed early. When I ran to the balcony, I saw that soybeans and black beans would no longer be wrinkled like yesterday, but bulging, like a little fat man, with a little fragrance. After the observation, I changed the water for soybeans and black beans, and then put them back.
After lunch on the third day, my mother said, "Come and see, there are new changes!" " I heard that I ran in a hurry, yeah! Some beans have sprouted. Mom said, "Yaya, let's take some beans to plant!" " I went to grow beans with my mother in high spirits. Mother said, "When planting, that bud will grow up only when it is upward." Then, insert the beans into the soil of the flowerpot.
Today is the fourth day. After lunch, I went to the balcony to see the sprouts. Today's sprouts are really good-looking, and some are like little mice with a big tail; Some are like tadpoles; There are still naked "little fatty". How cute!
Observation Diary on Seed Germination 2 1 1 month 12 It was sunny on Sunday.
At noon today, I found that the soybean has grown small leaves. The leaves are furry, like a small cattail leaf fan, which stand out from the cotyledons. The cotyledons seem to have shrunk and shriveled a lot. I later learned that cotyledons shrink and shriveled because the leaves have grown out. Cotyledons should provide nutrients for the leaves and let the small leaves grow smoothly. I was so happy to see that the soybeans had grown leaves. I quickly took out a ruler and measured it. Boy! It used to be 1 cm, but now it's almost 16 cm. I gently stroked it and thought, Soybean, grow up quickly. I will watch you and grow up with you.
After a few days' observation, I consulted a lot of information about seeds through the computer. I know that seed germination is that radicles first emerge from cotyledons, grow into roots, then cotyledons open, and then sprout. The cotyledons of some seeds do not store much nutrients, so they have to carry out photosynthesis after being unearthed to make nutrients for the early growth of plants.

As soon as school was over, I soaked the mung beans given to me by my teacher in water for several hours. The mung beans were full of water, round and full, and they were about to burst, but some of them were small, like malnourished children. I found a paper cup, poked a few holes with a toothpick, spread a soaked napkin on it, and then put a towel on the top of the cup, so that Baby Bean can breathe fresh air.
It will be sunny on Friday, July 8.
I can't wait to see mung beans early this morning. Some have sprouted buds of about 2 cm; Some took off their green coats, revealing white naked bodies; Some have just cracked a small crack! They are all anxious to go to the outside world to see how splendid it is!
On July 10, it was cloudy.
Today I went to see mung beans again. Seeing that mung beans are scrambling to grow up, some of them are already very big, about 10 cm long. Like a weightlifter, they all lift the gauze, which is really a great man. Some of them grow two young leaves, like a pair of scissors, and some green sprouts are intertwined with each other. It seems that pairs of close friends are talking quietly! There are several green shoots that grow the shortest. They hang their heads as if they were afraid of being laughed at by their peers. How interesting!
Through this observation, I have gained a lot of knowledge and realized the joy of life.
Observation Diary on Seed Germination 4 Sunny day in 20xx year, month and day
This morning, I found that soybean seeds have grown small roots. That's what the teacher did for us. When the teacher gave it to us, it was still a small soybean with a diameter less than 1 cm, flat and flat, and now it has grown very short roots and almost invisible fibrous roots.
Some soybeans have taken off their clothes, and some soybeans are taking off their clothes. The peeled soybean seeds are like a small green balloon. The root of a seed is segmented, and there are several small protruding corners on the edge of the root, which is its fibrous root; Its cotyledons are like a flat feather bat, green, with some luster, and it is very quiet whether it is close or far away. The germination period of soybean may make you unexpected. Generally, the germination of seeds takes1-2 weeks, while the seeds of soybean, as long as they are suitable for growth, are 4-5 days long and only1-2 days short.
I put the seeds of soybeans in the living room, which not only facilitates my observation, but also adds a little green to my home. No wonder our whole family likes it!
Today, the 120 seeds I planted originally germinated. At that time, I used 60 soybean seeds and 60 mung bean seeds.
I'll use two pots first, one for soybeans and the other for mung beans. I put a little soil in the basin where I am going to plant soybeans, pressed these 60 soybean seeds on it one by one, and covered it with several layers of soil. Then water it. With the experience of planting soybeans, 60 mung beans were planted.
I come to water every day. After a week, some soybeans and mung beans drill out green spots. After another week, these soybeans and mung beans grow a little taller. I have been watering them, and now they are several centimeters high.
I think we can find a germination rate. Germination rate = number of germinated seeds/total number of seeds * 100%. Then, for these two kinds of seeds, I ask for their germination rates.
Germination rate of soybean: 60 seeds have been planted and 36 seeds have germinated.
The germination rate of soybean = 36/60 *100%
＝3/5* 100%
＝60%
Germination rate of mung beans: 60 seeds have been planted and 24 seeds have germinated.
Germination rate of mung bean = 24/60 *100%
＝4/ 10* 100%
＝40%
Look, I also made a list:
Total number of seeds (grains) in category test Germination rate of seeds (grains) Soybean 603660% Mung bean 602440%
There is mathematics in life. Light up your eyes and you will find many problems in mathematics.
Diary of Observation on Seed Germination 6 Sunny day in 20xx year, month and day
No water! I quickly watered the water, but it was too late ~ ~ One bean sprout died, and another bean sprout survived fortunately. It turns out that watering is also a task! The next day I saw that the bean sprouts were two centimeters long! I am delighted to see the results of my careful cultivation, not to mention how happy I am!
Wow! Don't look, don't know, look at the next jump! My bean sprouts have grown green leaves, of course! Bud stems have grown a lot, too. Measure them. They are already seven centimeters high! Ha ha ha ha! The cultivation results of my "Cheng Botanist" are good!
A few days later, my mung bean sprouts grew more leaves, green and green, which made me jump three feet high and dance.
I put bean sprouts in a cup with a little water. My father said that if you put a little water, it will grow. Two days passed, and the bean sprouts really grew luxuriantly, but the water was much less. There are some buds on the leaves of my bean sprouts. Maybe they are going to grow leaves again. Finally, I filled the cup with water, so let them grow happily!
One hot summer afternoon, I ate iced watermelon and felt really cool. My mother told me that when she was a child, she often threw watermelon seeds into flowerpots, and green seedlings would grow in a few days. I found it interesting and planned to give it a try.
Wednesday, August 18 is cloudy.
I found a flowerpot with half a pot of soil, dug several small holes, put the washed watermelon seeds in it, covered it with a thin layer of soil, and watered the baby seeds with some water. I put the flowerpot in the shade of the balcony and thought to myself: Baby watermelon will sprout quickly.
Saturday, August 2 1 Sunday, cloudy with showers.
Three days later, a watermelon seed germinated, and a little green bud emerged from its dark shell. It cocked its head as if to say happily: Hello, little master, I'm the watermelon baby you took good care of.
Thundershower on Tuesday, August 24th.
Early this morning, I couldn't wait to see the baby watermelon seeds. I found that several watermelon seeds were sticking out of their heads, and the one that germinated the earliest was the tallest, and two small green buds were closed. Through this watermelon seed germination, I realized that seeds don't need sunshine before germination, but need proper temperature and humidity. My mother said that when all watermelon seeds grow green seedlings, they can bask in the sun. The mystery of science is really amazing.
Observation diary about seed germination 8 Today, my mother planted the seeds of Lentinus edodes in the flower bed of the yard. The seeds of Lentinus edodes are black, oval in shape and look like small sesame seeds.
Monday, September 24th will be fine.
I ran out early this morning to see if the mushroom dish had sprouted. I didn't expect the mushroom dish to be like a sleepy child, hiding in the arms of my mother.
Tuesday, September 25th will be fine.
Today, I saw many small buds in the flower bed, so I watered them a little. Their roots are white and transparent, and there are two small yellow leaves on the roots. They are closely together like a pair of brothers and sisters who will never be separated.
Wednesday, September 26th, cloudy.
I was particularly happy this morning, because the leaves of my mushroom dish turned green, and my son was divided into two halves and became a caring type.
It rained on Thursday, September 27th.
It's raining cats and dogs today. At school, I was uneasy and thought: Will the seedlings be all right? When I came home at night, I found that the seedlings were fine and many leaves were growing.
......
I like my mushroom dish!
