Write a record of the growth of the plant, a record of the growth of the plant

Writing ideas:You can write a record of the growth of bean sprouts and garlic seedlings, and plant them at home so that you can observe the records, check what kind of changes the plants have every day, and then record them fluently and clearly.

Today, Mr. Wu brought an automatic bean sprouts machine, and the students' eyes were staring at the machine. Then Mr. Wu gave us a few mung beans, a paper towel and a plastic cup. The mung beans were slippery to the touch, slippery like a frozen lake, round like a leather ball.

I want my little one to grow up quickly.

What happens when mung beans are soaked in water? It turns out that some mung beans are soaked in the water like a hot spring; Some stayed in the water and stripped off their new green clothes; Some of the mung beans cracked, as if they had been split with a large knife; Some of them are like using a powerful pump to get enough gas, and the chubby look is very cute; Some shy green beans never come out.

When I looked at the mung beans, I found that they had all sprouted, 5 mm long, and looked like the little black tail of a miniature tadpole. And Mr. Wu's mung beans seemed to have been enchanted overnight, and they grew up like they were 2 centimeters long, and they all sprouted. Mr. Wu's mung bean sprouts.

That's amazing, but it's four times as big as ours! What an astonishment! The sprouts crawl on the ground like a worm; Swim like a tadpole in the water...

On Monday morning, I happily went to school with my bean sprouts in my hand, thinking: my bean sprouts should be much taller than my teacher Wu! Happily daydreaming along the way.

When I arrived in the classroom, I was disappointed to see Mr. Wu's ancient bean sprouts. Mr. Wu gave us some bean sprouts from the bean sprouts machine, and I was comforted. We asked

Why? Mr. Wu said: "The growth of bean sprouts is closely related to temperature and humidity.

I used my bean sprouts to compare with my teacher, and I couldn't compare at all, but Mr. Wu was twice as long as me.

After class, the students still stared intently at the bean sprouts machine. There was a glint of hope in his eyes, as if he had a new plan for cultivating bean sprouts.

Record the growth process of impatiens.

Impatiens du, also known as henna, zhi

It is an annual herbaceous flower of the impatiens flower family. Impatiens love sunlight, are afraid of moisture, are heat-resistant but not cold-resistant, are suitable for growing in loose and fertile slightly acidic soil, have strong survivability, good adaptability, and generally have few pests and diseases.

On the first day, I selected 10 fuller seeds and planted them in a pot, and inserted toothpicks according to the teacher's instructions. The rest was scattered in the flower beds downstairs. Ever since the seeds were planted, I have been anxiously waiting for them to grow every day.

On the 7th day, it began to sprout, arching out of the soil, breaking the shell and sprouting, like wearing a small hat.

x On the 14th day, today is a happy day, I finally saw the impatiens I planted growing out of the soil. There are large and small, the large stem is 2 cm long, the stem is very thin, there are two ** leaves, round, and the leaf surface and edge are mostly light. My father and I transplanted them into larger pots and buried them 1 cm deep under the soil, with a spacing of 5 cm between the plants, so that they would have more nutrients and sunlight.

On the 21st day, I chose one and measured it with a ruler, the stem was 4 cm high and about 1 mm thick, and two true leaves grew at the top of the stem, and the edges of the leaves were jagged.

On the 29th day, it grew a lot, and there were 4 large true leaves on the plant, and 2 small leaves were still growing.

On the 35th day, I found that the growth of leaves has its own rules, two leaves grow cross-growing up and down, and the top and bottom of each leaf basically do not overlap together.

On the 50th day, there are many leaves, the stem is 15 cm high, and the stem thickness is about 3 mm.

Target number: time, plant height, number of leaves (number of branches).

Subjective quantity: source development period (buds, seedlings, etc.), plant color, growth condition, soil condition (whether there are insects, whether there is odor, whether there is hardening, etc.).

If this is a biological study, it can be measured to determine: photosynthesis.

Effect yield (by releasing oxygen, or reducing carbon dioxide.)

respiratory consumption (through the release of carbon dioxide), etc.

Objective quantity: time plant height number of leaves (number of branches).

Subjective quantity: development stage (buds, seedlings, etc.) plant color growth condition soil condition (whether there are insects, whether there is peculiar smell, whether it is compacted, etc.).

In the case of biological studies, it can be measured: photosynthesis production (through oxygen release, or carbon dioxide reduction), respiration consumption (through carbon dioxide release), etc.

Palm I have a strange plant in my house, and it's named.

It is to record the changes in the growth of garlic seedlings in 15 days, such as the height change of garlic seedlings every day.

1-15 days of growth process record.

1) On the 1st to 3rd day, the growth rate of garlic seedlings is relatively slow, and young shoots have not grown.

2) On the 4th day, the height of the garlic sprouts is about 1 cm.

3) On the 6th day, the height of the garlic sprouts is about 3 cm.

4) On the 8th day, the height of the garlic seedlings is about 5 cm.

5) On the 10th day, the height of the garlic seedlings is about 13 cm.

6) On the 12th day, the height of the garlic seedlings is about 20 cm.

7) On the 14th day, the height of the garlic sprouts is about 24 cm.

8) On the 16th day, the height of the garlic seedlings is about 28 cm.

9) On the 18th day, the height of the garlic seedlings is about 32 cm.

Tips for sowing garlic seedlingsWhen sowing garlic seedlings, it is best to choose plump and round seeds, and the sowing soil can be mixed with humus, garden soil, and river sand, and the seeds can be buried in one-third of the soil when sowing. After sowing, it is best to place the garlic seedlings in a semi-shaded and ventilated place indoors.

During the planting period, it is necessary to properly water the soil, wet the soil every time you water, try not to leave stagnant water, usually planted properly, garlic seedlings will germinate in 7 15 days, and you can grow seedlings after 1 month. In the later stage of planting, the plants should be watered and fertilized in time, and the plants should be pruned regularly during planting.
