Holly observation diary 100 words

Holly's observation diary 100 words, observation diary (Holly) 300 words. What shape are its leaves? What is the difference between its branches? Will you get sick?

After dinner today, my grandfather and I observed them in Xing Li, Shui Xin.

I found three kinds of holly: the big one is about two meters high; Among them, there are about one meter two; Less than one meter.

Generally, Ilex macrophylla is used as an ornamental plant; Small and medium-sized holly is used as a barrier.

I collected 12 different types of Hollyleaf samples: two medium-sized samples; The younger one took five copies, and the older one took five copies.

I found that holly leaves have long needles; There are slightly longer ones called long ellipses; There are also oval, round and even diamond-shaped ones. In addition, the leaves of holly are different in size and thickness, different in depth, and some have thorns! Some leaves are smooth, others are curly. ...

I also found that the branches of Holly are green and brown, and some branches have uneven tumors. ...

I also found that there is a medium-sized holly that is particularly afraid of illness without thorns, and many leaves have withered. Last year, I saw this holly being uprooted in large quantities. I didn't expect holly, a vital plant, to get sick and die!

I have roughly investigated ten quarantine areas, nine of which are small holly. Perhaps the weak disease resistance is the reason why the medium-sized Ilex is eliminated.

Grandpa said, "Our investigation is still careless, unscientific and incomplete."

Alas! Nature is really mysterious!

It is too difficult to observe Holly's observation diary 400 this month.

Who will observe?

I can write it later.

Go and see for yourself.

Observation diary of holly, Hokkaido, pomegranate, peach tree and pine tree on campus today is Saturday. I went downstairs with my father to observe this pine tree.

We came under the tree and looked up. The first thing I saw was the triangular crown; The whole tree is as high as two stories; The trunk is thinner than my waist; Pieces of rough bark stuck to the trunk. In fact, when pine trees grow up, they will shed their old skins and grow new ones inside.

A closer look reveals that the leaves of pine trees are dense, needle-shaped and sharp. If you accidentally get stuck in a leaf, your hand will be very painful; This tree is also covered with tiny pine cones. I really want to pick a pine cone, but the tree is too high to pick.

The color of Ginkgo Garden is light green, which is different from the leaves of Fraxinus mandshurica. It consists of leaves and petioles, and there is a * * * wave at the top of its leaves. The whole looks like a fan. Ginkgo orchards sprout every spring. In summer, leaves grow into small fans. In autumn, leaves fall like leaves of Fraxinus mandshurica. When the breeze blows, they chase and play like lovely butterflies. This scene is really intoxicating. In winter, leaves that fall to the ground will be submerged by dust.

The leaves of Fraxinus mandshurica are dark green, with veins in the middle and many small serrations at the edges. If the leaves stand up, they will look like tumblers. The leaves of Fraxinus mandshurica bloom every spring, wither in the hot sun in summer, turn yellow in autumn, fall from trees, become bare in winter, just like an old man with hair, and finally all his hair falls out.

I'm sorry, I tried to find so many.

Willow's observation diary is urgent! Rows of willows are planted in our campus. Bright spring has arrived. Miss Chun took off the gray clothes of weeping willows, put on a light green coat, let the green jade fly on the branches, and the gentle branches danced. Tender branches, like many slender hands, happily accept the caress of the spring girl. Sometimes they dance gracefully with Miss Chun, and sometimes they perform wonderful acrobatics and go straight down to the ground. Every movement seems to express gratitude to the spring girl who gave it life. The willow branches in spring are so beautiful that they remind me of a poem "Jasper dressed as a tree, willow hanging green silk tapestry." I don't know who cut off the thin leaves. The spring breeze in February is like scissors. "The hot summer has arrived. A dense willow tree looks like "Lv Yun" from a distance. A breeze blew, and "Lv Yun" danced in the wind, and cicadas kept barking in the branches, as if to say, "It's so hot, so hot! "However, children are not afraid of the heat. You see, they are playing, singing, dancing and enjoying the cool in the shade. Golden autumn has come, and the leaves on the willow tree have changed from dark green to yellow-green, then light green and finally dark yellow. As soon as the wind blows, the leaves somersault and fly down like butterflies on the path, laying a yellow carpet for the path. Willow is not only so beautiful, but also has many functions! If there is a fire, you have to invite a willow expert! You wash its willow leaves, and then make tea to drink, and your fire will slowly disappear. If you think the bamboo basket you made before is not delicious, please invite Uncle Liu! You pick all the leaves, go back to make tea, and weave the willow branches into wicker baskets. You can also weave flower baskets with willow branches and hang them on the wall as decorations. It will be beautiful. I love willow, and I love willow all the year round.
