Observe the plant cactus.

There is a strange plant in my house, and its name is cactus. Do you know where the name of the cactus comes from? Let me tell you: because it resembles the palm of a human hand, people call it a cactus!

When the cactus first grows, it is green, and its body is covered with many small thorns, and those thorns are very soft to the touch, and when a breeze blows, the thorns of the cactus dance with the wind, which is very beautiful!

After a while, the cactus turned emerald green, and that green made people look so dazzling, so comfortable, so fresh. The small soft thorns on its body have also become hard, like steel needles. After some time, another flower bone grew on it.

Slowly, it grew bigger and bigger, and finally a big red flower bloomed, which looked so beautiful! According to my grandmother, it is not easy to see cacti bloom, because cacti only bloom once in many years.

The cactus is not very pretty, but every piece of its body is a treasure!

Cactus is highly nutritious and rich in potassium, calcium, zinc, phospholipids, vitamins, fiber, etc. According to the records of "Materia Medica", cactus has the effect of invigorating qi and blood, clearing heat and detoxifying, and it can also reduce swelling and relieve pain, strengthen the spleen and stop diarrhea, and calm the nerves and diuretic.

My favorite is the cactus flower. Have you seen it? According to my grandmother, cactus flowers come in many colors, including red, white, purple, orange, and so on.

These flowers not only beautify our surroundings, but also make the indoor air fresher. When the flowers are gone, you'll see the fresh flesh of the fruit and you'll want to take a bite, but you'll have to be careful, it's not fun to have its hard thorns pierce you!

Friends, after listening to my lectures, you must really want to raise a pot of cactus, right? Okay, go and raise a pot!

On the first day, I picked a few garlic pieces, peeled them and put them on a plate filled with water, and I waited for them to sprout.

The next day, a hole was cracked at the top of the garlic, and the buds inside could be seen, and about 2 mm of white roots grew at the bottom.

On the third day, some of the garlic sprouts grew about 1mm in size, and I put them on the balcony to bask in the sun, and they scrambled to grow taller.

On the fifth day, the garlic seedlings grew taller and greener, some of them had 2 leaves, and the roots were longer and intertwined.

Many days have passed, and the small sprouts have grown into blue-green garlic seedlings, about 20 cm in size. Dad said that if you only cut the leaves, they will still grow. So I cut the garlic leaves, and my father fried a plate of garlic sprouts for me to return to the pot meat, which was very fragrant!

By observing the growth of garlic seedlings, I learned that the life of garlic seedlings is only a few dozen days.
