This species is a cultivated species. According to its cultivated strains and varieties, it can be divided into four types: high type (commonly known as high banana, high bud banana or high banana), short type (commonly known as dwarf banana or dwarf banana), semi-high type and oil banana (with dark green and shiny skin). [ 1]
China is the origin and main producer of bananas. According to FAO data, by 20 15, the domestic banana production area will reach 43 1000 hm2, and the total output will be12.64 million t, making it the second largest banana producer in the world.
2. The growth process of bananas is the same as that of other fruits. Bananas bloom first and then bear fruit. Banana trees have big flowers.
A handful of bananas will grow under each petal.
Petals began to wither and a bunch of fragrant bananas grew.
Bananas continue to grow, and the flowers on their heads begin to fade.
Bananas continue to grow, and the original low head slowly turns.
The bent bananas we often see are basically shaped.
Bananas continue to grow and wait for harvest (bananas grown outdoors are often bagged to prevent pests and ensure the beautiful appearance of mature fruits)
3. Write the composition of banana tree in the first person. By planting bananas, everyone has embarked on the road of getting rich, which is very beautiful. Bananas are ripe and smell delicious. The trunk is so straight and smooth that I can't help peeling it gently. The meat is Huang Chengcheng, chubby, like a pearl. Bite it down, it's fragrant, sweet and slippery, which makes people want to eat. Banana is a cash crop, and the people in my hometown are hardworking, which is our paradise. Several banana trees seem to be our loyal friends, accompanying us every day.
From a distance, the banana tree looks like a graceful fairy, like a banana fan in The Journey to the West, which is intoxicating. Look at this golden banana. These huge "fans" provide us with shelter from the rain and have many functions. The big bud has been fully unfolded, revealing the small white bud. Careful observation, rows of bananas are like curved crescent moons, arranged neatly, banana leaves extend around, and buds compete for small bananas. As time goes by, the buds spread out and are waving to people enthusiastically. The breeze is blowing, and the banana trees in the garden are dancing. The banana trees are sprouting purple buds, which are banana buds.
Plant several banana trees in the small yard next to Fourth Street every time.
4. The growing environment of bananas is a large perennial herb monocotyledonous plant. Its underground stem is a thick bulb from which roots, stems, leaves, flowers, fruits and sucking buds (for reproduction) all grow.
Bananas like high temperature and humidity, generally grow at 20~35℃, and the optimum temperature is 24~32℃. The critical temperatures of organs are 10~ 12℃ for leaves, 13℃ for fruits and 15℃ for roots. The annual average temperature is above 265438 0℃, which is the main distribution area of bananas, and a few are distributed below 20℃. Banana plants have high water content, large leaf area and large transpiration, so the water demand is also large. The average monthly moisture content of bananas is 200 ~ 300mm, at least not less than 50mm. Bananas need plenty of sunshine, but not too much. It is reported in the literature that when the light intensity increases from 2000 lux to 10000 lux, the photosynthesis increases rapidly, but when the light intensity increases from 10000 to 30000 lux, the photosynthetic efficiency increases slowly. Insufficient light will lead to poor luster and flavor of fruits. Bananas have no main roots, while normal plants have 200~300 fibrous roots. 10~30 cm soil layer is the main distribution layer of root system. Bananas have high plant height and shallow roots, and are very sensitive to wind, and are easily affected by typhoons and strong winds. It is observed that when the wind speed reaches 25~30 km/h, the leaves can be severely torn, when the wind speed is 40~65 km/h, the false stems are often broken, and when the wind speed is 100 km/h, the banana orchard can be completely destroyed. Bananas have extensive adaptability to soil, but alluvial soil or humus loam is the most suitable. PH 4.5~7.8 can be planted, but pH 6.0 is the most suitable.
Banana adopts asexual propagation, and its seedlings include sucking seedlings and tissue culture seedlings. (1) There are three kinds of bud-sucking seedlings, namely: ragged buds (which were sucked before beginning of winter, and some scales died like ragged leaves after winter, hence the name), red bamboo shoots (which were sucked after spring, and their leaf sheaths were red, hence the name), and flying over mountains (which were sucked from the heads of old bananas harvested for a long time, also called water buds), among which ragged buds were used. (2) Tissue culture seedlings grow neatly and are suitable for planting when the leaf age is 6~ 10 leaves. Tissue culture seedlings are easy to mutate, have weak growth potential and poor stress resistance, and should be carefully managed in the early stage of growth.
The high-quality and high-yield techniques of banana (anti-season banana), cultivated banana, pink banana, dragon tooth banana and tissue-cultured banana (in vitro seedling) vary with seasons and varieties.
Banana diseases include banana bunchy top disease, which is a worldwide serious virus disease. Common control methods include: improving disease resistance and aphid resistance, planting disease-free seedlings, digging out diseased plants and rotating crops. In addition, more than 60 kinds of aphids spread banana mosaic heart rot and virus diseases. In addition, there are leaf spot, banana black heart disease, banana Panama disease, banana anthracnose, banana crown rot and banana root-knot nematode disease. Banana pests mainly include banana weevil, banana wheat leaf worm, banana aphid, banana flower thrips and so on.
There are many fruits, but I like bananas. Today, my mother bought a bunch of bananas. Let me introduce them to you.
Immature bananas are turquoise and taste bitter and astringent. A bunch of ripe bananas is like a small raft in Huang Chengcheng. I really want to sit on it and watch the beautiful spring scenery.

Peeled skin is like an open petal, revealing yellowish flesh inside. Smell it carefully. It smells good. I can't wait to take a bite, ah! Sweet and fragrant, sweet to my heart.
I found that there are many small black spots in the middle, which are banana seeds. Because it doesn't have enough reproductive ability, it can't be planted. I wolfed down bananas.
I still want to eat after eating, which is really memorable! Bananas can not only be eaten directly, but also be made into sweet and delicious milk tea and various fruit platters.
Bananas also have many functions, such as promoting fluid production to quench thirst, moistening lungs and smoothing intestines, clearing away heat and toxic materials, lowering blood pressure and improving immunity. They are suitable for people with hypertension and constipation. Bananas are high in nutritional value and rich in vitamins, so eat more bananas.

The flesh is white, and there are many seeds smaller than sesame. Bananas are sweet.
Immature bananas are difficult to peel, even if peeled, they are not delicious and have a little bitter taste. Ripe bananas open as soon as they are peeled off. They taste sweet and delicious.
I have loved bananas since I was a child, and my mouth watered when I saw others eating bananas. Once I ate five or six bananas, and finally I couldn't even eat.
I just realized that bananas can be eaten as food, but they will be digested soon. Do you know that?/You know what? Do you know that?/You know what? Eating bananas is good for your health.
Bananas grow in tropical areas, and when they grow on trees, they are clustered. People always pick bananas when they are not ripe, so as not to fall off the trees when they are ripe.
After picking, people suffocated the bananas. I'm telling you, banana trees are not trees. Its growth is different from other trees. Can you learn more about why banana trees are not trees? You answer this question. Banana is a tropical plant, yellow. I saw a banana tree in the tropical botanical garden. This is a small banana tree with only three bananas.
Bananas are curved. They are like boats and the moon. Banana has nine close friends. They live happily together.

It has a beautiful "coat", as long as you peel off the "coat", then golden meat will be displayed in front of your eyes. When you take a bite, the tip of your tongue will touch the smooth meat of the banana, making people feel delicate and soft.
Bananas are blue first, then golden yellow, and finally almost glow. It won't really shine, it won't really shine, because it's too smooth, so it looks like it will shine. Everyone has to go through one thing before they like to eat a fruit, right? Only after one thing, I fell in love with bananas.

8. Observe the composition of banana trees in 200-250 words: What did you find? Today, the teacher asked us to keep an observation diary, but I can't think of anything to write. But when I went to my teacher's house in the afternoon, I met many banana trees. Ha ha! Now we have a goal!
That banana tree looks like a mighty PLA uncle. Bananas on the banana tree are full, but the only drawback is that bananas are green, because they are not mature yet. Bananas are ripe. Someone must have picked them.
Today is my second day of observing the banana tree, but I found something purple under the banana. Sharp as a drop of water. Like petals, one piece wraps the other. But the branch between the banana and the flower has a shell like a screw, which is very special. After a while, I turned my eyes to the banana tree again. Bananas are much yellower now than on the first day. I believe these bananas can be eaten soon.
Today's fruit is very yellow, a bunch of fragrant bananas turn yellow, purple flowers slowly shed their shells, and there are more and more bananas. It's like brothers hugging each other, jumping on the tree together and laughing happily! I still silently said to myself,' These bananas must be delicious!
9. Find the appearance of bananas in the process of growth, and use words instead of writing the growth process.
As long as the demand of banana is met, it will continue to grow regardless of season. A banana bulb grows a long branch, which is 9 to 12 months long, bears fruit and then dies. Then the bulb is photographed again and goes through the same process. The only way to kill banana plants is to destroy bulbs that are sensitive to cold and humidity. Because bananas are plants all year round, they are often affected by inappropriate growth conditions.
Growth process
As long as the demand is met, bananas will continue to grow, regardless of the season. Banana bulbs take a long shot, only 9 to 12 months long, and then die. The light bulbs are then photographed separately and go through the same process. Only in this way can the banana factory be killed by destroying bulbs sensitive to cold and humidity. Because bananas are plants all year round, they often lack growth conditions.
root rot
According to California Rare Fruit Growers Company, root rot is the biggest killer of bananas. When the soil of banana becomes too cold or too wet, root rot will occur, leading to bulb rot and death.
prevent
Bananas may stop growing at 40 to 50 degrees Fahrenheit and stop demanding water during this time. Limit watering at low temperature and plant banana plants to keep the soil dry and warm and prevent root rot.
solution
The factory is always kept in the correct and banana bulb condition to avoid root rot. Bananas need to be drained quickly, and soil and websites should be completely drained under continuous watering and 70 to 80 degrees Celsius. Cold weather will stop the growth of plants and may make bulbs fragile.

prevent
Bananas may stop growing at 40 to 50 degrees Fahrenheit and don't need so much water during this time. Limit watering at low temperature and wrap banana plants to keep the soil dry and warm and prevent root rot.
solution
Always plant and maintain banana bulbs in the right environment to avoid root rot. Bananas need fast-draining soil and completely drained sites, continuous water and temperatures of 70 to 80 degrees Fahrenheit. Cold weather will hinder the growth of plants and may make bulbs fragile.
