How to make a maple leaf red? 10

Maple leaves turn red because the leaves contain a lot of anthocyanins.

for the sake of it. Anthocyanins, also known as red pigments, are located in vacuoles in leaf cells. Unlike other pigments in the leaves, it is not involved in photosynthesis. The main role of the leaf is through photosynthesis.

Obtain the sugar and carbohydration needed for tree growth.

Compounds and other nutrients. As a site for photosynthesis of leaves, chloroplasts.

It contains not only the leaves.

The tablets appear green in chlorophyll.

It also contains carotenoids that can give the leaves a yellow color. In summer, the leaves are high in chlorophyll, so the bright green overshadows the yellow. With gas.

As the temperature drops and the daylight hours become shorter, chlorophyll is broken down in large quantities, revealing other pigments such as carotenoids that are submerged in the leaves.

How do you make the green leaves of a maple bonsai turn red again?

Scientific experiments have proved that in addition to chlorophyll, lutein, carotene and other pigments, plant leaves also have a special pigment called anthocyanins, which is a kind of "chameleon", which is red in acidic liquid. In autumn, the temperature decreases and the light weakens, which is beneficial to the formation of anthocyanins, while the leaf cell sap of red leaf trees such as maple trees is acidic, so the whole leaf is red. In this way, Zhao Yi of the Qing Dynasty in the poem "Wild Steps" "is the most nosy in the autumn wind, red his maple leaf white head", but "who dyes the maple forest drunk" is more scientific.

The tall tree in front of us is the maple tree, and when autumn comes, the leaves turn red, and I believe that everyone can see the intoxicating scenery of "frost leaves red in February flowers" when you go to Niumlin in autumn.

The black box is manually lit to control the temperature and lighting time ......It's a bit of a hassle, but I can't think of anything better.

Ways to make a maple leaf turn red quickly:

1. Increase the temperature difference: If you want the red maple leaves to turn red fast and look good, there must be a temperature difference of at least 10 degrees during the day. If the temperature difference in your home is too small, try to expose the red maple potted plants to create a suitable temperature difference.

There is really no way to raise it in the open, so open the window at night and put the red maple in front of the window. If the red maple is kept in a closed room 24 hours a day, the leaf color will definitely not be as fast as the open one. Like the current weather, the temperature in many areas has dropped below 15 degrees at night, and the leaf color of the red maple will change greatly after two or three days.

2. Sufficient light: If the red maple wants to be red, it can't do without the sun, and now it must be sunned, how long can it be sunned. Sufficient light is the key to the red maple turning red, if the light is insufficient, not to mention the whole leaf is red, it is difficult to redden.

The indoor maintenance of the red maple can be opened more windows during the day, and it is not the same as direct sunlight and drying through the glass, and you will understand after drying it.

3. Apply potassium fertilizer: If the temperature difference of the red maple at home is also enough, and the light is enough, it is not red, apply some potassium fertilizer, potassium fertilizer can make the leaves red. At this time, it is best to apply inorganic fertilizer, which is chemical fertilizer, and the effect is fast.

The effect of organic fertilizer is not obvious, and the effect is not as good as that of inorganic fertilizer. However, don't apply fertilizer too strongly, and be careful to burn the leaves. Thin, apply it once every ten days, and the leaves will be almost red after two times.

4. Keep the soil slightly acidic: red maple likes slightly acidic soil, and if the soil is too acidic or alkaline, the leaves will be red slowly and not completely. If your red maple is often watered directly with tap water, or the soil planted in the north is dug directly in the field and has not been pH adjusted, you can pour a little ferrous sulfate solution on the red maple to make the soil slightly acidic, and the leaves will be red and look better.

If your red maple usually pays more attention to the pH of the soil, and does not water tap water directly or rainwater frequently, do not acidify it again. To water flowers and plants ferrous sulfate, be sure to see the concentration on the instructions clearly, not too strong, otherwise burn the leaves!

When I went to Xiangshan, I thought about the poem of the **boss, the red leaves of Xiangshan are good, and the frost is thicker. I bought a souvenir for my classmates, and after many years, it was still very red and dyed!

1. Yuelu Mountain in Changsha, Hunan Province turns red in mid to late October (the ninth month of the lunar calendar).

Location: Aiwan Pavilion, Huangxing Tomb, extremely high and piercing stone slopes, piercing around the quiet stone lake, piercing stone slope pavilions, etc.

Varieties: There are many varieties, including sweetgum, maple, maple, Japanese red maple, North American maple, autumn flame, October red, Norway maple, sunset red, autumn flame, Yuanpage maple and other varieties.

In addition to the maple leaves of Yuelu Mountain, the maple leaves of Orange Island Scenic Area, Martyrs Park, and Provincial Botanical Garden have turned red 10 days ago, earlier than Yuelu Mountain. Yang Xikun, a senior engineer of landscape architecture at the Changsha Institute of Landscape Sciences, explained that due to the microclimate environment, the landscape maple trees in the park and the maple trees on the roadside experienced the bright change of the temperature difference between day and night earlier, and turned red earlier; The climate in the mountains is cool all year round, and the maple leaves must be red later.

2. The maple leaves in Beijing Xiangshan are also called red leaves, which generally turn red in September (August of the lunar calendar).

The best time to see the leaves is from mid-October to mid-November, and each stage has a different mood from red to fall.

Xiangshan autumn leaves are very famous in Beijing and even in the whole country, and the tourists who watch the autumn leaves every autumn are crowded. After the autumn leaves enter the autumn Qicha Kuantian, the color turns red little by little, red like a flame, and after the frost falls, it will also appear deep purple-red. Autumn in Beijing usually begins in September, and the autumn leaves in Xiangshan can be enjoyed from late September to mid-November, a full two months.
