What's the weather like for planting flowers?

Yulan got its name because it likes to blossom in rainy days. Many people find that when it is near rainy days, Yulan usually blooms like leeks. It's really beautiful.

Why does Yulan like to blossom in the wind and rain? The reason is that when it grows to a certain mature stage, sufficient rain can make the flower buds germinate quickly, and it takes three or two days to bloom, while the hot and humid environment before rain can stimulate it to prepare for flowering.

Therefore, we can also simulate a "artificial rainfall". First, dry the rain orchid in the sun for four or five days until the leaves are short of water, then soak it in a basin for 20-30 minutes, or soak it in a large basin of water. After drinking enough to bask in the sun, the flowers will be brushed together ~

four o'clock

Jasmine, also known as cordate telosma and thunder flower, is a common flower in summer and autumn. It likes to bloom at night, and it has a fragrance that can be faintly smelled far away.

When I was a child, the old man at home said that Mirabilis jalapa could predict the weather, but it might not be observed at night, because it was too dark, so I had to come and see it the next morning.

The sun rises early in summer, and the old people at home get up early in the morning, around 6 o'clock. If Mirabilis jalapa closes and withers soon, it means it will be sunny today.

If Mirabilis jalapa stays open, it will be cloudy or rainy today. In short, the sun will not be very strong. In the past, science and technology were not developed, so it was wise for people to summarize the weather rules by observing plants ~

willow leaf

Willow leaves in summer, swaying with the wind, can also be used to predict the next weather. As the saying goes, "willow leaves turn white and rain is coming." When the willow leaves turn white, it means there will be a heavy rain.

This phenomenon is easy to explain. Before it rains, the willow leaves will fly up and down, revealing a whiter back. Why? According to the relevant explanation, there are mitochondria and chloroplasts on both sides of willow leaves, with more chloroplasts on the sunny side and more mitochondria on the negative side. Before it rains, the air pressure decreases, the oxygen near the ground increases, and the willow leaves on the backlight side turn over, reducing breathing and saving energy.

Therefore, by observing the front and back of willow leaves, we can simply judge the coming weather. There is also a saying that if you see red roots growing near the roots of willow trees, it also means that there will be more rain in the last month or so. This is actually because the air humidity is high, and the willows grow air roots.

Pumpkin burning

The tip of pumpkin vine can also judge the weather. Generally, pumpkins are slightly smaller with a small curly vine bud in front. This vine is facing up, which means there is plenty of sunshine.

If the top sags slightly, it means it's going to rain.

It is still very accurate to predict the weather with pumpkins. If it has been raining recently and you accidentally see the pumpkin being lifted again, it may be sunny soon ~

pinecone

Pine cones made of pine trees can also predict the weather, especially in summer. If you see that the scales of pine cones are closed, it means that it is cloudy and wet, or it is going to rain soon.

The scales of pine cones are very sensitive to humidity. The air before heavy rain in summer is mostly hot and humid. At this time, the balance will be closed. Not only do fresh pinecones have this reaction, but even pinecones that have been picked for many years will be closed in rainy weather.

The rain has stopped. If the weather turns fine and the air dries up slowly, the pine cones will automatically open scales. Isn't it amazing ~

moss

The moss here refers to the common cyanobacteria in water. There is an old saying that "the river is covered with moss and it is about to rain". It may rain when you feel the water grass floating in the river.

The principle of this proverb is that before it rains, the water is stuffy, the air pressure outside is high, and the air pressure on the water surface is low, so the aquatic plants in the water will slowly float up and feel green when looking at the water surface.

Therefore, if a flower friend with a small pond at home sees that the water suddenly turns green, it may change, so hurry up and clean it up ~

Mimosa pudica

The biggest feature of mimosa is that it closes as soon as it touches the leaves, and it reacts quickly. If one day is not sensitive, it may rain or be played to death ~

In general, if you touch the mimosa leaf, it will close quickly and open slowly later. When it is about to rain, the reaction is much slower. The leaves are closed, but they are not completely closed and open again.

Many people can't help teasing mimosa when they see it. In fact, it is quite harmful to it. It is said that the leaves of mimosa are closed in about 0.088 seconds after being stimulated, and slowly spread out after a while, and the whole recovery time is 5 ~ 10 minute.

If you tease the mimosa repeatedly and always touch its leaves and stimulate it, it may become "tired" and finally numb. Under the continuous stimulation, the cell fluid that controls the opening and closing in the body has been lost and cannot be replenished in a short time, so it is "paralyzed" and may seriously lead to the death of wilted children.

cogon

Thatched grass is an outdoor strip weed with sharp leaves, which easily condenses dew in the morning. If you want to judge the weather by it, it will usually be after noon.

Under normal circumstances, the dew on the thatch disappears at noon on a sunny day. If the thatch is still wet after noon, it means it will rain next.

Because before it rains in summer, it is mostly in a hot and humid state, the air humidity is high, and the water vapor condenses on the thatch, which is easy to form small water droplets. Some people may ask, why not look at other weeds? That's because thatched leaves condense water vapor more easily, so it is more obvious to observe.

Jujube flowers are mainly drought, and pear flowers are mainly waterlogging.

Jujube trees are relatively drought-resistant. The flowering period from spring, summer, May to July is now the time to bloom. You can observe the thickness (more or less) of jujube flowers. If there are many jujube flowers, it means that it is dry this year.

Dry weather is beneficial to the pollination and seed setting rate of jujube trees, and also affects the sweetness of jujube. A little dry. Although red dates are small, they are highly sweet. If there is more rain between flowering and fruiting, the yield of jujube will be less and the sweetness will be lower.

As the old saying goes, pear blossoms and jujube blossoms indicate the opposite weather, and pear blossoms in full trees indicate that there is enough rain, or it may be that there is too much rain and there is a danger of flooding.

Rain is more conducive to the production of pears, and the pears raised are not only large in number, but also full and juicy. The ancients used jujube and pear trees, two plants with different water preferences, to judge rain, which was really wise.
