What are the benefits of defoliation for humans, and what are the benefits of plant deciduous leaves

In late autumn and early winter, you can see fallen leaves fluttering in the wind everywhere, and it dances like butterflies.

Autumn leaves are not as bright and green as the new leaves that grow in early spring, and autumn leaves are not as lovely as in the hot summer. But the fallen leaves of late autumn have a spirit of silent dedication.

When you see the half-yellow autumn leaves all over the ground, have you ever wondered: when spring comes, it has greened nature and brought life to people? When the heat comes, does it bear the roasting of the sun alone, shelter the sun, and hold up a cool world for you?

When the harvest comes, does it dedicate the fruit to you?

When the cold wind hits, the tree needs to hibernate and accumulate nutrients, and it resolutely drifts away with the wind, returning to the roots from the sweet leaves, and entering the soil as fertilizer, so as to continue to contribute to the reappearance of a lush, fruity world in the coming year!

We should be grateful for the fallen leaves and sing praises for its spirit of silent dedication.

Laid-off workers have been given the opportunity to find new jobs.

Tips for changing your outfit were sent to the clothing industry.

Give some unfamous directors a chance to start filming similar to "Winter Song".

Some children who care about the elderly are a sign of an increase in morbidity.

A sigh for those friends who didn't fall in love well in the summer.

The good thing for students is that they are inspired to write essays... And it's not cliché, at least for me.

Defoliation?? It's night.,A lot of girls are silently dedicating their bodies.。。。

Plants can reduce the area of transpiration and heat dissipation through leaf litter, and reduce water loss in the body, so as to adapt to adverse environmental conditions such as low temperature and drought. When the leaves fall on the soil, they are decomposed and the nutrients are reused by the plants. Its organic matter can also improve the physical and chemical properties of the surface soil, and improve the ability to retain water and fertilizer.

Recently, a new explanation has been proposed for the phenomenon of plant defoliation. They see defoliation as a process of excretion and competition by plants. This has often been overlooked by previous studies.

Wolman et al. (1980) found that plants living in metal-rich soils had leaves that contained low levels of aluminum, but that leaves that had fallen off contained high concentrations of aluminum. They analyzed the levels of various ions in 21 perennial plants grown under different conditions, and most of the plants shed leaves with higher calcium content than the growing leaves. There is no clear regularity between magnesium and sodium.

Elements such as lead, zinc, iron, and aluminum were higher than those of growing living leaves in almost all the tested leaves. The magnitude of changes in the content of various elements is also very different. High concentrations of heavy metals are harmful to any plant.

Accumulating heavy metal ions in old leaves and shedding plant bodies with defoliation undoubtedly has a positive effect. In this sense, defoliation is the excretory process of plants. Defoliation also increases the plant's ability to compete.

The defoliation of some plants can release interspecific inhibitors that hinder the growth of other plants. In forests, permanent defoliation reduces the amount of grass growing in the understory. Some people uproot weeds around fruit trees in the orchard, so that the fruit trees are more productive, and play a similar role to the defoliant layer.

The defoliant layer also provides a breeding ground for the germination of the seeds of the tree and the growth of seedlings, which is conducive to the reproduction of the species. Obviously, these characteristics play a positive role in the competition for survival. In the long evolutionary history, plants have been subjected to selection pressures from many aspects, and the leaf structure has become more complex and the functions have become more and more perfect.

The excretion and competition of deciduous leaves are conducive to the survival and development of whole plants and species.

Provide nutrients for the green environment.

The significance of defoliation: it is an adaptation of plants to reduce transpiration, retain water in the body, and survive the cold and dry seasons, and this habit is formed by plants in the long-term evolutionary process.

In autumn, due to the low temperature and reduced rainfall, the root absorption of plants is reduced, and the water and inorganic salts obtained by the plant body are greatly reduced, so that physiological activities such as photosynthesis, respiration and transpiration cannot be carried out normally. If the leaves are retained, a large amount of water will be transpired and threaten the survival of the plant. After the cold and drought, new leaves will grow.

The meaning of deciduous leaves.

The wind blew softly, and the leaves fell one by one.

Fallen leaves also have dreams, and they only hope to turn into spring mud and protect the big tree that gave birth to them forever.

But the good times were short-lived.

The relentless wind blew these leaves off, and the falling of the leaves did not represent sadness, but more importantly, joy'

Only a small life that loses its leaves can be exchanged for a big tree that can give birth to countless leaves!

1. The leaves are rich in vitamins and amino acids, which are not only nutritious but also cost-saving for feeding livestock. Like locust leaves, paulownia leaves, poplar leaves, etc., ground into powder, can be fed with cherry stool chickens, ducks, geese, pigs and other omnivorous animals.

2. It can make charcoal and honeycomb coal.
