Why does bamboo die after flowering, and why does bamboo die when it blooms

Bamboo flowering is a normal natural phenomenon and belongs to a process of bamboo seed reproduction. The ancient people of our country have long observed this phenomenon, in the "Classic of Mountains and Seas" more than 2,000 years ago: "Bamboo grows flowers, and its year will wither."

of the record. Dai Kai's "Bamboo Book" in the Jin Dynasty recorded: "The medicine must be sixty, and the compound is also six years."

Its annotation is: "Bamboo is easy to root in 60 years, and it is easy to grow strong and die." "However, bamboo is mainly vegetatively reproduced, and shoots grow from bamboo whips in the ground every spring, and then develop into new bamboo.

The bamboo whip is not its root, but an underground stem. Underground stems can be divided into three types: uniaxial underground stems can continue to grow, buds are born on both sides, and side buds develop into bamboo shoots; The apical bud of the axis type develops into bamboo shoots, the side buds produce new underground stems, which are connected to form the axis, and the underground stems produce dense clusters of bamboo stalks. In addition, there is a compound axial type, which is a hybrid type of the above two.

Bamboo's sexual reproduction, like other flowering plants, blooms first and then sets seeds, completing the entire growth cycle. There are three types of bamboo flowering cycles due to different types of bamboo: a small number of bamboos can bloom year after year, and the bamboo stalks do not die after flowering, and they can still whip and grow bamboo shoots; Most of the bamboo only blooms once in the whole growth process, and there is a certain period, ranging from 40 to 80 years, after flowering, the stem leaves are yellow, and the pieces die, and the underground stem gradually turns black, loses the germination force, and the seeds formed are the so-called bamboo rice, and the germination grows after planting, in order to grow into new bamboo, arrow bamboo and Chinese orange bamboo belong to this type; There is also a type of sporadic flowering that does not die after flowering, such as Cizhu.

Mandarin bamboo, large arrow bamboo, etc. all belong to the category of regular flowering. This type of bamboo blooms at a very long interval, usually 50 to 60 years: some even bloom once in nearly 100 years.

However, regardless of the year in which the bamboo poles grow, as long as the bamboo whips are the same or similar age, the flowering time is roughly the same. Even if the ecological environment is very different, such as sunny slopes, shady slopes, steep slopes, gentle slopes, different soils, and different altitudes, they can bloom at the same time.

When bamboo grows to a certain age, it will inevitably senescence and blossom and bear fruit before the end of life in order to reproduce offspring.

The flowering of bamboo depletes the nutrients stored in bamboo whips and bamboo poles, and most species, such as moso bamboo and pear bamboo, die in both the aboveground and underground parts after flowering.

A few bamboo species such as spotted bamboo, cinnamon bamboo, and Yazhu bamboo, the aboveground part dies after flowering, while the buds of the underground part can still be rejuvenated and renewed, and there are also individual bamboo species such as water bamboo, flower bamboo, etc., after flowering, the leaves of the plant remain green, and the underground part does not die. However, flower branches should be cut down as soon as possible to reduce nutrient consumption and ensure the normal growth of bamboo forests.

<> "Plants bloom and bear fruit is a common thing. However, bamboo flowering is extremely rare, occurring only once in decades, and is often accompanied by drought years, especially when the bamboos usually bloom at the same time and then a forest dies. Why does bamboo die after flowering?

The roots, stems, and leaves of plants are called vegetative organs, and their growth is called vegetative growth. The flowers, fruits, and seeds of plants are called biological organs, and their growth is called reproductive growth. The flowering habits of plants are divided into two categories, multi-flowering plants, such as apples and pears, which will bloom and bear fruit every year, and one type of one-time flowering plants.

For example, bamboo, a flowering plant will bloom once in a lifetime, which is characterized by the dominance of vegetative growth in the early stage of growth, and when the vegetative growth reaches a certain stage of transport, reproductive growth will gradually turn to dominance, and finally flowering and fruiting.

Because flowering and fruiting consume a large amount of organic nutrients, and these nutrients come from roots, stems, and leaves, most of the nutrients stored in the vegetative organs after flowering and fruiting are consumed, and they can no longer live, and they gradually die.

The reason for the flowering of bamboo is due to the natural aging of age, which is a normal physiological phenomenon of bamboo growth and development from quantitative to qualitative change. In addition, because of the dry weather and the lack of soil moisture, the concentration of sugar in the bamboo plant increases, and the vegetative growth shifts to reproductive growth, accelerating the aging cycle.

The fruit of bamboo is the main food of rodents, because the seeds are only grafted once in decades, and the animals do not know when to start, and bamboo effectively avoids the fate of the seeds being eaten, which is also a characteristic of bamboo that has evolved over a long period of evolution.

Summary. Hello dear, I can tell you that the reason why bamboos bloom and die is because they consume the reserves available to the bamboo itself, so that when there are no more reserves available, they wilt and die. In addition, according to the laws of nature, the process of bamboo flowering is also very time-consuming, and requires a certain temperature and humidity, so it is very difficult to meet the conditions for bamboo flowering, so once the small bamboo blooms, it loses the hope of life.

I can tell you that the reason why the bamboos bloom and die is because they consume the reserves available to the bamboos themselves, so that if there are no more reserves available, they will wither and die. In addition, according to the laws of nature, the process of bamboo opening socks and knowing flowers is also very time-consuming, and requires a certain temperature and humidity, so it is very difficult to meet the conditions for bamboo flowering, so once the small bamboo blooms, it loses the hope of life.

This is because bamboo flowering is a process of nutrient depletion, bamboo has a long flowering period, which will consume a lot of nutrients and energy, so that the growth rate of bamboo slows down, and even stops growing, resulting in the gradual weakening of the vitality of bamboo. In addition, after the flowering of bamboo, it will also cause a series of pests and diseases and die, which will accelerate the death of bamboo. Therefore, some people will choose to cut down the bamboo as early as possible to prevent the impact of the death of the bamboo on the surrounding environment.

Bamboo is a perennial lignified plant with above-ground stems (bamboo poles) and underground stems (bamboo whips). Normally, the nutrients produced by bamboo leaves are used to make the bamboo poles grow taller, thicker, longer branches and leaves, and longer roots, and the excess nutrients are transported to the bamboo whip.

The buds on the bamboo whip germinate, gradually hypertrophied in the soil, and unyieldingly upward, after unearthed, it is a fresh and tender bamboo shoot. When it grows up, it turns into lush bamboo. Bamboo generally lives for more than ten years or decades before flowering and setting seeds.

However, if there is a special adverse environment, such as abnormal drought, severe pests and diseases, or nutritional deficiencies, bamboo will also bloom early. When bamboo blooms, all the nutrients produced by bamboo leaves are used to flower and set seeds. Bamboo pours everything it has, concentrating all the essence into the seeds.

After flowering and seeding, the nutrients stored in the bamboo are also depleted, and it has also fulfilled its mission.
