What is the growth rate of bamboo?

Bamboo grows taller faster than other plants of the same size, mainly because the branches of bamboo are divided into multiple nodes and grow at the same time, and other plants of the same size are usually growing at the apical meristem. Moreover, the hollow stems of bamboo are much lighter than the stems of woody plants of the same size.

Bamboo grows at a fast rate. During the rainy season, bamboo grows at a rate of 150 cm to 200 cm per day. Bamboo grows at its slowest rate, growing at a rate of 20 cm to 30 cm per day.

Different species of bamboo grow at different rates. Moso bamboo can grow 15 meters and 18 meters tall in 30 days and 40 days, and dragon bamboo can grow 30 meters and 35 meters tall in 100 days and 120 days.

The growth cycle of bamboo is 60 years, it will grow from shoot buds to bamboo shoots, and then new bamboo will grow, but the height will not continue. When the bamboo blooms, it will lose its leaves, which also means that the bamboo will face death. Generally, it grows in May, and in the cold winter, it stops its physiological activities and recovers when the temperature rises.

This has nothing to do with the "energy point of view", and the photosynthesis efficiency of bamboo is not outstanding. The photosynthetic area of bamboo per stem is about 28 square meters, and the annual carbon sequestration capacity is about 16 kilograms. Some people don't know that bamboo is meristem through bamboo whips (underground stems), and think that bamboo shoots expand their volume alone, which naturally seems very surprising - but many woody plants also have large-scale underground root systems, forming clonal groups, and their aboveground parts grow much slower than bamboo.

Bamboo, of course, has an effect on the soil. A number of studies around the world have shown that bamboo has a certain effect on the condition of newly planted soil in the short term, but due to the large biomass, rich nutrients and short production cycle of bamboo forests, after several rotation periods, the soil nutrient output is greater than the input, which will lead to the gradual impoverishment of the soil of bamboo forests. However, the decline in fertility caused by bamboo can be effectively counteracted by human fertilization, and it can be planted and harvested for a long time.

Plants do not directly absorb energy from the soil and transform it into "organic matter", its "organic matter" is the product of photosynthesis, the energy comes from sunlight and other rays, and the material is carbon dioxide in the atmosphere, water absorbed by roots, etc.

During plant growth, essential nutrients such as nitrogen, phosphorus, and potassium are obtained from the soil, which affects the fertility of the land. The amount of nutrients required by different plants varies greatly, and this is not absolutely related to the growth rate of the plant.

The effect of bamboo on the soil has been well studied, and its planting density can be controlled to reduce the adverse effects.

The growth process of bamboo is a natural process from vegetative growth of asexual reproduction to sexual reproduction and reproductive growth of the generations, with a cycle of about 60 years.

After the bamboo blooms and bears fruit, the bamboo stalk loses its leaves, and no longer grows new leaves, until it withers and dies, and the underground bamboo whip of the bamboo no longer germinates new roots and bamboo shoots, and turns black and rots. Under normal circumstances, bamboo grows only to grow taller, not thicker, and the thickness of the bamboo is determined by the thickness of the bamboo shoots.

The growth of plants should go through germination, rooting, growth, flowering, fruiting, and finally producing seeds, which is called completing a life cycle, some plants complete a life cycle in a year or less than a year, and the plant dies with it, this kind of plant belongs to annual plants; Some plants take several years of growth before they begin to bloom and bear fruit, but the plants can live for many years, and this type of plant is a perennial plant. Although bamboo can live for many years, it is not like common perennials, which can bloom and bear fruit many times in a lifetime, but only blooms and bears fruit once, and the plant dies after fruiting, so it is a perennial flowering plant.

When does it take for bamboo to bloom? Bamboo blooms during periods of abnormal weather, especially drought. In addition, due to the criss-crossing of underground stems and the exchange of nutrients, bamboo often blooms and dies in patches, which is a special physiological phenomenon that bamboo is different from other plants.

Therefore, we don't want to see bamboo bloom, and we hope that bamboo will always be so lush, verdant and lovely.

The bamboo growth cycle is about 4-8 years, the plant grows from bamboo shoots to bamboo shoots, and then grows new bamboo, the whole process is very long, and the bamboo will lose a large number of leaves after flowering, when the temperature is too low, it will enter a dormant state, and the spring and summer of each year is the most vigorous period for the growth of bamboo, and it needs to be applied urea or nutrient-rich compound fertilizer.

The bamboo growth cycle is about 4-8 years, the plant growth rate is very slow, it takes 2-3 years to grow from bamboo shoot buds to bamboo shoots, and bamboo shoots will slowly mature after 2 years of growth, so as to germinate new bamboo, at this time the bamboo will not grow taller again.

Spring and summer are the most vigorous season for bamboo growth, after the spring comes, the roots of bamboo will germinate some small shoots, at this time it is necessary to apply fertilizer to the bamboo to promote the growth of the root system, mainly based on urea and well-rotted compound fertilizer.

In the process of cultivating bamboo, pruning work is very important, it is necessary to cut off yellow leaves and rotten leaves, and after the bamboo roots rot, they should be pulled out immediately, and the disinfectant water solution should be poured in the soil to prevent bamboo from being infected with diseases.

Bamboo has poor cold tolerance, when the temperature is too low, the epidermis will yellow and wilt, enter a dormant state, when cultivating bamboo, it is necessary to provide a warm, sunny environment, and the winter temperature can not be lower than 10 degrees Celsius.

The growth process of bamboo is as follows:

1. The bamboo slider can be divided, buried, whipped, and sown so that the seeds can be propagated. There are many types of bamboo, and different forms of bamboo reproduce in different ways, but generally from asexual reproduction to sexual reproduction;

2. After the bamboo roots sprout, they will grow into bamboo shoots. After the bamboo shoots break through the soil, the bamboo shell will slowly fall off, and then the branches will grow taller quickly. When the bamboo grows old, it will blossom and bear fruit and begin to shed its leaves until it dies.

Uses of bamboo

In agriculture, the use of bamboo is more widespread. Bamboo can be used to weave various agricultural tools, such as basket sieves, dustpans, brooms, drying mats, etc. The joints of the bamboo are used as water pipes for irrigation and water diversion in the fields. The Zigong salt area of Sichuan Province uses bamboo pipes to transport salt brine, which is low cost and durable.

The big bamboo stalk is cut off the bamboo green, tied into a bamboo raft, the draft is shallow, the buoyancy is large, and it is still the traditional means of transportation in the upper reaches of the inland river in southern China. In water conservancy projects, the bamboo is split into a sliver, woven into a gabion, and the stones are installed inside, which are enclosed on the bank to prevent the river bank from scouring, consolidate the embankment, and build a reservoir, which is widely used in the national famous water conservancy projects such as Dujiangyan.

In fishery production, bamboo is also widely used, from simple fishing gear to complex utensils, aquaculture fixed brackets and floating objects are made of bamboo, fishing boat nets, masts, canopies, hedges are also inseparable from bamboo.

In the bamboo shoot stage, it grows when it rains, but when it grows into a bamboo, it hardly grows. After three or five years, the bamboo will suddenly exert its strength and grow at an alarming rate, and if you come to the bamboo forest in the dead of night, you will hear the sound of bamboo growing in joints. It grows at a rate of two feet per day.

Bamboo is the fastest growing plant with a maximum record of one centimeter in length.

There are four main stages in the growth of bamboo, which are seedling stage, leaf growth stage, flowering and fruiting stage and dead stage. During the growth of bamboo, it spends most of its time growing vigorously.

The process of bamboo growth is from asexual reproduction to later sexual reproduction, and the general cycle is 60 years.

1. First grow into bamboo shoots through root germination, and before the bamboo grows out of the ground, it grows through bamboo shoots.

2. Then after a period of time, in spring, the bamboo shoots will be unearthed, and slowly the outer shell will come off, and then the bamboo branches will be pulled out from the middle.

Bamboo. 3. The bamboo will begin to be jointed, and it can grow to a height of more than ten meters in just a few months, but under normal circumstances, the bamboo will just continue to rise and will not become thicker again.

4. After the bamboo blossoms and bears fruit, the bamboo stalks begin to lose their leaves, and no new leaves will grow until they become yellow and die.

The required environment for various types of bamboo is different, and moso bamboo likes to grow in places with high humidity and cannot be exposed to strong sunlight. Luohan bamboo needs sufficient light to replenish its growth, otherwise it will affect its growth form. Square bamboo needs to grow in a shady place, otherwise it is difficult to plant.
