As an important industrial raw material and agricultural cash crop in the world, cotton can be seen everywhere in our daily lives. However, many people do not know much about the growth habits and classification characteristics of cotton. The most confusing thing is whether cotton belongs to a woody plant or a shrub? This article will conduct an in-depth exploration of cotton-related issues and answer this question for everyone.
1: What is cotton?
In our daily life, cotton is a very popular plant. It is a kind of vegetable that produces fiber. Because of its soft fiber, strong water absorption, good warmth, and good breathability, it is widely used in the textile industry, sanitary product manufacturing and other aspects.
2: The origin and types of cotton The origin of cotton is very extensive, mainly distributed in tropical and subtropical regions. The world's major cotton-producing areas include the Americas, China, India, Pakistan, Uzbekistan and other places. There are also many types of cotton, which can be divided into fiber cotton, Shihua cotton, camellia cotton and other varieties according to their uses and growth habits.
3: Cotton growth habits Cotton is a crop that is relatively drought-tolerant, warm and has sufficient light. It likes irrigation, but is not tolerant to waterlogging. It needs to be at temperatures above 20 ° C to grow vigorously, and its growth period is generally about 120-150 days. Cotton requires a large amount of nutrients such as nitrogen, phosphorus and potassium fertilizers during its growth process.
Four: The roots and stems of cotton The root system of cotton is relatively developed and can be divided into two types: large roots and lateral roots. The cotton stems are round or square with villous surfaces and can be 3-5 meters tall.
Five: The leaves of cotton and the leaves of flower cotton are heart-shaped or palm-shaped, with long handles or no handles. Cotton flowers are very beautiful, usually white or light yellow, with 5-8 petals and a flower diameter of 3-5 centimeters.
6: Cotton fruit The fruit of cotton is generally a capsule, conical or oblate shape, with villous surface. Ripe cotton fruits will crack, exposing the cottonseed inside.
7: Is cotton a woody plant or a shrub?
Whether cotton belongs to a woody plant or a shrub is a difficult question to answer. According to botany classification standards, cotton should be considered a woody plant because it has strong stems and developed root systems. But judging from the appearance and growth habits of plants, cotton is more like a shrub.
8: Why does cotton have such characteristics?
We can explain why cotton has such characteristics through its growth habits and genetic characteristics. Cotton needs to adapt to dry environments in nature, so it needs strong roots and stems to store water and support leaves and fruits. At the same time, since most of its growing areas are located in low latitudes, with sufficient light and high temperatures, the leaves and flowers of cotton will soon fall off, leaving only wooden stems and fruits.
Nine: The importance of cotton Cotton plays an extremely important role in human society. It is one of the raw materials in the textile industry and an indispensable item in people's lives around the world. Moreover, as an agricultural product, the cultivation and sales of cotton also play a positive role in rural economic development.
Ten: Advantages and disadvantages of cotton The advantages of cotton are mainly soft fiber, strong water absorption, good breathability, and good warmth retention. However, it also has some shortcomings, such as long growth cycle, high requirements on water, fertilizer and soil, and easy infection with pests and diseases.
XI: Cotton's ecological and environmental problems With global warming and environmental degradation, cotton's ecological and environmental problems have gradually become prominent. Cotton cultivation requires a large amount of water resources and pesticides such as pesticides and chemical fertilizers, which will cause certain pollution and damage to land, water sources and the ecological environment.
12: Future development of cotton In order to solve cotton ecological and environmental problems, future cotton planting will pay more and more attention to green production, ecological planting and sustainable development. Some new cotton planting techniques and varieties will also gradually emerge to adapt to different regions and different market needs.
XIII: Cultural and Historical Value of Cotton Cotton also plays a very important role in human culture and history. Since ancient times, cotton has been widely used as an important textile raw material and has also become a symbol of some cultural and religious traditions.
14: How to buy high-quality cotton products?
When purchasing cotton products, we should pay attention to the quality and production process of cotton. High-quality cotton products should be products that meet or exceed national standards in many aspects such as softness, breathability, sweat absorption, and antibacterial. At the same time, we should also choose cotton products with ecological certification and environmental protection labels.
Fifteen: Through in-depth exploration of cotton's growth habits, characteristic classification and ecological environment, we can better understand this important agricultural cash crop. Although there is still controversy about whether cotton is a woody plant or a shrub, we can conduct in-depth research on cotton's form, function and ecological environment to provide better protection and development for the planting and application of cotton.
