According to the length and appearance of the fiber, cotton can be divided into 3 categories: the first type of fiber is slender (the length is within 2.5 to 6.5 cm), and it has shiny, including excellent quality island cotton, Egyptian cotton and pneumatic Marton; Long velvet cotton has low output, more consumed work, and expensive prices. It is mainly used for high -grade fabrics, cotton yarn and knitted fabrics.第二类包括一般中等长度的棉花（长度约1.3至3.3厘米）；第三类为纤维粗短的棉花（长度约1至2.5厘米）用来制造地毯、棉毯和价格低廉的织物，或与Other fiber blend. Cotton is one of the most important crops in the world, with high yield and low production cost. Cotton can make various specifications of fabrics. Cotton fabrics are firm and wear -resistant, can be washed and ironed at high temperatures. Cotton wetting and moisturizing and moisturizing quickly make it comfortable to wear. The main and by -products of cotton have high utilization value, as the predecessors said, "cotton is a treasure." It is not only the most important fiber crop, but also an important oil crop. It is also a high -protein grain crop. It is also textile, fine chemical raw materials and important strategic materials. Therefore, we must work hard to increase the production of cotton, make a good use of comprehensive utilization, increase yield and value, to increase the income of cotton farmers and meet the needs of the national economic development. The use of the other personality is a beauty product for skin care anti -wrinkle. Cotton is also an important honey source: cotton is divided into three types of honey glands, bud leaves, and flowers, and often blooms the honey gland of the honey gland of the forest. The flowering period of cotton in the middle and lower reaches of the Yangtze River is from late July to early September. The provinces in the middle and lower reaches of the Yellow River are early July to early August, and Turpan in Xinjiang is from mid -July to early September. The large flowing honey period is about 40 days, and the temperature of the honey is 35 ° C. Xinjiang cotton area generally produces honey 10 to 30kg, up to 150kg. In other cotton areas, pesticides are frequently applied due to frequent flowering periods, and the bee is too heavy. The value of honey source is greatly reduced. Group production is generally 10-20kg. Since the 1980s, the area of cotton area has grown rapidly across the country. Some provinces and regions have actively promoted biological control technology. It has become the main local honey source according to the length and appearance of the fiber. Cotton can be divided into 3 categories: the first type of fiber is slender (the length is in the length (the length is in the length (the length is in the length Within 2.5 to 6.5 cm), there is shiny, including excellent quality island cotton, Egyptian cotton and pneumatic malaxia; long cotton production is low, expensive, and expensive, mainly used for high -grade fabrics, cotton yarn and knitwear fabrics Essence第二类包括一般中等长度的棉花（长度约1.3至3.3厘米）；第三类为纤维粗短的棉花（长度约1至2.5厘米）用来制造地毯、棉毯和价格低廉的织物，或与Other fiber blend.
