棉花是我国最重要的经济作物之一,同时,中国又是世界上最大的纺织品生产国和消费国。棉花生产涉及2亿棉农的生计和近2千万纺织工人的就业,因此,棉花在我国国民经济中具有举足轻重的地位。但是,随着棉纺织业的发展,目前我国棉花生产面临总量严重不足和纤维品质偏低等问题。提高棉花的产量、改进其品质,对增加棉农收入、促进我国纺织业持续健康的发展,具有十分重要的意义。 Cotton is one of the most important cash crops in the country. At the same time, China is again the world’s largest textile producer and consumer. Cotton production involves the livelihood of 200 million cotton farmers and the employment of nearly 20 million textile workers, therefore, cotton plays a decisive role in the national economy of our country. However, with the development of cotton textile industry, at present, China’s cotton production is facing a serious shortage of gross and fiber quality problems. To increase the output of cotton and improve its quality is of great significance to increasing the income of cotton farmers and promoting the sustained and healthy development of China’s textile industry.
