我国是世界上最大的棉花生产和消费国,棉花面积占种植业的3%,产值达10%。近10年来,我国棉花面积从8 889万亩下降到不足7 000万亩,下降趋势明显。特别是黄河流域,棉花面积从3 864万亩减少至2918万亩,年均减少157万亩。下降的主要原因是棉花生产周期长、环节多、机械化水平低,用工多且作业环境艰苦。棉花生产全程机械化是根本出路,机械采 China is the largest producer and consumer of cotton in the world. Its cotton area accounts for 3% of the planting industry and its output value reaches 10%. In the past 10 years, the cotton area in our country dropped from 88.89 million mu to less than 70 million mu, a clear downward trend. In the Yellow River basin in particular, the area of ​​cotton decreased from 38.46 million mu to 29.18 million mu, with an average annual decrease of 157 million mu. The main reason for the decline is the long cycle of cotton production, the high number of links, the low level of mechanization, the heavy labor and the difficult operating environment. Mechanization of cotton production is the fundamental way out, mechanical mining
