中国是产棉大国,2011年中国棉花种植面积504万hm~2,棉花产量660万t,占世界近30%,新疆棉花种植面积146万hm~2,棉花产量250万t,棉花产量占到全世界的1/9,全国产量的1/3以上。随着近年来劳动力价格的不断攀升,棉花机械采收已成为市场的选择、农民的期盼,以沙湾、乌苏一带为例,机采2925元/hm~2(首次采收1 875元/h m~2,复采1 050元/hm~2),而人工采摘费用平均2.3元/kg,扣除机采棉收购价格低于人工采棉价格的因素,减少采收成本2250元/hm~2,还不包括人员管理的费用,而且采用机械采收可以将人们从长时间繁重的体力劳动中解放出来,且节省了采收时间。近几年,由于拾花工难找,管理成本增加,机械采收已经
China is a big cotton producing country. In 2011, the cotton acreage in China was 5.04 million hm 2, the cotton output was 6.6 million tons, accounting for nearly 30% of the world’s total. Xinjiang’s cotton acreage was 1.46 million hm 2 and its cotton output was 2.5 million tons. 1/9 of the world and 1/3 of the national output. With the rising labor prices in recent years, cotton mechanical harvesting has become the market choice, farmers look forward to the sand Bay, Wusu area, for example, mining 2925 yuan / hm ~ 2 (the first acquisition of 1875 yuan / hm ~ 2, compound recovery of 1 050 yuan / hm ~ 2), while the cost of artificial picking is 2.3 yuan / kg on average, deducting the purchase price of cotton picking machine is lower than the price of artificial cotton picking, reducing the recovery cost of 2250 yuan / hm ~ 2, does not include personnel management costs, and the use of mechanical harvesting can be people from a long period of heavy manual labor liberation, and save the harvest time. In recent years, due to hard to find pick-up workers, management costs increase, mechanical harvesting has been
