棉花是技术性较强,用工较多的经济作物。从播种到拔柴,每亩需工约40—60个,其中田间管理用工约占三分之二左右。随着生产的发展,产量的提高和植棉面积的扩大,栽培技术有管理越来越细,投工越来越多的趋势。简化栽培技术程序,减少田间管理用工,是降低生产成本,提高经济效益的一个重要途径。 Cotton is a more technical and labor-intensive cash crop. From sowing to pulling firewood, about 40-60 mu are needed per mu, of which about two-thirds are field management workers. With the development of production, the increase of output and the expansion of cotton planting area, cultivation techniques have become increasingly finer in management and more and more in operation. Simplify the cultivation techniques and reduce field management labor is an important way to reduce production costs and improve economic efficiency.
