汉代是犁、锸农具并用时代。考古发掘所见两汉铁锸的形制,大致可分为两种:一为长方一字形平刃锸,一为凹字形铁刃锸,刃宽多为11—15厘米。铁锸的使用与铁犁牛耕的推广、江南的火耕水耨、沤田法、农田水利诸问题密切相关,只有综合考察铁锸与其它社会生产因素的相关关系和作用,才能对其做出客观的评价,简单地把铁锸与犁耕的翻地效率进行比较的研究,是不全面的。
Han Dynasty is a plow, 锸 farm tools and with the times. Archeological excavations seen Han dynasty iron 锸 shape, can be broadly divided into two types: one for the rectangular square 刃 flat blade 锸, a concave-shaped iron blade 锸, blade width of mostly 11-15 cm. The use of ferrola is closely related to the popularization of iron plowing, the cultivation of fermented pomfret in the south of Yangtze River, the law of field cultivation and the irrigation and water conservancy. Only by comprehensively examining the correlation and the role between ferrolata and other social factors of production can it be made Objectively evaluating and simply comparing the research on the turning efficiency of pumice with plowing is not comprehensive.
