我国农村稻草还田有着较长的历史,最早此项工作全靠人力或畜力来进行,由于手扶拖拉机的发展,现已逐步转向用机械在耕地作业时把秸秆埋入土壤中。目前,农村水稻秸秆还田的方法主要有以下几种。 (1)用手扶拖拉机及配套的旋耕机来实现。在耕作时,秸秆还田量约为30%～50%。由于手扶拖拉机旋耕作业时耕作层较浅,虽然大部分秸秆可以埋入土壤中,但尚有极少部分要露出地表面。此类方法虽然有缺 The straw in rural areas of our country has a long history. The earliest work depends entirely on human or animal power. Due to the development of walking tractors, straw has been gradually diverted into the soil by machinery when it is used for arable land. At present, there are mainly the following methods for returning rice straw to the countryside. (1) Use hand-held tractors and rotary tillage machines to achieve. In farming, the amount of straw returned to the field is about 30% ~ 50%.
