用带有小前犁的犁耕作,称复式犁耕法。我们垦区在五十年代初引进了这一耕作法,坚持了十几年,实践证明,复式犁耕法是一项科学的耕作方法。特别是用于草田轮作中的耕作,效果更好。使用这种方法,土垡翻转良好,杂草覆盖严密,土块破碎好,耕后地表平整。但是,近年来这种耕法逐渐被人们抛弃,小前犁被拆下丢弃不用,而采用不带小前犁的粗放耕作,这是不对的。建 Plow with small front plow, called double plowing. Our reclamation area introduced this tillage method in the early 1950s for more than a decade. Practice has proved that double plowing is a scientific farming method. Especially for the cultivation of grassland rotation, the better. Using this method, soil 垡 turn good, tight weeds, soil block is broken, surface roughness after plowing. However, in recent years, this farming method has been gradually abandoned by people. Small plows have been demolished and discarded. It is not appropriate to use extensive farming without a small front plow. build
