在丘陵沟垥区,红土新修梯田上采用“丰产沟”耕作法,既改良了土壤物理性状,加速土壤熟化,培肥土壤,又夺得当年粮食高产。是旱地梯田建立高产稳产田的重要途径。“丰产沟”耕作法可改造耕地面积的56%。具体做法是:开沟、深翻、客土、分层施肥,集中用肥,种 In the hilly gully area, newly planted terraces on the laterite use the method of “yielding ditches”, which not only improves soil physical properties, accelerates soil ripening, fertilizes the soil, but also wins the grain yield of that year. It is an important way to establish high and stable yield field in terraced fields. “Harvesting ditch” farming method can transform 56% of arable land. Specific practices are: ditching, deep plowing, guest soil, stratified fertilization, concentrated with fertilizer, species
