The invention belongs to the technical field of slope land agricultural cultivation and soil erosion prevention and in particular relates to a method for reducing water and soil loss of a downward grade ridge planting tobacco field. According to the method provided by the invention, ryegrass is planted in a matching manner on the basis of existing slope land downward grade ridging, direct scouring of rainwater on earth surface is reduced by virtue of fixation of a ryegrass root system on soil and water absorption and fertilizer absorption capability of the ryegrass, and runoff and sediment yield of the slope land tobacco field and N, P and K contents in the runoff can be greatly reduced. The method provided by the invention is used for conserving water and soil in the tobacco field and reducing N, P and K in the runoff. 本发明属于坡耕地农业耕作和土壤防侵蚀技术领域，具体涉及种降低顺坡垄作烟田水土流失的方法。本发明在现有的坡耕地顺坡起垄的基础上配种黑麦草，通过黑麦草根系对土壤的固定，以及自身吸水和吸肥能力，减少雨水对地表的直接冲刷，能够大大减少坡耕地烟田的径流量、产沙量以及径流中N、P、K含量。用于烟田水土保持和减少径流中N、P、K的方法。
