The invention discloses a method for cultivating tender ginger in deep furrows through deep ploughing. According to the method, adjustment and optimization are carried out in the process steps of selection and treatment of seed ginger, field selection, soil preparation, field planting, ridging, water and fertilizer management, pest control and the like. The method is mainly characterized in that deep-ploughing and deep-furrow cultivation is carried out, namely the field plots are ploughed deeply, bottom soil and surface soil are exchanged, the structure of the plough layer of soil is changed, and therefore plant diseases and insect pests, especially bacterial wilt, are avoided or reduced effectively. The seed ginger is planted in the deep furrows, and ridging and fertilization management are carried out three times. The method is scientific, standard and advanced. Practical application shows that when the method is used for cultivating the tender ginger, the plant diseases and insect pests are less, the yield is high, the cultivated tender ginger is white in pulp, fresh, tender, plump, good in commodity performance, good in quality, high in selling price and remarkable in benefit, and the tender stem is long. Through popularization of the method for cultivating the tender ginger in the deep furrows through deep ploughing, the yield and the quality of tender ginger products can be improved and guaranteed, and efficient development of the tender ginger industry is facilitated.
