The invention discloses a cutting method for tobacco leaf section threshing redrying. According to the length of the tobacco leaves, a 0.618 golden section method is adopted for cutting the leaves into 11 to 20 sections from the leaf bases to the leaf tops, the leaves are respectively baked and crushed under the condition of 40 to 45 DEG C and are then sieved by a 60-mesh sieve to be made into samples, near infrared scanning is carried out under the wavelength condition being 4000 to 10000cm, and a near infrared map is obtained; the near infrared map data is subjected to second derivative solution, then, smoothing treatment is carried out, 4000 to 7600cm map regions are selected, and a principal component analysis-Mahalanobis distance (PCA-MD) method is adopted for clustering analysis; and the cutting dimensions of the section threshing redrying raw materials are finally determined according to the similarity degree of the near infrared map information of each section of samples through being combined with th
