The invention discloses a comprehensive determination method for gross cottonseed quality indexes. The method comprises the steps that screening and tabletting pretreating are conducted on gross cottonseeds, near-infrared spectrogram is scanned, spectral information is processed according to an optimal preprocessing method, and then the water content, the protein content, the oil content, the acid value, the kernel yield and the lint containing rate of the gross cottonseeds are quickly determined. According to the method, by conducting screening and extrusion pretreating on the gross cottonseeds, influences of impurities on the spectrum stability are reduced, obstruction of gross cottonseed lint on application of a near-infrared technology is overcome, therefore, modeling can be conducted on the gross cottonseeds by combining near-infrared scanning with a chemometrics multi-variate calibration method, and then the method through which various quality indexes of the gross cottonseeds can be determined is built
