The invention discloses a peanut leaf organization grinding system for extracting DNA, and belongs to the technical field of biotechnology. The peanut leaf organization grinding system comprises an alcohol lamp, a centrifugal tube, a liquid relief gun head and a liquid nitrogen, wherein a small end of the liquid relief gun head is provided with a circular ball after being heated and melted by the alcohol lamp; the centrifugal tube comprises a columnar section and a conical section, and the minimum diameter of the conical section is more than the diameter of the circular ball; the length of centrifugal tube is less than that of the liquid relief gun head; the circular ball formed by heating and melting the small end of the liquid relief gun head by the alcohol lamp is matched with the existing centrifugal tube; the peanut leaf organization after being cooled by the liquid nitrogen is smashed so as to directly extract DNA in the peanut leaf organization after smashing in the centrifugal tube; compared with the
