The invention discloses a preparation method for a diamond cutter texture coating based on a micro-region blocking method. The preparation method is characterized by mainly comprising the steps that,1, a micro-hole and/or a micro-groove array are machined in a metal film to serve as a mask; 2, a tool base body undergoes pretreatment; 3, the mask is fixed on the surface of the cutter base body subjected to pretreatment; 4, a micro-region barrier film is deposited on the surface of the cutter covered with the mask by adopting a surface coating technology, the mask is removed after the film is prepared, micro-region protrusions with texture features and with the function of restraining the growth of a diamond are formed on the surface of the cutter; 5, a diamond texture coating is selectively grown on the surface of the cutter with the micro-region protrusions by adopting a CVD method; and 6, the micro-region protrusions which are formed on the surface of the cutter base body in a depositing mode and have the te
