1. manufacture a method for the blade root (116) of wind turbine blade (114), described wind turbine blade comprises blade root, stem portion (118) and leaf tip (120), and described method comprises:

  • Provide the skin (132) of reinforcing fibre, the wrought mat that this skin comprises at least two-layer reinforcing fibre;

    The internal layer (130) of reinforcing fibre is provided, and this internal layer has inner surface (150) and outer surface (152), and the wrought mat that comprises at least two-layer reinforcing fibre;

    At least two reinforcing fibre sections (134,136), the wrought mat that wherein each reinforcing fibre section comprises at least two-layer reinforcing fibre are set between described skin and internal layer;

    The pad (140) of the reinforcing fibre distributing is arbitrarily arranged between every pair of adjacent reinforcing fibre section;

    Polymer resin is incorporated in the blade root of wind turbine blade;

    The pad that sees through skin, internal layer, each reinforcing fibre section and the reinforcing fibre that each distributes arbitrarily carrys out resin by injection;

    AndMake hardening of resin to form the blade root of wind turbine blade.
