The invention discloses a Chinese orchid biological activity graft material and process for preparation which comprises the procedures that firstly, ultra-fine tourmaline, medical stone, na-activationmontmorillonite and vermiculite are mixed according to the weight ratios of 1:2-4:2-3:3-5, are filled with water and churned to be even, and are positioned in a shaping machine to be pressed and shaped, and particles are made in a disk-style particles-making machine to manufacture active material ball-shaped particles of which the diameter is 0.5-1cm, secondly, graft inscriptions 30%-50%, granuleimmortal soil 30%-50% and active material 5%-20% are mixed to prepare biological activity graft material. The invention has the advantages of excellent air permeability, and cleaning and hygiene andthe like, and the immortal soil can make up the shortcoming that graft inscriptions do not contain fertilizer, and the most outstanding is that active material can activate water mass and promote growth of Chinese orchid, and mineral element which is dissolved out can be further supplied for the growth of Chinese orchid. Granule graft materials and active substances are scientifically matched, which lead various substance performances to reach the best state and are convenient for being managed in daily life, and the invention is particularly applicable to indoor places or places in which environmental hygiene requirements are relatively high.
