Artificial culture method of perigord truffle strains

Abstract

The invention discloses an artificial culture method of black truffle strains, and belongs to the technical field of agriculture. The artificial culture method is characterized by including the following steps that 1, perigord truffle thallus solids are extracted and levigated into powder, namely sporophore; 2, a culture medium is prepared, wherein 40-50 parts of dry corn stalk residues, 20-30 parts of saw dust wood bit powder, 30-40 parts of grass cuttings, 20-30 parts of dry clay, 15-20 parts of fine sand and 8-10 parts of cow dung are mixed to be uniform, and a culture base stock is formed;3, a culture greenhouse is prepared; 4, infectious microbes in the culture medium are killed; 5, pond filling with the culture base stock and planting are carried out; 6, the growth period of the strains is managed, wherein growth of cucumbers on the upper portion of the culture medium is mainly managed, cucumber supports are built, and darkness and dampness of the culture base stock are kept; 7,fruiting time is managed, wherein the growth time of perigord truffle is 35-40 days optimally, at the moment, tender fruits of the cucumbers are borne, and the underground perigord truffle strains are dug out after the cucumbers are picked.
