Description

The short breeding method of woodland microenvironment transformation of truffles
Technical field
The invention belongs to the cultivation field of planting of truffles, relate to the short breeding method of woodland microenvironment transformation of a kind of truffles.
Technical background
Truffles (Truffle), taxonomy is subordinate to Ascomycotina (Ascomycotina), Tuberale (Tuberales), Tuberaceae (Tuberaceae), Tuber (TuberMicheli:F.H.Wigg.).The business truffles of China is distributed mainly on the Sichuan of southwest, Yunnan Province, starts to develop at the mid-80, annual yield more than 150 ton, maximum output, 2002, about 300 tons.China is the maximum country of origin of natural business truffles, becomes second distribution center of world commerce truffles.
The growth of truffles must set up symbiosis with suitable host plant root system, and artificial culture truffles requires over mycorrhiza fungi seeding cultivating, then builds truffles woods and carries out.The domestic existing successfully report of cultivation of truffles, the cycle is generally required for 5-7, very very long.Domestic natural truffles since finding for 1985, it is progressively that place of production common people are cognitive, and sustainable exploitation utilization more than 20 year, owing to lacking relevant laws and regulations restriction, the collection of truffles fully belongs to unordered state, and the mode exploited is very original, boundless and indistinct aimless excavation, causes soil erosion, and the original excavation mode of rough predation formula causes that truffles resource and yield fall sharply, in recent years truffles producing region, all report resource is close to exhaustion.Therefore, the protectiveness collection of resource becomes the continuable key of truffles industry.
Summary of the invention
For the problems referred to above, inventor finds through long-term research, the growing point of truffles, temperature, illumination, humidity, water content are all very special, each truffles production is the result of natural selection, will not vary widely in a short time, usually not can produce continuously a lot of year when artificial destruction.Producing a little of artificial destruction, if recovered should be able to output truffles again in a short time, have not yet to see the report of the short propagating technology of woodland microenvironment transformation, the present invention proposes a kind of microenvironment transformation, and woodland urgees the method for numerous truffles.There is wide market prospect, the sustainable use exploitation of truffles resource is significant.
The present invention is achieved through the following technical solutions:
The short breeding method of woodland microenvironment transformation of truffles, after selecting collection truffles, the truffles through digging is produced a little, produce centered by host plant a little by this, in the scope that diameter is 1.0-1.5m, first root out the weeds on surface, as backfilling earthen backfill within the scope of this after then being smashed to pieces gently by the soil dug out.By backfilling after being smashed to pieces by the soil dug out, the strain being remaining in soil on the one hand is continued flourish, and being that surface soil maintenance is loose on the other hand improves breathability, also helps newborn truffles and grows, improves the lasting output capacity of truffles.
