Research On Artificial Selection And High-yield Cultivation Technology Of Delicious Mushroom

Delicious mushroom is found in natural forest of a strain of wild large fungi, found only in the stipe, pileus not, have special seafood flavor, at present does not have the same repor t, The acute toxicity test,the actual non～toxic, Tasty, edible has the potential of artificial do mestication cultivation.The separation of "delicious mushroom" and edible value assessment study found,tissue isolation effect is best, mycelial colony morphology as white, thick, lacked aerial mycelium,c ulture appeared in the late period of primordium differentiation; aseptic skin phenomenon, the colony surface color is white; the colony back surface color is white, no secretion of pigmen t. The product of seed entities solitary or in groups, a number of1to4flower, flower ty pe is big, like a funnel; pileus brown, scaly, mature edge wavy, diameter of5.0cm～25.0cm, thickness1.0cm～2.4cm, bacteria, white meat, gill was born; stipe white-light bro wn, scaly Mao, the diameter of0.5cm～3.6cm,2.0cm-25.0cm length, dense texture. Th e fruiting body of dry goods have special seafood flavor.Delicious mushroom have17kind s of amino acids, which in addition to cystine than Panus giganteus identical amino acid content, other than the Panus giganteus delicious mushroom high, total amino acids reached145.5g/kg,33.6%higher than Panus giganteus108.9g/kg."Delicious mushroom" flavor a mino acid content is high, the content of glutamic acid was20.2g/kg,45.3%higher than t he Panus giganteus13.9g/kg, aspartate15.9g/kg than Panus giganteus10.3g/kg high54.4%, so "delicious mushroom" umami taste very good, rich flavor, taste more sweet, more nutri tious than Panus giganteus.Delicious mushroom crude protein contentthan the dried mushroom s21.2%,15.0%higher than1.8%, crude fat1.0%fewer mushrooms,mushroom flavor in the nu tritional value is higher than2times of mushrooms, mushroom umamiselenium content ofsele nium content of0.16g/100g,0.48g/100g near the mushrooms. Delicious mushroom in the m ain nutritional components, amino acid, crude polysaccharide, beneficial trace elements cont ent is much higher than with mushroom, with unique seafood flavor, bright spot, has a go od prospect of development and promotion.Study on the biological characteristics of delicious mushroom, culture temperature of25℃,the fastest growth rate, reaching7.58mm/d, and the incubation temperature20℃and30℃growth rate than reached the extremely significant level, the obvious advantage of growth. It is considered The cotton seed shellis appropriate use of sawdust, cultivation. The bacteria su itable growth was in the range of5-7in pH, partial acid type bacteria; the density is047kg/L, hypha sturdy, thick lines clear,glossy, mycelial growth rate were7.25mm/d; primordium nu mbe rare2-3respectively; the formation of flavor mushroom fruiting bodies need light stimul ation.12h the best effect of alternating light and dark.Umami mushroom primordia after furt her development, grow into fruiting body, artificial planting of success.Discovery of the study on high yield cultivation mode of flavor mushroom, the best cult ure medium formula is40%cotton seed hull,40%sawdust, wheat bran16%,2%CaO and2%CaCO3of the limelight calcium carbonate, water content65.0%. The optimum temperatur e of25～30℃for thebacteria, biological efficiency was70.4%;3main mode of cultivation, bi ological efficiency bag growth reached71.0%, significantly better than the other2kinds of e ffect. Soil thickness is3cm,the bud time is only3-7d, the biological efficiency of78.7%, the mushroom bud number1～2flower, the best effect. Successful development of this tasty mu shroom cultivation mode of high yield.Study on multi point regional tests find umami mushroom years, different test points at d ifferent time bag full of time in28-33d, there was no significant difference in different regio ns. The firsttide mushroom flower number in the1-2flower, the average yield of the first tid e in the111.9～126.1g/bag, the total average yield of120g/bag, the average yield of secon d tide in78.0Y105.1g/bag, the total average yield was89.4g/bag, second tide after the avera ge yield in64.3～94.5g/bags, the total average yield of74.2g/bag. The average yield of deli ciousmushroom271.3g/bag43.3g/bag higher than the control pork stomach mushroom228g/bag, a19%increase in production. The mycelium of strong resistance, such as encountered bad weather, winter or summer still can mushroom fruiting period, effective for the3season, in Fujian Province, mainly concentrated in the spring, fall fruiting. Different district pilot entitym orphological characteristics of no significant difference, diameter4.3-22.3cm, thickness1.0-2.8cm. Diameter0.4-3.8cm, length1.7～25.0cm. Pork stomach mushroom fruiting overall like ag oblet, gill involute; pileus after the mature edge does not appear wavy, this mushroom andflavo r in the shape of a significant difference. Umami mushroom at different sites did not differ significantly. Umami mushroom has the good social efficiency and economic benefits, suit able for cultivation in fujian province.To sum up, through this article research, Delicious mushroom artificial selection breed ing success, realize the cultivated mushroom, explore a set of Delicious mushroom cultivat ion mode of high yield, suitable for cultivation in fujian province, will be a new type edi ble fungus market increase, increase production of good for the mushroom varieties.
