The Study Of Industrial Cultivation Of Tremella Fuciformis

Tremella fuciformis was a well-known medicinal and edible fungi.The technology of cultivating Flammulina velutipes and Pleurotus eryngii in a factory farm has already been quite mature in recent years. Tremella fuciformis was still using the traditional cultivation mode, so to explore the method of cultivating Tremella fuciformis in a factory farm has very important practical significance. In this experiment, choose the most suitable spawn for factory cultivating, optimization on the preparation technology of original spawn, cultivating medium and production technology. The result provided theoretical basis for factory cultivation. The results were as follows:1. Through the experiment of the growth characteristics and fruit body morphology characteristic in the six spawns, we find the most suitable spawn for factory cultivatiing:Tr 21.2. Through the optimization on substrates formula, the ratio of Tremella fuciformis spawn and xianghui spawn,the influence of different age on the production. The results shown that the best substrates formula was cottonseed hull 75%. bran 20%, gypsum powder 2%, phosphate 3%. Medium is bottled at two levels, mixed two-thirds of medium at the bottom of the bottle with sugar water,keeping the water content 65%, mixed the rest of the culture medium with water,,keeping the water content 60%; The best ratio of Tremella fuciformis spawn and xianghui spawn was 1:2; The best age for Tremella fuciformis production was six days.3. Through the single factors and orthogonal test of culture medium formula. The results shown that the best main material was cottonseed hull,the best accessories was bran,the best nutrient solution was 1: 1.3.4. The results shown that the best medium formula, Cottonseed hull 80%, Bran 18%, Gypsum powder 1%, Phosphate 1%, Liquid ratio 1:1.3. The best cultivating conditions:cultivating material content 650g,temperature 24℃, air relative humidity 85%,pH 6.5-7.0. The best time for lifting the rubberized fabric a corner was on the tenth day after inoculation, the best way to keep humidity was using the spray humidifier.5. Using factory cultivation, the growth cycle was only 35 d, Shortening 5 d than the traditional seasonal cultivation. The yield improved 33.3%,,break through the traditional way of relying on natural conditions.
