| Abstract: The field cultivation of Morchella spp. was greatly affected by the natural climate. In order to explore the suitable strains and light conditions for the indoor cultivation, Morchella spp. was cultivated by transport frames in the plastic greenhouse. The fruiting situation of Morchella sextelata, Morchella importuna, isolate strains No.1 and No.2 and the effects of different shading treatments on Morchella sextelata were studied. The results showed that the yield of Morchella sextelata was the highest, whose number and weight of fresh fruitbodies in each frame were 13.4 and 150.1 g respectively. Its merchandise properties of fresh fruitbodies were better, which showed concretely as follows: the shape of pileus looked like a spire, the fruitbody was dark gray and was moderate in size, the weight of each fresh fruitbody was 11.2 g, the length of stalk was shortest while the length of pileus was longest, the widest part of pileus was located in the joint of pileus and stalk. The comprehensive performances of Morchella importuna were inferior to Morchella sextelata but better than isolate strains No.1 and No.2. Morchella sextelata covered by 1 layer of shading net could normally fruit, while the treatments of no shading net and covering 2 layers of shading nets could not fruit normally. Therefore, the cultivation of Morchella spp. in the plastic greenhouse could choose Morchella sextelata and cover 1 layer of shading net to ensure the fruiting and yield. |
