The results show that: Volvariella vol- vaceae is mushroom distinguished by its high rate of moisture (81% ± 0.530% fresh matter), high carbohydrate content (79.440% ± 0.24% dry matter) and protein content (17.010% ± 0.04% dry matter) very significant. Mineral composition contains more Na (1.880% ± 0.02% dry matter) and K (1.260% ± 0.12% dry matter). Seed of Irvingia gabonensis is rich in lipid (63.610% ± 0.70% dry matter) but it also contains appreciable levels of carbohydrates (23.250% ± 0.17% dry matter), protein (7.230% ± 0. 80% dry matter) and mineral matter (5.910% ± 0, 30% dry matter). These seeds of Irvingia gabonensis contain more K (0.678% ± 0.01% dry matter) and Ca (0.452% ± 0.09% dry matter). Seed of Beil- schmiedia mannii is rich in carbohydrates (92.080% ± 1.20% dry matter), and has a significant protein content (7.160% ± 0.11% dry matter), its mineral composition contains more than K (0.872% ± 0.05% dry matter).展开更多

It is also the most expensive mushroom in artificial mushrooms.With the development of economy and the industrialization of edible fungi, more and more straw mushroom has been cultivated in northern China, and southern mushroom is moving to northern areas. In this study, based on many years of cultivation experience, the high yield cultivating techniques of V. volvacea was summarized. V. volvacea cultivation consists of five steps, i.e.,composting, pasteurization, spawning, pining and harvesting.展开更多
