Mục tiêu của nghiên cứu là xác định phương pháp xếp mô và đốt áo mô đối với trồng nấm rơm ngoài trời. Thí nghiệm được bố trí khối hoàn toàn ngẫu nhiên với 05 lần lặp lại, mỗi lặp lại là 01 dòng dài 1,5 m. Các nghiệm thức (NT) gồm: NT1: Gối - Đốt áo mô, NT2: Cuộn - Đốt áo mô, NT3: Khuôn ngửa - Đốt áo mô, NT4: Khuôn úp - Đốt áo mô, NT5: Gối - Không đốt áo mô, NT6: Cuộn - Không đốt áo mô, NT7: Khuôn ngửa - Không đốt áo mô, NT8: Khuôn úp - Không đốt áo mô. Kết quả cho thấy nhiệt độ mô nấm ở giai đoạn ủ tơ và hình thành quả thể đều phù hợp với sinh trưởng và phát triển của nấm rơm. Chiều dài, chiều rộng của 30 quả thể xuất hiện đầu tiên và khối lượng trung bình/quả thể không bị ảnh hưởng bởi phương pháp xếp mô kết hợp đốt áo mô, hoặc không đốt áo mô. Xếp mô theo phương pháp cuộn và khuôn ngửa kết hợp đốt áo mô có thời gian xuất hiện quả thể sớm hơn so với các nghiệm thức tương ứng nhưng không đốt áo mô trong khi các phương pháp xếp mô kết hợp đốt rơm có thời gian kết thúc thu hoạch chậm hơn, ngoại trừ phương pháp xếp mô theo khuôn ngửa kết hợp đốt áo mô. Tổng khối lượng quả thể và số lượng quả thể/1,5 m mô của phương pháp xếp mô cuộn kết hợp đốt áo mô (2,82 kg và 339,8 quả thể) cao hơn tương ứng so với chỉ xếp mô cuộn (2,50 kg và 307,0 quả thể). ABSTRACT The objective of this study was to determine the proper bed design (BD) and burning of dry rice straw cover (BDRSC) to improve of rice straw mushroom (RSM) yield. A completely randomized block (CRB) experiment was carried out based on incubated rice straw bed under outdoor condition with 8 treatments and 5 replications, each replication as a row length of 1.5 m. The treatments included (1) Packing of rice straw (RS) - BDRSC, (2) Rolling of RS - BDRSC (3) Upward wood frame (UWF) containing RS - BDRSC, (4) Downward wood frame (DWF) containing RS- BDRSC, (5) Packing of RS– without BDRSC, (6) Rolling of RS - without BDRSC, (7) UWF - without BDRSC and (8) DWF - without BDRSC. The results showed that the temperature of bed met the demand of the growth and development of RSM. The length and width of the first 30 mushroom fruiting bodies (MFB) and mean weight per a MFB have not affected by bed types either BDRSC or without BDRSC. The BD as rolling of RS and UWF with BDRSC early produced MFB as compared to each corresponding treatment while BD with BDRSC expanded the harvest period, the exception for BD with UWF in combination with BDRSC. Total number of MFB and mean weight per 1.5 meter of rolling of RS incorporation of BDRSC (2.82 kg and 339.8 MFB) were higher than only rolling of RS (2.50 kg and 307.0 MFB), respectively.

The Impact

The research work was carried out to investigate the efficacy of different mother culture media viz., rice straw (T-1), rice straw and rice bran (T-2), rice husk (T-3), rice grain (T-4), maize grain (T-5), and rice straw and wheat bran (T-6) and the impact of age of mother culture and substrate sterilization techniques viz., sun dried for 8 hrs covering with transparent polythene (A-1), black polythene (A-2), blue polythene (A-3) sheet, autoclave for two hrs at 121°C (A-4), and hot water for one hr (A-5) for the commercial cultivation of Volvariella volvacea (Bull.) Singer. The maximum mycelium run rate and minimum days required for completing the mother culture were recorded in T-4. The lowest days required for primordial initiation (DRFPI) was 6 in T-1 and T-2, whereas highest DRFPI was recorded in T-3. The maximum (13.33) days required for first harvest (DRFFH) and lowest (109) number of effective fruiting bodies (NEFB) were recorded in T-3. The minimum (10.67 days) DRFFH was found in T-2 and maximum (239.30) NEFB was recorded in T-1. The lowest length and diameter (LFB and DFB) were recorded in T-5 (3.03 cm) and T-1 (1.66 cm), while highest LFB and DFB were observed in T-3 (3.20 and 2.39 cm). Maximum biological yield and efficiency were observed in rice straw and wheat bran materials. The highest NEFB, DFB, biological yield and efficiency were recorded in 30 days old of mother culture. The results revealed that combined rice straw and wheat bran were the excellent mother culture medium and 30 days old was the best age for the commercial production of paddy straw mushroom. Considering the experimental results on the sterilization techniques it may be suggested that hot water sterilization of rice straw substrate was the best sterilization technique for the commercial production and yield improvement of V. volvacea.

Although the button mushroom (Agaricus bisporus) accounts for slightly over half of total world mushroom production, specialty mushrooms, e.g., shiitake (Lentinula edodes), straw (Volvariella volvacea), oyster (Pleurotus spp.), and enokitake (Flammulina velutipes), are increasing in popularity. These species contain moderate quantities of good quality protein and are good sources of dietary fiber, vitamin C, B vitamins, and minerals. Lipid levels are low, but unsaturated to saturated fatty acid ratios are high (about 2.0 – 4.5:1). Some species (e.g., shiitake) accumulate cadmium and selenium and other heavy metals, and some may contain toxic substances such as the heat labile cardiotoxic proteins volvatoxin in the straw mushroom and flammutoxin in enokitake. Extensive clinical studies, primarily in Japan, have clearly demonstrated that a number of species have medicinal and therapeutic value, by injection or oral administration, in the prevention/treatment of cancer, viral diseases (influenza, polio), hypercholesterolemia, blood platelet aggregation, and hypertension. Most of the studies have focused on shiitake, enokitake, Pleurotus spp., and on the generally nonculinary Ganoderma spp. Many of the active substances which include polysaccharides (e.g., β-glucans), nucleic acid derivatives (the hypocholesterolemic eritadenine), lipids, peptides, proteins, and glycoproteins, have been isolated and identified. Some of the mechanisms of activity have been elucidated, e.g., antiviral activity via stimulation of interferon production in the host. Additional medical claims less well documented may nonetheless have some validity and merit further study.
