Six methods of saving cost and increasing efficiency of edible fungi

1. The temperature difference stimulation method adopts the measures of heating up the bacteria bed by covering the film in the daytime and removing the film in the evening or in the morning to cool down. The air relative humidity was controlled below 70% in the early stage of mycelial growth and kept at 85%-90% in the later stage. These measures are beneficial to the formation of mushroom buds.

two。 When the culture material was prepared by drug stimulation method, the yield was obviously increased by adding phosphate (potassium dihydrogen phosphate, calcium superphosphate), sulfate (magnesium sulfate, calcium sulfate) and vitamin B1. In the later stage of mycelial growth, spraying 0.1 mg / L ~ 0.2 mg / L triacontanol on the culture surface can promote mycelium growth and mushroom production, and increase the yield by 10% to 15%.

3. Scratching method when the hyphae grow all over the culture surface, gently sweep the material surface with a clean bamboo broom to remove or destroy the overgrown hyphae and old hyphae on the surface. Spray water after exposing the new mycelium, cover the film to keep warm and moisturize, and the mushroom can appear in about 7 days. Generally speaking, it can increase production by about 10%.

4. Shock bacteria method when the culture material is full of mycelium, squeeze and beat the vibrating material surface with a strong elastic lath. When operating, the force should be uniform, do not leave deep marks, do not destroy the material surface. This can promote the accelerated growth of hyphae and the rapid differentiation of seed bodies. This method is suitable for Lentinus edodes, Pleurotus ostreatus, Pleurotus ostreatus and Auricularia auricula, and can generally improve the biological efficiency by about 15%.

5. The contact method covers the culture surface with old newspapers, sacks and fine soil, which can promote the rapid growth of mycelium by pressure stimulation. Or a sterilized stick (1 cm in diameter and 3 cm in length) is inserted into the material about 2 cm deep, and the hole density is about 15 cm × 15 cm, so that when the mycelium grows and spreads, it touches the stick and winds around it to form a uniform and dense mycelium, which develops to form mushroom buds and seed entities, which can generally increase production by about 20%.

6. The hole filling sand method can improve the air permeability of the mushroom bed, improve the water retention of the material surface, and make the mushroom on the culture material surface uniform, big and thick. The method is: when sowing, a conical stick with a diameter of 1.5 cm and a length of 30 cm is used to make a hole in the shape of a plum blossom according to the specification of 30 cm in plant and row spacing, and the hole is deep to the bottom of the material. Two days later, the hole is filled with yellow sand (the sand is to be soaked and disinfected with 1% potassium permanganate solution). The yellow sand should be 0.5 cm ~ 1 cm higher than the material surface, and 0.3% 0.5% lime water should be injected into the hole at the same time. By using this method, the mushroom can be produced 3 ~ 4 days in advance, and the mushroom can be evenly distributed and hypertrophic. The biological efficiency of Pleurotus ostreatus can be increased by 28%.
