Key points of summer management of bag-planted Lentinus edodes in spring
After the color conversion of Lentinus edodes in spring was over in mid-June, it entered the high temperature season. The mycelium of Lentinus edodes is not tolerant to high temperature and drought. When the temperature exceeds 35 ℃ and lasts for 4 hours, the mycelium begins to die and even melt itself. The following introduces the technical points to ensure the safety of bacterial bags in summer in production for mushroom farmers' reference:
1. Cool down. Shading, ventilation, sprinkling water on the ground, hanging clean wet sacks and other methods are adopted to reduce the temperature so that the temperature of the material does not exceed 30 ℃. Close doors and windows from 9: 00 to before sunset in summer to prevent hot air from entering the room.
two。 Sunshade. Thicken the sunshade layer to prevent the sun direct bacteria bag, avoid ultraviolet light to kill the mycelium or cause color conversion too deep, the skin is too thick.
3. Ventilation. The bacterial bag should not be too crowded or too high, leaving a gap between the bag and the bag, the heap and the heap, no more than 5 layers high, in order to facilitate heat dissipation and ventilation. Every day, in addition to the high temperature during the day to close the doors and windows, the rest of the time to maximize ventilation.

Tips for increasing production of Lentinus edodes planted in spring
Raise the temperature of Liu mushroom bed to create long mushroom conditions as the mushroom farm in early spring is still cold, it can be adjusted by natural temperature combined with artificial adjustment. The method is to cover the film tightly, increase the ground temperature, and dilute the sunshade on the shed surface on a sunny day, let the sun penetrate into the mushroom field, increase the heat source, increase the temperature of the mushroom bed, and keep the film cold at night. The temperature difference between day and night in early spring can promote the occurrence of mushroom buds. Beat the canister to promote the recovery of mycelium growth due to the cold climate in early spring, the mycelium is mostly dormant, no mushroom or rarely mushroom. Generally available racket

Processing points of export-oriented fresh-keeping Lentinus edodes
First, raw materials to choose fresh raw materials, the color should be normal. The shape of the mushroom should be complete, the stalk should be intact, and the mushroom body should maintain the beautiful shape of natural growth. The mushroom meat should be thick, the edge of the mushroom cover should be rolled neatly, the bacterial membrane should not be broken or slightly opened, and the umbrella should not be opened. The diameter of the mushroom cover is not less than 38 mm. Free from diseases and insect pests, odors and soil impurities. Raw material treatment and cold storage 1. Raw material pre-cooling and dehumidification in order to maintain good freshness and color of raw materials, fresh mushrooms should be pre-cooled in time after picking. Grasp the appropriate according to the performance of the equipment and the water content of fresh mushrooms.
