Key Technical Points for the Early-Stage Operation of Edible Mushroom Growing Substrate
Preparing a good edible mushroom growing substrate is very important, as it directly affects the growth of the edible mushrooms and the grower's returns. Here I will use the preparation of growing substrate with Jinbaobei fermentation agent as an example to introduce the key operating points. 1. Material preparation: Prepare Jinbaobei edible mushroom substrate fermentation aid at 0.1% of the substrate weight (that is, one part per thousand; if discarded substrate is being reused, it may be added at 0.2%); pre-soak or rinse the crushed or cut main material in advance to pre-wet it, and adjust the moisture to 60-70% and the pH to about 8. If the moisture is too low, it is not conducive to the rapid reproduction of functional microorganisms,

What measures can prevent contamination of the substrate bags for tea tree mushroom cultivation
Contaminant organisms can appear during the cultivation of the tea tree mushroom (Agrocybe aegerita), and the following measures should be taken to prevent contamination of the substrate bags. First, add water to the cottonseed hulls 24 hours in advance and pile them for fermentation, raising the substrate temperature to 60-70°C to kill contaminant organisms. Second, after adding wheat bran to the ingredients, the time from mixing the substrate and filling the bags to placing them on the stove for sterilization must not exceed 6 hours, to prevent the substrate from souring. Third, during sterilization, maintain the temperature above 100°C for 24 hours, without letting the fire go out, adding cold water, or letting the temperature drop, so as to achieve thorough sterilization. Fourth, when moving the substrate bags after sterilization, handle them gently to prevent the bags from being damaged.

What are the control measures for the difficulty of shiitake mushrooms fruiting in bag substrate
In recent years, the "Xixia model" of cultivating flower shiitake mushrooms on plastic racks with bag substrate as the main body has become a model for the south-to-north migration of mushrooms in China, blooming all over the country. However, due to regional climate temperature differences and the fact that mushroom farmers in newly developed areas have little understanding of shiitake mushroom variety types and fruiting characteristics, they used medium-temperature shiitake varieties such as 135, 241, 939, L26, etc., or similar strains, and when forcing fruiting in low-temperature seasons, the abnormal phenomenon of being unable to fruit normally after forcing occurs, resulting in reduced yield in mild cases and loss of capital in severe cases. Now we present our control measures for bag substrate

Detailed Guide to Preparing Wheat Grain Substrate
Formula and treatment: 100 kg wheat grain, 10-20 kg dried stored fermented manure-straw or rice husk. 1-2 kg calcium carbonate or gypsum powder. Wheat grain is rich in nutrients and promotes vigorous mycelial growth. To prevent premature decline of mycelial vigor, add 50 g magnesium sulfate and 100 g monopotassium phosphate per 100 kg wheat grain for better results. Choose wheat grains that are plump with thick hulls and free of insect damage or broken grains. Generally, aged wheat that has undergone a dormancy period gives better soaking results, absorbing water and softening quickly. Soak the wheat grains in 1%-2% lime water, with the water level higher

Detailed Explanation of Points to Note When Mixing Substrate for Substitute-Material Cultivation of Shiitake Mushrooms
Substitute-material cultivation of shiitake mushrooms is another cultivation method following log or round-wood cultivation. Its cultivation forms are diverse, mainly designed according to differences in cultivation conditions, cultivation materials and cultivation containers. It has developed rapidly in recent years and now accounts for more than 95% of the cultivation area. In its medium, materials rich in cellulose, lignin and hemicellulose, such as wood chips, crop straw and wild grasses, are used as the main components of the cultivation material, appropriately supplemented with auxiliary materials such as wheat bran and rice bran rich in organic matter and vitamins, as well as gypsum, calcium carbonate and similar substances containing inorganic salts. The water content is adjusted to around 60%, and after sterilization it is inoculated and cultivated.

Key Technical Points for Winter Management of Lentinula edodes (Shiitake) Cultivation on Substitute Substrate
After the onset of winter, temperatures drop and relative air humidity is low, so management should center on raising the bed temperature, controlling ventilation, and keeping warm and protecting against cold. Corresponding management measures should be taken for different strains. For medium- and high-temperature-type strains, there is almost no hope of further fruiting below 10°C; at this time, water should be sprayed in the afternoon each day along with brief ventilation, just keeping the logs moist so they can overwinter smoothly. For medium-temperature-type or slightly lower-medium-temperature-type strains, there is still hope of fruiting in provinces where winter is not pronounced. Based on weather forecasts, cold waves can be avoided, and the brief periods when temperatures rise can be used

Harvesting, Processing and Storage Methods for Shiitake Mushrooms Cultivated on Substitute Substrate
(1) Harvesting time The time required from the appearance of mushroom buds to harvest varies with temperature and humidity; generally it takes 7-10 days from budding to maturity. Timely harvesting is an important part of shiitake cultivation, as harvesting too late or too early will affect both yield and quality. The harvesting stage should also be determined according to whether the mushrooms are sold fresh or dried. Generally, for dried mushroom sales and fresh mushrooms for the domestic market, it is best to harvest when the fruiting bodies are 60-80% mature, that is, when the veil has already broken and the cap still curls inward slightly; at this stage the quality is good and the value is high. When fresh mushrooms are for export

Detailed Explanation of Key Points of Mixing Substrate for Substitute Material Cultivation of Shiitake Mushrooms
Weigh according to the proportion requirements of various raw and auxiliary materials and water in the formula. Specific operation method: spread the weighed raw materials such as sawdust and cottonseed hulls flat on the cement floor, pile them into a small hill shape, then evenly sprinkle bran, gypsum powder, etc. on top, mix repeatedly and evenly with a hoe or shovel, and make a pile with a concave middle. Add the pre-dissolved white sugar, potassium dihydrogen phosphate, etc. to an appropriate amount of clean water, mix well, and splash it onto the material. Mix several times with a shovel and broom so that various raw materials and water are stirred evenly, then bag and make sticks. When making mushroom sticks, according to the raw materials

Detailed Explanation of Key Points of Lentinula edodes (Shiitake) Substrate Cultivation Techniques
1. Production season arrangement. The season for shade-shed open-field cultivation must be arranged according to local climatic conditions, altitude and varietal characteristics. In Zhejiang Province, the shade-shed open-field cultivation season is generally arranged from mid-to-late August to September to early October for loading substrate and inoculation, and from mid-to-late October to early May of the following year for fruiting. 2. Varieties. The shiitake varieties suitable for shade-shed open-field cultivation are mainly medium-temperature-type shiitake strains, such as the CR series and the Shenxiang series. 3. Culture medium formulas. Formula 1: miscellaneous wood sawdust 78%, wheat bran 20%, sugar 1%, gypsum

Detailed Explanation of Key Points in Shiitake Mushroom Substrate Cultivation Techniques
Shiitake mushroom substrate cultivation, also known as substitute substrate cultivation, is another cultivation method following log or natural log cultivation. Its cultivation forms are diverse, mainly designed according to differences in cultivation conditions, cultivation materials, and cultivation containers. It has developed rapidly in recent years and now accounts for over 95% of the cultivation area. Based on different cultivation methods, it can be divided into pressed-block and bag cultivation; based on different cultivation sites, it can be divided into mushroom house cultivation, underground facility cultivation, greenhouse cultivation, sunken bed cultivation, woodland cultivation, etc. 1.
