Talking about the Storage and fresh-keeping of Mushroom
The main factors affecting the preservation of mushrooms are as follows:
Temperature: the higher the temperature, the worse the preservation of mushrooms. 0-4 ℃ is the suitable temperature for mushroom preservation. In addition to quick freezing, freezing injury is easy to be caused when the temperature is less than 0 ℃.
Water quality: when the content of iron or copper in the water is more than 2 mg / L, the mushroom color darkens and turns brown, so iron and copper utensils and tools are prohibited.
Humidity: 95-100% required. Less than 90% of the color darkens and it is easy to open an umbrella and deteriorate.
Gas composition: it contains important causes of decay, which can be inhibited by sterilization and adjusting pH value.
Enzyme activity: polyphenol oxidase is the main cause of mushroom browning.
1. Controlled atmosphere fresh-keeping: the mushrooms were treated with 0.05mm thick PE bag by special physical method. The results showed that the mushrooms were kept fresh and tender within 3-5 days by simple controlled atmosphere storage, and there was no browning, and the water loss rate was less than 1%. At present, the special physical fresh-keeping bag of Baileyuan mushroom with strong breathability is used to keep 1% oxygen concentration and 10-15% carbon dioxide concentration in the bag, which can keep the mushroom white within 5-8 days and have good freshness.
2. Cold storage: low temperature can keep mushrooms fresh and high quality. During the period of storage and transportation, it is most suitable to keep the temperature 0-3 ℃ and the relative humidity 90-95%. Packing with Baileyuan mushroom special fresh-keeping bag can also prolong the fresh-keeping period, keep fresh and tender and bright color.

Skillfully match the fertilizer of pollution-free mushrooms
1.1% or 2% soybean milk take 500-1000 grams of soybeans, soak and grind into milk, filter out impurities, add 50 kg of water and spray. It can make the mushroom white and tender, the stalk strong, and increase the yield by 8% to 15%. 2.0.3% 0.5% brine is added to 50 kg of clear water and 150 grams of 200 grams of salt is added, stirred and dissolved, and sprayed, which can make the mushroom color white, the mushroom stalk stout, and increase the yield by 12% to 17%. 3.0.02% 0.05% yeast powder add 25 grams of pure yeast powder to 50 kg of water, stir well and spray

Preparation and use of mushroom fertilizer topdressing solution
In order to increase the yield of mushrooms, fertilizer must be applied properly. According to practical experience, several preparation and application methods of mushroom topdressing solution are introduced as follows: 1. Mushroom root soup rinses the mushroom feet and crushed mushrooms cut during harvesting and processing, cut into thin slices, add 1 kilogram of water per kilogram of material, boil for 15 minutes, dilute the filter juice to 10 kilograms, spray mushroom bed 30 square meters. When used at the peak of mushroom production, the fruiting body can be thickened and the peak period of mushroom production can be prolonged. 2. Cattle and horses. Urine water extraction
