Why do twisted mushrooms appear and how to prevent them?
The main symptom of twisted mushrooms is that the stalk elongates spirally, and the broken stalk changes from a cylinder to a flat strip. Mushroom farmers call it "sesame mushroom". Although it is edible, it does not meet the standard of canning. Twisted mushrooms usually occur sporadically in mushroom clumps. In addition to being related to the cultivated varieties, the young mushroom is not strong, the mushroom cluster is too dense, the growth space is insufficient, the light direction is changeable and so on, which will cause the stalk to be twisted too much. The way to prevent it is to sparse the cultivation bag, do not move the bag (bottle) of the long fruit body casually.

The site and method of mushroom production should be selected.
Bag cultivation of Pleurotus ostreatus in mushroom field can be carried out indoors or outdoors. Indoor mushroom production: generally, you can use spare houses to produce mushrooms, and you are required to choose rooms with good air permeability, good heat preservation and moisturizing properties, and sufficient light, preferably a room facing south. Outdoor mushroom production: generally, the above-ground or semi-underground plastic shed is used for mushroom production, especially the semi-underground plastic shed, because the semi-underground plastic shed has good heat preservation and moisturizing performance, which is conducive to the formation and growth of fruit bodies. The semi-underground plastic shed is as deep as

Causes and control of death of mushroom buds and young mushrooms
1. Excessive temperature when the mushroom buds form and grow, the temperature of the mushroom shed (room) suddenly rises or is above 20 ℃ for several consecutive days, coupled with poor ventilation, the mushroom buds will atrophy and turn yellow, and finally die. This often happens in late autumn or early spring, because the mushroom bud is formed at low temperature, and its nutrition is transported from the hyphae to the fruiting body, and when the temperature suddenly rises, the nutrition flows back from the fruiting body to the mycelium, and the mushroom bud dies because it does not get nutrition. Prevention and control method: pay close attention to the change of temperature and adjust according to the weather forecast

What are the reasons for the deterioration of salted mushrooms and their control measures
During the curing process, if the film and fungus flower appear, it indicates that the surface is contaminated with yeast or mold, which can make the tissue soft, lose its gel and cause spoilage. If contaminated by rotten bacteria, protein and amino acids can be decomposed into indole, hydrogen sulfide, etc., which will produce odor and other toxic substances. Reasons for deterioration: (1) Low salt concentration or high pH value: General salt solution requires salinity above 22 Baume degrees, pH value between 4 and 5, and should be adjusted in time during the curing process.

Common Species and Control of Deformed Mushrooms
Deformed mushrooms have various forms of expression, the main common ones in production are: mine mushroom, hollow mushroom, big ass mushroom, hard umbrella and early umbrella, red root, rust spot. Mine mushroom. The main reasons are that the covering soil material is too coarse, the soil is hard, the covering soil is thick, the surface water content of the covering soil is less, and the temperature and humidity conditions of the lower part and the base material are suitable for the occurrence and growth of the fruiting body, so it is easy to differentiate into the fruiting body on the material surface or the lower layer of the covering soil, and then drill out of the soil surface. Solution: Select high-quality humus soil, preferably grass

Cultivation techniques of Pleurotus ostreatus
Pleurotus ostreatus, with delicious taste, crisp and tender texture and rich in protein and amino acids, is one of the most popular edible mushrooms in Europe and Southeast Asia. Requirements for cultivation environment 1. Nutritious Pleurotus ostreatus is a kind of wood-rot fungus, the nutrients needed for its growth and development are mainly carbon and nitrogen sources, suitable carbon sources are sawdust and cottonseed hull, and suitable nitrogen sources are corn meal, soybean cake powder, wheat bran and rice bran. Mycelia grow on PDA medium, or wheat seeds, or liquid bacteria are attached to sawdust, sawdust plus cottonseed hull or pure cottonseed hull.

Organic cultivation techniques of Pleurotus ferulae
In the cultivation season, the optimum temperature for the growth of Pleurotus ferulae mycelium was 5 ℃ ~ 32 ℃, but it grew fastest at the temperature of 25 ℃, and the best temperature for fruiting body growth was 8 ℃ ~ 15 ℃. When cultivating Pleurotus ferulae, the mushroom bag is usually made from September to October, and the mushroom production management is carried out from November to April of the following year. Cultivation places and cultivation methods: the cultivation sites can be used as idle houses in rural areas (which must be renovated). If underground projects (civil air defense tunnels, national defense projects, basements) are equipped with light sources and ventilation facilities, they can also be used as cultivation sites. Pleurotus ferulae is molded

A New Formula for Fast growth and High yield of Pleurotus ostreatus
Tea mushroom, also known as tea tree mushroom, is a rare delicious health food, which sells well in the market. at present, the price of fresh mushroom is up to 20 yuan / kg. At present, the yield of artificial cultivation of Pleurotus ostreatus is low, which is mainly controlled by the strain and the formula of cultivation materials. The new formulations of several ideal cultivation materials are introduced as follows: 1. Tea shell powder 70%, rice bran 20%, tea meal powder 5%, sucrose 2%, lime 1%, gypsum 1%, potassium dihydrogen phosphate 1%. Take the dry material according to the formula ratio, the ratio of material to water is 1 ∶ 1.25, mix well.

Pleurotus ostreatus
Symptoms: mushroom stalk tissue is not full, there is a white loose pulp inside, the pulp shrinks or falls off into a hollow shape after drying or cooking. The cause: it is mainly due to improper water management. if the air humidity of the mushroom room is low, the soil layer humidity is low, especially the water content of the coarse soil layer is insufficient, the rapidly growing fruiting body will not be able to get sufficient water from the soil layer. furthermore, the transport and supply of nutrients will be reduced, coupled with the continuous evaporation of water in the mushroom body, which will result in a lack of water in the middle of the stalk and a lack of tissue.
