What are the control methods for deformed mushrooms?
Deformed mushrooms mainly occur when ventilation is poor and the carbon dioxide content in the mushroom house exceeds 0.3%. Mushrooms that emerge too deep, growing out of cracks in the coarse soil, are also often deformed. For preventive measures, focus on ventilation and air exchange in the mushroom house. Ground bud mushrooms: when the compost is brought into the mushroom house with excessive moisture, when the mushroom house is ventilated too long during watering of the coarse soil, when the fine soil is covered too late, or when the temperature is relatively low, ground bud mushrooms are likely to appear. For preventive measures, master proper watering amounts and timely ventilation so that the mycelium hangs above the clay and below the fine soil.

How to Identify Mushroom Quality? Practical Identification Methods Taught to You
Mushrooms are a major category of edible fungi, divided into two types: wild mushrooms and artificially cultivated mushrooms. There are many kinds of wild mushrooms, and their shapes and species vary depending on the geographical environment and climatic conditions in which they grow. The variety of artificially cultivated mushrooms is increasing day by day. The most popular ones on the market include enoki mushrooms, shiitake mushrooms, oyster mushrooms, and phoenix-tail mushrooms. Good-quality edible mushrooms -- have the normal commercial appearance of edible mushrooms, with color matching their variety, normal odor, no off-flavors, pure variety, uniform size, and must not be mixed with non-edible fungi.

Mushroom High Yield: Top Dressing Is Key, Four Methods for Preparing Top Dressing Solutions
For mushrooms to achieve high yields, proper top dressing is key. Here are several methods for preparing mushroom top dressing solutions: 1. Mushroom root soup. Collect and wash the mushroom feet and broken mushrooms cut off during harvesting and processing, cut them into thin slices, add 1-1.5 kg of water per kg of material, boil for 15 minutes, take the filtered liquid and dilute with water to 10-15 kg, which can be sprayed on 30-40 sq m of mushroom beds. Using it during the peak fruiting period can make the mushroom fruiting bodies thick and plump and extend the peak fruiting period. 2. Cattle urine. Take fresh cattle urine, boil until the foam disappears, add clean water to dilute 7-8 times,

What are the new methods for high-temperature mushroom cultivation?
Mushrooms are tender and delicious, making them a traditional edible fungus variety that people generally love. However, the common mushroom variety is the button mushroom (Agaricus bisporus), with a fruiting temperature of around 16°C, coming to market in autumn, winter and early spring. The edible fungus technology extension station of Zhangjiagang City, Jiangsu Province, introduced and cultivated a high-temperature mushroom variety in 1998: the four-spored mushroom (Agaricus bisporus, four-spored type), with a fruiting temperature of 26-31°C; the fruiting bodies still grow well in July and August when temperatures reach as high as 26-38°C, and it can maintain continuous batch production capacity. The following is a brief introduction to high-temperature mushroom cultivation techniques.

What are the control methods for physiological diseases of mushrooms?
Hard opening of the cap: When mushrooms encounter abnormal weather, the phenomenon of young fruiting bodies opening their caps prematurely is called hard opening of the cap. It generally occurs at temperatures above 18°C, with a temperature difference of about 10°C, or under sudden temperature drops. Insulation work should be done well before sudden temperature changes, and the relative air humidity in the mushroom house should be increased. Malformed mushrooms: The causes of formation are uneven thickness of the casing soil, low fruiting position, and carbon dioxide content in the mushroom house exceeding 0.3%; or they are caused by pesticide damage, diseases, and insect pests. Attention should be paid to the quality of the casing soil and ventilation, preventing harmful gases from entering the mushroom house; attention should be paid to prevention

What are the green control methods for mushroom pests?
Today green food has become the mainstream of food, but in actual production, especially in autumn, mushroom farmers use large amounts of chemical drugs to control pests, which leaves large amounts of drug residues in mushroom products, planting hidden dangers for consumers' health and also blocking the path of mushroom products into the market, especially the international market. So how should pests be controlled in a "green" way? There are two measures: first, strengthen physical prevention. Measures include: mushroom sheds should be built far from stables and latrines, garbage, manure piles and other places, so that the environment has few or no insects; raw and auxiliary

What are the methods for keeping mushrooms fresh? Learn these tricks to store them longer
Storage and preservation of mushrooms 1. Kinetin preservation method. Soak fresh mushrooms in a 0.01% 6-aminopurine solution for 1015 minutes, take them out, drain them, and then store them. 2. Sodium metabisulfite treatment method. First rinse the mushrooms with a 0.01% sodium metabisulfite aqueous solution for 35 minutes, then soak them in 0.1% sodium metabisulfite for half an hour, take them out and drain them, put them into plastic bags for storage; the preservation effect is better under room temperature conditions of 1015°C.

Detailed Explanation of Mushroom Processing Methods and Technical Key Points
I. Pickled Mushrooms There are many methods for pickling mushrooms, including brine pickling, soybean paste pickling, and wine-lees pickling. 1. Brine pickling: The production process of brined mushrooms: fresh mushroom inspection → color-preservation treatment → rinsing → blanching → cooling → salting, sorting and packaging → adding brine. The color-preservation treatment is to prevent the fresh mushrooms from oxidizing and "browning". First, wash the fresh mushrooms with 0.05% sodium metabisulfite to remove impurities, then soak them for 5 minutes in a mixed color-preservation solution of 0.15% sodium metabisulfite and 0.1% citric acid. Then rinse with clean water

Six Major Mushroom Disease Prevention and Treatment Methods for Winter
Brown rot disease: When mushrooms are infected at a young stage, they cannot differentiate, and later form irregular grayish-white "lumpy heads," such as extremely thick caps resembling fists, or caps and stipes that are difficult to distinguish, with a layer of "white fuzz" growing on the surface. When the temperature is above 20°C, within 4-5 days the diseased mushrooms darken in color, then rot, exuding a brown, soy-sauce-like liquid, and rot and emit a foul odor; if the shed temperature is below 20°C, this process takes longer, requiring about 7 days or more. When fruiting bodies are infected at the mid-growth stage, brown lesions appear on the cap surface, the stipe becomes thick and swollen, and then the mushroom body

Causes and Control Methods of Deformed Mushrooms in Greenhouses
1. Hollow white-stem mushrooms. The mushroom stems become loose and white, and in severe cases shrink to form a hollow center. Causes: during the fruiting body growth stage, it is caused by dry air and high temperatures. When the relative air humidity is below 85%, the water content of the casing soil layer is relatively low, and the temperature inside the mushroom house is above 18°C, the mushrooms grow quickly and evaporate water quickly, causing the water absorbed by the mushroom body to be less than the water lost through transpiration. Control methods: spray water promptly during the day to keep the relative air humidity at 90%, and ventilate promptly after spraying water in the morning and evening to lower the greenhouse temperature, keeping it at 14-
