How to carry out fog irrigation of Auricularia auricula

Black fungus is often eaten in our lives, especially agaric fried meat. I think many people have eaten it. Auricularia auricula has high nutritional value. Often eating Auricularia auricula is very helpful to reduce people's blood pressure and blood sugar, so middle-aged and elderly people can eat more fungus, which is very helpful to people's health.

What is black fungus?

Auricularia auricula, also known as black vegetable, mulberry, this fungus, tree chicken, wood moth, wood antler, because the shape is similar to the ear, coupled with its color dark brown named, Auricularia auricula for the Auricularia auricula family, its nature flat taste sweet, human stomach, large intestine meridian. It has the functions of nourishing, moistening dryness, nourishing blood and stomach, promoting blood circulation and stopping bleeding, moistening the lungs and intestines. Auricularia auricula is not only a kind of nutritious edible fungus, but also a traditional health food and export commodity in China. It has many aliases, because it grows on rotten wood, and its shape is similar to human ears, so it is called Auricularia auricula; it is also like a moth butterfly Yuli, also known as wooden moth; because it tastes like chicken, it is also known as tree chicken and wooden machine (the ancient Nanchu people call chicken as a machine): double auricularia auricula mosaic each other in the tree, like a piece of floating clouds, also known as cloud ear.

Morphological characteristics of Auricularia auricula

Auricularia auricula refers to the edible fungus of the genus Auricularia (scientific name: Auricularia or Wood ear), which is colloid in fruiting body, disk-shaped, irregular-shaped and 3-12 cm in diameter. Soft when fresh, horny when dry. It has many aliases, because it grows on rotten wood, and its shape is similar to human ears, so it is called Auricularia auricula; it is also like a moth butterfly Yuli, also known as wooden moth; because it tastes like chicken, it is also known as tree chicken and wooden machine (the ancient Nanchu people call chicken as a machine): double auricularia auricula mosaic each other in the tree, like a piece of floating clouds, also known as cloud ear. There are two main kinds of fungus that people often eat:

One is that the ventral surface is smooth and black, while the back is hairy gray or grayish brown, which is called Auricularia auricula, Auricularia auricula (commonly known as Auricularia auricula).

The other is smooth, dark brown and translucent on both sides, which is called black fungus, fine fungus and light fungus. Auricularia auricula has a large area, but its texture is tough, it is not easy to chew, it tastes bad and the price is low. Black wood ear soft taste, slippery and cool, rich in nutrition, is a kind of artificial cultivation, but also the main natural wild producing area Lushi County.

How to carry out fog irrigation of Auricularia auricula

Auricularia auricula is a medium-temperature fungus, mostly in late spring and early summer when the temperature reaches more than 20 ℃, so the demand for water is higher, and the relative humidity should be maintained at 85% Mel 90%. If the humidity is too low, it affects the formation of primordia and the development of fruiting bodies. However, too much watering can easily lead to ear bleeding and diseases. The practice shows that stable and high yield can be obtained by using fog irrigation to cultivate ears. The relevant technologies are introduced as follows.

The main contents are as follows: 1. The fog irrigation facility is composed of dry, branch and wool high-pressure polyethylene plastic pipe miniature atomization sprinklers and pipe fittings. The diameter of the main pipe is 40 Mel 50 mm, the diameter of the branch pipe is 25 mi 32 mm, and the diameter of the capillary is 10 mi 12 mm. During installation, the water source of the main pipe is perpendicular to the branch pipe, the branch pipe is perpendicular to each ear trunk, and the capillary (usually 15 meters long) is parallel to each ear trunk and is suspended above it. Atomization nozzles are 1.5 meters apart and are installed on the same side of the capillary (facing the dry ear). When spraying, the dry ear receives water evenly.

2. Key points of fog irrigation technology.

① fog irrigation time every spring is the golden season for cultivating Auricularia auricula. At this time, fog irrigation can increase the yield of Auricularia auricula by more than 80% of the total yield. Therefore, May to June should be regarded as the key period for fog irrigation to increase production. If there is no high temperature (below 30 ℃) in July, if we insist on fog irrigation to cool and humidify, we can also harvest 1 Mel and 2 damp ears.

The fog irrigation time of ② should be more than 0.5 hours and less than 2 hours. The duration of fog irrigation is closely related to the dry and wet weather, temperature, dry ear water content and other conditions. If the weather is dry, the temperature is high, and the water content of the ear stem is low, the fog irrigation time can be appropriately prolonged, otherwise, the fog irrigation time can be appropriately shortened. When the water content is close to the lower limit of water content suitable for ear base growth (about 50%), there is mycelium growth and fruiting body development.

For ③ fog irrigation, intermittent water supply is suitable for ear stem in the early stage, the water absorption rate is faster, the water utilization rate is high, each fog irrigation should not be less than 0.5h, and the interval between two irrigation should be about 0.5h. In the middle and later stage, the interval of irrigation can be lengthened properly (1-1.5 hours).

In this way, it can not only save water, but also improve the utilization rate of water, make the relative humidity of ear field suitable, avoid diseases and insect pests caused by excessive humidity, and be beneficial to the growth of ear slices.

The fog irrigation of ④ factory ear cultivation requires factory ear cultivation. If there are temperature control facilities, it can be carried out all the year round. Industrial cultivation mainly uses substitutes (bagged sawdust, cottonseed shell, etc.) to cultivate ears. During the ear discharge period of the bag discharge (code into a wall), fog is applied once every 3 hours during the day, each time for 0.5 hours. The room temperature is generally maintained at 20 ℃, and the air humidity is maintained at 80%. 90%. If there is a high temperature (more than 28 ℃), fog irrigation should be added at noon to cool down and increase the temperature, which is beneficial to the growth and development of auricularia fruiting body.

As people know more and more about Auricularia auricula, so now there are many people in the market who begin to plant Auricularia auricula. The cultivation of Auricularia auricula also needs to pay attention to certain techniques and skills. Some people can get good income, while others do nothing.
