What are the planting techniques of Morchella? How to choose? Do you need to control the lighting?

Morchella is a precious variety of edible fungi, which is generally planted and cultivated in Xizang, Yunnan, Xinjiang and other areas of our country. Morchella, also known as Phyllostachys pubescens, has high nutritional value. So do you know the planting technology of Morchella? How to choose Morchella? What are the areas of distribution?

1. Planting techniques of Morchella

1. The sowing time of Morchella is generally from October to December every year, and the hyphae can grow from 3 degrees Celsius to 25 degrees Celsius, and the most suitable temperature is 15 to 18 degrees Celsius, below 3 degrees Celsius or above 25 degrees Celsius mycelium growth stops or dies. The seeding rate of bacteria is 200 kg per mu. When sowing, the bacteria should be scattered evenly and accurately on the culture material. After sowing the bacteria, the soil can be covered with a thickness of 3m / m. After the covering is over, it can be watered. The hyphae are required to grow in a moist environment, and the relative water content of the soil is controlled at 50% and 70%.

2. The growth of Morchella mycelium should be protected from light and moisturizing, while the growth of fruiting body should be protected by weak light, too strong light or insufficient humidity are not conducive to the growth of mycelium and fruiting body, so it is necessary to build artificial awning, which is divided into flat shed and arch shed.

3. The first is temperature control, because of the large temperature difference between day and night in spring, it is beneficial to promote the growth of fruiting body. Not only that, the suitable temperature and precipitation in early spring provide good conditions for the germination and growth of fruiting body of Morchella esculenta. The fruiting body can grow from 10 degrees Celsius to 18 degrees Celsius, and the most suitable growth temperature is from 12 degrees Celsius to 15 degrees Celsius. The growth of the fruiting body slows down when the temperature is below 10 degrees Celsius or above 18 degrees Celsius. The fruiting bodies of Herba Euphorbiae growing in the flat shed were unearthed quickly because of good air circulation.

4. In the aspect of light, light can promote the formation of fruiting body to a certain extent, especially in the development stage of fruiting body, light plays an important role. During the growth and development of fruiting body, moderate scattered light is an indispensable condition for the production of high quality Morchella. The fruiting body of sheep liver fungus has directional light and often bends and grows in the direction of light.

The intensity of scattered light also has a certain influence on the color of the fruiting body, the stronger the light is, the darker the color is, and the weaker the light is, the lighter the color is. It is most appropriate to control the light at three parts of yang and seven parts of yin in the mushroom period.

5. At the stage of mushroom emergence, the relative water content of the soil should be controlled at 50% Murray 70%, so that Morchella can grow smoothly. In management, we should pay attention to control two extreme humidity: one is that the air relative humidity is not less than 70%. If the air humidity is low, the middle of the fruiting body is empty, and the weight is light, the skin is thin, and it is easy to dry and crack, causing the fruiting body to stop growing. For this reason, to maintain a humid environment, spray is used once or twice a day, and when spraying water, let the water spray drip to the ground. Second, the relative humidity of the air is not more than 90%, and the relative humidity of the air will cause hypoxia in the fruiting body. In short, the requirement of spraying water is a small number of times.

6. When the cover surface of the Morchella fruiting body is fully extended, showing a belly-shaped pit, it can be harvested, but some of the Morchella fruiting body is solitary, some are symbiotic, and the whole growth process has irregular continuity, so it should be picked along with the growth. to ensure freshness, at the same time of harvest, as there are many fruiting bodies sprouting or unearthed to grow, be careful not to damage the growing fruiting bodies.

7. Insert small pieces of bamboo into the soil during harvest, then gently pry up until the Morchella is loose.

Second, how to choose Morchella?

1. Morchella is a very precious wild fungus. The choice of Morchella is generally based on a large one, and the dome is the top grade, which is the wild Morchella. The spire is mostly planted, and the fragrance of thin meat is not strong. Therefore, the second place.

2. The color of wild Morchella is not uniform, such as brown and yellow. The domestic species of Morchella are all very brown with spikes. A distinction should be made when choosing.

Third, the distribution range of Morchella

Wild Morchella is distributed in Shaanxi, Gansu, Qinghai, Xizang, Xinjiang, Sichuan, Shanxi, Jilin, Jiangsu, Yunnan, Henan, Hebei, Beijing, Hunan, Guizhou and other regions.

Morchella is a kind of wild precious fungus, which is named Morchella because its cover surface is uneven and shaped like sheep tripe. Growing in the natural environment, the monomer can reach more than 200 grams. At present, more than 20 kinds of Morchella have been found in China.
