A way to plant high-yield edible bacteria
A large number of edible strains, such as mushrooms, mushrooms, golden needle mushrooms, monkey mushrooms, black molluscs, silver ears, double mushrooms, etc., are currently being cultivated, broadly divided into fungus filament periods and sub-temporal periods or two developmental periods. The conditions required for each mushroom at both stages are similar and different. At that point, their biological properties are designed to achieve high-yield quality if they are able to create the good conditions they need。
1. Nutrients, mainly carbon, nitrogen and mineral elements
Carbon nutrients are a major component of myceloids and sub-entities and a source of energy for their growth and development. Carbon accounts for about 50-65 per cent of mushroom dry matter. Cultures such as cotton seed shells and sawdust are the main sources of carbon。
2. Nitrogen is the main source of protein and nucleic acid. It is also a major component of myceloids and sub-entities and a material basis for delicious edible fungi, especially the abundance of amino acids (up to 18), which cannot be formed without nitrogen。
The normal growth of edible bacteria requires not only sufficient carbon nitrogen nutrients but also a reasonable ratio, commonly known as carbon nitrogen ratios. The proportion of mushrooms of all types is 20:1 at the growth stage of the fungus and 30-40:1 at the development stage of the sub-entity. In production, wheat millet, corn flour, bean bread powder, ammonium nitrate, urea, etc. Sometimes added to adjust the ratio of carbon to ammonia. All mushrooms are the same, and it is difficult to achieve high-yield quality, even if they are not adapted to their original formulations and raw materials, without this and that。
3. The normal growth of the mineral element food bacteria also requires mineral elements and trace elements such as calcium, magnesium, phosphorus, potassium, iron and zinc. These substances, although small in demand, are important, and their content in the main material is generally sufficient. In some cases, magnesium sulphate, herbide (potassium) and chicken dung (phosphorous) are added。
Two. Water and humidity
It is one of the main components of aquatic filaments and sub-entities and, more importantly, the metabolism of life activities, which cannot take place without water. Fresh mushrooms contain as much as 85-90% water. The water in the culture base is the main source of moisture for the consumption of bacteria to grow, but excessive moisture is detrimental. The appropriate water content is 65-75 per cent. Take the material and suck the water, squeeze it with your fingers and pull it out without dripping. In the case of cotton hulls, the water mass ratio is approximately 1:1. 2-1. 5, and excessive additions prevent mycelitis growth。
Humidity refers to the relative humidity of the air, which is not only directly related to the growth and development of the edible bacteria, but also affects the distribution of water in the substance, especially during the development of the sub-entity. If the humidity is insufficient, production will decrease. Less than 60 per cent of the sub-entities do not grow, and less than 45 per cent of the original base ceases to divide or even die. Appropriate air moisture ranges from 85 to 93 per cent (the sub-entity is persistent). In the process of planting, spraying is needed to replenish the moisture and increase the relative humidity of the air. In particular, it is at an advanced stage that it is possible to use water-added or impregnated cultures to increase yields。
Three. Humidity
All kinds of mushrooms require a certain temperature ability for normal growth and development. Different from the growth and development of the fungus and sub-entity, there are even “love” conditions for temperature change. For example, mushrooms can facilitate the formation and development of sub-entities if they are stimulated by a temperature difference of 10 a day. For the cultivation of mushrooms described above, the most suitable temperature for the growth of the fungal line is around 25 (i. E. 30 for black molluscs) and for the development of the sub-entity is generally around 15. Herbs and mushrooms are warm, morbid cords are well developed at 35 and the body is well developed at 30-32。
Temperature is an important factor in the growth and development of edible bacteria. At present, natural time-saving cultivation is more prevalent in production, which is dominated by natural temperature conditions (artificial air conditioning is also mainly the manufacturing of temperature conditions). As technology progresses, the varieties of edible bacteria continue to improve and changing their temperature properties is one of the main tasks. For example, pl
The edible bacteria are less demanding for light, and the silks can grow in dark conditions. The division and growth of a sub-entity requires a certain amount of dispersive light, and direct light is prohibited. It's completely dark, it's poor and it's slow. Light can be coloured, dark. The light is also associated with temperature. Cultivation in the northern sheds requires sunlight and heating, but emphasis is placed on preventing excessive temperatures, excessive light and shade of the sun with straw curtains。
Six. Ph value
In the edible fungal aerosolic environment, the ph value does not exceed 7 (neutral) and ranges between 5. 5 and 6. 5. And the mushrooms are more resistant to alkalis and grow in ph8. Monkey mushrooms are acid-resistant, they grow in ph5. In the process of cultivation, acidic substances such as sugar are added and the culture base becomes acid at high temperature. It also focuses on local water quality, which is its ph value. The formulation should focus on creating a suitable ph environment. Some add acid fertilizers such as lime or ammonium nitrate, while others are enhanced。
Add calcium and nitrogen to adjust the ph value of the culturer。
The addition of a certain amount of plaster can act as a buffer for the prevention of acid or alkyl。
