Description

TECHNICAL FIELD

[0001] The utility model belongs to edible fungus cultivation technical field, concretely relates to a kind of intelligent three-dimensional cultivation system of edible fungus using idle tobacco leaf curing barn reformation. BACKGROUND

[0002] Tobacco leaf curing barn is special facility for curing tobacco leaf in tobacco planting process, after tobacco harvesting season, curing barn is often idle, utilization rate is low, leading to a large amount of land and space resources are occupied, unnecessary waste is formed.

[0003] In addition, the adjustment of tobacco planting policy and the change of flue-cured tobacco industry in some areas make some curing barns face the risk of being abandoned. How to effectively use these idle curing barns has become a problem to be solved.

[0004] Artificially cultivated edible fungi are rich in nutrients, delicious and tender in taste, contain a variety of amino acids, vitamins and mineral components, and are popular in domestic and foreign markets. With the improvement of people's living standards and the increasing demand for healthy food, the market demand for artificially cultivated edible fungi is increasing year by year, and the development of artificially cultivated edible fungi has good economic benefits and broad market prospects. However, traditional artificial cultivation of edible fungi mostly adopts flat cultivation method, which occupies a large space and has low land utilization rate.

[0005] In recent years, with the continuous development of information technology, automation technology and agricultural cultivation technology, intelligent three-dimensional cultivation technology is increasingly widely used in the field of agriculture, and the cultivation of many crops and edible fungi has begun to develop towards intelligence and three-dimensionality to improve production efficiency and product quality. Transforming idle tobacco leaf curing barn into intelligent three-dimensional cultivation system for artificially cultivating edible fungi is an innovative attempt in agricultural technology development. This transformation not only solves the problem of idle curing barn, but also significantly improves space utilization efficiency and resource management through intelligent technology, thereby promoting the development of edible fungus industry. This approach conforms to the development trend of modern agricultural technology and has significant practical significance and promotion potential.

[0006] Although intelligent three-dimensional cultivation system can effectively expand cultivation area and improve unit yield in limited space, it still faces many challenges in implementation process, such as environmental control, facility equipment configuration, cultivation technology optimization, cost control and personnel quality improvement.

[0007] Artificial planting of edible fungi has strict requirements on environmental conditions, and different growth stages of edible fungi have different requirements on temperature, moisture, carbon dioxide and pH value. For example, temperature is an important factor affecting the growth and development of edible fungi, and different edible fungi require different temperature ranges for growth. Each type of edible fungi can only grow within its suitable temperature range. Moisture is an important component of edible fungi cells, and about 90% of the mycelium and fresh mushroom body is water. The moisture required for the growth and development of edible fungi is mostly obtained from the culture medium. The moisture content of the culture medium is an important factor affecting the growth of mycelium and the formation of fruiting bodies. Only when the moisture content is appropriate, fruiting bodies can be formed. The relative humidity required for the growth of mycelium of most edible fungi is 65% to 75%, and the relative humidity required for the development of fruiting bodies is 80% to 95%. Ventilation is an important cultivation measure in the growth process of edible fungi, which can meet the oxygen needs of edible fungi and discharge metabolic waste carbon dioxide. In the three-dimensional cultivation environment, due to the existence of multi-layer structure, the air circulation, heat distribution and humidity transmission are relatively complex, and it is difficult to ensure that the environmental conditions of each layer of cultivation shelf can accurately meet the growth needs of artificial planting of edible fungi. In summer, the bottom cultivation shelf is relatively cool, while the top cultivation shelf may have a sharp rise in temperature due to proximity to the roof or direct sunlight. In winter, the bottom cultivation shelf may have high humidity due to poor ventilation, further increasing the difficulty of accurate control of environmental parameters. In addition, the intelligent three-dimensional cultivation system for edible fungi needs to customize special three-dimensional cultivation shelves, irrigation systems, ventilation systems, lighting systems and intelligent control systems and other facilities and equipment. These devices need to be reasonably designed and installed according to the space structure of the curing house and the cultivation requirements of artificial planting of edible fungi. On the one hand, the structure of the cultivation shelf should be stable enough to withstand the weight of multi-layer cultivation, and it should also be easy to operate and manage. On the other hand, the irrigation system should ensure that the edible fungi on each layer of cultivation shelf can uniformly obtain water, and the ventilation and lighting systems should also be uniformly distributed in the three-dimensional space. These have high requirements for the design and installation of facilities and equipment. SUMMARY
