The role of greenhouses is originally these, understand the advantages and disadvantages of vegetable greenhouses
1. The greenhouse can realize the production of off-season vegetables.
At present, the greenhouse can realize the early listing of spring crop vegetables and fruits, delay the harvest period of autumn crop vegetables, and produce winter vegetables. Greenhouses achieve year-round vegetable supply by staggering vegetable production seasons, and people can eat fresh vegetable products on their tables at any time.
2. Greenhouses produce green and pollution-free vegetables.
Greenhouses can maximize the isolation of pests and diseases by creating their own microenvironmental climate (insect-proof nets are arranged at the vents of greenhouses) and reduce damage to plants caused by outdoor dust and smog. At the same time, the greenhouse can reduce the damage to crops caused by natural disasters and produce high-quality pollution-free vegetables.
3. Greenhouses are efficient and energy-saving.
Effective use of natural sunlight in winter to produce high-quality off-season vegetables. Greenhouses use light-transmitting covering materials to heat up quickly and have good light. The temperature inside the greenhouse is more than 20 degrees higher than the outside world on sunny days, and 2 to 3 degrees higher at night. Since the temperature for most vegetable production is 20 to 30 degrees, and the very low temperature for growth is at least 5 to 8 degrees, winter vegetable production can be completed through greenhouse facilities. The temperature difference between day and day in the greenhouse is large, and the nutritional production period is long. The quality of watermelons, melons and fruit-hanging vegetables produced is greatly improved, and the output is greatly increased.
4. The greenhouse can be mechanized.
At present, the vegetable greenhouses we have built over the years can be combined with the Internet of Things control software system to realize intelligent and automatic control of the shading, ventilation, cooling, heating, irrigation and fertilization systems of the greenhouses. Real-time monitoring and control of greenhouses can be achieved with mobile phones and computers, which can save water, fertilizer, electricity, and energy consumption while reducing labor force.
However, if you choose different materials to build a greenhouse, the service life and cost price will naturally be different.
