Advantages of plastic multi-span greenhouses:
1. Increase the temperature and humidity in the shed. Generally, the temperature of plastic greenhouses can be increased by 2~5°C compared with the outdoor temperature, and the highest increase is 6~8°C; the humidity can be increased by 7%~13%. Therefore, plastic greenhouse seedlings are conducive to seed germination, cutting rooting, and can prolong the growth period of seedlings. Under the condition of no heating, the growth time can be extended by 1 month.
2. It is easy to control the environmental conditions. Seedlings can be protected from wind, frost, drought, air pollution and other hazards, which is beneficial to control conditions such as temperature, humidity and ventilation. Fertilization and irrigation can be installed with fixed equipment, which can not only reduce labor intensity, but also facilitate rich management.
3. The seedlings grow rapidly and neatly. Generally, the height growth of seedlings is 1 to 2 times larger than that of open field seedlings of the same age, and the coarse growth is about 1 times larger, and the growth is uniform.
4. Simple construction and low cost. Compared with greenhouses, plastic greenhouses are simpler and easier to build, more convenient to dismantle and turn, and lower in cost, which is conducive to mechanized production and industrialized seedling cultivation.

Application of multi-span glass greenhouse
Due to the large-span spire design, the indoor operating space is large, the greenhouse utilization rate is high, and the display effect is good. Glass greenhouses are generally used in large-scale sightseeing greenhouses, seedling greenhouses, flower markets, large shopping malls or ecological restaurants.
The main beam of multi-span glass greenhouse adopts truss beam, which has strong bearing capacity. The roof is triangular ridge type, which can make the indoor light evenly distributed. The main steel structure is made of hot-dip galvanized pipe, surrounded by insulating glass, and the top is covered with 5mm thick tempered glass. The greenhouse is equipped with internal and external sunshade cooling system, fan wet curtain strong cooling system, anti-condensation system, skylight ventilation system, heating system, intelligent control system, mobile seedbed system, mobile sprinkler system, power distribution system, etc.
