I. Core Definition and Functions
Vegetable Greenhouse Shed is an agricultural facility that provides a stable environment for vegetable growth by artificially intervening in environmental conditions (temperature, humidity, light, gas, etc.). Its core functions include:
Break through seasonal restrictions: Realize off-season vegetable production and meet the market demand throughout the year.
Optimize the growing environment: Improve vegetable yield and quality through precise control of environmental parameters.
Resist against natural disasters: Protect crops from disasters such as heavy rain, hail, extreme temperatures, etc.
II. Mainstream types and characteristics
According to the differences in structure, materials and functions, vegetable greenhouse sheds can be divided into the following types:
1. Plastic greenhouse (single arch shed)
Structure: With bamboo, steel pipe or galvanized steel pipe as the skeleton, covering single or multi-layer plastic film.
Features:
Low cost: simple construction, short return on investment cycle.
Good light transmittance: plastic film has high light transmittance, suitable for the growth of leafy vegetables.
Limited thermal insulation: It is necessary to improve the thermal insulation capacity in winter through multi-layer covering or heating equipment.
Applicable scenarios: spring and autumn vegetable planting, seedling raising, temporary production.
