Standard Data for Building High-Quality Products in Vertical Farms for Leafy Vegetables: A Guide to
作者: 时间: 2026-06-05
In the industrialization of smart agriculture and facility agriculture, vertical farms (plant factories) for leafy vegetables have become the absolute mainstay for the efficient cultivation of leafy greens (such as lettuce, bok choy, and ice plant). However, for investors and contractors, how to define whether a vertical farm meets the construction standards for "high-quality products"?
A truly modern plant factory is not simply a matter of "hardware assembly," but requires a series of high-precision, agronomically compliant standard data as support. Below is a summary of the industry-recognized core standard data and technical indicators for building high-quality leafy vegetable vertical farms:
I. Space Utilization and Structural Standard Data
A high-quality leafy vegetable vertical farm must maximize yield within a limited space.
Cultivation Layer Number and Spacing Standards: Based on the biological characteristics of leafy greens (such as lettuce), a high-quality construction plan typically designs 5 to 8 layers of vertical cultivation racks, with the net height of each layer controlled between 35cm and 45cm. This ensures sufficient space for leafy vegetable growth and mechanized operations while increasing the utilization rate of the vertical space by 500% to 800%.
Planting Density Indicators: During the seedling stage, high-quality standards allow for 800-1000 plants/m²; after transplanting, the planting density of mature vegetables should be maintained at 20-25 plants/m² to ensure optimal light and airflow for each plant.
II. DFT/NFT Fluid Dynamics and Water & Fertilizer Standards
Hydroponic fluid dynamics is the lifeline of vertical farms for leafy vegetables.
Circulation System Selection: High-quality standards typically employ a combination of DFT (Deep Hydroponics) and NFT (Nutrient Film Cultivation) systems. The DFT system requires a stable liquid level of 5-8cm and strong resistance to power and water outages.
Water Quality and Dissolved Oxygen (DO) Data: Dissolved oxygen in the nutrient solution is crucial for root development. High-quality construction standards require the installation of a high-efficiency dissolved oxygen device to maintain a stable dissolved oxygen (DO) level of 6-9 mg/L in the root zone nutrient solution.
Precise Water and Fertilizer Control: The fully automated nutrient solution control system must achieve an EC value (electric conductivity) accuracy within ±0.05 mS/cm and a pH value dynamic adjustment accuracy within ±0.1 mS/cm to ensure that leafy vegetables do not suffer from root burn or disease.
III. Light Environment and Microclimate Control Standard Data
LED Photonic Quantum Flux Density (PPFD): For leafy vegetables, the optimal light standard after transplanting is 150 μmol/m²·s - 250 μmol/m²·s. The light formula should use a customized red and blue full spectrum, and the ratio of red to blue light must be precisely adjustable according to the process.
Microclimate Environment Data: Indoor daytime temperature should be maintained at 22℃-24℃, and nighttime temperature at 16℃-18℃ (diurnal temperature range controlled at 6℃-8℃ to facilitate nutrient accumulation); relative humidity should be controlled at 60%-75%; carbon dioxide (CO2) concentration should accumulate to 800ppm-1200ppm during daytime illumination to double the photosynthetic efficiency of leafy vegetables. IV. Yield and Comprehensive Benefit Standard Data
Growth Cycle Shortening Rate: With the synergistic effect of the above-mentioned high-quality standard data, the entire cycle of high-quality lettuce from sowing to harvest can be shortened to 28-35 days, a reduction of over 30% compared to traditional methods.
Food Safety and Resource Indicators: Leaven greens leaving the plant must achieve 100% zero pesticide residue; the closed soilless cultivation system improves water use efficiency by over 90% and fertilizer use efficiency by over 80%.
Construction Service Provider Technical Strength Assessment
