Covering Materials

MEIRYO(BerryCool®): Agricultural Covering Material

As the material efficiently reflects the infrared rays of sunlight, the heat source, it allows as much visible light as possible to pass through, which is necessary for photosynthesis, while suppressing temperature rise inside the greenhouse.

Characteristics

UV resistance and excellent durability.
No elongation or shrinkage. Stable shape even during processing.

Applications

Covering materials on greenhouses.
Interior screens in greenhouses.

Materials	Shading Rate (%)	Width (mm)	Length (m)
WARIFU MEIRYO 20	20	1000 or 2100	100
WARIFU MEIRYO 30W	30
WARIFU MEIRYO 40	40
WARIFU MEIRYO 50	50

It is a highly versatile net-like polyethylene nonwoven fabric. They are available in four types: White, Black, Silver, and Root-Control. Each type has different specialized characteristics, so you can choose the one that best suits your crops and the season.

Characteristics

Moderate hydrophobicity for rain protection.
Mesh-shaped fabric to prevent entry of pests.
Windproof function for heat retention.

Applications

Row Coverings for open-field culture.
Covering materials on greenhouses.
Sheets for Lawn protection.

ROUND COOL: Heat Shielding Covering Material for Tunnel Cultivation

It is a heat shielding covering material for tunnel cultivation using MEIRYO(BerryCool®). While reflecting the infrared rays of sunlight, the heat source, it allows as much visible light as possible to pass through to maintain brightness, thus preventing the inhibition of photosynthesis in crops.

Characteristics

Efficient reflection of infrared rays to suppress temperature rise of leaf and soil.
Mesh-shaped fabric to prevent pest infestation.

NUKUNUKU: Heat-Retention Material

The covering material is reinforced by sandwiching a special heat-retaining nonwoven fabric with WARIFU®, promising dehumidifying and heat-retaining effects. Using WARIFU®, it is highly durable and does not shrink easily even when it absorbs moisture.

Characteristics

Three-layered structure with heat-retaining nonwoven fabric sandwiched with WARIFU®.
High heat retention due to its infrared-absorbing ability.
Fine fibers of the nonwoven fabric to prevent pest infestation.

Applications

Covering materials for tunnel cultivation.
Interior screens in greenhouses.

TERUTERU: Reflective Material

It is an irregular reflection sheet made by thermo-compression bonding of WARIFU® and synthetic paper made of ultra-fine fibers. The special fiber structure achieves high reflection performance and infrared shielding effect. Since it reflects sunlight irregularly, it also has the effect of preventing uneven color and leaf burn.

Characteristics

Improvement of growth and coloration by its high reflection.
Prevention of uneven color and leaf burn by its irregular reflection.
Suppression of soil temperature rise by blocking infrared rays.

Applications

Row Coverings.
Mulching materials for vegetables and deciduous fruit trees.
Prevention of pests infestation.

Photosynthetic Efficiency Improving Device

CONDUCTOR: Photosynthetic Efficiency Improving Device

Measuring illuminance, CO₂, humidity, temperature, and wind in the greenhouse, the system controls efficiency of CO₂ air and photosynthesis using light. Data management is also available as it is equipped with the technology of CO₂ controller BREATH.

Characteristics

Reduction of operating costs by controlling the device in each area individually.
Customizable device according to requests including light color and angle.
Grasp of the whole environment in greenhouses by receiving information from many sensors wirelessly.

OCES-200S: CO2 Controller

The sensor box installed in the greenhouse constantly monitors CO₂ and controls efficient spraying. The device applies an appropriate amount of CO₂ in each area effectively, promising stable and active photosynthesis without being affected by the opening and closing of skylights and ventilation.

Characteristics

Effective spraying of CO₂ to improve the growth of vegetables and fruit trees.
Huge reduction of operating costs by utilizing it locally, instead of the whole greenhouse.
Clean indoor environment with no temperature rise by using liquid CO₂ cylinders.

Applications

Open field cultivation, greenhouse cultivation, CO₂ spraying in plant factories.

SMART AGRI

We conduct an elevated strawberry cultivation experiment using our SMART AGRI SYSTEM with our partner farmers. Our hybrid panels simultaneously generate power and supply hot water in our solar power facility. The generated electric energy is stored to supply electricity to lighting and air conditioning. Furthermore, the antifreeze heated by thermal energy is stored in a hot water tank to warm the culture base. Our facility includes many features: MEIRYO(BerryCool®), NUKUNUKU, and hoses crawling along the seedlings to bring in CO₂ directly for active photosynthesis.
