Product Advantages

1. Extended Harvest Period and High Yield: Long-season cultivation allows for a harvest period of 8-10 months, with a single plant yielding 3-5 kg or more, translating to several times the yield per acre compared to open-field cultivation.

2. Extremely High Marketability: Fruits are well-shaped, glossy, thick-fleshed, and uniform in size, with a premium fruit rate exceeding 90%, meeting the demands of the high-end market.

3. Controllable Environmental Risks: Effectively avoids common open-field physiological and disease problems such as sunburn, blight, and blossom-end rot, ensuring stable production.

4. Year-Round Supply and Benefits: Enables off-season and year-round stable supply, resulting in significant economic benefits.

Product Parameters

Environmental Parameters

Temperature:	Daytime: 25-30°C, Nighttime: 16-18°C (Crucial: Nighttime temperatures consistently below 15°C can negatively impact fruit set and development).
CO₂ Concentration:	Sunny days: 800-1000 ppm (Supplementation can promote fruit enlargement and increase yield).
Air Humidity:	60%-70%. Excessive humidity (>80%) can induce diseases and affect pollination.
Light:	Prefers strong light; daily cumulative light exposure should not be less than 25,000 Lux. Insufficient light can easily lead to flower and fruit drop.

Water and Fertilizer Parameters

Irrigation EC Value:	Seedling/Flowering stage: 2.0-2.5 mS/cm, Peak fruiting stage: 2.8-3.5 mS/cm.
Irrigation pH Value:	5.8-6.2. (slightly acidic).
Key Nutrients:	High potassium and high calcium requirements are prominent. During the fruiting period, sufficient calcium (to prevent blossom-end rot) and potassium (K) supply are necessary to promote color change and weight gain.

Cultivation Management Parameters

Planting Density:	2.0-2.2 plants per square meter (sparse planting facilitates ventilation and light penetration, improving the quality of individual fruits).
Pruning Method:	Double or triple trunk pruning is commonly used (retaining 2-3 strong lateral branches at the first branch point), and timely removal of lower old leaves and internal vigorous shoots.
Pollination Method:	Primarily relies on natural pollination (requiring plant vibration or the use of bumblebees). Fruit-setting agents can also be used to induce pollination, but this can easily affect fruit shape.
Harvesting Standards:	Harvest at the green-ripe stage (deep green and glossy skin) or the bell pepper stage (fully colored), depending on market demand. Fruit firmness must meet the standard.

Covering material

PEP plastic film: chemically stable, heat-resistant, antifreeze, waterproof, moisture-proof, and drip-proof.

Thickness: 0.12mm/0.15mm/0.18mm/0.2mm;

Lifespan: more than 8 years.

Warranty: 3 years.

system

Cooling system Exhaust fan has the galvanized housing, a large aluminum wheel, a 0.8mm frame, and a 0.4mm thick blind. The cooling pad is made of polymer wet curtain paper, which is a special product that has been specially treated to have high structural strength, corrosion resistance, and excellent air permeability and water resistance. The air enters the greenhouse through the cooling pad, which has the effect of cooling, moistening and dust removal.
Heating system Greenhouse heating system refers to a set of suitable heating facilities selected to meet heating needs, including heat source, heat dissipation facilities, and heat transfer facilities. The main accessories include boilers, transmission pipelines, circulating water, radiators, and various control or regulating valves.
Shading system Internal shading is installed inside the greenhouse, fixed to the structure and matched with the frame; its net is made of white aluminum foil and secured by white support wires, achieving 65% shading rate via light reflection. External shading is fixed outside the greenhouse frame and supported by columns and beams; its net is made from HDPE, PE, PB, PVC, recycled/new materials, etc., treated with UV stabilizers and anti-oxidants for high tensile strength, aging/corrosion/radiation resistance and light weight, secured by black support wires, and delivers a better 75% shading rate through light absorption.
Irrigation system Its working principle is to draw irrigation water from the source, pressurize, purify and filter it, then deliver it to field irrigation facilities via pipelines. Drip arrows suit soilless cultivation (3–4 per meter, 1.6m planting spacing), including main pipelines (φ50–φ63), connectors, φ16/1.2mm PE pipes and drip arrow four-piece sets, excluding fertilizer applicators. Drip irrigation applies to ground planting (drip tape spacing 0.8m, φ20/16 PE pipes), with components including water pumps, proportional fertilizer applicators, main pipelines (φ32–φ63), PE pipes and connectors.
Fertilization system Fertilization system: You can choose the corresponding type according to actual needs, manual type, electric type, smart type, and can be connected to mobile phones and computers for remote control. More details will be shown in the proposal.
Control system Designed for agricultural greenhouses, environmental control and weather observation, this automatic system monitors key agricultural factors including wind speed/direction, air/soil temperature and humidity, air pressure, rainfall, solar radiation and UV intensity. Users can choose between ordinary power distribution cabinets and intelligent temperature control systems. The latter uses outdoor weather stations and indoor sensors to detect and record temperature, humidity, light, CO₂ concentration, substrate temperature and humidity, and supports remote control via computer and mobile phone.
