Product Advantages

1. Extended Harvest Period: Through year-round production or long-season cultivation, the harvest period can be extended to 6-8 months, far exceeding that of open-field cultivation.

2. High and Stable Yield: Individual plant yields can reach 10-15 kg or more, with annual yields per unit area several times that of open-field cultivation.

3. Excellent Quality Consistency: Precise water and fertilizer management allows for the production of high-quality marketable melons that are straight, uniformly colored, crisp, and have extremely low pesticide residues.

4. Effective Protection Against Adverse Weather Conditions: Completely overcomes the effects of adverse weather conditions such as low temperatures, rain, and high temperatures, and fundamentally eliminates soil-borne diseases (such as Fusarium wilt).

Product Parameters

Environmental Parameters

Temperature:	Daytime: 25-30°C, Nighttime: 16-18°C. Temperatures should not be too low during the seedling stage and at night.
Air Humidity:	Daytime: 60%-75%, Nighttime: <85%. High humidity is a major factor inducing disease.
CO₂ Concentration:	Sunny days: 800-1000 ppm (Supplementation can significantly increase yield).
Light:	Daily cumulative light intensity not less than 20,000 Lux; high light saturation point; prefers strong light.

Water and Fertilizer Parameters

Irrigation EC Value:	Seedling stage: 1.8-2.2 mS/cm; Peak fruiting stage: 2.2-2.8 mS/cm.
Irrigation pH Value:	5.5-6.2 (slightly acidic).
Key Nutrients:	High potassium and high calcium requirements. During the fruiting period, the nitrogen (N):potassium (K₂O) ratio should be approximately 1:1.5, and attention should be paid to calcium fertilizer supplementation to prevent blossom-end rot.

Cultivation Management Parameters

Planting Density:	2.0-2.5 plants per square meter (common wide and narrow row planting).
Pruning Method:	Single vine pruning, continuous vine training and lowering, timely removal of lateral branches and old leaves at the base.
Pollination Method:	Most modern greenhouse varieties are parthenocarpic and can set fruit without pollination.
Harvesting Standard:	Based on market demand, fruits are usually harvested when the fruit length reaches 30-35cm and the flowers have not completely fallen off.

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.
