Lida greenhouse is a kind of place that can change the environment of plant growth, create the best conditions for plant growth, and avoid the influence of the four seasons and bad climate. It uses daylighting covering materials as all or part of structural materials, and can be cultivated in winter or other seasons that are not suitable for the growth of open plants. Greenhouse production aims to regulate production period, promote growth and development, prevent and control diseases and insect pests, and improve quality and yield.

The design concept of Lida greenhouse is "adhere to the principle of science and practicality; adhere to the principle of improving the utilization rate of land resources, energy saving, water saving and high efficiency; adhere to the principle of advanced, reliable and appropriate selection of greenhouse structural materials and equipment; adhere to the principle of world leading".

Lida greenhouse mainly includes greenhouse foundation, main structure, covering materials, ventilation system, internal sunshade system, fan wet curtain cooling system, power distribution and electric control system, etc. The greenhouse designed by our company adopts hot galvanized light steel structure, which has strong anti snow ability and long service life, and is committed to building excellent greenhouse projects for customers.

Greenhouse is suitable for planting flowers, vegetables, melons, fruit trees, etc. there are many kinds. According to different materials, it can be divided into the following four kinds: Film greenhouse, glass greenhouse, solar panel greenhouse, solar photovoltaic greenhouse

Greenhouse characteristics

◆ Solved the contradiction between heat preservation and light transmission in greenhouse.

◆ Good heat preservation in winter.

The unique glass sealing structure completely solves the problem of water leakage.

◆ Glass greenhouse has the advantages of beautiful appearance, good light transmittance, good display effect and long service life.

◆ It has the function of preventing drips and fogs. A condensation water collection tank is set under the open gutter, which can lead the condensation water to the end of the greenhouse for discharge after collection, so as to reduce the occurrence of diseases and insect pests.

◆ This type of greenhouse can realize full-automatic control, and the supporting equipment can choose heating system (hot air heating or water heating), sunshade system, micro fog or water curtain cooling system, CO2 supplement system, light supplement system and spray, drip irrigation and fertilization system, computer integrated control system, top spray system, etc.

technical parameter

Design load: wind load 0.30kn/m2,

Snow load: 0.40kn/m2

Span: 6.4m/8.0m/9.6m/10.8m/12m/12.8m/16.0m

Eave height: 3.0m-8.0m

Column spacing: 4.0m/8.0m

Greenhouse characteristics

◆ One span and many spires, the greenhouse has the characteristics of small roof, multiple gutters, large span, etc., and the interior can be flexibly set with partition.

◆ Good lighting performance, even indoor light

◆ It has a strong drainage capacity and can be connected with a large area

◆ Aluminum alloy profiles or special link seals are linked and sealed, with beautiful appearance

◆ It has the function of preventing drips and fogs. A condensation water collection tank is set under the open gutter, which can collect the condensation water and guide it to the end of the greenhouse for discharge, so as to reduce the occurrence of diseases and insect pests

◆ The effect of heat preservation and energy saving is better than that of single-layer glass, which can save a lot of fuel in winter, but the light transmittance is poor compared with that of single-layer glass

◆ Spacious and bright interior, large operation space, high utilization rate of greenhouse

◆ A skylight is set on the top of the greenhouse, which conforms to the flow direction of hot air, is conducive to air flow and heat loss, and is conducive to cooling and dehumidification in summer

◆ Gutter with large flow

◆ Large span, large column spacing and tall type can be widely used as ecological restaurant, leisure and Sightseeing Greenhouse and large flower market

◆ Double layer hollow board and double-layer gutter can be used for top covering to effectively prevent dew formation and reduce energy consumption of temperature rise in winter

◆ solar photovoltaic greenhouse is a new type of greenhouse. It is a greenhouse where solar photovoltaic power generation devices are laid on part or all of the sunny surfaces of the greenhouse. It not only has the power generation capacity, but also provides suitable growth environment for some crops or edible fungi

◆ photovoltaic greenhouse project is the product of the organic combination of sightseeing agriculture and facility gardening. It is an innovative agricultural industry integrating photovoltaic power generation, agricultural sightseeing, agricultural crops, agricultural technology, garden landscape and cultural development

At the same time, Lida greenhouse, according to the needs of customers, can provide the corresponding external shading system, internal shading system, cooling system, heating system and supporting components.

◆ The main function of the system is to shade and cool down in summer, so that the sunlight diffuses into the greenhouse, to ensure that the crops are not burned by strong light. As a result, a large amount of light is blocked, the heat accumulation inside the greenhouse is effectively reduced.

◆ UV and hail resistant, reducing the damage to the top of the greenhouse.

◆ According to the different planting crops, select the screens with different shading rates to meet the needs of different crops for sunlight.

◆ Sunshade cooling: in summer, part of sunlight can be effectively reflected by closing the curtain, which can reduce the greenhouse temperature by 4 ℃ - 6 ℃.

5.2) internal sunshade system 

◆ Anti fog and anti drip: when the internal sunshade system is closed, two independent spaces are formed in the greenhouse, which can effectively prevent the formation of fog and dew in the greenhouse

◆ Energy saving and heat preservation: in winter and night, it can effectively prevent the internal heat of greenhouse from overflowing through radiation or heat exchange, thus reducing energy consumption and greenhouse operation cost

◆ Water conservation: it can reduce evaporation of indoor crops and soil water, effectively maintain air humidity and reduce irrigation water

◆ Composite insulation wall, internal wall insulation and external wall heating, easy to form a good microclimate in the shed

◆ Use thermal insulation quilt, straw curtain thermal insulation and electric rolling machine for rolling in winter

◆ The cooling system is based on the principle of transforming the moist heat in the air into latent heat when water evaporates. The wet curtain is installed on the gable or side wall at one end of the closed greenhouse, and the fan is installed on the gable or side wall at the other end. When the fan exhausts, the negative pressure is generated in the room, forcing the outdoor unsaturated air to flow through the porous wet surface of the wet curtain, a large amount of wet heat in the air is converted into latent heat, so as to realize the cooling of air.

◆ The hot water circulation heating system is adopted in the greenhouse. The hot water heating uses 60 ℃ - 85 ℃ hot water circulation to exchange heat with air. The main equipment is the heat source (geothermal well or boiler) and radiator in the greenhouse.

◆ The greenhouse mainly uses low-temperature hot water for heating, and the temperature of heat carrier water is not high, which is easy to operate and suitable for greenhouse heating.

◆ According to the needs, you can choose boiler heater heating, air conditioning heating and other ways.
