I. General Layout Plan
1, layout principles Overall planning and layout of the park
The site strives to be compact as a whole, save land and investment, and pay attention to the greening of the site and the organization of people and logistics in the site. Near the main entrance are office dormitories, ecological multi-span greenhouses, edible fungus stick processing workshops and sterilized seed production workshops.
2, the project construction content
According to the design scheme and construction scale of the project, the specific construction projects of this project park are shown in the following table.
3, construction engineering
(1) photovoltaic solar greenhouse type A
Type A photovoltaic solar greenhouse has a total span of 13m and a total length of 100m. Among them, the span and length of the solar greenhouse on the south side are 10m and 100m respectively. According to the local meteorological conditions and the functional requirements of the greenhouse, combined with the comprehensive factors such as lighting characteristics, reasonable insulation rate and cost of the solar greenhouse, the lighting angle of the front roof and the height of the back wall of the southern solar greenhouse were determined through theoretical calculation of reasonable lighting design. In order to cooperate with the installation of photovoltaic modules on the north side, the greenhouse adopts the form of no back roof. In order to meet the needs of ventilation and cooling, the front roof of the greenhouse is provided with upper and lower vents; In order to meet the requirements of thermal insulation, an electric roll quilt insulation system is designed above the plastic film on the front roof to prevent ultraviolet rays and rain. The installed capacity of each type A greenhouse is 89.78kW * * 285, and the polysilicon module 3 15W is installed according to the fixed bracket. Every 19 photovoltaic modules are connected in series to form a branch, and each type A greenhouse has 15 branches, which are respectively connected to 1 set 16 and 65438+.
(2) Type B photovoltaic solar greenhouse
Type B photovoltaic solar greenhouse has a total span of 18m and a total length of 100m. The southern solar greenhouse has a span of 9m and a length of 100m. The structural dimensions of southern solar greenhouse are the same as those of photovoltaic solar greenhouse type A southern solar greenhouse. The mushroom greenhouse on the north side has a span of 9m and a length of 100m m. The installed capacity of each type B greenhouse is 14 1.75kW, and * * 450 polysilicon modules 3 15W are installed. Every 18 photovoltaic modules are connected in series to form a branch, and each type B greenhouse has 25 branches, which are respectively connected to 16 and 1.
(3) Ecological planting and sightseeing multi-span greenhouse
Ecological planting and sightseeing multi-span greenhouse 1 building, of which Venlo type multi-span greenhouse has a construction area of 5000m2. The supporting facilities of greenhouse environment include: roof ventilation system, external sunshade system, roof window ventilation system, double-layer internal curtain insulation system, wet curtain-fan cooling system, indoor circulating ventilation system, automatic irrigation system, computer automatic control system and high-pressure control system. Cultivation facilities such as fog culture and pipeline culture are installed in the greenhouse.
(4) Other supporting facilities
Office, dormitory, power distribution room and guard room, boiler room, vegetable sorting workshop, edible fungus stick production workshop and sterilized seed production workshop, public works and auxiliary engineering scheme, water supply and drainage engineering, power supply engineering, heating engineering and site engineering.
Two. Agricultural programme
Analysis on Growth Habits and Economic Value of Crops in Protected Fields
Combined with the positioning of the park and overall consideration of investment income, the park chooses the direct combination of edible fungi production and photovoltaic power generation facilities (laying photovoltaic modules on the roof of edible fungi greenhouse) for photovoltaic facility agricultural production; Pure facility production is mainly based on fruits and vegetables, supplemented by cherries (fruits and vegetables can get quick results). The production process takes safety, green, high quality and high efficiency as the fundamental goal, adopts advanced facility production technology, formulates scientific and practical safety production technical regulations according to different cultivation seasons and cultivation methods, produces fruits and vegetables, realizes the value proliferation of the industry and continuously improves the added value of agricultural products by introducing urban leisure and other links.
