Description

Two canopy compound heat preservation energy saving sunlight greenhouses
Technical field
The utility model relates to a kind of greenhouse by solar heat.
Background technology
China's hothouse production is elementary paper window greenhouse within a considerable time.After founding of New, change paper window greenhouse into glass greenhouse, i.e. Beijing formula greenhouse.Within 1966, had plastic tunnel, 20 century 70 greenhouse vegetable plantations develop in the whole nation rapidly.From early 1980s, the ground such as Beijing, Tianjin all starts the large-scale attached-greenhouse of introducing or self-built some modernizations are controlled automatically, plan takes external production technology mode to solve north of china in winter vegetable supply problem, but mainly due to three high low with high investment, high energy consumptions, the reason that expensive, comparative effectiveness is low, the overwhelming majority is in succession out of service.China vegetables produce and adopt traditional greenhouse of heating in the north, and because coal fire expense is too high, production benefit is relatively low, and this cannot large area develop in energy starved China, and now, energy-saving heliogreenhouse has just arisen at the historic moment.1985, Liaoning Province adopted heliogreenhouse in Haicheng Earthquake Area, and the production cucumber of not heating winter is obtained successfully, and develops into second generation energy-saving heliogreenhouse by first generation energy-saving heliogreenhouse.The 1987-1989 Ministry of Agriculture organizes northern area to carry out adaptive development research, succeeds, and obtain high yield the happiness temperature fruit vegetables such as greenhouse by solar heat plantation tomato, eggplant, capsicum and multiple leaf vegetables, and area develops into 1000hm2.Nineteen ninety, the Ministry of Finance, State Scientific and Technological Commission, Ministry of Agriculture's project verification develop and spread, set up " the energy-efficient vegetable growing technological development of greenhouse by solar heat coorporative network ", and technique is applied rapidly.
Whole nation facilities horticulture area has reached more than 346 ten thousand hectares, become the country of world's facilities horticulture area maximum, as by the per capita area in town and country, now reach per capita 10.7m2, than the eighties in 20th century, everyone 0.36m2 has increased by 29.7 times, if calculate with current output 20kg/m2, per capita vegetables 143.4kg, as add outdoor vegetable, year is occupied more than 300 kilogram of vegetables per capita, than only 73kg of occupancy volume per person's eighties in 20th century, has increased by 4.1 times, can have 0.82kg vegetables everyone every day like this, meet compatriots completely and eat dish.Therefore, facility area is larger, and vegetables produce needs total amount in a basic balance, and seasonal, zonal relative surplus have appearred in large dish, price drop, decline in benefits.So want stabilize cultivation area, improve quality, increase scientific and technological content, optimize production distribution and crops for rotation species layout, just can increase the yield per unit area and benefit.
From facility level, more than 80% greenhouse and booth are simple structure types, and take bamboo wood, cement pole as skeleton, thick cob wall has reduced land utilization rate, only accounts for 40%~50% availability; Working space is little, and column is many, is not easy to mechanically actuated, can only lean on handwork, let alone automatic management; Insulation, lighting performance is poor, and weak strength, is difficult to resist sleet and impacts, and maintenance is washed away every year every year, for example southern ice and snow disaster in 2008, and facilities horticulture loss is huge.For peasant household, single household can also study for a second time courses one has flunked at any time, only increases maintenance cost.For enterprise, extensive specialized production, maintenance is very inharmonic every year.So do industrialized agriculture industrialization, just must improve facility level and managerial skills.Specifically, transformation plain edition greenhouse, progressively promotes greenhouse level.The wooden cement of improving the soil is steelframe skeleton, and changing straw screen or mat is that thermal insulation quilt covers, and changes manual operations for miniature farm machinery operation, changes the equipment that simple Keelof green house is internal equipment adjusting ambient function, progressively to modernization, automation direction development.To strengthen standardization and the high-quality of Greenhouse Construction simultaneously.
Industrialized agriculture is also referred to as controlled agricultural, and manual control environment is because usually meeting vegetables the best growing condition, thereby obtains maximum economic benefit.The factors such as air, root system temperature, illumination, water, relative moisture, carbonic acid gas and plant nutrition, can carry out Artificial Control.From China's industrialized agriculture, although there is the facility of the A wide selection of colours and designs such as greenhouse, booth, middle hut, sunshade, cold bed, the equipment of internal control environment is less.Such as, regulate indoor temperature height still to carry out gravity-flow ventilation heat radiation by manually opeing the window, pull open film; Irrigate still according to the such broad irrigation of open country, rather than spray drip irrigation; Fertilising is still blindly and chases after chemical fertilizer, rather than quantitative timing is used.Therefore, can say the facility level of China or relatively backward, the energy that expends, material, be manually larger, must progressively improve, and could improve facility level.
Utility model content
The utility model is that traditional greenhouse by solar heat heat-insulating property is low in order to solve when the low temperature season, heat-preserving equipment few problem service life, and then two canopy compound heat preservation energy saving sunlight greenhouses are provided.
