Description
Technical field
The present invention relates to agricultural automation control field, particularly relate to a kind of intelligent greenhouse system of carbonic acid gas Automatic adjusument.
Background technology
Greenhouse (greenhouse), also known as greenhouse, can printing opacity, insulation (or heating), be used for the facility of cultivated plant.In the season being not suitable for plant growth, breeding time and increase yield can be provided, be used for plant cultivation or the nursery etc. such as low temperature season warm season vegetable, flowers, forest.
The kind in greenhouse is many, can be divided into again many types according to different roof truss materials, lighting material, profile and condition etc. of heating, as glass greenhouse, plastics polycarbonate greenhouse; Single-ridgepole glasshouse, attached-greenhouse; Single roof greenhouse, two roof greenhouse; To heat greenhouse, unheating hothouse etc.Greenhouse structure answers sealing thermal insulation, but should be convenient to aeration-cooling.There is in modern greenhouse the equipment controlling the condition such as temp. and humidity, illumination, automatically control to create the optimal environmental condition needed for plant with computer.
Greenhouse generally needs to consider the following aspects:
1. light transmission
Greenhouse is daylighting building, and thus light transmittance evaluates one of greenhouse light transmission most basic index.Light transmittance refers to the percentage into the quantity of illumination in greenhouse and the outdoor quantity of illumination.Greenhouse light transmittance is by the impact of greenhouse glazing material light transmission and Keelof green house shadow factor, and along with the difference of Various Seasonal solar radiation angle, the light transmittance in greenhouse is also changing at any time.The height of greenhouse light transmittance just becomes plant growth and selects the direct acting factor of long-term cropping kind.Generally, muiti-span greenhouse is 50% ~ 60%, and the light transmittance of glass greenhouse is 60% ~ 70%, and greenhouse by solar heat can reach more than 70%.
2. heat insulating ability
Power consumption of heating is the major obstacle of greenhouse winter operation.Improving the heat-insulating property in greenhouse, reduce energy consumption, is the most direct approach improving hothouse production benefit.The insulation in greenhouse is than being the basic index weighing greenhouse heat-insulating performance.Greenhouse heat-insulating is than referring to greenhouse building enclosure area coverage that greenhouse light transmissive material area coverage that thermal resistance is less and thermal resistance the are larger ratio with ground area sum.Insulation, than larger, illustrates that the heat-insulating property in greenhouse is better.
3. durability
Greenhouse construction must consider its durability.Greenhouse durability is subject to the impact of the factors such as the bearing capacity of greenhouse material ageing-resistant performance, greenhouse main body structure.The durability of light transmissive material, except the intensity of self, also show that material transmissivity is constantly decayed along with the prolongation of time, and the attenuation degree of light transmittance is the deciding factor affecting light transmissive material service life.General steel construction greenhouse service life is more than 15 years.Require design wind, snow load 25 years one chance peak loads; 5 ~ 10 years service life of bamboo-wood structure simple greenhouse, design wind, snow load 15 years one chance peak loads.
Under Greenhouse operation is in high temperature, high humidity environment for a long time, the surface anticorrosion of component just becomes one of key factor affecting greenhouse service life.Steel construction greenhouse, stressed agent structure generally adopts light-gauge steel section, and self resistance to corrosion is poor, and adopt in greenhouse and must use the process of galvanizing by dipping surface anticorrosion, thickness of coating reaches more than 150 ~ 200 microns, can ensure the service life of 15 years.For timber structure or reinforcement welding truss structure greenhouse, must ensure to do one-time surface preservative treatment every year.
Carbon dioxide content in air generally accounts for 0.033% (i.e. 0.65mg/L, 0 DEG C, 101kPa) of volume, is lower concerning the photosynthesis of plant.If gas concentration lwevel is lower, photosynthetic rate sharply slows down.Photosynthesis slows down, and is unfavorable for growing of plant.So in the process cultivated plants in plant factor, we suitably can increase the concentration of carbonic acid gas to promote the photosynthesis of crop.But gas concentration lwevel is not more high better.The too high meeting of gas concentration lwevel brings following impact:
First, large quantity research shows, atmospheric CO_2 increases, photosynthesis of plant speed can be made in a short time to increase, but after longer a period of time, photosynthesis rate will decline gradually, and this may be the result of CO2 Photosynthetic Acclimation, cause " source-Ku " balance of the decline of Rubisco vigor and photosynthate in plant corpus to be damaged.
The second, in environment, the rising of CO2 concentration can cause the closedown of plant stomata, thus stomatal conductance is reduced.
3rd, under high concentration CO 2 condition, along with photosynthetic rate improves, the starch in plant leaf blade, polysaccharide increase (Finn, 1982).And the nucleic acid of most plants seed, protein, amino acid equal size have decline in various degree.
In sum, the too high too low growth to plant of gas concentration lwevel is all disadvantageous.Find through investigation, under the condition that temperature, light, water, fertilizer etc. are comparatively suitable, concerning the vegetable crop such as romaine lettuce, water spinach, in seedling stage and setting date, gas concentration lwevel is maintained 0.05%--0.06% and just can carry out high efficiency photosynthesis.In the vegetable ripeness phase, it is the most suitable that gas concentration lwevel reaches 0.08%-0.15%, and the raising of yield of vegetables is also obvious.
Because environment is airtight in greenhouse, easily there is carbonic acid gas skewness on the one hand, be easy to the phenomenon occurring that carbon dioxide content is too low on the other hand.Existing Greenhouse System does not generally do special optimization for carbonic acid gas, only by the way of regularly ventilating, does not consider the demand of each Plants to carbonic acid gas, unfavorable to the growth of plant.
