Description
Technical field
The present invention relates to agricultural planting facility and implantation methods, be specifically related to the wet long-term cropping facility of a kind of protecting field control and implantation methods.
Background technology
Current protecting field (hot house) plants anti-season crop on a large scale, provides market ensure for s, melon and fruit demand, and so-called protecting field is exactly membrane sealed, adds sunlight irradiation, obtains temperature at low temperature season and ensures plant growth.Owing to protecting field lacks functional design, air-flow exchange cannot ideal carry out.Long-term practice is it has been observed that the crop that crop in protecting field grows with natural season is compared: branch body is thin and weak, and blade is thin, and fruit is sparse, yield and low quality.
In the closed condition, protecting field is irradiated by sunlight has two physical factors to rise, and one is temperature, and two is humidity.In whole process, humidity ratio temperature rises soon.When temperature reaches 35 DEG C, humidity can reach 100%.In this condition, inside and outside blade, osmotic pressure is suitable, and blade face moisture evaporation stops.The root system of crop is thus stopping absorbing water from soil；Multiple nutrient matter also cannot enter plant therewith.The supply of crop endotrophic is interrupted, have impact on the normal physiological function of crop largely, here it is vegetables in improper season melon and fruit and normal vegetable melon and fruit have the reason place of very big-difference at quality and yield.
Under the winter extreme weather conditions such as ice and snow, in the wet protecting field of non-control, form low temperature and high relative humidity.If not taking intensification wet down measure, create condition to fungus breedings such as downy mildews, booth vegetable, melon and fruit are had the threat causing total crop failure.
Summary of the invention
The present invention solves the defect of tradition long-term cropping; the wet long-term cropping facility of a kind of protecting field crop temperature control and implantation methods are provided, according to booth volume, calculate and change air quantity; select the high-performance air stove of certain thermal capacity according to air quantity, in canopy, carry the natural wind after heating.Due to hot-blast outlet temperature-controllable, can according to the plant growth requirement to humiture, utilize temperature, wet meter, it is tracked the change of humiture in air-supply process in canopy measuring, formulate relevant parameter, input Control System of Airheater respectively, control air output, create suitable humiture environment for plant growth.
The present invention is to solve the problems referred to above, design creates the ventilating system of a set of controllable temperature humidity, thoroughly solves humiture environment severe in protecting field, and suitable condition has been built in the production in enormous quantities for anti-season high-quality vegetable melon and fruit.
The opposite side of canopy body is provided with canopy face, in canopy body, portion is provided with thermometer and the list-directed hot blast stove system of humidity, 2 wind box it are provided with in body of wall, packaged air conditioner is positioned at upside, hot bellows is positioned at downside, the canopy face end being positioned at body of wall offside is provided with the air draft ditch of concave downward, and extraneous wind enters from hot bellows and packaged air conditioner, enters underground from air draft ditch and flows out from two ends；The exhaust outlet of air stove connects purifier.When being in hot and humid in canopy, lowered the temperature dehumidifying by cold wind mouth air intake；When being in low temperature and high relative humidity in canopy, heated up dehumidifying by hot-air mouth air intake.
Cleaning system includes the outlet of exhaust system and connects the depurator being vertically arranged, depurator is that inside is provided with the columnar structured of some helical pipes, the outlet of helical pipe connects collecting-tank, and described helical pipe is respectively equipped with some shower nozzles, and shower nozzle is connected with the water pump within collecting-tank.
The implantation methods that the wet long-term cropping facility of protecting field crop temperature control carries out is utilized to comprise the following steps:
(1) temperature inside and outside canopy and humidity are monitored, it is judged that in canopy, be in hot and humid or low temperature and high relative humidity；
(2) according to booth volume, calculate and change air quantity；
(3) air quantity is inputted Control System of Airheater, in canopy, carry the natural wind after heating；
(4) formulate relevant parameter, input Control System of Airheater respectively, control air output in real time；
(5) it is tracked the change of humiture in air-supply process in canopy measuring；
(6) reach when predetermined temperature and humidity out-of-blast.
The effect of the present invention is in that: create plant growth to humiture requirement, and crop is in evaporating state, well developed root system all the time, and branch body is sturdy, and blade is plump, and fruit fills, output increased.
