Air conveys clammy air to greenhouse, the method for reducing by 1 summer of greenhouse diurnal temperature, and keeping greenhouse 1 is suitable for solanaceous vegetables
The temperature of growth improves the yield of solanaceous vegetables, improves the output value.
By taking solanaceous vegetables as an example, the application method of greenhouse cooling system of the present invention are as follows:
The optimum growth temperature of solanaceous vegetables are as follows: seedling stage controls at 25~28 DEG C of daytime temperature, 15~18 DEG C of night temperature.Nutrition is raw
The growth temperature for being suitable for during length is 20~25 DEG C, and the phase of yielding positive results is not easy more than 30 DEG C, and 5~10 DEG C lower than daytime temperature of night temperature more have
It can cause fruit drop if nocturnal temperature is higher than 22 DEG C or lower than 15 DEG C conducive to growth.
When rainfall, the canopy film and aproll 3 of greenhouse 1 introduce in bus dump 4 after intercepting rainfall runoff, using sedimentation basin 5
Precipitating and filter screen filtration will after rainwater purification be sent into reservoir 2 in store.In scorching temperature season summer
And the period, it opens the mouth that leaks informaton at left and right sides of greenhouse 1 and is also not enough to reduce by 1 temperature of greenhouse to the temperature for being suitable for solanaceous vegetables growth
Degree can close greenhouse 1 at this time and leak informaton mouth, open air blower 12, exhaust fan 13, while opening micro-spray system, extract reservoir 1 out
Interior clammy air, is distributed in greenhouse everywhere by wind distributing hole 15, is cooled down to greenhouse.It is lower than solanaceous vegetables to temperature of shed
When vegetables suitable growth temperature, system above is closed, stops cooling.When temperature is excessively high, system above can also be opened at night in the evening, closed
Greenhouse 1 leaks informaton mouth, reduces night temperature for greenhouse.Guarantee the suitable diurnal temperature in greenhouse, meets the need of solanaceous vegetables growth
It wants.
When crop needs to water in greenhouse, the rainwater stored in reservoir 2 can be extracted out by water pump, pass through trickle irrigation or spray
Filling device 16 pours crop in canopy.
When needing to divulge information in greenhouse, the mouth that leaks informaton of greenhouse two sides is opened, makes greenhouse and extraneous progress air circulation.
Double skeletons can be selected in the structure of greenhouse and double canopy films are increased with increasing the leakproofness of greenhouse in clammy air circulation
The cooling effect for increasing canopy, keeps greenhouse cooling effect more abundant, is more advantageous to the suitable diurnal temperature guaranteed in greenhouse, mentions
The yield of solanaceous vegetables in high greenhouse.
In order to reduce summer canopy room temperature, the structure of greenhouse can be changed to more connect a vinyl house, double arch vinyl houses, change
Various types of greenhouses such as good figure vinyl house.
Reservoir 2 can also build the outdoor ground close to canopy room in hereinafter, collecting other canopy rooms by rain water collecting system
Rainwater guarantees sufficient water source.
Cooling system of the present invention and wet curtain-fan cooling system are compared in the greenhouse of same size, in greenhouse
Temperature is uniformly set as 35 DEG C, while opening cooling system of the present invention and wet curtain-fan cooling system, and canopy temperature is down to
28 DEG C, the time used in the two is respectively 1h and 0.5h, and the present invention reduces 60% compared with wet curtain-fan cooling system energy consumption, equipment
Cost reduces 55%.
