Description
Technical field
The present invention relates to greenhouse gardening technology fields, and in particular to a kind of intelligent method for adjusting greenhouse humidity.
Background technique
For greenhouse since quantity of pouring water is more, soil moisture is big, and the transpiration rate of the evaporation of ground moisture and vegetable crop is also big.In sky
Between smaller, steady air current, plastic covering film under confined conditions, is not easy to carry out gas exchanges with extraneous, makes the sky in greenhouse
Gas phase is relatively high to humidity, and especially in the case where night covers straw screen or mat cotton-wadded quilt, relative air humidity is in 90%-98%, even
Reach air moisture saturation state, causes that moisture film is condensed or formed on the blade of warm indoor growing crop, be the hair of vegetable disease
It is raw to provide favorable environment with sprawling.Such as the downy mildew of cucumber, bacterial angular leaf spot, epidemic disease；The leaf mold of tomato, early late blight
And leek, cucurbita pepo, graw mold of tomato generation and cause harm and have direct relationship.
Relative air humidity is big in greenhouse, in the lower situation of temperature, plastic foil inner wall can be caused to form a large amount of water droplets,
It adsorbs a large amount of dusts and is contaminated, reduce light transmittance, weaken luminous intensity in greenhouse, the decline of vegetables photosynthesis affects
Yield and quality.The water droplet formed on plastic foil is in subacidity and contains a small amount of noxious material, if be dropped on vegetable leaf,
Blade can be made to rot, such as infiltration in the soil, can make the growth retardation of root system.
And in high temperature season, noon, warm indoor air relative humidity was 40% hereinafter, temperature liter since the strong temperature of illumination is high
To 40 DEG C or more, makes the serious dehydration of vegetable leaf and wilt lower heavy, stomata is closed, and photosynthesis is suppressed, and causes blade yellow
Change plant early ageing, causes the vegetable crop underproduction.
Therefore, it is necessary to the humidity to greenhouse to control effectively.
Summary of the invention
The purpose of the present invention is aiming at the shortcomings in the prior art, provide a kind of intelligent adjusting at low cost, effect is good
The method of greenhouse humidity.
The purpose of the present invention is achieved through the following technical solutions: a kind of intelligent method for adjusting greenhouse humidity, it includes
Following steps:
Step 1: temperature inductor, humidity sensor, controller, heat riser are set in greenhouse；
Step 2: humidity sensor senses the humidity information in greenhouse and is transferred to controller, when in greenhouse humidity be higher than it is wet
When spending setting value, controller control starting heat riser heats up；
Step 3: when humidity is less than or equal to humidity set point, and when desired temperature has not yet been reached in temperature, controller control is closed
Heat riser is closed, humidity regulation is completed；
When humidity set point is still greater than in humidity, and when temperature has reached desired temperature, heating dress is closed in controller control
It sets, is manually dehumidified, until humidity is less than or equal to humidity set point, humidity regulation is completed.
The heat riser in step 2 includes solar water heater and heat-dissipating pipe, and heat-dissipating pipe is set in greenhouse, is dissipated
Heat pipe is connected with solar water heater by insulating tube.
The heat riser in step 2 is electric heating heat riser.
Heat riser in step 2 is the fermentation vat being set in greenhouse, and fermenting tank for fermentation promotes greenhouse temperature to increase.
When humidity is lower than humidity set point in greenhouse, controller is sounded an alarm, and if it is noon high-temperature time section, then exists
Sunshade net is covered outside greenhouse；If it is the period other than noon, is then irrigated or sprayed.
The method manually to dehumidify are as follows: on plastic shed soil layer covering by 30-60 parts by weight straw, 30-60 parts by weight wheat bran,
1-5 parts of parts by weight biomass carbons, wooden slag 5-10 parts by weight composition covering, covering with a thickness of 1-3 centimetres.Covering can
It prevents ground moisture from evaporating, reduces air humidity；Irrigation quantity can be also saved simultaneously, often keeps Surface Humid, guarantees that crop is high
It produces.
Vent window is opened in the greenhouse internal and external humidity biggish period at noon to be aerated.
When booth vegetable gathers in, covering is recycled, the covering investment fermentation vat of recycling is fermented.
Beneficial effects of the present invention: the present invention detects the humidity in greenhouse by humidity sensor, wet when finding
When degree is more than humidity set point, the mode for changing temperature of shed to change humidity in canopy is first passed through, is not enough to drop when increasing temperature
When low humidity, then the mode for manually dehumidifying and combining is taken to dehumidify, at low cost, convenient and efficient, intelligence degree of the invention
Height can effectively adjust greenhouse humidity, it is ensured that the growing environment of crops.
