Problems solved by technology

[0004] In the high temperature season, due to the strong light and high temperature at noon, the relative humidity of the air in the greenhouse is below 40%, and the temperature rises above 40°C, which causes the vegetable leaves to lose water severely and wilt and sink heavily, the stomata are closed, and photosynthesis is inhibited, causing the leaves to lose water. Premature senescence of etiolated plants, resulting in reduced yields of vegetable crops

Embodiment 1

[0022] A method for intelligently adjusting the humidity of a greenhouse, which comprises the following steps:

[0023] Step 1: Install temperature sensors, humidity sensors, controllers, and heating devices in the greenhouse;

[0024] Step 2: The humidity sensor senses the humidity information in the greenhouse and transmits it to the controller. When the humidity in the greenhouse is higher than the humidity setting value, the controller controls to start the heating device to raise the temperature;

[0025] Step 3: When the humidity is less than or equal to the humidity setting value, and the temperature has not yet reached the temperature setting value, the controller controls to turn off the heating device, and the humidity adjustment is completed;

[0026] When the humidity is still higher than the humidity set value, and the temperature has reached the temperature set value, the controller controls to turn off the heating device and perform manual dehumidification until...

Abstract

The invention relates to the technical field of greenhouse planting, in particular to a method for intelligently adjusting humidity of a greenhouse. The method includes that step 1, a temperature sensor, a humidity sensor, a controller and a heating device are arranged in the greenhouse; step 2, the humidity senses information of humidity in the greenhouse and transmits the same to the controller,and the controller controls to start the heating device for heating when the humidity in the greenhouse is higher than a humidity set value; step 3, when the humidity is lower than the humidity set value and temperature does not reach a temperature set value yet, the controller controls to turn off the heating device to complete humidity adjusting; when the humidity is still higher than the humidity set value and the temperature reaches the temperature set value, the controller controls to turn off the heating device, and manual dehumidifying is performed until the humidity is lower than thehumidity set value to complete humidity adjusting. The method is low in cost, convenient, quick, high in intelligent level and capable of effectively adjusting the humidity of the greenhouse and ensuring growth environment of crops.

Description

technical field [0001] The invention relates to the technical field of greenhouse planting, in particular to an intelligent method for adjusting the humidity in a greenhouse. Background technique [0002] Due to the large amount of irrigation water and high soil humidity in greenhouses, the evaporation of ground water and the transpiration of vegetable crops are also large. Under the airtight conditions with relatively small space, stable airflow and covered with plastic film, it is not easy to exchange gas with the outside world, so that the relative humidity of the air in the greenhouse is relatively high, especially at night when the grass curtains and quilts are covered, the relative humidity of the air is relatively low. At 90%-98%, it even reaches the saturated state of air moisture, causing condensation or water film formation on the leaves of crops growing in the greenhouse, providing a favorable environment for the occurrence and spread of vegetable diseases. Such ...
