Research,Application And Upgrading Of Intelligent Ventilation Equipment In Solar Greenhouse

Sunlight greenhouse,as the most important agricultural production facility in winter in northern my country,has high thermal insulation and provides a guarantee for the annual production of vegetables.The solar greenhouses in the northern alpine regions have large areas,many types and rapid development,and occupy an important position in the production of vegetables and flowers in winter.The development of sunlight greenhouses has pron(?)ted the development of agriculture and promoted the adjustment of its industrial structure,while increasing the income of farmers and playing a huge role in poverty alleviation.my country's solar greenhouse environmental control is mainly based on manual management,which has problems such as high intensity,low efficiency,low management level,and poor accuracy.In recent years,the intelligent ventilation equipment developed by my country's solar greenhouse has solved the shortcomings of manual management to a certain extent,and provided technical support for the automatic regulation of the greenhouse environment.This research takes the greenhouse intelligent ventilation system as the research object,based on the environmental monitoring cloud platform and the greenhouse intelligent ventilation system information data,and strives to accurately manage the temperature,humidity,CO2 concentration,and maximize the use of light conditions without causing plant freezing damage and high temperature damage.To achieve high crop yields.Through comparison test with traditional methods,it is found that after setting the limit according to different usage requirements,the greenhouse equipped with intelligent ventilation equipment can accurately calculate the greenhouse environment data through the system,and reasonably control the size of the opening of the vent,which basically meets the crop temperature.The requirements of humidity and ventilation are more conducive to the growth and development of crops.This equipment and supporting methods make the crops more productive,and save a lot of manpower and material resources,and provide a scientific basis for the operation of intelligent ventilation equipment.The main research conclusions of this article are as follows:1.On a typical sunny day in winter,the average daily temperature of the test greenhouse increased by 2.9? compared with the control greenhouse,and the average temperature at night increased by 2.8?.In a typical cloudy day in winter,the average daily temperature of the test greenhouse increased by 2.7? compared with the control greenhouse,and the average temperature at night increased by 2.5?.The average daily minimum temperature in January increased by 1?3?.2.The total average daily high humidity of the test greenhouse and the control greenhouse in January was 78.6%and 86.5%,and the humidity in the test greenhouse decreased by 7.9%.Under typical sunny conditions,the maximum humidity of the test greenhouse and the control greenhouse are 86.3%and 76.05%,and the minimum relative humidity of the test greenhouse and the control greenhouse are 46.75%and 37.85%,respectively.The humidity is controlled within a reasonable range under the automatic adjustment of the system.It can not only meet the growth needs of crops in the greenhouse,but also effectively prevent and control diseases and insect pests.3.Under typical sunny conditions in winter,the CO2 concentration in the test and control greenhouses is always higher than that in the outdoor.The average CO2 concentration in the test and control greenhouses is 931 ppm and 641 ppm,an increase of 290 ppm.Under typical cloudy conditions in winter,the CO2 concentration in the test and control greenhouses is always higher than that in the outdoor.The average CO2 concentration in the test and control greenhouses is 1357ppm and 906ppm2 and the test greenhouse is higher than the control greenhouse.4.The average temperature of the ground temperature of the test greenhouse and the control greenhouse under the typical sunny winter is 18.2?,17.1?,an increase of 1.1?.The average ground temperatures of the test greenhouse and the control greenhouse under typical cloudy days in winter were 11.6 and 11.3?,respectively,an increase of 0.3?.In summary,the solar greenhouse equipped with intelligent ventilation equipment can achieve precise control of the environment,making the environmental conditions in the greenhouse suitable for crop growth,and intelligent ventilation equipment suitable for promotion and application in actual production.
