Example six:
the utility model provides an agricultural planting greenhouse and a temperature regulation method thereof, which take potatoes as crops in the embodiment, and the temperature of different depths needs to be detected as the potatoes grow deeper and deeper in the growth process of soil, and the following is a specific embodiment.
Firstly, inputting data of 50% -70% of the humidity of the proper soil of potatoes and a proper temperature range of 15 ℃ -25 ℃ into a computer, inserting a temperature sensor 253 and a humidity sensor 254 on a detection probe 25 into the soil, firstly detecting the humidity in the soil through the humidity sensor 254, wirelessly transmitting the detected humidity to the computer in a regulating and controlling device 3 through a data transmitter 21 for analysis and comparison, and if the detected humidity is lower than the proper soil humidity by 50%, controlling the regulating and controlling device 3 to perform irrigation operation by the computer, specifically spraying a water source which is regulated to the temperature range of 15 ℃ -25 ℃ through a semiconductor chip in a water tank 31 on spinach through a nozzle 351, humidifying the water source and controlling the temperature of the water source to be close to the proper temperature;
after irrigation operation is carried out on potatoes for a period of time or when the detected humidity is not lower than 50% of the proper soil humidity, the temperature in the soil is detected through the temperature sensor 253, the detected temperature is wirelessly transmitted to a computer in the regulating and controlling device 3 through the data transmitter 21 for analysis and comparison, if the temperature is lower than 15 ℃ of the proper temperature minimum value or higher than 25 ℃ of the proper temperature maximum value, the temperature regulation is carried out, specifically, the gas controlled in the proper temperature range of 15-25 ℃ in the temperature control box 32 is directly transmitted to the periphery of spinach through the nozzle 351, so that heat consumption is reduced, and the problem of large temperature difference between different areas of the same greenhouse is avoided.
Tubers of potatoes grow deeper and deeper in the process of growing, because the potatoes find nutrients and moisture in the soil, the root system of the potatoes continuously extends, so that the stems and new tubers grow gradually downwards, at the moment, a detection probe 25 is required to be inserted deeper for detecting temperature, a computer is used for controlling the rotation of a rotary winding column 221 to extend a data cable 20, so that the detection probe 25 can be inserted deeper, and thus, a temperature sensor 253 and a humidity sensor 254 can detect data of the position corresponding to the depth of the potatoes, and the temperature regulation method is repeatedly applied for detection.
The first step, the computer for data collection and analysis of the regulating and controlling device 3 is used for inputting the proper temperature range and proper soil humidity range determined according to the crop type and the growing period as the preset value, and simultaneously the length of the data cable 20 which extends out is controlled by rotating the winding column 221 according to the growing period, so that the height of the temperature sensor 253 at the tail part of the detecting probe 25 from the ground or the depth in the soil is controlled;
secondly, the data transmitter 21 sends the soil humidity data detected by the humidity sensor 254 to a computer for data collection and analysis in the regulating device 3, if the soil humidity is lower than the lowest value of a proper soil humidity range of a preset value, the regulating device 3 controls the water tank 31 to open and regulate the valve of the main pipeline 33, water in the water tank 31 flows into the regulating sub pipeline 35 through the main pipeline 33, flows into the regulating sub pipeline 35 to be sprayed on crops through the nozzle 351 to improve the humidity, closes the valve of the main pipeline 33, and uses air pressure to empty the water in the main pipeline 33 and the regulating sub pipeline 35 through the air pipe 34;
third, after spraying water in the second step or when the detected humidity is higher than the preset value, the data transmitter 21 transmits the temperature detected by the temperature sensor 253 to the computer for data collection and analysis in the control device 3, and if the temperature is lower than or higher than the minimum value and the maximum value of the proper temperature range of the preset value, the gas controlled at the proper temperature in the temperature control box 32 is delivered into the main control pipe 33 through the gas pipe 34, and then the gas is released near the crops through the nozzle 351 of the sub control pipe 35, so that the temperature is controlled within the preset proper temperature range.
