5. The control method of the culture environment control system of claim 1, wherein when the indoor temperature meets the first preset condition corresponding to the heating mode, the first preset condition is: the indoor temperature is greater than or equal to the difference between the indoor target temperature and the first control temperature difference value.
6. The control method of the culture environment control system according to claim 1, wherein when the indoor temperature meets the first preset condition corresponding to the ventilation mode, the first preset condition is: the indoor temperature is greater than or equal to the difference between the indoor target temperature and the first control temperature difference value, and the indoor temperature is less than or equal to the sum of the indoor target temperature and the first control temperature difference value.
7. The control method of the cultivation environment control system as claimed in claim 1, wherein when the indoor temperature meets the first preset condition corresponding to the cooling mode, the method comprises the following steps: the indoor temperature is greater than or equal to the sum of the indoor target temperature and the first control temperature difference value.
8. The control method of the culture environment control system according to claim 4, wherein the step of judging whether the indoor temperature meets the second preset temperature condition corresponding to the current operation mode specifically comprises the steps of: judging whether the indoor temperature is greater than or equal to the sum of the indoor target temperature and the second control temperature difference value or not when the refrigeration mode is operated; judging whether the indoor temperature is less than or equal to the difference between the indoor target temperature and the second control temperature value when the heating mode is operated; and judging whether the indoor temperature is less than or equal to the difference between the indoor target temperature and the second control temperature difference value or whether the indoor temperature is greater than or equal to the sum of the indoor target temperature and the second control temperature difference value when the ventilation mode is operated.
9. The control method of the aquaculture environment control system according to claim 2, wherein the step of opening the small window of the aquaculture house and controlling the opening of the small window according to the airflow speed at the small window specifically comprises the following steps: when the flow velocity of the small window airflow is greater than the sum of the small window wind velocity adjusting threshold value and the flow velocity control deviation value, increasing the opening degree of the small window; and when the flow velocity of the small window airflow is smaller than the difference between the small window air velocity adjusting threshold value and the flow velocity control deviation value, reducing the opening degree of the small window.
10. An environmental cultivation control system, characterized in that the carbon dioxide concentration in a cultivation house is reduced by using the control method of the environmental cultivation control system as claimed in any one of claims 1 to 9.
