Some devices in the present invention are not specifically described, and the specific structure thereof can refer to the Chinese patent CN 105613135B named as “intelligent integrated irrigation system of water, fertilizer, gas and heat in greenhouse”, which is no longer described herein. The present invention further provides an intelligent and precise drip irrigation method for integrated application of water, fertilizer, gas and heat in a greenhouse using the drip irrigation system of the present invention, which includes the following steps:
-11- (1) The power device makes full use of the irrigation interval to perform photovoltaic charging. When the power deficit is monitored in the standby battery, the power device issues a prompt in time through the intelligent control system and charges the standby battery.
(2) The intelligent control system is configured to perform the whole process monitoring, intelligent perception and precise control. When the water deficit is monitored, the decision software automatically generates a calculation result of the required water consumption, and the controller controls the drip irrigation head device to start working according to the calculation result. When the amount of irrigation is met, the irrigation is stopped automatically. During the irrigation, the intelligent control system monitors the operation of the relevant devices. When the filtering device needs to be flushed, the filtering device issues a prompt and flushes automatically.
(3) The intelligent control system monitors the EC/PH value, dissolved oxygen content and temperature in the soil or the cultivation substrate 23. If those values are lower than the required values for crop growth, the fertilizer distributor, the aeration device or the heating device is started.
The above embodiments are only preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements and the like made within the spirit and principles of the present invention shall fall within in the scope of protection of the present invention.
