Abstract

The invention relates to an accurate drip irrigation and fertilization system which comprises a monitoring system, a fertilizer and liquid mixing system and a drip irrigation system, wherein the fertilizer and liquid mixing system is connected with the drip irrigation system by a pipeline, the monitoring system is connected with the fertilizer and liquid mixing system and the drip irrigation system respectively by lines, the monitoring system consists of an industrial control computer that is connected with a programmable logic controller by a Zigbee wireless transceiving module, and the programmable logic controller is connected with an AD input module and a DA output module. With the accurate drip irrigation and fertilization system, an agricultural producer can realize full-automatic operation during the drip irrigation and fertilization processes, not only can know information of producing process in real time, but also can accurately carry out fertilization decision so as to achieve the effects of avoiding fertilizer waste and saving labor; and as data transmission adopts a wireless mode, the monitoring computer and a field controller are separated, and the problem that a communication cable of the system is not easy to be laid in the field can be effectively solved.

Description

technical field [0001] The invention relates to a fertilization system, in particular to a precision drip irrigation and fertilization system. Background technique [0002] Drip fertilization is a kind of liquid fertilization. It is a method of dripping the fertilizer liquid mixed with solid fertilizer or liquid fertilizer into the root soil of crops at the same time with the help of the existing drip irrigation system. After the fertilizers needed by crops during the growth period are dissolved in water, they are evenly applied near the roots of the crops along with the drip irrigation water for direct absorption and utilization by the roots of the crops, which can improve the management of water and nutrients, and greatly improve the coupling effect of water and fertilizer and the efficiency of water and fertilizer use , Reduce yield variation, increase yield and increase return, also reduce water and nutrient leakage, and reduce environmental pollution from fertilization....
