Irrigation fertilization system based on cloud computing technology

Abstract

The invention discloses an irrigation fertilization system based on a cloud computing technology. The system comprises a data collection module, a data analysis module, a controller, a signal execution module, a pesticide amount analysis module, a pesticide amount collection module, a pesticide adding action module, a concentration acquisition module and a signal indicating module. The system generates various signals according to growth information of plants before spraying and fertilizing and controls spraying and fertilizing equipment to work according to the signals for adjustment to reach the appropriate spraying and fertilizing position and spraying and fertilizing amount, and therefore the purpose of improving the spraying and fertilizing effect is achieved; meanwhile, the spraying and fertilizing amount, the pesticide remaining amount and the weather and temperature conditions are subjected to formulation analysis together to judge whether or not pesticide adding is needed, the pesticide adding amount and the water adding amount are reasonably controlled in a liquid storage tank for pesticide adding according to the combination of the concentration change caused by the weather and temperature conditions and the growth information of the plants at this time, so that the growth rate and nutrient ratio of all the plants are more balanced.

Description

technical field [0001] The invention relates to the technical field of fertigation systems, in particular to a fertigation system based on cloud computing technology. Background technique [0002] The process of fertilizer entering the field with irrigation water is called fertigation, that is, while drip irrigation or subsurface drip irrigation, fertilizer is applied to plants according to the nutrient needs and climatic conditions of each stage of plant growth. And fertigation can be roughly divided into three categories: surface irrigation, underground irrigation and injection irrigation. [0003] And in the document whose publication number is CN108934366A, it is only based on the meteorological sensing device to detect the rainfall information, and the controller controls the opening of the automatic door to collect rainwater. At the same time, the controller also controls the opening of the irrigation solenoid valve and the fertilization solenoid valve according to the...

Problems solved by technology

[0003] And in the document whose publication number is CN108934366A, it is only based on the meteorological sensing device to detect the rainfall information, and the controller controls the opening of the automatic door to collect rainwater. At the same time, the controller also controls the opening of the irrigation solenoid valve and the fertilization solenoid valve according to the soil moisture condition. Timely irrigation and fertilization of the soil to be irrigated; and combining it with the existing fertigation system, it is still difficult to adjust the location and amount of fertilization according to the growth of the plants before spraying and fertilization, so as to improve the spraying rate. Fertilization effect; and it is difficult to consider the impact of fertilization amount and drug residue and drug volatilization caused by weather factors together, and combine the plant growth status and drug concentration at this time to rationally add drugs and water, so that each plant The growth rate and nutrient ratio are more balanced
