Description

technical field [0001] The invention relates to a fertilization and water supply control system and method, in particular to an automatic fertilization and water supply control system and method. Background technique [0002] Precision agriculture is a new trend in the development of agriculture in the world today. It is supported by information technology and implements a complete set of modern agricultural operation technology and management system in positioning, timing and quantity. Its basic meaning is to finely and accurately adjust the input to crops according to the changes in the soil conditions of crop growth, so as to achieve the purpose of obtaining maximum yield and maximum economic benefit with the least and most economical input. [0003] Patent No. ZL 200710175341.2, the Chinese patent titled "A Control System and Method for Variable Fertilization" is a precision agriculture based on geographic information system, global satellite positioning system, remote s...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides an automatic fertilization and water supply control system and method, aiming at the traditional fertilization method that wastes water resources, wastes manpower and material resources, cannot fertilize and water crops in time according to the needs of crops, and the existing automatic fertilization system only monitors soil EC value without temperature compensation, etc. Disadvantages, through the analysis of the root soil during the growth of crops, the control system for automatic on-demand fertilization is designed. This system can automatically fertilize crops by drip irrigation, which can save water, electricity and labor costs.
