Water and fertilizer irrigation decision making method, device and system and computer readable storage medium

Abstract

The invention discloses water and fertilizer irrigation decision making method, device and system and a computer storage medium. The water and fertilizer irrigation decision making method comprises the steps that a spatial interpolation model is built; sample data is obtained from a database, and the sample data is subjected to normal distribution compliance validation on the sample data; a connection weight of the sample data meeting normal distribution and a to-be-measured point is obtained; a to-be-measured point spatial interpolation result is obtained according to the sample data and theconnection weight; the to-be-measured point spacial interpolation result is compared with an expert knowledge base threshold value, experience deviation of water and fertilizer irrigation is obtained,and the experience deviation serves as execution mechanism input to guide the water and fertilizer irrigation system. Accordingly, the actual requirement state of soil water and fertilizer in a certain area can be worked out by building the spatial interpolation model, globally differentiated irrigation and control are conducted accordingly, and then the water and fertilizer irrigation cost can be reduced, the labor cost is lowered, and economic losses caused by irrigation disorder are reduced.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to a water and fertilizer irrigation decision-making method, device and system, and a computer-readable storage medium. Background technique [0002] With the gradual increase of labor and raw material costs and the continuous penetration of intelligent sensing equipment in the production field of agricultural enterprises, Internet of Things technology and decision support methods have received more and more attention in the field of fine and high-end planting. [0003] At present, the supply and irrigation of water and fertilizer in traditional greenhouse planting has always followed the experience of the grower and the automatic timing irrigation of the machine. The essence of the control of the amount of water and fertilizer is determined by humans and actually operated. Figure 7 It is a schematic diagram of water and fertilizer irrigation control in the related art. Among ...

AI Technical Summary

Problems solved by technology

Since water and fertilizer are important components of cost in the field of fine planting, too much water and fertilizer will be wasted; too little will not meet the normal growth needs of crops, and in extreme cases will cause crops to wither or die, especially in high-end planting fields. High production loss

In order to control the accuracy of water and fertilizer supply, the enterprise has added multiple manual inspections and feeding operations, which has generated a lot of additional labor costs

[0005] Some large-scale high-end planting enterprises have solved the manual problems of operation by investing in large-scale IoT sensor control systems for real-time sampling and water and fertilizer supply. Arranging sensing facilities in all production areas will cause extremely high equipment costs and operation management costs
