Water-fertilizer integrated intelligent control system for irrigation based on soil moisture measurement and control method thereof

Abstract

The invention relates to a water-fertilizer integrated intelligent control system for irrigation based on soil moisture measurement and a control method thereof. The control system is composed of a soil moisture information collection station, a central control unit storing soil moisture information, and an irrigation unit. The soil moisture information collection station is connected with a first input terminal of the central control unit; and a first control terminal of the central control unit is connected with the irrigation unit. The control system is characterized in that an illumination intensity detection circuit, an air temperature and humidity detection circuit, and a fertilization unit are arranged in the system; the illumination intensity detection circuit and the air temperature and humidity detection circuit are connected with a second input terminal of the central control unit; and a second output terminal of the central control unit is connected with the fertilization unit. The control system and method have the following beneficial effects: on the basis of intelligent control of the central control unit, effects of water saving, fertilizer reduction, high yield, and high efficiency are realized; the water and fertilizer wasting is reduced; the fertilizer and water utilization rates are improved; and thus effects of high yield and high efficiency of crops can be realized.

Description

technical field [0001] The invention belongs to the technical field of upland crop planting, relates to the water and fertilizer irrigation technology of corn and wheat, and specifically relates to an intelligent control system and control method for moisture measurement and irrigation water and fertilizer integration. Background technique [0002] In the planting technology of corn or wheat, the water and fertilizer application scheme has a crucial influence on the yield. With the improvement of the degree of automation, some automation schemes have appeared in the prior art. For example, the patent No. 201310076636.X for the wireless intelligent irrigation system and method patent based on moisture information mainly discloses the method of automatically controlling the irrigation unit through the moisture information, which can save a certain amount of manpower. However, when planting corn or wheat, irrigation is only one of the factors that affect the yield, and the amo...

AI Technical Summary

Problems solved by technology

However, when planting corn or wheat, irrigation is only one of the factors that affect the yield, and the amount of fertilizer added and the ratio between it and water are also very critical factors. If there is no reasonable proportioning scheme and quantitative application of fertilizer , the yield and quality of corn and wheat will not reach the ideal state

Patent No. 201320868210.3 discloses a wireless control irrigation system, which only solves the problem of automatic irrigation, and cannot reflect the fertilization plan

In the existing technology, adding fertilizers is generally done manually, which is also an important factor affecting the farmers' planting recovery ratio under the current situation of extremely high labor costs.

At the same time, due to manual fertilization, the time of fertilization and irrigation cannot be synchronized, and the ratio of fertilization and irrigation can not be effectively controlled, which will eventually lead to serious impact on the yield and quality of crops
