Embodiment Construction

[0027] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples serve to illustrate the present invention, but do not limit the scope of the present invention.

[0028] like figure 1 As shown, the root system partition alternate irrigation controller according to the present invention includes: a signal acquisition module 10, which is arranged in the irrigation ditch 00 on both sides of the crop, and is used to collect soil moisture content information; a signal conversion and data processing module 20, which uses According to the received information collected by the signal collection module, the alternate irrigation of crops is controlled; the parameter setting module 30 is used to set the parameters of the signal conversion and data processing module.

[0029] The signal acquisition module is a soil moisture sensor; a plurality of soil moistur...

Abstract

The invention relates to an alternate partial root-zone irrigation controller and an alternate partial root-zone irrigation system. The controller comprises signal acquisition modules, a signal conversion and data processing module and a parameter setup module, wherein the signal acquisition modules are disposed in irrigation gutters on two sides of crops and used for acquiring information of soil moisture, the signal conversion and data processing module is used for controlling gutter spaced alternate irrigation of the crops according to the information received by the signal acquisition modules, and the parameter setup module is used for setting parameters of the signal conversion and data processing module. The alternate partial root-zone irrigation controller is simple in structure, capable of automatically alternately irrigating the crops under full intelligent control by man-machine communication, signals from the sensors and drive of a single chip microcomputer. The alternate partial root-zone irrigation controller simple in structure is laborsaving, timesaving, cost-saving, convenient in operation and easy for large-scale popularization. In addition, traditional electromagnetic control valves are substituted by alternate irrigation valves, so that the alternate partial root-zone irrigation system is simple, cost-reducing and reliable in operation.

Description

technical field [0001] The invention belongs to the technical field of irrigation, and in particular relates to a root partition alternate irrigation controller and an irrigation system thereof. Background technique [0002] In 1996, based on the principle of water-saving irrigation technology and the root signal theory of crops' perception of water shortage, Kang Shaozhong et al. proposed the root system zoning alternate irrigation technology to actively control the moisture status of the crop root zone soil in a certain area in the horizontal or vertical section, so that the crop root zone There is always a part of the growth in a dry or relatively dry environment, which limits the water absorption of the root system. At the same time, through artificial control, the root system alternately appears in the dry area of ​​the horizontal or vertical section, so that the root system in the dry area generates a water stress signal and transmits it to the leaf stomata. In this wa...
