Embodiment Construction

[0017] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] In matrix cultivation, automatic irrigation is achieved by accumulating light radiation to achieve precise irrigation. Specific according to every 200-300 joules / cm 2 Irrigate 1 time, need to irrigate 10-15 times a day, generally start the first drip irrigation 2 hours after sunrise (photosynthesis has just started, satisfy transpiration), and last irrigation 2 hours before sunset (substrate dry water, for evening plants Respiration), the amount of each irrigation and irrigation time in the middle depends on the cumulative light radiation intensity, which is directly related to the cumulative light radiation.

[0019] refer to figure 1 , an automatic irrigation device that can measure cumulative optical radiation, including a cumulative optical radiation intensity sensor 1, a central controller 2, a ...

Abstract

The invention discloses an automatic measurable accumulated light radiation irrigation device and method. The device comprises an accumulated light radiation intensity sensor, a central controller, awater pump, a pipeline electromagnetic valve, a conveying system and a remote control terminal, wherein the accumulated light radiation intensity sensor, the remote control terminal, the water pump and the pipeline electromagnetic valve are respectively connected by taking the central controller as a center; the accumulated light radiation intensity sensor, the water pump and the pipeline electromagnetic valve are in wired transmission with the central controller; and the central controller is in wireless transmission with the remote control terminal through GPRS (general packet radio service)communication. By adopting the device and method, interconnection of irrigation and accumulated light radiation sensors, real-time monitoring, feedback and intelligent judgment on an accumulated light radiation intensity are achieved in the irrigation and fertilization process, schemes can be modified, and precise control on irrigation and fertilization can be executed. The accumulated light radiation intensity is directly associated with evapotranspiration of a crop, irrigation starting time is recommended, and an irrigation amount can be accurate and in-time.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to an automatic irrigation device and method capable of measuring accumulated light radiation. Background technique [0002] At present, the time and amount of irrigation in the irrigation process mainly rely on human observation of soil and crop appearance, and empirical judgment, which cannot realize real-time precise irrigation control at all; scientific irrigation can be realized through soil moisture monitoring. The existing technology, one is to use artificial soil drying method to monitor soil water content, although moisture analysis can be carried out, but it is seriously lagging behind, and it is impossible to guide irrigation in time; the other is to adopt automatic monitoring irrigation, and most of them use soil moisture sensors to monitor Soil water content is used to interpret and recommend irrigation time and irrigation amount, but there are generally low correlatio...
