Abstract: Disclosed is an intelligent monitoring method for soil moisture status based on remote sensing technology, including the following steps: dividing a monitoring region into a plurality of sub-regions by a processing end, acquiring image data of various sub-regions on the basis of remote sensing satellites, acquiring multi-source data related to soil moisture status of the monitoring region on the basis of sensor devices, and pre-processing the image data and the multi-source data; comprehensively analyzing the image data and the multi-source data, and assessing soil moisture status of the various sub-regions; and comprehensively analyzing overall soil moisture status of the monitoring region according to the soil moisture status of the various sub-regions. The soil moisture status of the monitoring region is assessed after the multi-source data is comprehensively analyzed by the monitoring method, bringing about a more comprehensive and accurate analysis.

Abstract: A drip irrigator for film-mulching drip irrigation, a film-mulching irrigation assembly and an installation method of the film-mulching irrigation assembly are provided. The drip irrigator includes a main pipeline, branch pipes and emitters. Emitter are arranged on an upper surface of the branch pipe and communicate with the branch pipe, water outlet holes are formed in inner and outer ring walls of an annular pipeline, and an opening end of the main pipeline communicates with a water conveying pipeline. By arranging emitters on the upper surface of each branch pipe, the emitters can be effectively prevented from being blocked by wet soil. Meanwhile, the water outlet holes can perform the drip irrigation to the ground simultaneously, and the overall efficiency of drip irrigation to the soil is guaranteed.
