Abstract: A system and method for optimal allocation of agricultural water based on water consumption control are provided. The system includes a data management module, configured to store and manage data related to water allocation; a basic data statistics module, configured to take statistics on various stored data; an agricultural evapotranspiration (ET) calculation module, configured to calculate an agricultural ET based on the stored data and statistical data; and a water resource allocation module, configured to generate a corresponding water resource allocation scheme based on an agricultural ET of each water consumption unit and corresponding data. Surface water and groundwater are jointly allocated to reduce groundwater exploitation, increase groundwater recharge, reduce invalid water loss and consumption in a carrying and allocation process, and improve an output benefit of agricultural water supply.

Abstract: The invention belongs to the technical field of trace detection, and discloses a heavy metal trace detection method and application thereof. The detection method; comprising the following steps: preparing a quality sample; mixing the quality sample with the sample to be tested according to a specific proportion; using X-ray fluorescence spectrometer to detect trace heavy metals; and using standard curve to realize quantitative analysis of heavy metals. For the purpose of detecting heavy metal elements in tea, the application of this invention can shorten the detection time, avoid the use of a large amount of acid liquor, improve the environmental protection performance, and lower the detection cost, moreover, the obtained standard curve by this invention has high correlation and accurate detection results.

Abstract: An agricultural water-saving planning method based on a remotely-sensed ET includes the following steps: S1: determining an agricultural target ET of a crop; S2: establishing an agricultural water-saving planning model based on the agricultural target ET of the crop, and planning a planting area of the crop of a whole county to obtain a county-level planning scheme; and S3: decomposing the county-level planning scheme to township-level governments and further to village-level units for execution and supervision. The new method realizes the balance between real regional agricultural water consumption and actual water supply.

Abstract: According to an irrigation method based on water usage characteristics and real-time weather condition during different crop growth stages, whether the crops are in a shortage of water in the growth is determined based on an actual soil water content, a water usage amount of the crops during the given growth stage, and a rainfall amount during the next day. If the shortage of water occurs, the actual water usage amount of the crops is calculated, and a water pump can be self-adaptively turned on to water the crops and an administrator is informed when the reservoir has an insufficient water storage, according to the relation between the water storage amount of the reservoir and the actual water usage amount.
