  • Patent number: 11690333
    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.

  • Publication number: 20150135991
    Abstract: A method of dissolving cellulose, comprising: firstly heating and activating the cellulose by using a heating apparatus, and then dissolving by using a solvent. The temperature of the heating and the activating is 130° C.-270° C., the time period of the heating is 0.1-100 hours, and the solvent is an aqueous solution including 6 wt %-12 wt % sodium hydroxide and 0.1 wt %-6 wt % zinc oxide. The method of dissolving comprises: heating and activating the cellulose with a degree of polymerization of DP=300-700, dispersing the cellulose into the solvent, and freezing under a temperature of ?10˜-30° C. for 0.1-50 hours; then unfreezing under a condition of no more than 32° C., and standing or stirring by machine during the process of unfreezing so as to dissolve and obtain a cellulose solution with a concentration of 3 wt %-12 wt %. The obtained cellulose solution has a good solubility and stability that maintains a relatively good stability after being stood under a temperature of ?8 to 32° C. for a few days.
