  • Method for forecasting an agricultural irrigation water requirement
    Patent number: 11209574
    Abstract: A method for forecasting an agricultural irrigation water requirement includes: selecting a baseline period and crops each with a sown area larger than a set proportion as typical crops; calculating an irrigation water quota of the typical crop during a growth stage according to meteorological information; obtaining ten-day rainfall in a water-saving area from weather stations; and calculating effective rainfall in a sown region of the typical crop based on the ten-day rainfall; calculating an irrigation water requirement per unit area of the typical crop; and determining whether the irrigation water requirement per unit area of at least one typical crop is greater than an average of actual irrigation water usage per unit area measured in consecutive years, if yes, correcting the irrigation water requirement per unit area of all typical crops according to actual irrigation water usage; otherwise calculating a total water requirement for a next year.
