[0016] The invention relates to a water-saving irrigation method based on the seedling condition and soil moisture of winter wheat. The water-saving irrigation method selects representative plots in the main planting areas of crops according to a certain proportion according to crop types and soil types, and regularly fixes Monitoring soil moisture and crop growth, combined with crop water requirements and meteorological conditions, according to soil moisture and crop drought grading evaluation indicators, analyze and determine farmland moisture and crop drought, and propose specific irrigation guidance programs. The soil moisture content index that affects the growth and development of crops is based on how much water is actually stored in the soil and can be used by crops to determine the moisture status of the soil. The irrigation method in the present invention adopts the percentage of soil moisture that accounts for the field water capacity, That is, the relative soil mois...
