Abstract:
An operational service system for soil moisture prediction and irrigation decision, applied in a site or throughout the country, was established. With the system, fifteen soil moisture predictions and irrigation decisions,once a week from March to June in 2000 were made. Thirteen of the whole were broadcasted on the programme for the 'Meteorology and Agricultural Information′ of CCTV 7 and served to agricultural production directly. The error analyses showed that average relative error in 0～100cm was the lowest,0～50cm lower and 0～30cm the highest. The distribution of soil moisture that was forecasted was as nearly same as that was measured.
