Abstract:Some problems about the calculation of virtual water content of agricultural products were analyzed,and a corresponding improved method was proposed.Crop water consumption characteristics and the composition of the total virtual water production were discussed, and based on the water balance method,the calculation method of total virtual water production under deficit irrigation were proposed.The results showed that different methods have little differences for the calculation of the total production of vir...
Keywords:agricultural products  virtual water content  method improvement  water balance
