Influences of partial root-zone irrigation on the growth and development，yield，and quality of nectarine in greenhouse

The influences of partial root-zone irrigation on the growth and development，yield，and quality of nectarine in greenhouse were studied.The results show that alternative partial root-zone irrigation（APRI）and fixed partial root-zone irrigation（FPRI）can inhibit the new shoots growing and advance the maturity of fruits than conventional irrigation（CI）.The average fruits weight and fruits rigidity obtained in APRI and FPRI treatments are reduced，but the yield is not influenced，and the total soluble solids is increased.Water saving of 50% is achieved in APRI and FPRI，and water using efficiency（WUE）is increased.Compared with FPRI，the average fruits weight，yield，total soluble solids and water using efficiency of APRI are all increased，except of fruit rigidity.
