Abstract  

An investigation was carried out to compare the water-saving effects between the rhizospheric irrigation and drip irrigation in an ecological economic forest of red jujube in Xinjiang, China. The soil evaporation was monitored with micro-lysimeters made of PVC. The results showed that: (1) A micro-lysimeter with diameter of 12 cm and height of 15 cm could be used to well monitor the soil evaporation in the studied sites. (2) The soil water loss by evaporation in rhizospheric irrigation was about 50% of that in drip irrigation, and about 11% less than that in the tape-drip irrigation

Key words:  rhizospheric irrigation      drip irrigation      micro-lysimeters      soil evaporation
