Abstract：Trace quantity irrigation is a new irrigation technology based on soil capillary force principle and membrane filtering technology. A study was carried out to investigate the effects of trace quantity irrigation on crop yield, dry matter partitioning and water use efficiency of spherical fennel under greenhouse conditions. Drip irrigation was selected as control treatment. The results showed that yield and dry weight of edible part (bulb) and aboveground part (stem and leaf) were significantly higher under trace quantity irrigation than those under drip irrigation, while the total water consumption was significantly lower than that under the latter. Water use efficiency under trace quantity irrigation was 23 times as much as that under drip irrigation.
