The experiment was conducted at the experimental base of red dates in Mengcha Village，Mizhi County，Yulin City，Shaanxi Province.The average annual rainfall in the test site is 451.6 mm.The soil on the test site is dominated by loess soil and is relatively poor.The drip irrigation quota for the trial period was 135 m3/ha.In 2012，irrigation was conducted twice on May 15 and June 10.The basic physical properties of the soil are shown in Table 1.The p H was 8.6；the bulk density was 1.21 g/cm3；the content of available potassium（101.9 mg/kg）was medium；and the contents of alkali-hydrolyzable nitrogen（34.73 mg/kg），organic matter（2.1 g/kg）and available phosphorus（2.90 g/kg）were low.There was a loss of microelements in the soil[16].In the test soil，the contents of available iron，available zinc，available manganese and available copper were 6.13，0.13，5.80 and 0.74 mg/kg，respectively.
