英文摘要	Sugar beet (Beta vulgaris L.), as a salt-tolerant plant, has been widely cultivated in saline-alkali soils, e.g. southern Xinjiang of China, due to its effective capability of reducing soil salinity. A two-year field experiment was conducted on drip-fertigated sugar beet under plastic mulch to explore to effects of three irrigation amounts (W-1: 0.60 ETc, W-2: 0.80 ETc and W-3: 1.00 ETc, where ETc is the crop evapotranspiration) and six nitrogen application rates (N-1: 25 kg N ha(-1), N-2: 60 kg N ha(-1), N-3: 120 kg N ha(-1), N-4: 240 kg N ha(-1), N-5: 360 kg N ha(-1) and N-6: 480 kg N ha(-1)) on sugar beet growth, ash salt accumulation, plant Na+, K+, Ca2+ and Mg2+ uptake. The results showed that the year and the two-way interaction of irrigation and nitrogen fertilization had significant effects on dry matter, ash salt accumulation, plant Na+, K+, Ca2+ and Mg2+ uptake, but there was no significant effect of the three-way interaction of year, irrigation and nitrogen fertilization on ash salt accumulation, plant Ca2+ and Mg2+ uptake. The dry matter, ash salt accumulation, Na+, K+, Ca2+ and Mg2+ uptake of N-1 were significantly lower than those of other treatments. Nitrogen fertilization increased the dry matter and ash salt accumulation, Na+, K+, Ca2+ and Mg2+ uptake of sugar beet. The ash salt, K+ and Ca2+ were mainly distributed in the leaf and petiole, while Na+ and Mg2+ were mainly distributed in the taproot. Among the four ions, the average contents of K+ and Na+ were larger in all treatments, which were 1.79 % and 1.62 % in the two years, respectively. The average content of Mg2+ was 0.36 % in all treatments in the two years, and the average content of Ca2+ was lowest in all treatments, which was 0.14 % in the two years. Compared to W-1 and W-2, W-3 decreased the dry matter and ash salt accumulation, plant Na+, K+, Ca2+ and Mg2+ uptake. The ash salt accumulation, plant Na+, K+, Ca2+ and Mg2+ uptake increased with the increasing dry matter accumulation. Based on the response surface methodology, the relationships between water-nitrogen inputs and dry matter, ash salt accumulation, plant Na+, K+, Ca2+ and Mg2+ uptake were established. The results can provide a theoretical basis for the phytoremediation of sugar beet in southern Xinjiang of China and maybe elsewhere with similar arid and semi-arid climates.
