英文摘要	We determined the effects of attapulgite clay additions to sandy soils on maize yield and water-fertilizer use efficiency to evaluate a new method for enhancing productivity in newly-reclaimed farmlands in the oasis. The 2-year field trial included six treatments: no fertilizer, single fertilizer application (N-P2O5-K2O at 320-240-200 kg center dot ha(-1)), and combined applications of different amounts of attapulgite clay and fertilizer (attapulgite powder at 1500, 3000, 6000 kg center dot ha(-1)), 20% fertilizer reduction (256-192-160 kg center dot ha(-1)) and attapulgite powder at 6000 kg center dot ha(-1). The results showed that maize yield increased by 4.9-14.9% and above-ground biomass increased by 6.1-32.3% with the application of 1500, 3000, and 6000 kg center dot ha(-1) of attapulgite powder compared with the single application of fertilizer. With a combined application of a 20% reduction in fertilizer and 6000 kg center dot ha(-1) attapulgite powder, maize yield increased by another 6.6%. Maize irrigation-water productivity (MIWP) increased by 0.03-0.13 kg center dot m(-3), and nitrogen use efficiency (NUE), agronomic efficiency (AE(N)) and partial productivity factor of nitrogen (PFPN) increased by 10.8-54.0, 15.5-49.5, and 4.6-14.8%, respectively, compared with no attapulgite application. The contribution rate of fertilizer to maize yield increment improved by 10.0-30.1% with attapulgite application. The attapulgite clay application increased the field water capacity of sandy soils, nutrient retention in the 0-40 cm soil layer, and reduced nutrient leaching losses to deeper soils, thus improving water-fertilizer use efficiency. In Linze County, the abundant reserves of attapulgite clay may be used as a regular application in sandy farmlands in newly-reclaimed oases for a new promising way to rapidly improve sandy soil structure, enhance water-fertilizer use efficiency, and increase crop yields.
