The mechanism of fertilization in increasing water use efficiency(WUE) has been studied by the field experiments with nitrogen, phosphorus and farm manure in the east area of subhumid lands prone to drought, Gansu province, from 1991 to 1995. The experiment results indicate: The winter wheat root growth can be stimulated by fertilization, especially by combination of nitrogen and phosphorus, so it may be extended the space of water uptake by roots. When nitrogen and phosphorus couple, they may supplement one another in the growth stages and the function. Compared with no fertilization, on an average, the evapotranspiration of the treatments with fertilization increased by 5.4%, but the yields and WUE increased by 92 8% and 79 7%,respectively. Fertilization may stimulate the growth of canopy of winter wheat, increase the amount of transpiration and decrease the amount of evaporation, so it may enhance the ratio of transpiration to evaporation, WUE and productivity of water.

1991 ~1995 年,在陇东半湿润易旱地区以冬小麦为供试作物,通过氮、磷、有机肥三因素试验从生态学角度探讨了施肥对提高水分利用效率的机理。结果表明,施肥,尤其是氮磷化肥配施,可明显促进冬小麦根系生长,扩大觅水空间;氮磷化肥配施具有时效互补性和功能互补性;与不施肥处理相比,施肥处理蒸散量仅提高了54 % ,而产量和水分利用效率却分别提高了928 % 和797 % ;施肥促进了冬小麦冠层发育,增加了蒸腾量,而减少了蒸发量,从而提高了腾/发比,使水分利用效率及水分生产力大幅度提高。

锡林河流域栗钙土具有典型的草原土壤特征。土壤水分是生产力主要的制约因素,水分状况受到天然降水及土壤性状的影响,水分特征曲线研究表明,土壤持水力与质地及有机质含量有密切关系,水分有效性主要取决于土壤含水量及释水性。土壤水分动态有明显的阶段性变化规律。地形、母质、地表状况、质地及剖面特征决定了水分空间变异情况,长期低水平的水分循环是栗钙土生产力不高、不稳的主要原因
