摘  要：
以6a生"富士"苹果园为研究对象,采用灌溉的方式,将苹果树树冠下土壤的表层(0~20cm)、根系集中层(0~50cm)和深层(0~80cm)土壤达到田间持水量后覆盖黑色地膜,研究了不同土壤层次灌水后覆黑膜对黄土高原旱作苹果园的蓄水保墒效果、树体生长和产量的影响。结果表明:在苹果树生育期内,灌水使根系集中层达到田间持水量后,覆膜处理的水分利用率和产量最高,平均产量较对照提高58.0%,水分利用效率提高44.7%,比对照节水61.9mm,该处理的光合特性最佳。综合考虑,灌水使根系集中层达到田间持水量后覆膜是黄土高原区苹果园旱作中节水灌溉的高效栽培模式,适合当地生产需要。

摘  要：
Taking 6-year-old‘Fuji'apple tree orchard as experiment object,the effects of plastic film mulching by irrigating the surface layer(0~20cm),root concentration layer(0~50cm)and deep layer(0~80cm)on soil water conservation,growth and yield of apple trees were studied.The results showed that during the growing period of the apple tree,making the 0~50cm soil layer reached the field capacity and covered(W2F)processed the highest water use efficiency,W2F treatment had the highest yield,average yield was increased by 58.0% than that of CK,WUE was 44.7% higher than that of CK,the water-saving amount was 61.9mm higher than that of CK,W2F treatment had the best photosynthetic characteristics.Comprehensive consideration,making the 0~50cm soil layer reached the field capacity and covered was an effective measure in the apple orchard in Loess Plateau.
