摘　　要：在甘肃庆阳乔化红富士果园开展试验,研究水肥一体化技术条件下不同管理措施对土壤水分及苹果产量的影响,旨在为科学制定乔化果园水肥管理方案提供依据。结果表明:不同处理0-20 cm土层含水量为14.6%-22.3%,土壤水分增长率为1.1%-32.4%,最大减少率为5.6%;21-40 cm土层含水量为14.2%-20.6%,增长率为2.1%-22.5%,最大减少率为1.7%;41-60 cm土层含水量为13.6%-20.0%,增长率为0.5%-30.4%,最大减少率为6.7%。不同处理苹果产量为1123.6-1393.4 kg/667 m^(2),产量最高的是T_(6)处理,为1393.4 kg/667 m^(2),较CK增长了24.0%。果树开花期0-20、21-40、41-60 cm土层含水量与产量的相关性最显著,相关系数分别为0.227、0.640、0.513。A field experiment was conducted in orchards of arboroid Fuji apple trees in Qingyang,Gansu to study the effects of integration of water and fertilizer on soil moisture and apple yield,so as to provide a basis for scientifically formulating water and fertilizer management plans for the orchards.The results showed that under different treatments,the water content of 0-20 cm soil layers varied from 14.6%to 22.3%,with the increasing rate of soil water content from 1.1%to 32.4%,and the maximum decreasing rate of 5.6%;the water content of 21-40 cm soil layers varied from 14.2%to 20.6%,with the increasing rate from 2.1%to 22.5%,and the maximum decreasing rate of 1.7%;and the water content of 40-60 cm soil layers varied from 13.6%to 20.0%,with the increasing rate of soil water content from 0.5%to 30.4%,and the maximum decreasing rate of 6.7%.The yields of apples under different treatments ranged from 1123.6 kg/667 m^(2) to 1393.4 kg/667 m^(2),with the highest yield of 1393.4 kg/667 m^(2) under T_(6),which was 24.0%higher than that of CK.The correlation between yields and soil water content in 0-20 cm,20-40 cm and 40-60 cm soil layers was the most significant at the blooming stage,and the correlation coefficients were 0.227,0.640 and 0.513,respectively.
