摘  要：
以氮、磷、钾含量比例为1∶1∶1的化学肥料为肥源,在初夏对嘎拉苹果施不同量(0.25、0.5、0.75、1.0 kg/株)的肥料,研究初夏追肥对渭北地区嘎拉苹果树体营养生长和果实品质的影响。结果表明:各施肥水平处理均能显著提高叶面积和叶绿素含量,促进新梢生长,处理5(N∶P∶K=1∶1∶1 kg/株)的叶面积比对照高18.95%,叶绿素含量比对照高36.08%,新梢长度和新梢基径比对照增加20%～30%;各施肥水平处理也提高了果实品质,处理5在提高单果重、硬度、可溶性固形物、可滴定酸含量方面的效果最佳。综合分析,采用处理5的追肥模式最好。

摘  要：
The experiment was carried out with different fertilizing amount(0.25,0.5,0.75,1.0 kg/plant)at early summer.Chemical fertilizer(N∶P∶K=1∶1∶1)had been used to identified the effect of fertilizer application at early summer on growth and quality of Gala apple in Weibei region.The results showed that fertilizer application at different amounts obviously improved leaf area,chlorophyll content and hastened stem growth.In treatment 5(N∶P∶K=1∶1∶1,1 kg/plant),the leaf area had been increased by 18.95% compared to the CK,the chlorophyll content had been increased by 36.08%,the stem growth had been increased by 20%～30%.Each treatment can improve the fruit quality and treatment 5 did well at improving weight of single fruit,firmness,soluble solids content,titratableacid.To conclusion,treatment 5 was the moderate model of fertilizer application in Gala apple orchard at Weibei region during early summer.
