采用地下灌注和叶面喷施2种施肥方法，研究了腐植酸水溶肥对苹果树生长发育及果实产量和品质的影响。结果表明：地下灌注组以处理1(常规施肥+施用90 k g/h m2腐植酸水溶肥)效果最好；叶面喷施组以处理4(常规施肥+叶面喷施6次腐植酸水溶肥)效果最好。新复极差比较结果表明，处理1与处理4对苹果叶片生长差异显著，对经济性状影响差异不显著。2种施肥方式都能促进苹果叶片生长，有效增加叶面积系数，提高苹果等级和产量，改善苹果品质，实现增收。

Two methods of underground perfusion and foliage spray were used to study the inlfuence of humic acid water soluble fertilizer on apple tree growth, fruit quality and yield. The results showed that the treatment 1 of underground perfusion(conventional fertilization and underground perfusion 90 kg/hm2 humic acid water soluble fertilizer) was best. The treatment 4 of foliage spray(conventional fertilization and spraying humic acid water soluble fertilizer on leaf for six times) was best. Duncan test showed that there were signiifcant difference between treatment 1 and treatment 4 for the growth of apple leaves, but no significant difference for economic characters. Therefore, two fertilizing methods both could promote the growth of apple leaves, increase the leaf area coefifcient effectively, improve the grade, yield and quality of apple, increase economic beneifts.
