水溶肥配合有机肥在天水苹果园的肥效试验

Fertilizer Efficiency Experiment ofWater Soluble Fertilizer Combined with Organic Fertilizer in Tianshui Apple Orchard

以俄矮2号花牛苹果果园为研究对象,通过对分别施用水溶肥+有机肥、磷酸氢二铵+有机肥、普通复合肥溶液的果园果树树体发育,苹果品质进行记录和分析,探讨不同施肥方式对苹果生长的影响。结果表明,试验所选的水溶肥和磷酸二氢铵水溶液配合有机肥对俄矮2号树体发育、产量、品质均具有正面影响,其中氮、磷、钾为21-21-21比例的水溶肥溶液配合有机肥对俄矮2号树体发育和果实品质影响效果最好。

Taking E'ai No.2 Huaniu Apple orchard as the research object,the fruit tree development and apple quality of the orchard were recorded and analyzed by applying water-soluble fertilizer+organic fertilizer,diammonium hydrogen phosphate+organic fertilizer and common compound fertilizer solution,and the effects of different fertilization methods on apple growth were discussed.The results showed that the water-soluble fertilizer and ammonium dihydrogen phosphate aqueous solution combined with organic fertilizer had positive effects on the growth,yield and quality of E'ai No.2 tree,among which the water-soluble fertilizer solution with 21-21-21 ratio of nitrogen,phosphorus and potassium combined with organic fertilizer had the best effects on the growth and fruit quality of E'ai No.2 tree.
