沃叶桃树科学施肥建议 根据品种和地势不同不一样
一、存在问题和施肥原则针对桃园用肥量差异较大，肥料用量、氮磷钾配比、施肥时期和方法不合理等问题，提出以下施肥原则：1.加强有机肥施用比例，依据土壤肥力和早中晚熟品种及产量水平，合理调控氮磷钾肥施用水平，注意钙、镁、硼和锌的配合施用；2.不同品种的春季追肥时期要有差别，早熟品种较晚熟品种追肥早，追肥次数少；3.与优质栽培技术相结合，夏季易出现涝害的平原地区需进行起垄、覆膜等土壤管理工作；干旱地区提倡采用地膜覆盖，穴贮肥水技术。
二、挑树施肥建议早熟品种、土壤肥沃的果园，树龄小或树势强的桃树，全年平均每亩施有机肥1－2方或人粪尿、沼液1500－2500公斤；晚熟品种、土壤瘠薄的果园，树龄大或树势弱的桃树施有机肥2－3方或人粪尿、沼液2000－3000公斤。
1.目标产量3000公斤／亩的桃园，施氮肥（N）12－18公斤／亩，磷肥（P205）10－12公斤／亩，钾肥（K20）20－26公斤／亩；
2.目标产量2000公斤／亩的桃园，施氮肥（N）10－15公斤／亩，磷肥（P205）7－10公斤／亩，钾肥（K20）17－20公斤／亩；
3.目标产量1500公斤／亩的桃园，施氮肥（N）9－12公斤／亩，磷肥（P205）5－8公斤／亩，钾肥（K20）12－15公斤／亩。
全部有机肥作基肥最好于秋季9－10月份施用，其次是春季土壤解冻后施用，采用开沟上施方法施用，人粪尿和沼液作追肥分5－6次浇施。40%的氮肥和钾肥及50%的磷肥也一同基施，其余氮磷钾肥按生育期养分需求分次追施；化肥施用一般在桃树萌芽期（3月初）、硬核期或花芽生理分化期（5月中旬－6月下旬）和果实膨大期追肥2－3次（早熟品种2次、晚熟品种3次）。对上年早期落叶或负载量过高的泉园，应加强根外追肥，萌芽前可喷施2－3次1%－3%的尿素，萌芽后至7月中旬之前，每隔7天1次，按2次尿素与1次磷酸二氢钾的比例喷施，浓度为0.3%－0.5%。如施用有机肥数量比较多，则秋季基施的氮、钾肥可酌情减少2－4公斤／亩。
可以用针对的叶面肥！例翠姆果树专用叶面肥，比较有针对性，就看你要施什么肥了！基肥，萌芽肥，开花后，硬核期，果实膨大期施肥，及采后肥！一个阶段用法用量不同，施肥方式不同！
