摘 要:采用实地调查和问卷的方式,对河北省9个大面积种植李树的地区进行了施肥现状调查。通过对调查资料汇总,从中发现了重施氮磷肥,轻钾肥及中、微量元素肥料;施肥时期和方法欠科学;配方施肥用量少等一系列问题。结合李树的生长特点及施肥中存在的问题,提出了相应的建议,要广开肥源,重视有机肥以及配方肥的施用;施用腐熟的有机肥;可适当施用叶面肥;施肥方法和时期要合理。从而为李树的增产、高产和优产制定相应的施肥技术和对策。In this paper, the situation of fertilizer use for plum tree was analyzed using the investigation and questionnaires to 9 big plum tree planting areas of Hebei province.
