摘要
为克服河北省苹果施肥现存的不合理现象，于１９８９～１９９２年对河北省南部、中部和北部主要苹果品种（包括金冠、元帅和国光）、不同产量水平（包括高、中、低产）的果园，连续多年采样测定，进行营养状况诊断。研究表明，目前河北省主要果园，均不同程度的存在缺素或施肥不合理的现象。根据测定结果，通过盈亏指数诊断法和综合诊断法相结合，确立并指出了；不同品种、不同产量水平听处的营养状况和需肥次序，提出了相应的施肥配方。
To overcome the incorrect fertilization of apples at present,the nutrition condition diagnosis was carried out with the materials of Golden Delicious,Delicious and Rails of 3 yield levels of production distributed in the south, the middle and the north part of Hebei Province and with the diagnosis methods of PLI (Profit and Loss index)and DRIS (Diagnosis and Recommendation intergrated System)from 1989 to 1992.The results showed that the deficiency or malfertilization happened differently to various degrees in all the orchards tested. The nutrition conditions, the mineral order of fertilizer requirement and fertilizer application suggestion of 3 varieties with 3 yield levels of production distributed in the different directs of Hebei Province were put forward.
