Study on the relationship between the soil nutrient elements and the apple fruit quality of the newly reclaimed apple orchard in Taihang mountain gneiss area

The relationship between the soil nutrient elements and the Fuji apple fruit quality of the newly reclaimed apple orchard in Taihang mountain gneiss area was studied in Gangdi Village，Neiqiu County，Hebei Province in 1998 and 1999.The results show that in this kind of soil，the contents of total N ，P and K are abundant．available N ，P are below medium,Ca，Zn are insufficient.Under the interaction of nutrient elements，the main elements that affect the inner quality of fruit are Fe and available K ，the next are Zn and total P To produce high quality apple fruit，the contents of available N ，P and K are 3O～127mg／kg，l8～107mg／kg and 50～164mg／kg respectively in the upper soil layer，and the suitable proportion of available N ．P．K in soll is l：0．8：1．4.
