摘要
对太行山片麻岩区新垦苹果园土壤营养因素与红富士果实品质关系的研究结果发现,该类型土壤中N、P、K含量较丰富,速效氮、速效磷含量中等偏下,而Ca、Zn含量不足。在多种营养因素相互作用下对果实内在品质影响最大的因素是Fe和速效钾,其次是Zn和全P;生产优质苹果的表层土壤速效氮含量为30～127mg/kg,速效磷含量为18～107mg/kg,速效钾含量为50～164mg/kg,其适宜比例为1:0.8:1.4。
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 30 -127mg/kg,18- 107mg/kg and 50-164mg/kg respectively in the upper soil layer,and the suitable proportion of available N, P, K in soil is 1:0.8:1.4.
