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 results showed that the content of N, P and K in this type of soil was rich, the contents of available nitrogen and available phosphorus were middle-lower, while the contents of Ca, Zn content is not enough. Under the interaction of multiple nutrition factors, the most important factors affecting the intrinsic quality of fruits were Fe and available potassium, followed by Zn and total P. The available nitrogen content of topsoil was 30 ~ 127mg / kg and the available phosphorus content was 18 ~ 107mg / kg, available potassium content of 50 ~ 164mg / kg, the appropriate ratio of 1: 0.8: 1.4.
