通过田间调查,从土壤性质、苹果根系生长特点、地上部生长情况、果实产量和品质等方面对黄河冲积土苹果园土壤生产性能进行了初步的分析。结果表明,土壤质地和层次结构的差异,造成了土壤水分含量的不同,而雨季过高的土壤含水量会使土壤空气含量下降,从而使根系吸收功能降低,这是导致树体旺长、果实产量和质量较低的一个重要原因。无障碍层次的壤土和砂土较适于果树生产。

Field investigation was conducted to analyze the soil performance of the alluvial orchards in the Yellow River from the aspects of soil properties, apple root growth characteristics, shoot growth, fruit yield and quality. The results showed that the differences of soil texture and structure resulted in different soil water contents. However, the excessive soil moisture in the monsoon season decreased the soil air content and decreased the root absorption capacity, An important reason for the lower yield and quality. Unobstructed loam and sand are more suitable for fruit trees.
