摘要
通过对晋中果园土壤养分取样化学分析,较全面地了解了其有机质、全氮、有效磷、速效钾及部分微量元素的含量情况,指出影响晋中水果产量与质量的原因之一是养分不均衡,阐述了平衡施肥的必要性。
By the chemical analysis of Jinzhong orchard's soil,we have an intimate understanding of the content:organic matter,nitrogen, effective phosphorus, quick-acting potassium and exploded trace elements. This paper points out that one of the reason to impair the quantity and quality of fruits is the imbalance of soil nutrients, and expounds the necessity of applying fertilizer on balance.
