摘要
研究腐植酸钾对黄冠梨土壤中腐植质、氮、磷、钾含量的影响。结果表明:腐植酸钾显著提高土壤腐植质含量和速效氮、磷、钾含量,对土壤中全量养分影响不大。腐植酸钾具有改良土壤,增加肥效作用。
Effects of potassium humate on the soil humus, nitrogen, phosphorus, potassium in Huangguan pears were stud led. The results indicated that potassium humate could increase the contents of humus,nitrogen,phosphorus and potassi- um in soil greatly,but couldn＇t affect the entire nutrients of soil any more. Potassium humate can make the constuction of soil better and improve its fertilizer efficiency.
