在严重缺钾缺硼的冲积性土壤上设置定田间试验.结果表明,施用钾肥,油菜籽增产24.2～27.2%,施用硼肥增产10.5～19.9%.土壤有效硫虽属较高水平,施用硫肥效果欠佳,但钾硫、硼硫之间有显著的正交互效应.
A field experiment was set up on alluvial soil with deficient potassium and boron deficiency. The results showed that applying potassium and rapeseed increased yield by 24.2-27.2% and application of boron fertilizer increased by 10.5-19.9% Fertilizer effect is poor, but there is a significant positive interaction between potassium sulfur and boron sulfur.
