摘　　要：以水和一定浓度的酸溶液为浸取液,测定了钾钙肥中的钾、钙在不同振荡温度、不同振荡时间和不同pH值下的溶出率,并分析其溶出规律;模拟植物吸收养分,测定了钾、钙的累积溶出率,验证了其缓释性,为钾钙肥的使用提供依据。With water and a calcium in different conditions certain concentration acid as extracted of oscillation temperature, oscillation tired, the dissolution rates ot potassmm, time, pH value are determined to analyze the dissolution behaviors for a new type of potassium-calcium fertilizer; The accumulative dissolution rates of potassium, calcium are determined by simulating nutrient absorption of plant to verify slow release property of potassium-calcium fertilizer and provide basis for use of potassium-calcium fertilizer.

关 键 词：钾钙肥 氧化钾 氧化钙 溶出率 累积溶出率 缓释性
