摘要
相同氮磷基础上，加工番茄施用等钾量的不同钾肥品种，产量均明显增加，增收903．00-2563．80元／hm^2。以氯化钾效果最好，增产14．58％；氯化钾配施硫肥产量次之，但品质稍优于前者；单施硫酸钾处理增产6．76％，硫酸钾镁肥的产量、品质较硫酸钾处理均有所提高，两个硫酸钾处理产量不及两个氯化钾处理但提高了产品品质，氯化钾配施硫肥和硫酸钾镁肥处理均增加了相对单株果数。
Application of same quantity, fertilizer from the different K-fertilizer varieties has signifi-cantly increased the yield of processing tomato based on the same amount of N,P. Application of potassimn chlorate to processing tomato has the best result,increasing yield by 14.58% ;The treatment of potassium chlo-rate applied with sulphur fertilizer gives less yield, but the quality is better than the former; The yield can be in-creased by 6.76% only by application of potassium sulfate. The treatment with fertilizer of magnesium potassium sul- fate provides higher yield and quality than that with potassium sulfate. The yield of the two trealments with potas-sium sulfate is lower than that of the two treatments with potassium chlorate, but the quality of yield of the former is increased. The relative fruit number per plant is increased beth by the treatment with potassium chlorate applied with sulphur fertilizer and the treatment with magnesium potassium sulfate.
