在山东省两个主要蔬菜生产地区进行了 12 - 12 - 17S,12 - 12 - 17S/Cl和 15- 15- 15S三种复合肥和一种微肥 Fetrilion- combi2 ( F- C2 )在番茄、辣椒和黄瓜上的肥效试验。结果表明 ,与当地传统施肥处理相比较 ,施用 12 - 12 - 17S复合肥处理可提高三种供试蔬菜的产量和经济效益。增钾减氮是当前生产上提高蔬菜产量的有效措施。与硫酸钾型复合肥 12 - 12 - 17S相比 ,钾形态为一半氯化钾和一半硫酸钾的 12 - 12 - 17S/Cl复合肥对蔬菜产量未表现出不良影响 ;微量元素肥料F- C2的应用对几种供试蔬菜均有不同程度的增产增收作用
Three compound fertilizers, 12 - 12 - 17S, 12 - 12 - 17S / Cl and 15 - 15-15S, and Fetrilion - combi2 (F - C2), a micronutrient, were applied to two major vegetable producing areas in Shandong Province. Pepper and cucumber on the fertilizer effect test. The results showed that the application of 12 - 12 - 17S compound fertilizer increased the yield and economic benefits of the three tested vegetables compared with the traditional fertilization treatment. Adding potassium and reducing nitrogen is an effective measure to increase the yield of vegetables in the current production. Compared with potassium sulfate compound fertilizer 12 - 12 - 17S, 12 - 12 - 17S / Cl compound fertilizer with half potassium chloride and half potassium sulfate did not show any adverse effect on vegetable yield. Trace element fertilizer F - C2 The application of several kinds of vegetables for testing have different levels of increase income
