摘　　要：采用田间小区试验方法进行了硅钾肥在番茄上肥效试验研究,结果表明,硅钾肥对番茄的生物学性状、经济性状有重要影响,与对照相比,每株叶片增加了3.2片,单株果数增加3.1个,株高增加5.7 cm,单果重增加10.3%;可以明显提高番茄产量及降低番茄硝态氮含量,产量增加了10.4%,硝态氮含量下降了16.9%。Silicon-potash fertilizer is a new kind of mineral potash fertilizer made of insoluble rock containing potassium, which is citrate soluble. Its effects of application on tomato were proved in field experiment. The results showed that the silicon-potash fertilizer could obviously affected the biological traits and economic properties,increase the yield and decrease the NO3-N of tomato.
