摘　　要：以"芬达F1"番茄为试材,研究了不同施钾量对番茄产量和经济效益的影响。结果表明:在银川平原的温室土壤中,钾肥对温室番茄的增产有一定的作用,但施量过大,增产作用反而不明显,当667m2施纯钾达到63.8kg时可实现产量最大化,而当667m2施纯钾量达到20kg时,边际产量和投入产出比达到最优。Taking‘Fenda F1＇tomato as material,the yield and economic benefit of Solanum lycopersicum with different potash fertilizer application rate were studied.The results showed that there was an increasing production of Solanum lycopersicum while applying potash fertilizer on greenhouse.The yield was the highest while 63.8kg potash fertilizer applying in 667m^2,marginal yield and input-output ration were optimal with 20kg potash fertilizer in 667m^2.
