Abstract

[Objective]The research aimed to solve the unreasonable fertilization problem in the protected vegetable cultivation in Ankang city.[Method]According to the fertilization status of the protected tomato cultivation in Ankang city,the potassium fertilizer with different amount was applied to study the effects of potassium fertilizer on the yield,quality and economic benefits of tomato.[Result]Under the conditions of the same application amount of nitrogen and potassium fertilizers,the yield and the economic benefits of tomato were increased with the increasing of the application amount of potassium fertilizer.When the application amount of potassium fertilizer was 180 kg/hm2,the average yield of tomato was 86 000 kg/hm2,being 50.9% higher than that of treatment without potassium fertilizer,and the yield increase for unit potassium fertilizer cost was 80.6 kg/yuan.Adding the application of potassium fertilizer could enhance the yield and economic benefits of tomato significantly,increase the soluble sugar content of tomato,lower the acidity and improve the tomato quality.[Conclusion]The application amount of potassium fertilizer should be appropriately added in the production of protected vegetable in Ankang city.
