Abstract: A field experiment was conducted to study the effects of controlled release fertilizers blended withcommon fertilizers on yield, quality, and economic benefit of apple in order to provide scientific evidence and technicaladvice for applying controlled release fertilizers on apple. The result showed that the available nutrient in soil of SFtreatment decreased gradually in a growing season. The controlled release fertilizers blended with common fertilizerssolved the problem of nutrient's slow release in a short time after being applied and met with the nutrient requirementof plant in a growing season. The application rate of CRF1 was the same as that of SF, but the yield, quality and economic benefit of CRF1 were better than that of SF. The application rate of CRF2 and CRF3 was lower than that of SF,but the yield, quality and economic benefit of CRF2 and CRF3 weren't lower. Considering prompting the palate offruit, decreasing the application and increasing the economic benefit, the CRF3 was the optimal treatment.

Key words: Coated controlled blend bulk fertilizers, Apple, Economic benefit
