控释BB肥在苹果上的经济效益分析

目的]研究控释BB肥对苹果产量、品质和经济效益的影响。方法]采用大田试验,比较控释BB肥与普通肥料的施用效果。结果]与SF处理相比,CRF1处理的苹果产量、品质、经济效益在0.05水平显著高于SF处理;即使减少肥料的施用量,CRF2、CRF3处理的苹果产量、品质、经济效益仍不低于SF处理。从提高果实口感、减少肥料投入、增加经济效益的角度考虑,最佳施肥处理为减氮控释肥CRF3处理。结论]该研究可以为控释肥在苹果上合理施用提供依据。

Economic Benefit of Controlled Released Blend Bulk Fertilizers on Apple

Objective]The effects of controlled released blend bulk fertilizers on the yield,quality and economic benefit of the apple were studied.Method]Field experiments were conducted to study the effects of controlled released blend bulk fertilizers and common fertilizers.Result]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 weren’t lower.From the consideration of prompting the palate of fruit,decreasing the application and increasing the economic benefit,CRF3 was the optimal treatment.Conclusion]The study provided scientific evidence for applying controlled released blend bulk fertilizers on apple.
