摘要
【目的】探究不同镁肥施用量对苹果品质的影响,筛选出合理的镁肥施用量,以期为苹果高效生产提供参考与理论依据。【方法】以昭阳区10年生的红富士苹果树为试材,采用穴施肥的方法,分别施用1 kg/株(无农家肥)、1 kg/株、2 kg/株和3 kg/株的红牛唯美肥,以不施肥为对照,研究红牛唯美肥对红富士苹果品质的影响。【结果】施加红牛唯美肥可以提高苹果的硬度、含水量、可溶性固形物质量分数、维生素C质量分数和可溶性糖质量分数,降低可滴定酸质量分数。其中红牛唯美肥浓度为1 kg/株时,红富士苹果的硬度、可溶性固形物质量分数、可溶性糖质量分数相较对照组分别增加了3.95%、3.73%和6.67%,可滴定酸质量分数为0.22%,相较对照组降低了8.33%。【结论】昭阳区红富士苹果的红牛唯美肥浓度应在1 kg/株左右的范围内进行进一步地研究,以期为昭阳区的苹果生产提供可靠的参考依据。
【Objective】The aim was to explore the effects of different application amounts of magnesium fertilizer on apple quality,and screen out the reasonable application amount of magnesium fertilizer,so as to provide reference and theoretical basis for efficient production of apple.【Methods】The 10-year-old Red Fuji apple trees in Zhaoyang District were used as test materials,and the hole fertilization method was used to apply 1 kg/plant(no farm manure),1 kg/plant,2 kg/plant and 3 kg/plant Hongniu aesthetic fertilizer,respectively.The effect of Hongniu aesthetic fertilizer on the quality of Red Fuji apple was studied with no fertilization as the control.【Results】The application of Red Bull aesthetic fertilizer could increase the hardness,water content,soluble solids mass fraction,vitamin C mass fraction and soluble sugar mass fraction of apple,and reduce the titratable acid mass fraction.When the concentration of Red Bull aesthetic fertilizer was 1 kg/plant,the hardness,soluble solids mass fraction and soluble sugar mass fraction of Red Fuji apple increased by 3.95%,3.73%and 6.67%respectively compared with the control group,and the titratable acid mass fraction was 0.22%,which was 8.33%lower than that of the control group.【Conclusion】The concentration of Red Fuji apple in Zhaoyang District should be further studied in the range of about 1 kg/plant,in order to provide a reliable reference for apple production in Zhaoyang District.
