黄腐酸生物有机肥对脐橙产量、品质及经济效益的影响

Effects of Fulvic Acid Bio-Organic Fertilizer on the Yield, Quality and Economic Benefit of Navel Orange

通过在三峡库区开展大田试验,研究黄腐酸生物有机肥对脐橙产量、品质及经济效益的影响,结果表明:与常规施肥比,常规施肥与黄腐酸生物有机肥配施的脐橙产量明显提高9.9%,可食率、出汁率分别提高7.4%、18.5%;可溶性固形物、可溶性糖、Vc含量分别增加13.6%、10.3%、13.4%,总酸度降低5.3%;果食风味得到改善,糖酸比、固酸比分别提高20.1%、16.6%;在提高脐橙经济收益(16.3%)的同时,可以减少化肥的施用量,降低对环境的污染。

Effects of fulvic acid bio-organic fertilizer on yield,quality and economic benefit of navel orange were study by field experiments in the Three Gorges Reservoir Area.The results showed that compared with the conventional fertilization,the yield of navel orange by used the conventional fertilization+fulvic acid bio-organic fertilizer could obviously increase,and the increase rate was 9.9%,the edible rate,juice yield,content of soluble solids,content of soluble sugar and content of vitamin C was increased by 7.4%,18.5%,13.6%,10.3% and 13.4%,respectively,but the total acidity was decreased by 5.3%.The fruit taste was improved,the sugar-acid ratio and solid-acid ratio was promoted by 20.1% and 16.6%,respectively.The economic benefits of navel orange were promoted by 16.3%,at the same time,it could reduce the amount of chemical fertilizer application and the pollution to the environment.
