施肥与套袋处理对胡柚产量和品质的影响

以浙江衢州红壤丘陵区的10 a生胡柚低产林为试材,开展了施肥、套袋等措施对产量品质与土壤养分影响的研究。结果表明:套袋提高了胡柚果实的外观和内在品质。施化肥、猪粪、生物有机肥都能增加土壤中氮、磷、钾与有机质的含量,但以施生物有机肥、猪粪处理的效果最为明显,土壤速效氮、磷、钾比对照增加2~7倍,全氮、全磷、有机质含量比对照增加2~3倍,产量比对照增加60%~97%;施猪粪可提高糖酸比,改善果实内在品质。

Effect of Different Fertilization and Bagging on Fruit Yield and Quality of the Citrus Changshanhuyou

The effects of different fertilization and bagging on the yield,quality of Citrus changshanhuyou and nutrition of the soil in the hilly district of red soil in Quzhou(Zhejiang province) were studied,The result showed that coverage improved the appearance and quality of the fruits.Fertilizer, pig manure or bio-organic fertilizer could improve the percentage of N,P,K and organic matter in soil,but the effects of bio-organic fertilizer and pig manure were more obvious.The available N,available P and available K in soil increased 2 to 7 times CK,and total N,total P and organic matter increased 2 to 3 times,while the yield increased 60% to 97%.The application of pig manure could significantly increased the ratio of sugar and acid,and improved the quality of fruits.
