不同追肥措施对有机桃产量及品质的影响

Effects of Different Topdressing Practices on The Fruit Yield and Quality of Organic Peach

研究追施不同有机肥、生物肥和叶面肥等对有机栽培条件下5 a生桃(品种:北京24号)产量及品质的影响。结果表明:在每个处理基施45 t/hm2羊粪的基础上,后期追施有机肥、生物肥、喷叶面肥处理均能显著增加有机桃的产量,尤以追施有机肥并同时喷施叶面肥处理的桃产量最高;不同施肥处理对桃果实中的总糖含量和可溶性固形物含量影响差异不显著;追施不同肥料的处理显著地降低桃果Vc含量,但对桃果硬度的影响正好相反。

Effects of the topdressing of different organic fertilizer, bio-fertilizer and foliar fertilizer in organic peach orchard on the growth and quality of 5-year-old peach （variety： Beijing No 24）. The results showed that topdressing of these fertilizers could significantly increased peach yield on the basis of basal application of 45 t/hm^2 of sheep dung, especially in organic fertilizer topdressing, together with foliar spraying treatment. However, there were no significant differences in the total sugar and soluble solids content of peach fruit among different treatments. All topdressing treatments could sig- nificantly reduce the Vitamin C content of fruit, and increased fruit hardness.
