摘　　要：以日光温室栽培4年生油桃品种‘艳光’为试材,通过叶面喷施不同浓度的沼液,研究了沼液对温室油桃叶片营养元素及果实品质的影响.结果表明:喷施沼液对‘艳光’油桃叶片营养及果实品质都有促进作用,其中以喷施75%的沼液处理效果最好.当用75%的沼液连续处理4次后,油桃叶片营养元素含量N、K、Fe、B、Mn、Zn、P分别较CK增加了4.86%、12.97%、17.41%、13.45%、8.5%、5.4%、12.95%;果实可溶性糖含量增加12.6%,VC含量增加了20.2%.Nectarine（Prunus persica var.Nectarine Maxim.cv.＇Yanguang＇） of four-year old was selected as experimental material.Impact of biogas on the leaf nutrition and quality of fruit were studied in this article by spraying different concentrations of biogas.The results showed that biogas improved both the alimentation of lamina and quality of nectarine.The optimum of biogas was 75 %.The content of N,K,Fe,B,Mn,Zn and P in leaves treated with 75 % biogas for 4 times increased 4.86 %,12.97 %,17.41 %,13.45 %,8.5 %,5.4 % and 12.95 %.The soluble solids content and VC content increased 12.6 % and 20.2 %.
