摘　　要：从肥料使用的角度,阐明沼液对黄瓜生长质量及土壤化学性质的影响,在不同浓度的处理中,测定和分析黄瓜苗期沼液定期施肥处理幼苗生长形态、生理和土壤基本化学性状。结果表明:沼液施肥显著提高幼苗株高、茎粗、根长,40%浓度沼液的壮苗指数比CK提高21.5%;不同沼液施肥明显提高黄瓜幼苗叶片叶绿素总量、净光合速率(P_(n))、胞间CO_(2)浓度(C_(i))、气孔导度(G_(s))和蒸腾速率(T_(r)),80%沼液浓度叶绿素含量最高,60%浓度沼液的幼苗叶片气孔导度和蒸腾速率高于其他处理差异显著;与CK相比,沼液的施用可以提高可溶性蛋白、可溶性糖和根系活力;沼液施肥显著提高黄瓜生长土壤的pH、有机质质量分数、速效磷含量,促进土壤有机质含量增加3.77%(P<0.05)。因此,沼液施肥可明显提高黄瓜幼苗质量,改善黄瓜根系土壤基本化学性状。In order to understand the effects of fertilization with biogas slurry of different concentrations on the growth quality of cucumber seedlings and soil chemical properties,the growth morphological indexes,physiological indexes and soil chemical indexes of cucumber seedlings treated with biogas slurry of different concentrations were measured.The results showed that biogas slurry fertilization significantly increased the plant height,stem diameter and root length of seedlings,and the strong seedling index of 40%biogas slurry was 21.5%higher than that of CK.Different biogas slurry fertilization significantly increased the total chlorophyll,P_(n),C_(i),Gsand Trof cucumber seedlings.The chlorophyll content of 80%biogas slurry was the highest,Gsand T_(r) of seedlings with 60%biogas slurry changed significantly.Compared with CK,application of biogas slurry significantly increased soluble protein,soluble sugar and root activity.Fertilization with biogas slurry significantly increased pH,organic matter mass fraction and rapid available phosphorus content of cucumber growing soil,and promoted soil organic matter content to increase by 3.77%(P<0.05),therefore,fertilization with biogas slurry can significantly improve the quality of cucumber seedlings and the basic chemical properties of cucumber root soil.
