摘要
采用随机区组设计,研究了沼渣与化肥配合施用对大豆生长发育、产量和品质,以及耕层土壤理化性质的影响。结果表明:与常规施肥相比,沼渣与化肥配合施用后,茎粗、根容和根瘤数均有所增加,植株生长表现较好;常规施肥+沼渣30.0×103kg.hm-2产量显著高于其它处理,粗蛋白含量较常规施肥处理提高1.12%,含油量提高0.04%,是大豆较优的施肥配比组合。
The effect of matching application of biogas residues and chemical fertilizers on soybean development,yield,quality,and physical and chemical properties of plough layers in soybean field were studied by randomized block design.Compared with the conventional fertilization,pods per plant increased by 4.4-9.9;the average grain number per plant increased by 22.0-29.6;100-seed weight increased 0.79-1.20 g;and the yield increased by 6.3%.The same trend appeared in crude protein content,which increased by 1.12%.Among all the treatments,matching application of conventional fertilizers and biogas residues（30.0×103 kg·hm-2）is the optimum treatment for soybean.
