摘　　要：为探究猪血多肽和蚯蚓裂解液叶面喷施对小麦产量及品质的影响,于小麦拔节期、孕穗期、抽穗期喷施不同浓度的叶面肥尿素、猪血多肽、蚯蚓裂解液,空白和喷清水作为对照。结果表明,猪血多肽500倍液处理可显著提高小麦产量及其构成,相比清水对照,每穗粒数、穗数、千粒重、实际产量分别提高11.2%、13.3%、9.9%、11.3%。猪血多肽处理籽粒蛋白质与湿面筋含量呈现随肥液浓度的升高而升高的现象。蚯蚓裂解液2000倍液处理每穗粒数、穗数、千粒重、实际产量相比清水对照分别提高13.2%、9.7%、7.2%、18.5%。等氮量情况下,猪血多肽250倍液、蚯蚓裂解液200倍液处理产量及其构成因素、矿质养分积累量均低于等氮量尿素处理,并未达到增产效果;猪血多肽250倍液、蚯蚓裂解液200倍液处理蛋白质含量显著高于尿素处理,分别提高约41.6%、11.1%,叶面喷施猪血多肽和蚯蚓裂解液对籽粒蛋白质含量的影响主要为含氨基酸功能物质,而非单纯氮素的影响。综合考虑,猪血多肽500倍液处理对整体优化、提升小麦产量及品质效果最佳;蚯蚓裂解液2000倍液可以有效促进小麦对其他养分的吸收,实现较高产量。To investigate the effect of foliar spraying of pig blood peptide and earthworm lysate on wheat yield and quality,different concentrations of foliar fertilizers,i.e.,urea,pig blood peptide and earthworm lysate,were sprayed on wheat at the nodulation,gestation and tasseling stages,and blank and water were used as controls.The results showed that porcine blood polypeptide 500 times solution significantly improved wheat yield and its composition,compared with the water control,the number of spike grains,number of spikes,thousand grain weight and actual yield increased by 11.2%,13.3%,9.9%and 11.3%,respectively.The protein and wet gluten content of pig blood polypeptide treated seeds showed an increasing trend with increasing fertilizer concentration.The number of grains per spike,number of spikes,thousand grain weight and actual yield were increased by 13.2%,9.7%,7.2% and 18.5%,respectively,the earthworm lysate diluted 2000 times compared with the water control.In the case of equal nitrogen,the yield and its constitutive factors and mineral nutrient accumulation of pig blood polypeptide 250 times solution and earthworm lysate 200 times solution treatments were lower than that of equal nitrogen urea treatment,and did not increase the yield.The protein content of porcine blood polypeptide 250 times solution and earthworm lysate 200 times solution was significantly higher than that of urea treatment by 41.6%and 11.1%,respectively.The effects of foliar spraying pig blood polypeptide and earthworm lysate on the protein content of seeds were mainly amino acid-containing functional substances rather than the effect of nitrogen alone.With a all things considered,pig blood polypeptide diluted 500 times solution had the best effect on overall optimization and improvement of wheat yield and quality;earthworm lysate 2000 times solution treatment could effectively promote the absorption of other nutrients in wheat and achieve higher yield.
