摘　　要：为考察含腐殖酸复合肥对农作物生长和产量的影响,以番茄为试验对象,开展了田间小区试验。试验共设3个处理,分别为常规施肥、常规施肥+普通复合肥、常规施肥+含腐殖酸复合肥。结果表明:与常规施肥处理相比,含腐殖酸复合肥处理的土壤全氮、有效磷、速效钾、有机质质量分数分别增加0.23 g/kg、6.18 mg/kg、20.51 mg/kg、2.03 g/kg,pH降低0.39,孔隙度增加1.58%,容重降低0.13 g/cm^(3);番茄坐果率提高4.34%,产量提高38.05%。在常规施肥的基础上施用含腐殖酸复合肥,可以改善土壤理化性状,提高农作物产量。In order to investigate the effect of compound fertilizer containing humic acids on crop growth and yield,a field plot experiment is conducted with tomato as the experimental object.There are three treatments in the experiment,namely conventional fertilization,conventional fertilization and common compound fertilizer,conventional fertilization and compound fertilizer containing humic acids.The results show that comparing with conventional fertilization,the mass fractions of total nitrogen,available phosphorus,available potassium and organic matter in the soil treated with compound fertilizer containing humic acids increase by 0.23 g/kg,6.18 mg/kg,20.51 mg/kg and 2.03 g/kg respectively,pH decrease by 0.39,porosity increase by 1.58%,and bulk density decrease by 0.13 g/cm^(3).The fruit setting percentage and yield of tomato increase by 4.34% and 38.05%respectively.Applying compound fertilizer containing humic acids on the basis of conventional fertilization can improve soil physical and chemical properties and increase crop yield.
