腐植酸水溶肥料在鲁中地区蔬菜上的应用探究

Study on the Application of Humic Acid Water-soluble Fertilizer in Vegetables in Central Shandong Province

为探究腐植酸在设施蔬菜上的应用效果,推进化肥减量增效,以菠菜、油菜、番茄和辣椒为试材,每类蔬菜设置3个处理,并对每类蔬菜的生物学性状、产量及经济效益进行分析。结果表明:蔬菜生长期喷施腐植酸水溶肥料可改善蔬菜生物学性状,使植株生长健壮,株高增高,挂果数增多,果重增加,蔬菜产量和经济效益提高。其中,在果实类蔬菜番茄和辣椒上作用效果更为明显,可实现更大幅度的增产,获得更高的经济效益。因此,建议在鲁中地区设施蔬菜上推广施用腐植酸水溶肥料,尤其是在果实类蔬菜上大力推广应用。

In order to investigate the application effect of humic acid on facility vegetables and promote the reduction of chemical fertilizer application and enhance its efficiency,three treatments were applied to spinach,rape,tomato and pepper,and the biological characters,yield,and economic benefits of these vegetables were analyzed.The results demonstrated that the application of humic acid water-soluble fertilizer during the vegetable growing period could improve biological characters such as plant growth,height,fruit number and fruit weight,and increase vegetable yield and economic benefits.This effect was particularly pronounced for fruit vegetables such as tomato and pepper with significant increases in both yield and economic benefits.Therefore,it was suggested to applicate humic acid water-soluble fertilizer into facility vegetables especially fruit vegetables in central Shandong Province.
